This vehicle, hands down, is one of the best-looking products Chrysler has ever put on the road (or at least on a show stand). Built on a carbon-fiber and aluminum honeycomb chassis tub, and wielding a 6.0-liter Mercedes V12, the ME Four-Twelve concept was reportedly good for a 0-60 mile-per-hour sprint (96 kilometers per hour) of just 2.9 seconds, and a top speed of 248 mph (399 kmh). It’s the supercar that Chrysler should have built, but never did, and probably never will.
