BMW recently presented the racing version of the new BMW M3 at the Chicago Auto Show. Powered by a 485 bhp eight cylinder engine, this impressive race car has been designed to compete in the American Le Mans Series (ALMS) beginning in 2009. The car is based on the fourth generation of the BMW M3, the highperformance sports car produced by BMW M GmbH
The race version of the BMW M3 is clearly aimed at the top echelon of motorsport. As such, it is no surprise to discover that in the course of its development, begun in mid-2007, numerous Formula One techniques were applied. These include computational fluid dynamics (CFD) and wind tunnel analyses, both of which have ensured the best possible aerodynamic package for the BMW M3.
