WOW 0-60 mph in 2.9 seconds, 0-100 mph in 6.2 seconds, and it will blister through the quarter mile in 10.6 seconds at 135 mph. The estimated top speed of the ME Four-Twelve is 248 mph (400 km/h). http://www.allpar.com/cars/me412.html
Yah it wasn't ever really going to production, such a shame. Chrysler could have made it, but it would have walked all over the $650,000 Mercedes SLR, so they couldn't allow it.
