The BMW M3 ALMS, short for American Le Mans Series, was unveiled for the first time at the Chicago Auto Show in February and we provided live coverage from that event.
Bobby Rahal and David Letterman teamed up to bring the fourth-generation M3 to the racing series. The new BMW M3 ALMS is powered by 4.0L V8, 485 horse power. The chassis of the M3 has been enhanced for the track, and weight has been reduced to make the fast M3 even faster.
