Four turbochargers on a Twelve-cylinder engine = light speed

The ME Four-Twelve was a concept car DaimlerChrysler produced under the Chrysler brand in 2004, impressive also for taking less than one year for design and development. The peculiar name is rooted in the Mid-Engine with Four turbochargers on a Twelve-cylinder engine. The car bears more than a passing resemblance to the Ford GT90 in both appearance and mechanics. While the declared top speed was faster than the McLaren F1 (400 km/h or 249 MPH), the car was never actually produced, probably due to tensions with Mercedes-Benz, so it couldn't receive the title of fastest production car. That title now rests with the Bugatti Veyron.
Chrysler initially stated that the ME Four-Twelve was a prototype intended to lead to production. They later put a temporary stop to the project after several protests from the SLR division of Mercedes-Benz. However, as of fall of 2005, Chrysler reportedly announced that the project was again "under active consideration" for continued development. Interestingly enough, the car did in fact pass government crash test and safety ratings, despite the fact that it was never actually produced.
