Introduction

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.

Technology

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 .

Introduction

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.

History

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.

Technology

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 .
