Born back in happier times before Chrysler's partnership with Mercedes-Benz fizzled, the ME Four-Twelve concept car proved what could be achieved with their combined gene pool of talent. Using an AMG-developed mid-mounted V-12 engine and four turbos (hence the name), the ME Four-Twelve was supposedly good for 248 mph and goes 0 to 60 in 2.9 seconds. There was even talk of putting the ME Four Twelve into production, with Chrysler going so far as to crash test one, but those dreams died when the wheels came off the Daimler-Chrysler bus.
