AC Schnitzer

Source - AC Schnitzer
ACS 3 Sport: Everyday is M-otion AC Schnitzer refines the fastest 3-Series Coupé When beads of perspiration form on the brow of experienced sports car drivers, it's not necessarily down to a faulty air conditioning system. With the 420 V8-HP of the BMW M3, the ACS3 Sport catapults even its keenest challengers into the rear view mirror. The sporting coupé is ideal for anyone seeking to gain advantage on twisting tracks. A normal M3 would be a tough competitor here, because in comparison with the 'civilised' 3-series Coupé it has a totally different axle construction. With racing suspension developed on the legendary Nürburgring, AC Schnitzer has succeeded in refining the handling potential of the chassis even further. And fitted with the Short Shift from Aachen, the ACS3 Sport becomes the automotive hero of the day: No-one is changing gears faster! Best of all: The vehicle loses nothing of its qualities as a daily driver. Instead, AC Schnitzer magics even more M-otion into everyday life, for example when the Aachen exhaust system plays its bewitching baritone in a road tunnel. The left/right system with two tailpipes per side, linked into a horizontal figure of eight, is however a visual work of art. In a play on the mathematical symbol for 'infinity', at the same time it symbolises the powerful reserves of the vehicle which reaches 100 km/h from a standing start in an effortless 4.8 seconds. No less carefully arranged are the aerodynamic attachments, which for AC Schnitzer are always more than mere visual decoration. At the rear, a diffuser of visible carbon presses the car down onto the tarmac as if there were magnets below the road surface. The front spoiler is also made from this high quality material, and is supported against the front skirt with alloy struts as in motorsport. Further downforce is provided by a subtle rear roof spoiler and rear wing which also give the body exciting new contours. Side skirt extensions, in particular when combined with the white paint of the photo model, give the profile an aura of stature and dynamism. Finally the AC Schnitzer racing rims Type VI embody pure culture, on the ACS3 Sport in sizes 9.0J x 20' on the front and 10.5J x 20' on the rear. The combination of Y-spokes and contrasting five fork spokes superimposed in two planes, produces a design that is as exciting as it is elegant. Further highlights of course include the forged wheel Type V in 20'. With its strikingly curved, interrupted spokes, it not only looks superb but thanks to the lightweight construction method, keeps the unsprung weight to a minimum. A no less attractive alternative is the Type IV racing wheel in silver - and with trendy black finish as 'Magic Black'. And naturally AC Schnitzer continues the theme of sports performance in the driver's workplace, offering attractive and ergonomically perfect aluminium controls for the gearknob, handbrake handle, pedals and i-Drive controller. A carbon interior trim and sports airbag steering wheel are also available on request.

THE FIRST-EVER BMW X6 SPORTS ACTIVITY COUPE: BMW's All-New X6 xDrive35i and X6 xDrive50i Make World Debuts at Detroit Auto Show in 2008BMW will once again introduce a ground-breaking idea to the world and the creation of a new segment with the debut of its all-new X6 Sports Activity Coupe at the 2008 Detroit Auto Show in January. The all-new vehicle redefines the very notion of a coupe -- with five doors and four sculpted seats, a higher ride and loads of cargo space. It defies coupe conventions in one jaw-dropping look, combining coupe agility and SAV versatility, taking the coupe to a higher level.As the world's first
Sports Activity Coupe, the BMW X6 will be available in two engine variants: the xDrive50i (4.4 V8 engine, 400 hp, 450lb.-ft torque) and the xDrive35i (3.0 inline six-cylinder engine, 300 hp, 300 lb.-ft torque), both with Twin Turbo and direct injection. The BMW X6 offers unique features and performance ability in a combination unmatched by any other vehicle. The new BMW X6's design combines the sporting elegance of a large BMW Coupe with the powerful presence of a BMW X model.The BMW X6 comes as standard with BMW's intelligent xDrive all-wheel-drive technology with electronic control for variable distribution of drive power between the front and rear axles, consistently adjusted to driving conditions at all times and in all situations.Featured for the first time as standard in the BMW X6, Dynamic Performance Control likewise ensures variable distribution of drive forces between the two rear wheels. Dynamic Performance Control incorporates an advanced computer control and an innovative rear differential incorporating two planetary gearsets and two clutch packs that enables the system to multiply torque on an individual rear wheel. The result is that Dynamic Performance Control can help steer the vehicle by directing torque to either of the rear wheels. Unique the world over, this cutting-edge technology is effective whether the driver is accelerating or decelerating and significantly enhances steering precision and, as a result, the agility of the vehicle at any speed. In fast corners with abrupt steering maneuvers or with the driver suddenly releasing the gas pedal, Dynamic Performance Control serves to improve the stability of the entire vehicle, thus allowing the driver to safely enter and enjoy new dimensions of driving dynamics. Finally, on slippery or uneven surfaces, Dynamic Performance Control provides the further advantage of even safer and more stable traction.The new V8 engine with Twin Turbo technology and direct gasoline injection, is likewise making its world debut in the BMW X6. Displacing 4.4 liters, this eight-cylinder with maximum engine output of 400 hp and peak torque of 450 lb-ft available over an unusually large range of engine speed from 1,800-4,500 rpm, is the most powerful engine ever seen in a BMW X Model.The new eight-cylinder is indeed truly impressive not only through its outstanding thrust and pulling force, but also through its compact dimensions. For this is the first eight-cylinder gasoline engine in the world to feature its turbocharger in the V-section between the two rows of cylinders.Hence, the BMW Sports Activity Coupe is an absolutely exceptional vehicle also beyond the direct range of BMW X Model competitors, ensuring unparalleled performance in all situations, regardless of road and surface conditions.Unique design: dynamic line, powerful presence.In its design, the BMW X6 definitely offers all the DNA of a genuine BMW X Model, interpreted however, in a brand-new, extremely sporting style. Indeed, the design language of this new model is the authentic visualization of the outstanding driving characteristics offered by the BMW X6, mainly through intelligent BMW xDrive all-wheel-drive technology and Dynamic Performance Control.Various design features typical of BMW also stand out in the car's details, ranging from the BMW kidney grille to the dual round headlights optically 'cut off' at the top and the powerful contour line along the side, all the way to the horizontal lines at the rear emphasizing the sheer width of the vehicle.Front end with clear and dynamic orientation to the road.Just one look at the front end of BMW's new Sports Activity Coupe demonstrates the powerful presence of this unique vehicle. Due to the greater share of surfaces finished in body color, the front end looks lower and even more dynamic, clearly emphasizing the powerful orientation of the BMW X6 to the road. This DNA so typical of BMW is also demonstrated in the design of the hood and in the vertically positioned BMW kidney grille, with fins finished in a sophisticated titanium color on the xDrive50i and in black on the xDrive35i.Large air intakes are positioned far to the outside for more than just meeting the cooling requirements of the powerful engines. Rather, interacting with the side panels extending far to the inside over the headlights, the air scoops provide clear orientation towards the wheels, emphasizing the powerful stance of the vehicle on the road.The headlights themselves merge in a dynamic sweeping line into the side panels, the surface of the engine compartment lid is divided by striking lines tapering out towards the BMW kidney grille like the borderlines of the engine compartment lid at the sides.Side view: dynamic roofline, muscular surfaces.The unique proportions of the new BMW X6 stand out particularly clearly from the side. For example, the short body overhang at the front emphasizes the dynamic look of the vehicle, while the roof line tapering out gently towards the rear and the long body overhang on the rear section, add to the stretched silhouette of a genuine coupe.At the rear, the side window frame features the 'counter-swing' at the bottom of the D-pillar, so well-known as the 'Hofmeister kink' and chrome surrounds on the windows featured as standard distinguish the BMW X6 xDrive50i from the xDrive35i.The high waistline and powerfully contoured wheel arches both front and rear, moving the visual center of gravity to the middle of the vehicle and thus bearing testimony to all-wheel drive, are further significant features of the DNA of a BMW X Model.The side panel is split by two lines with striking contours, moving slowly towards one another at the front end of the vehicle to create a wedge-like impression symbolising the forward-pushing, powerful character of the BMW X6. While the lines at the side highlight the supreme elegance of the car, the special design of the surface gives the BMW X6 a particularly powerful look from this perspective. Striking interaction of the concave and convex surfaces emphasize the muscular look of the vehicle, providing the BMW X6 with an excellent balance of visual power and stylish presence.Strong shoulders and a powerful stance from the rear.Likewise, the rear end of the BMW X6 offers a thrilling combination of elegance, sportiness and robustness in full harmony with one another. The muscular bumper and protection cover on the underfloor; the striking light edge along the lower section of the bumper, highlighting the ride height of the BMW X6; and the vehicle proportions that are so typical of a coupe, are all examples of classic design elements that stand out clearly and convincingly in the particular style and looks of a BMW X Model.The entire rear end is subdivided by horizontal lines giving the rear end a wider look and emphasizing the powerful stance and road-holding of the entire vehicle. The greenhouse with its strikingly low rear window, in turn, tapers out smoothly towards the rear, with the rear lid featuring a distinct air flow lip, further proof that this unique new vehicle is a genuine coupe in both its looks and style.Even the special design of the rear light clusters takes the unique character of the BMW X6 into account, the L-shape so typical of a BMW X Model being re-interpreted and now boasting a particularly dynamic sweep from one side to the other. Extending far into the side panels, the rear-light clusters bring out and accentuate the entire width of the vehicle also through its night design.Sportiness and luxury within the interior.To the very last detail, the interior of the BMW X6 offers a unique synthesis of luxury, sporting dynamics, and powerful style. Tense surfaces blending into one another symbolize the active character of BMW's Sports Activity Coupe, sporting features such as kneepads on both sides of the center console, paddles on the sports steering wheel featured as standard, and the fine scale on the circular instruments creating an excitingly different driving experience in the new BMW X6 both on the road and off the beaten track.Like all BMW X Models, the new Sports Activity Coupe offers the occupants of all four seats an elevated, commanding seating position. In particular, this gives the driver a clear feeling of being perfectly in control of his BMW X6 in all situations. In conjunction with the cockpit simply begging the driver to drive his vehicle in an active style, this creates an innovative impression of genuine, all-out sportiness.A further point distinguishing the world's first Sports Activity Coupe from the other BMW X Models is the sporting design of the individual rear seats separated from one another through the center console, the high-rising side supports, and the integrated headrests on all four seats.The BMW X6 is the only car in the complete segment of BMW X Models to feature a sports steering wheel with gearshift paddles as standard, which enable the driver to shift gears manually on the six-speed automatic transmission for enhanced smoothness and response at all times. Furthermore, multifunction buttons on the steering wheel operate the telephone and audio systems quickly, smoothly and without the slightest distraction, while two additional buttons may be programmed individually according to the driver's personal preferences.The instrument panel is dominated by dual round instruments with fine scales reminiscent of motorsport as clear visual reference to the sporting character of the BMW X6. The galvanized trim rings on the instrument panel clearly accentuate the exclusive character of the vehicle's interior, with the same high-quality metal shimmer being boasted on the rotary knobs, the door openers, on the gearshift lever knob, and on the brackets within the air vents.The new kneepads on the center console stand out clearly as a particularly sporting feature offering the driver and front passenger additional stability in maneuvers in city traffic and when driving off-road under tough conditions.Visibly and tangibly sophisticated, premium quality surfaces make the interior of the BMW X6 a genuine experience to feel and behold at all times. Through their special quality designed for lasting strength and resistance, the interior surfaces also emphasize the superior robustness of the vehicle committed to off-road use whenever required.Lots of space, lots of customization options.Wide opening rear doors facilitate access to the two rear seats, while head-room in the rear is unusually generous for a coupe-seat height of 37.2 inches guarantees supreme comfort and convenience, even for tall passengers.A wide range of materials and colors highlighting the sporting character of the BMW X6 adds to the individual style and personality of this unique vehicle. The exterior paintwork, for example, comes in a choice of no less than ten exterior colors, eleven leather options and three trim options ensure a wide range of individual style and choice.Trim in ash grain has been created especially for BMW's Sports Activity Coupe. And while the wood variant exudes a particular touch of discreet exclusivity, the sweeping polish on the aluminum version shows a clear and distinct reference to motorsport.The passenger and luggage compartment on the BMW X6 are distinctly separated from one another in the usual style one would expect of a fully-fledged coupe. Offering almost 25.6 cu ft of storage space, the luggage compartment behind the rear seats of the BMW X6 is far larger than in a conventional coupe, providing enough space to store four full-size golf bags in the luggage compartment-even with four people riding in the vehicle.BMW's new Sports Activity Coupe also boasts a firm, folding cover on top of the luggage compartment that can be folded at stowed beneath the floor for convenient transportation of bulky objects. To increase the transport capacity available, the rear-seat backrests may be folded down in an asymmetric split, expanding loading capacity to a substantial 59.7 cu ft.An automatic tailgate opening and closing function is available as an option on the BMW X6 allowing the driver to vary the final position of the tailgate when open. This helps to reduce the risk of damage, for example in an underground car park or garage with a low ceiling.Perfect combination of superior dynamics and outstanding comfort.A new type of vehicle and a new driving experience, the BMW X6 definitely offers the best of both worlds. In terms of driving dynamics, the first-ever Sports Activity Coupe offers new dimensions defined by a considerable enhancement of agility, unique stability in fast bends and safe traction on slippery surfaces. Powerful engines, BMW's intelligent xDrive all-wheel-drive technology, Dynamic Stability Control, optional Active Steering and Adaptive Drive, as well as Dynamic Performance Control featured for the first time on the BMW X6 even as standard equipment, set the foundation for superior driving dynamics at all times.Even with a moderate, reserved style of motoring, Dynamic Performance Control optimizes steering precision most considerably, enabling the BMW X6 to handle even difficult driving conditions through the outstanding quality of its drive and suspension technology.Driving dynamics with intelligent control: Integrated Chassis Management.The vehicle's drivetrain and suspension systems interact perfectly with BMW's Integrated Chassis Management. This high-performance electronic control ensures perfect harmony of drivetrain and suspension functions within fractions of a second, spelling out maximum driver control and supreme performance wherever you go and at all times.Even under a sudden change in driving conditions for example, on varying surfaces, in spontaneous steering maneuvers, when accelerating or applying the brake abruptly, ICM reacts with the utmost precision to the xDrive, DSC and Dynamic Performance Control actuators and to Active Steering when fitted as an option. In all cases, the nature and scope of such intervention is appropriately masterminded to ensure not just maximum driving stability, but also optimum dynamics.BMW's X Models already available today owe their outstanding agility largely to the supreme performance and qualities of ICM. Now the central control unit has an even greater and more progressive influence on driving dynamics in the new BMW X6, since it is also able to use the actuators serving for BMW's new Dynamic Performance Control. Depending on driving conditions and with fully variable management, the power of the engine is no longer split 'just' between the front and rear axle, but also - through Dynamic Performance Control - between the left and right rear wheel, feeding additional power to the most appropriate point where it can be conveyed best to the road.This drive technology quite unique in the market enhances the agility, steering precision and tracking stability of the car in corners as well as its traction on slippery surfaces, significantly improving driving dynamics in all cases and under all conditions.As a result, Dynamic Stability Control is only required to cut in by applying the brakes electively on the appropriate wheel or wheels when the vehicle really reaches the extreme limits to driving physics. The world's first Sports Activity Coupe thus offers the driver the truly fascinating experience of being able to handle even the most demanding driving situations with sporting style and dynamic performance never seen before.The drivetrain and suspension technology of the BMW X6 ensures the highest conceivable level of safety, precision and driving pleasure on all surfaces whether rough or smooth. The foundation of this purpose is provided by suspension technology quite unique in the segment of BMW X Models. The front axle, for example, is a double track control arm configuration applying the double joint principle for dynamic lateral acceleration, superior tracking stability and minimization of forces acting on the steering wheel. Appropriate front axle kinematics, in turn, ensure optimum front wheel camber on the road at all times, the BMW X6 thus maintains supreme grip and road-holding even under the most dynamic conditions.At the rear, the BMW X6 features BMW's patented Integral IV axle serving to harmonize superior comfort with equally superior dynamics. And now this lightweight construction has been specifically optimized for the Sports Activity Coupe in many respects, with the entire rear axle configuration being appropriately adjusted to the specific demands of this model, for supreme sportiness and performance.The wheel mounts, rear axle sub frame and four track arms efficiently take up the dynamic and drive forces flowing into the suspension, reducing any elastic distortion of the wheel mounts, while soft swinging mounts provide appropriate longitudinal suspension and optimize the roll quality of the wheels. Effectively separating the road surface from the drivetrain, finally, the rear axle helps to ensure first-class noise control and ride comfort.The BMW X6 comes as standard with 19-inch light-alloy wheels. Also featured as standard are run-flat safety tires, which enable continued driving even after a complete loss of pressure in the tires. Furthermore, the Tire Pressure Monitor system permanently monitors air pressure and warns the driver as soon as the air pressure in the tires drops more than 30 per cent below the ideal level.BMW xDrive: intelligent all-wheel drive for enhanced dynamics and optimum traction.Permanent all-wheel drive with electronically controlled, variable distribution of drive power between the front and rear axles gives all BMW X Models not only superior traction, but also enhanced driving dynamics. Indeed, BMW xDrive gains its superiority as an intelligent all-wheel-drive system by distributing drive power front to rear by way of an electronically controlled multiple-plate clutch according to driving conditions, in exactly the right dosage and to the axle with grip.In normal driving situations BMW xDrive distributes drive power in a 40 : 60 split front-to-rear, with sensors consistently measuring wheel slip. Hence, the system is able within a fraction of a second to vary the distribution of drive forces, with BMW xDrive-unlike conventional all-wheel-drive systems-anticipating the upcoming situation and not just responding once a wheel has started to spin. This serves to stabilize the vehicle even before the driver notices any need for action.On the new X6 with Dynamic Performance Control, handling and stability are enhanced to an even higher level with the ability to multiply torque to an individual rear wheel for yaw control. With the combination of xDrive and Dynamic Perforance Control, the X6 is able counteracting even the slightest trend to over- or under-steer right from the start at the earliest conceivable point with the positive effects on the driver's sense of driving dynamics.Unparalleled agility and tracking stability thanks to xDrive and Dynamic Performance Control.The positive effect of Dynamic Performance Control on the agility of the BMW X6 is clearly seen right from the start. In conventional everyday traffic, the vehicle steers into corners with significantly enhanced precision at any speeds.Dynamic Performance Control likewise enhances the handling and, indeed, the overall control of the BMW X6 in sudden steering maneuvers and at particularly high speeds in bends. If the vehicle begins to understeer or push to the outside of a corner BMW xDrive and Dynamic Performance Control will dynamically shift torque to the outside rear wheel in order to are able to counteract the understeer. On the other hand, if the vehicle threatens to over-steer, xDrive reduces the transmission of power to the rear wheels then the Dynamic Performance Control transfers torque and drive forces from the outer rear wheel and diverts these forces to the inner rear wheel.This intervention in the interest of greater stability is so quick and finely controlled that the driver will not even notice what is happening. What he will notice, however, is that the BMW X6 ensures exceptional steering precision and vehicle balance all the way to the extreme limit.Unique: Dynamic Performance Control enhances steering precision also when the driver takes his foot off the gas pedal.A further particular feature of Dynamic Performance Control is that engine power and torque are split variably between the rear wheels not only when the engine is 'pulling' the vehicle, but also in overrun. This is made possible by the addition of a planetary gear set and a multiple-plate clutch operated by an electric motor on both output sides of the rear differential. With this configuration Dynamic Performance Control is able to vary the distribution of drive power also when the driver takes his foot off the accelerator.The BMW X6 is the first vehicle in the world to offer such a stabilizing effect independent of engine load and drive power.Dynamic Performance Control also serves to optimize traction on a slippery surface. With its ability to vary the transmission of engine power specifically as required between the two rear wheels, Dynamic Performance Control serves to improve traction and pulling force whenever the vehicle is running on different surfaces from one side to the other, for instance, with asphalt on one side and a snowbound surface on the other. Any differences in the frictional coefficient between the wheels on the left and right (modal split) are offset by Dynamic Performance Control specifically sharing out drive forces on the rear axle.Easily viewable on the instrument cluster, the driver receives a clear message showing the interaction by Dynamic Performance Control. By simply pressing the lever on the steering column, the driver is informed of the current distribution of drive power via a bar diagram showing how much power is going to each of the four drive wheels at any given point in time.DSC intervening only when driving to the limit.The difference in drive forces between the two rear wheels provided by Dynamic Performance Control can be as high as 1327 lbs-ft (1800 Newton-meters). But even then, all the driver will feel when Dynamic Performance Control intervenes is a - significant - increase in agility, traction and driving stability. As a result of Dynamic Performance Control's intervention, the Dynamic Stability Control intervenes much less frequently than before. In practice, this means that the driver is able to use the full drive power and torque of the engine much longer than with a conventional system, DSC acting on individual wheels or reducing engine power only when the driver really pushes the car to the extreme limits of physical performance.In addition, DSC in the new BMW X6 offers a wide range of additional functions serving to promote safe and dynamic motoring including: ABS anti-lock brakes; Automatic Stability Control; Trailer Stability Control; Hill Descent Control; Dynamic Brake Control, automatically maximizing brake pressure when required in the interest of minimum stopping distances; Cornering Brake Control; and, finally, Active Cruise Control complete with its own brake application function.The Automatic Differential Brake serves as a transverse lock between the two wheels, and Fading Compensation increasing brake pressure as required under extremely high brake temperatures, helps to maintain the brake forces required even under extreme conditions. Regular Dry Braking, in turn, optimizes brake performance in wet conditions, while the Start-Off Assistant enables the driver to set off more smoothly and easily on an uphill gradient.The new BMW X6 features a parking brake operating both electromechanically and hydraulically, activated or released simply by pushing a button.Reflecting the high standard of driving dynamics offered by the BMW X6, DSC also comes with Dynamic Traction Control as a special function, raising the DSC response thresholds to a higher level, allowing a particularly sporting and active style of motoring, and enabling the driver to set off smoothly on snow or in loose sand with the drive wheels intentionally spinning slightly.Supported by a wide range of DSC functions, the high-performance brake system featured in the BMW X6 ensures excellent stopping power under all conditions. Inner-vented discs on all four wheels take up brake energy, newly developed lightweight brakes with floating aluminum calipers front and rear, guarantee extremely good resistance to fading and maximum brake comfort on the top-of-the-range BMW X6 xDrive50i.Active Steering for a particularly sporting and comfortable style of motoring.The BMW X6 is also available with Active Steering as an option. This very special system developed by BMW offers exactly the right steering ratio at all speeds, maintaining direct steering behavior up to a speed of about 55 mph, as required particularly for a sporting and active style of motoring. A further advantage in this case is that the driver only has to turn the steering wheel twice from lock to lock when parking. At higher speeds, on the other hand, Active Steering offers a more indirect transmission ratio in the interest of steady directional stability and, as a result, enhanced motoring comfort.On the BMW X6, Active Steering is combined with Servotronic, thus making an active contribution in stabilizing the car in the event of over-steer in bends or particularly demanding brake maneuvers. When applying the brakes on different surfaces left and right, for example, that is with a so-called modal split, Active Steering counter-steers discreetly but firmly to prevent the car from swerving out of control.Unique: Adaptive Drive with data transfer via FlexRay.Carefully harmonized interaction of the vehicle's anti-roll bars and dampers masterminded by Adaptive Drive is another unique feature in the segment of BMW X Models. Indeed, this combination of active body roll control and variable damper adjustment available as an option gives the new BMW X6 incomparably superior driving behavior.Using sensors in the vehicle, Adaptive Drive constantly monitors and calculates data on road speed, the steering angle, longitudinal and lateral acceleration, body and wheel velocity, as well as ride and damper position. Applying this information, the system acts directly on the anti-roll bar swivel motors and the electromagnetic valves in the dampers, varying body roll and the damping effect appropriately at all times and in all situations. Simply by pressing a button, the driver is able to choose either a sporting or a comfortable setting on Adaptive Drive.BMW Adaptive Drive uses high-speed FlexRay data transmission for fast and reliable coordination of data. This system, developed to production standard by a development consortium under the leadership of BMW offers a standard of data transfer capacity never seen before - and BMW is the first carmaker in the world to use FlexRay technology in a regular production car.Superior engine dynamics in both the xDrive35i and xDrive50i.Through its superior suspension technology, the BMW X6 is able to convert all the power of the engine safely and consistently into driving dynamics under virtually all conditions and on all kinds of surfaces. And the engines available in the first Sports Activity Coupe set standards themselves in terms of muscular performance, superior running smoothness, and outstanding efficiency in their respective class. Both the xDrive35i and xDrive50i feature Twin Turbo technology engines, representing the latest in state of the art engine technology-with the power range extending from 300 hp to 400 hp.The BMW X6 xDrive50i is powered by an all-new eight-cylinder, while the BMW X6 xDrive35i features the most powerful straight-six within the engine portfolio of Germany's leading premium car maker. The performance characteristics and efficiency for both of these engines benefits from the exclusive combination of Twin Turbo technology and High Precision Injection available only from BMW. The principle of combining two turbochargers and direct gasoline injection applied for the first time on the straight-six is now also to be admired on the new V8.A class of its own: The new eight-cylinder with Twin Turbo Technology.With Ultimate Driving Performance as the most important feature-this applies to BMW's X Models and to BMW's eight-cylinder engines-the BMW X6 is adding an incomparably dynamic variant to the line-up of BMW X Models, with the world's first Sports Activity Coupe boasting a particularly sporting and dynamic eight-cylinder.Displacing 4.4 liters, the new V8 engine with Twin Turbo technology and direct gasoline injection (High Precision Injection) develops maximum output of 400 hp throughout a broad range of engine speed from 5,500-6,400 rpm. Engine torque reaches its peak of 450 lb-ft throughout an unusually large speed range from 1,800-4,500 rpm. The spontaneous, intense and long-lasting thrust generated in this way is the result of Twin Turbo technology already featured on BMW's most powerful straight-six combined with High Precision Injection. The cooling effect of direct fuel injection also ensures a compression ratio quite unusual on a turbocharged engine, helping to give the engine an even higher level of all-round efficiency.The position of the turbochargers and catalytic converters in the V-section between the two rows of cylinders is likewise an innovation in technology allowing particularly compact engine dimensions and at the same time requiring new configuration of the intake and exhaust ducts. This means shorter intake and exhaust manifolds and larger cross-sections significantly reducing pressure losses on both the intake and exhaust side.The all-aluminum V8 engine developed for the BMW X6 offers all the qualities typical of an eight-cylinder in incomparably sporting style. In practice, this means a combination of superior torque at low engine speeds with an ongoing surge of power and performance up to the higher speed range.The BMW X6 xDrive50i accelerates from 0-60 mph in just 5.3 seconds and boasts ample power reserves for exceptional acceleration also at higher speeds. When equipped with the optional 20 inch wheels with performance tires, the top speed is a truly impressive 155 mph limited electronically by the engine control unit.Twin Turbo technology featured for the first time on an eight-cylinder gasoline engine.The power and performance characteristics of the new V8 result to a large extent from Twin Turbo technology, the use of two turbochargers for the first time on an eight-cylinder engine serving to boost both engine output and torque with maximum efficiency. Each of the two turbochargers supplies compressed air to four cylinders at a time, ensuring particular spontaneity and a direct reaction to the gas pedal.As with the straight-six featuring Twin Turbo technology, the 'turbo lag' typical of a turbocharged engine with conventional technology, that is the time until the turbocharger builds up its boost, is virtually eliminated through the combination of two small turbos and the direct injection calibration.A further advantage is that the engine revs up smoothly, maintaining its high torque consistently throughout an unusually broad range of engine speed. In its power and performance characteristics, therefore, the engine is comparable to a significantly larger normal-aspirated engine while offering the advantage of much lower weight and reduced package size.Not only are the dimensions and weight of the new V8 unusually modest, but the fuel consumption is also exceptionally low for an engine of this caliber. A significant factor contributing to the superior fuel economy is double-VANOS infinite camshaft management, a technology characteristic of BMW engines. Indeed, this technology is also one of the reasons why the V8 - over and above its superior fuel economy - develops exceptionally high torque from low engine speeds.High Precision Injection also plays a key role in the efficient use of fuel. This second generation of direct gasoline injection uses piezo-injectors positioned directly next to the spark plugs in the cylinder head and delivering fuel into the combustion chambers at a pressure of 2900 psi. The advantage is extremely precise dosage of fuel, with the further benefit of reduced emissions and improved engine acoustics. And last but not least, it almost goes without saying that the engine fulfils both the US ULEV II emissions standard as well as the EU5 requirements in Europe.The new V8 engine is the most efficient engine in its class. Combined with a number of further technologies developed in the overall context of BMW EfficientDynamics, the engine gives the BMW X6 xDrive50i fuel consumption and emission figures significantly better than other eight-cylinder vehicles competing with the BMW X Models.BMW's most powerful inline-six in the world's first Sports Activity Coupe.The second gasoline-powered version of the BMW X6 boasts the most powerful inline-six within BMW's engine portfolio: Maximum output of the engine featured in the BMW X6 xDrive35i is 300 hp from an engine capacity of 3.0 liters. This superior power is maintained consistently between 5,800 and 6,250 rpm, with maximum torque of 300 lb-ft provided all the way from 1,400-5,000 rpm. This gives the six-cylinder superior power and performance from an unusually early point on a gasoline engine, subsequently maintaining this high power throughout a broad range of engine speed.Like the new V8 engine, the engine in the BMW X6 xDrive35i offers the exclusive combination of Twin Turbo technology and High Precision Injection for incomparable power and performance, plus a standard of economy quite unique in comparison with the engine's dynamic driving potential.On the inline-six with Twin Turbo technology, two exhaust turbochargers each supply compressed air to three cylinders. The small mass inertia of the relatively compact turbochargers optimizes response to a significantly higher degree on this engine, building up charge pressure without the slightest delay from low engine speeds. The result is a rapid increase in power and torque further promoted by infinitely variable double-VANOS camshaft control.This characteristic of BMW's Twin Turbo gasoline engines is unique world-over and offers an exceptionally high standard of power and flexibility on the road. In practice, this allows the driver to use the superior torque of the engine right from the start when accelerating, with engine power then remaining consistent over a wide speed range.The exceptional dynamism of the engine is further enhanced by its high compression ratio, again an advantage made possible by High Precision Injection: With the fuel/air mixture being cooled as a result of direct injection, the compression ratio can be increased to a higher level than on a turbo-charged engine with intake manifold injection. Engine efficiency is improved accordingly, offering more power on less fuel.The level of power offered by the inline-six with Twin Turbo Technology and High Precision Injection is equal to a level that only a much larger eight-cylinder was able to provide in the past. But at the same time BMW's most powerful six-cylinder offers a much higher standard of fuel economy and, thanks to its all-aluminum crankcase, is much lighter.BMW EfficientDynamics: wide range of features serving to reduce fuel consumption and emissions - and all coming as standard.Offering a wide range of features serving to enhance efficiency on and around the engine, all versions of the new BMW X6 ensure a particularly good balance of power, performance and economy - and all these features come as standard.The all-round efficiency of the BMW X6 is further optimized by on-demand control and activation of the engine's ancillary units helping to significantly reduce the power required for the fuel and steering assistance pumps and thus again saving energy in the process.For example, the drive belt for the a/c compressor, comes with an independent clutch automatically disconnecting the compressor as soon as the driver switches off the air conditioning and thus reducing the drag forces generated by the compressor to a minimum.Further examples are the use of tires with reduced rolling resistance and the optimization of the car's aerodynamics. The cooling air flaps behind the BMW kidney grille and in the air intake, for instance, are controlled electronically, helping to reduce the air drag of the vehicle when closed and only being opened in response to greater demand for cooling.Automatic transmission designed for sports motoring.Power is transmitted on the BMW X6 in standard trim by six-speed sport automatic transmission with a particularly sporting gearshift now enhanced to an even higher level.The automatic transmission chooses the appropriate gear with incomparable spontaneity, precision and efficiency, benefiting both the comfort and driving dynamics of the BMW X6. The automatic transmission shifts gears either in response to the electronic gear selector lever or the gearshift paddles on the steering wheel.Intelligent lightweight technology for enhanced dynamics and solidity.Like the other models in the BMW X range, the BMW X6 boasts a particularly strong and sturdy body. To keep weight to a minimum despite this outstanding solidity, BMW's engineers developing the new model focused consistently from the start on intelligent lightweight construction. Both the choice of materials as well as the arrangement and geometry of the various support bars, rods and other support elements are based on an overall concept combining maximum crash safety with supreme agility on the road.The new BMW X6 not only includes front and side airbags as standard, but also curtain-type Head Protection System airbags at the side, protecting the occupants both front and rear from injury. Additional features include: three-point inertia-reel belts on each seat, with belt force limiters together with a belt tightener on the front seat; crash-activated headrests to prevent cervical spine injury in the event of a collision from behind, that come standard on the front seats.All restraint systems are masterminded by one central electronic safety 'brain' monitoring the type and severity of a collision and activating the most effective protection units in each case. The frontal airbags, in turn, come with a gas generator operating in two stages and thus activating the airbags with varying intensity, depending on the severity of an accident.In the event of an imminent rollover, the car's rollover sensor activates both the curtain airbags and the belt latch tensioners. Indeed, this integration of the system with DSC Dynamic Stability Control guarantees appropriate function of the overall safety system in good time whenever necessary. And to avoid accidents from behind the new BMW X6 comes with BMW's two-stage brake lights.The BMW X6. The first Sports Activity Coupe.The BMW X5 has already demonstrated most clearly that dynamic driving qualities are a decisive criterion also with a vehicle of this class and caliber. The BMW X3, in turn, has added outstanding agility as a further factor crucial to success in this segment. And now the BMW X6 focuses again on these priorities, raising them to an even higher level. As a result, the world's first Sports Activity Coupe from BMW once again sets the standard in a market segment characterized by particularly dynamic growth And at the same time the BMW X6, through its concept and drive technology, clearly proves and confirms the exceptional innovative power of Germany's premium carmaker.The new BMW X6 is expected to be in US BMW Centers in the second quarter of 2008. Options, pricing and precise launch timing details will be communicated as the launch window nears.

2007 Maybach Landaulet Study Concept

Source - Maybach
Maybach shows one of the world's most exclusive luxury cars
  • Majestic open-air experience with the ultimate in luxury and comfort
  • Folding roof for pampered rear-seat passengers
  • Appointments in the rear include white leather, piano lacquer and exquisite black granite Stuttgart– With this study of an open-top landaulet, Maybach has re-enlivened the great art of building majestic automobiles. True to the tradition of exclusive landaulets, the roof of this sparkling white one-off study can be opened fully at the rear, while the chauffeur's compartment remains completely enclosed. The passengers are then able to enjoy the clear, blue sky above. Seated in opulent armchairs upholstered in white leather, they are treated to a majestic open-air experience currently unrivalled by any other automobile in an environment of the utmost luxury and exquisite style. Romance close to the heart of nature is harmoniously combined with the ultimate in comfort and technological sophistication. With this unique study, Maybach is once again demonstrating its expertise in building the world's most exclusive luxury cars.Large folding roof for passengers in the rearIn technical terms the Landaulet study is based on the Maybach 62 S – which can claim to be the world's most powerful series-produced chauffeured saloon. Maybach technicians have removed the rear roof module in order to afford passengers an unobstructed view of the sky above.
    The side walls remain, and have merely been invisibly reinforced with an integral tubular steel structure. As these measures have not altered the silhouette of the luxury saloon, the generously dimensioned doors and the complete interior with its reclining seats remain unchanged. When closed the black soft-top of the Landaulet rests on the frame formed by the roof bows, and is wind and weather-proof. When requested by the passengers, the chauffeur operates a switch in the centre console. The roof then opens electro-hydraulically and is gently deposited on the parcel shelf in the rear, together with its integral rear window of single-layer safety glass. Opening and closing the roof takes 16 seconds. The chauffeur is able to enclose the folded roof with a fitted leather cover, which both conceals the roof mechanism from view and completes the overall picture of outstanding elegance. White paintwork and wheels This impression is accentuated by the shining white paintwork of the study, an exclusive finish named antigua white. Visual highlights are provided by 20-inch wheels specially designed for the Landaulet study. These are also painted in white with high-sheen spokes, and are accompanied by white indicators in the front and rear light clusters in dark red.Black for the chauffeur, white for the passengers In addition, the already luxurious driver's compartment of the successful Maybach 62 S has been enhanced in a number of important respects. All the interior trim is now surfaced in black piano lacquer, and for the extensive leather appointments Maybach has used particularly exclusive, glossy stromboli black leather. In contrast Maybach has fitted the passenger compartment almost completely in exquisite seychelleswhite leather. The footwell and roof liner of this high-end luxury landaulet are also in white – the floor is carpeted in white velour and the roof lined with white fabric. A dramatic contrast is provided by inserts and decorative trim in glossy, black piano lacquer or exclusive black granite with numerous gold inclusions.Generous spaciousness and first-class comfortOutstanding comfort is assured by the generous spaciousness of the rear, which the Landaulet study has adopted unchanged from the Maybach 62. Passengers are welcomed into the interior by two large, single seats. These elegant seats also allow even very tall passengers to enjoy a reclining position which travellers normally only encounter in the first-class armchairs of modern passenger jets. The study is designed as a chauffeured vehicle and features a partition. The upper section of the partition is a glass panel which the passengers can render opaque at the touch of a button, thanks to a liquid crystal membrane embedded in the glass. Two ultra-modern automatic climate control systems, whose parameters have been adapted to the Landaulet study, ensure that open-air travel remains a pleasure even under adverse climatic conditions.State-of-the-art entertainment and communications As in the Maybach 62 S, the rear console is the centrepiece for entertainment, communications and travelling pleasure. This is where Maybach engineers have grouped everything relating to the entertainment and pleasure of the rear-seat passengers: a DVD-player, six CD-changer, a cooler compartment with its own electric compressor and an intelligent system which holds glasses, goblets and champagne bottles safely in position. Engine and suspensionThe Maybach Landaulet study is powered by the uprated V12 engine which Maybach engineers have developed further for the Maybach 57 S and Maybach 62 S together with the specialists at Mercedes-AMG. Thanks to twin turbochargers and water intercooling, the V12 develops a maximum output of 450 kW/612 hp from a displacement of 5980 cubic centimetres. This is continuously available between 4800 and 5100 rpm, and the engine also delivers an impressive maximum torque of 1000 newton metres between 2000 and 4000 rpm. The electronically controlled air suspension AIRMATIC DC (Dual Control) and the Adaptive Damping System (ADS II) endow the Landaulet with outstanding levels of ride comfort, at the same time demonstrating that even a prestigious vehicle such as this can exhibit extraordinary agility and dynamic performance. In addition to large, internally ventilated brake discs – with twin callipers at the front – both the study and the Maybach 62 S are equipped with two electro-hydraulic Sensotronic Brake Control (SBC™) braking systems working in tandem. Together with ESP®, ASR, ABS and Brake Assist, this provides the Landaulet study with the very latest in effective, high-tech handling control systems. Innovative technology from the sister-brand Mercedes-BenzLike all Maybach saloons, the Landaulet also benefits from the unrivalled experience of the sister-brand Mercedes-Benz in the development and production of high-quality cars in the luxury segment. Important innovations from Mercedes-Benz, successfully developed further for the Maybach saloons, are standard equipment in every Maybach and are of course also on board the Landaulet study – examples include the electronically controlled air suspension AIRMATIC DC (Dual Control), LINGUATRONIC voice control and the control and display system COMAND APS.

    2007 Aston Martin V12 Vantage RS

    At the official opening of Aston Martin's first ever dedicated design center in Gaydon, Warwickshire, on Tuesday 11 December, Dr Ulrich Bez, Chief Executive Officer, thrilled an audience of more than seven hundred VIP guests with a surprise unveiling of a stunning new 600bhp performance concept car; the V12 Vantage RS.The V12 Vantage RS concept is based on Aston Martin's critically acclaimed V8 Vantage coupe, but the company's design and engineering team have fully exploited the design flexibility of their unique VH architecture and the motor sport development of their 6.0 litre V12 engine to create a dramatic and production feasible concept car focussed on extreme performance and dynamics. In a speech to the assembled guests, Ulrich Bez said: 'Over the last five years, we have established a reputation for presenting fully functional, feasible concept cars, and the V12 Vantage RS is no exception. We will listen with interest to feedback on this concept and, as ever, if there is sufficient demand then we will seriously consider a low volume production run in the near future with a price that will reflect the exclusivity of the car.'With our dedicated production facilities, our own engine plant, our own unique vehicle architecture and now a dedicated design studio, we have the ideal framework to bring new models such as this to market and to further establish Aston Martin as the ultimate independent luxury sports car company.'Although the 600bhp power output of the V12 Vantage RS concept will be the focus of attention, just as significant is the level of weight reduction achieved by Aston Martin's engineering team. With a kerb weight of less than 1600kg, the RS concept underlines Aston Martin's continued commitment to intelligent use of materials and weight reduction as a means of achieving improved efficiency and performance. In common with the recently launched DBS, the bonnet and trunk lid are moulded in carbon fibre and the concept also adopts motor sport-inspired carbon ceramic brake discs.The subtly aggressive exterior appearance is driven by function. The dramatic bonnet louvres extract air from the fully ducted cooling pack and the trunk lid features a deployable spoiler that rises automatically at high speeds to increase rear down force. The front bumper features cooling ducts for the carbon ceramic brakes and a carbon fibre splitter to balance down force.Director of Design, Marek Reichman, commented: 'Much of Aston Martin's recent success has come from the ability of our designers and engineers to work hand-in-hand to optimise form and function. Our new dedicated design centre will take this process to a new level and I am delighted that the V12 Vantage RS is the first car to stand on the turntable in the studio.'The 600bhp 6.0 litre engine featured in the V12 Vantage RS concept has benefited directly from the race development of this acclaimed power unit. It features a dry sump lubrication system, tuned length exhaust manifolds, forged pistons and steel con-rods, revised lift and duration camshafts and modified cylinder heads. Peak power is achieved at 6250rpm and peak torque of 690Nm is at 5000rpm.With a power-to-weight ratio of over 375bhp per ton, the V12 Vantage RS concept is the fastest accelerating road car ever built by the company, capable of reaching 62mph (100km/h) from rest in 4.0 seconds and 100mph (160km/h) in just 8.5 seconds.The unveiling of the Aston Martin V12 Vantage RS concept concludes a remarkable year of new product announcements for the British manufacturer. In the last twelve months the company has launched two of the most eagerly anticipated sports cars of the year – the DBS and Vantage Roadster – and announced details of the DB9 LM and V8 Vantage N400 special editions which celebrate the company's racing successes at Le Mans and the N?rburgring. All of these models now join the award-winning V8 Vantage, DB9 and DB9 Volante models in production at the company's Gaydon headquarters.

    10 World’s Fastest Cars

    10. Lamborghini Gallardo 13.65 secs

    In the 0-100-0 mph race Lamborghini Gallardo is faster than its bigger and stronger brother by three hundredths of a second, primarily because of its lower weight. Gallardo is powered by 5.0 liter V10 engine which provides 520 hp, which scorches it from 0 to 60 mph in 4 seconds.

    9. Porsche 911 Turbo 12.5 secs

    Thanks to its sophisticated integral drive which limits wheel sliding, new ‘turbo’ successfully transfers its 480 hp to the ground and proves that power is not the most important.

    8. Caterham CSR260 11.95 secs

    British Caterham has always been known as one of the fastest cars in the world (0-60 mph in 3 seconds). It is not surprising since its mass and power ratio wouldn't put super sports motorcycle to shame. CSR 260 is powered by a 2.3 liter engine which provides 250 hp and weighs 555 kilograms which is approximately 0.5 hp per kilogram.

    7. Pagani Zonda 11.8 secs

    An Italian with a German heart is one of the most extravagant supercars of a mass production. Its Mercedes AMG 7.3 liter V12 engine provides 555 hp, sufficient to accelerate from standing start to 60 mph in 3.4 seconds and develop maximum speed of 220 mph.

    6. Porshe Carrera GT 11.6 secs

    The strongest mass production Porsche of all times with the centrally positioned 5.7 liter V10 engine is one of the technologically most advanced GT cars ever made. The car is almost completely made out of carbon fibers and composite materials, and after 1,270 cars were soled recently it became one of the most successful super cars of all times.

    5. McLaren F1 LM 11.5 secs

    A car created for only one reason – to be the fastest one. The uncompromising creation process provided it such title for ten years during which it remained unbeatable by the competition. Its BMW gold-plated V12 engine (for better cooling) provides 627 horsepower. The maximum measured speed is 240 mph.

    4. Ferrari Enzo 10.9 secs

    The fastest Ferrari of all times was named after the founder of a legendary Italian manufacturer. Until recently the fastest car in the world was first beaten by the legendary McLaren F1 in all categories from acceleration to maximum speed. Only 399 Ferrari Enzos were produced.

    3. Ariel Atom 10.88 secs

    For the price of one Carrera GT you can buy a dozen of this auto brand. Atom is manufactured by a small British company from Somerset with only about ten employees. Its Honda engine, taken over from Civic Type-R, is supplemented by mechanical supercharger which provides 300 hp. Having in mind that Atom weighs only 456 kilograms, its acceleration from 0 to 60 mph in 2.9 seconds is not surprising.

    2. Bugatti Veyron 16.4 9.9 secs

    A car which redefined the terms used to describe supercars. While its competitors have narrow, noisy and too heated interiors, Veyron provides comfort and enjoyment to two passengers, characteristic of the most luxurious limousines. Veyron weighs almost two tons, which makes it the heaviest car on the 10 fastest cars list. Still, its weight does not prevent it from giving 0-100-0 mph a time of less than 10 seconds with the maximum speed of 253 mph, which is why until recently it was the fastest car in the world. It is all because of its sophisticated integral drive and unique W16 engine which provides 1001 horsepower

    1. Ultima GTR 9.4 secs

    Less than a two months ago a small British car company represented its version of ultimate race car for the road drive based on Chevrolet V8 engine which provides 730 hp and entered the Guinness Book of World Records beating the Veyron’s time by five hundredths of a second. 720 GTR scorches from 0 to 60 mph in 2.6 seconds, from 0 to 100 mph in 5.3 seconds, and brakes to 0 in 3.6 seconds (not including drivers reaction time). No traction control devices or ABS braking aids were used.

    Lamborghini Reventon


    Lamborghini Reventon Reventon , it's based on the Murcielago LP640, and it'll cost a breezy one-million euros.

    Lamborghini Reventon
    Base Price 1,400,000 $
    Power 650 BHP
    Zero to 60 mph 3.3 s
    Zero to 100 mph N/A
    Top speed 211 mph / 340 km/h


    Lamborghini Reventon The Reventon, powered by a 650-horsepower 6.5L V-12 and wrapped in CFC carbon fiber composite, has harsh, angular lines down to the spiky arrow nose. Although it is based on the extraordinarily successful Murciélago LP640, the exterior design of the Reventón is completely new. Just like the base model, the exterior is made of CFC, a composite carbon fibre material, which is as stable as it is light. The exterior components are glued and fixed to the body comprised of CFC and steel. The technology found in the Murcielago LP640 has not been modified. The engine in the LP640 forwards is the classic twelve-cylinder engine with 6.5 liter displacement. Only for this car, Lamborghini guarantees, an astounding 650 bhp at 8,000 revolutions per minute (rpm). The huge torque, equal to maximum 487 lb-ft, ensures a powerful switch from any number of revolutions: even the slightest pressure on the accelerator is spontaneously transformed into thrust.

    New Dodge Challenger

    2009 Dodge Challenger concept car is powered by a 425 horsepower 6.1 liter V8 connected to a pistol grip manual transmission, but when the car goes into production in 2009 with a HEMI V8 nestled in the engine bay. The production version of the 2009 Dodge Challenger will make an appearance at the Chicago Motor Show next February, with production starting in 2008. Chrysler's Brampton, Ontario assembly plant has been earmarked for Challenger production.

    Dodge Challenger The retro-style coupé will be sold only in North America – and in strictly limited numbers. The decision overturns plans drawn up by previous owner Chrysler to export the Challenger to the UK. According to sources, Chrysler is trying to decide on which strategy to follow: a high-price, low-volume run, or a high-volume, lower-price run. Also in flux is the question of engines - restricting to just the Hemi, or allowing both the Hemi and at least one V6. Chrysler announced a manual transmission will be available along with an automatic , each having five speeds; an SRT-8 version will have the 6.1 Hemi while the stock Challenger will have the 5.7 Hemi. LY is the platform code for the second-generation LX cars , this basic platfom, which like the LX uses a Mercedes-style suspension with Chrysler engineering for better driving dynamics, higher reliability, and strong cost savings, will be used on the Mercedes E, CLS, and R classes, starting in, depending on the model, 2010 to 2012 .

    252mph, 1001PS, 16 cylinders, four turbos, 8.0-litres... the Veyron's numbers are staggering. It can hit 60mph in 2.5 seconds thanks to four-wheel-drive traction, shoots to 125mph in 7.3 seconds and reaches 200mph in less than 20. The Veyron 16.4 is the most powerful, most expensive, and fastest street-legal production car in the world , with a proven top speed of over 400 km/h (407 km/h or 253 mph top speed).

    The obvious question: Why would anyone build such a car? Surely no one sees doing 250 mph on the highway. There can be no commercial logic behind such a crazy machine, even with the Veyron's price tag of one million euros (at the current exchange rate, that's $1.2 million). Not even as a "halo model" -- a reputation booster -- for the VW group that builds it does the Veyron make sense. No Bugatti owner wants it known he's driving a Volkswagen.

    Bugatti Veyron Data
    Base Price 1,000,000 euros (1,300,000 USD)
    Power 1000 hp
    Zero to 60 mph 2.5 s
    Zero to 100 mph 6 s
    Top speed 253 mph (407 km/h)


    Development of the Veyron began with the 1999 EB 18/4 "Veyron" concept car . Introduced at the Tokyo Motor Show , it was similar in design and appearance to the final Veyron production car. One major difference was the EB 18/4's use of a W18 engine with three banks of six cylinders. The Veyron was designed by Hartmut Warkuss of Volkswagen rather than Giorgetto Giugiaro of ItalDesign who had handled the three prior Bugatti concepts.

    Development continued throughout 2001 and the EB 16/4 Veyron was promoted to "advanced concept" status. In late 2001 Bugatti announced that the car, officially called the Bugatti Veyron 16.4 , would go into production in 2003. The car experienced significant problems, however. High-speed stability was difficult, with one prototype destroyed in a crash and another spun out during a press demonstration at the Monterey Historics event in Mazda Raceway at Laguna Seca . Production of the Veyron was delayed indefinitely.

    After the release of the car, it has become known that while each Veyron is being sold for £840,000, the production costs of the car are approximately £5 million per vehicle. As Bugatti, and therefore Volkswagen, are making such a huge loss, it has been likened by influential journalist Jeremy Clarkson to Concorde ; both are largely impractical experiments in technology and ground-breaking performance created just to prove that it could be done. A car the like of the Bugatti Veyron may not be seen in production again for some time to come, if at all.


    The Veyron features a W16 engine —16 cylinders in 4 banks of 4 cylinders, or the equivalent of two narrow-angle V8 engines mated in a vee configuration. Each cylinder has 4 valves , for a total of 64, but the narrow V8 configuration allows two camshafts to drive two banks of cylinders so only 4 camshafts are needed. The engine is fed by four turbochargers , and it displaces 8.0 L (7,993 cm³/488 in³) with a square 86 by 86 mm bore and stroke.

    The Veyron's 16-cylinder engine is based on the innovative "W" design introduced in the 2003 Volkswagen Passat. The Veyron's version features two 90-degree V8s offset by 15 degrees. The offset allows each cylinder to be placed close to its neighbor, which reduces the total size of the massive 8.0-liter engine. A Formula 1?style dry-sump lubrication system keeps the engine moving smoothly. It's easier to spin many small turbochargers than one or two large ones, so Bugatti employs four turbos to reduce boost lag. The strategy works: The engine creates 922 lb.-ft. of torque at only 2,200 rpm.

    Putting this power to the ground is a dual-clutch DSG computer-controlled manual transmission with 7 gear ratios via shifter paddles behind the steering wheel. Or it can be driven by full automatic transmission. The Veyron also features full-time all wheel drive , necessary given the output of the engine. It uses special Michelin PAX System run-flat tires, which had to be designed specifically for the Veyron, and which are capable of running at 402 km/h (253 mph).

    The car's wheelbase is 2700 mm (106.3 in). Overall length is 4466 mm (175.8 in). It measures 1998 mm (78.7 in) wide and 1206 mm (47.5 in) tall. Curb weight is expected to reach 4300 lb (1950 kg) with a power to weight ratio of 513.3 hp per ton (metric) or 4.36 lb/hp (SAE).The Bugatti Veyron has a total of 10 radiators .

    Redesigned for the 2008 model year, the Cadillac CTS keeps everything that was good about the first-generation model and seems to improve everything that wasn't — and not just a little. More refined exterior styling, greatly improved interior design and quality, more power and optional all-wheel drive mean the CTS is poised to give the Infiniti G35 and other entry-level sport sedans some tough competition.

    Introduced in 2002, the current CTS generation has love-it-or-leave-it styling. Fortunately for Cadillac, there were as many love-its as there were leave-its — or at least enough to make the model a success. Still, some aspects of the car were odd and looked unfinished, and Cadillac has been tweaking the design ever since. The new model is a much more unified design that will be hated by some but loved by even more than the original model was.

    One controversial element is the tall grille, which plunges down low on the bumper — similar to new designs from the likes of Audi and Volkswagen. If you don't like those, you probably won't like this. The CTS hasn't given up the edges, but it now has more curves in the right places. The wheels are 2 inches farther apart, which together with the lowered front bumper gives the car a ground-hugging, sturdy look. The bizarre tail has been replaced by a more sensible shape, with a lip spoiler that incorporates the center brake light.

    The CTS is another in a string of new cars to incorporate small vents high on the front fenders, right in front of the doors, but Cadillac gets extra credit because those on the CTS are functional: They're an outlet for cooling air that's routed past the front disc brakes from inlets in the wheel wells.

    Seventeen-inch wheels are standard and 18s are optional.

    The interior is perhaps the CTS' greatest improvement — which says something about both the original and the new version. In the previous generation, someone's idea of a high-tech look was to base the center control panel's design on a tower PC, complete with a plasticky finish, gridlike vents and a CD player slot that emulated a disk drive. (You remember those, right?) When you think luxury, do you really think of something you hide under your desk?

    The new interior design is more conventional, yet modern, with vastly improved materials that look and feel high in quality. The "satin metallic" center control panel bezel is borderline, but real wood trim can be substituted as an option.

    The heated and ventilated seats use what Cadillac calls thin-seat technology to provide the same comfort in a chair that's thin enough to increase legroom.

    Under the Hood
    The big news is that a new version of the 3.6-liter V-6 engine generates 300 horsepower and 270 pounds-feet of torque, partly through the use of direct fuel injection. The original 258-hp, 3.6-liter engine stays on as the middle of three engines offered. The base power plant in rear-wheel-drive versions is a 210-hp, 2.8-liter four-cylinder, also a carryover from the current model.

    The standard manual transmission is a six speed, as is the optional automatic, which also provides a manual-shift mode. Steering-wheel shift paddles aren't offered. Also new is optional all-wheel drive, which mates with either V-6, but only with the automatic transmission. This helps the CTS join the ranks of the Infiniti G35 and BMW 3 Series models with an "x" in their model name, and is sure to increase sales in snowy regions.

    The CTS offers two suspensions: standard and performance. The latter provides a firmer ride, (claimed) improved roadholding, larger brake discs, two-piston rear calipers where the regular suspension has one, and 18-inch wheels with lower-profile summer or all-season performance tires.

    Some of the CTS' notable standard and optional features include adaptive headlights that swivel in the direction of a turn, remote start, Easy Key keyless access and ignition and a 5.1-channel digital surround-sound stereo.

    In addition to an analog auxiliary input jack for any MP3 player, the CTS lets you attach a player that uses a USB cord and control it through the stereo and steering-wheel controls. The playlist appears on the optional navigation screen. This 8-inch touch-screen telescopes out of the top of the dashboard. For parking assistance, the CTS offers a sonar system that beeps with increasing frequency as the rear bumper approaches an object.

    Standard safety equipment includes four-wheel-disc antilock brakes and an electronic stability system with traction control. In addition to the required frontal pair, there are side-impact airbags for the front occupants and side curtains that protect all occupants. The steering wheel tilts and telescopes.
