BMW E92 M3 RACE CAR.

Eat your heart out. In 2009, Bobby Rahal and David Letterman are teaming up to bring the fourth-generation M3 to the racing series. To properly battle the best competition in ALMS, BMW bumps the power quotient of its high-revving 4.0L V8 from 414 to 485 ponies, but brute force is just one facet of the M3's attack plan. The already outstanding chassis of the M3 has been further enhanced for the track, and weight has been reduced to make the deadly M even more nimble.
