    BMW M3 (E92) American Le Mans Series (ALMS) 2009

    BMW RETURNS TO ALMS WITH THE LATEST GENERATION BMW M3
    02/06/2008

    BMW of North America to partner with Rahal Letterman Racing for 2009 season

    Chicago, IL/Woodcliff Lake, NJ - February 6, 2008... BMW 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 high-performance sports car produced by BMW M GmbH.

    BMW Motorsport Director Mario Theissen says: "With the sporting genes of the production BMW M3 being clearly evident, developing a racing version of the car was the next logical step. The fact that the road-going vehicle is fitted with a V8 engine as standard provided us with an ideal base. However, the BMW M3 is more than a race car, it has achieved legendary status amongst race fans across the globe. I am convinced that this unique story of the BMW M3 racing cars will now be expanded upon by the addition of further chapters."

    BMW's 2009 entry into the American Le Mans Series will be driven by a partnership between BMW of North America, LLC and Rahal Letterman Racing, co-owned by US motorsport legend Bobby Rahal.

    "We are very pleased to be returning to the American Le Mans Series with our latest generation BMW M3," states Tom Purves, Chairman and CEO, BMW of North America. "Sports car racing has been part of BMW of North America's history practically from day one. Just two weeks after the company was incorporated in March 1975, a BMW CSL won the Twelve Hours of Sebring. We are confident that the fourth generation M3 will continue the legacy of its two predecessors which combined to win six manufacturer's championships over nine seasons in US sports car racing. As it has been in the past we believe the ALMS is the ideal venue to showcase the potential of the newest BMW M3."

    Echoing that sentiment Bobby Rahal adds, "BMW has an illustrious racing heritage. Rahal Letterman Racing is eagerly anticipating, not only becoming part of that heritage, but helping to enhance it. Our dedication to this project will be without equal and we look forward to racing at the front of the grid with BMW in the years to come."

    Well i like the front, i think it looks much more purposeful than the E46 GTR, but the rear?? what the hell is going on with those vents at the back?? Still cant argue with the fact that, on paper, it looks like it will be highly competitive as the E46 was.

    The hot air from the brakes needs to escape somewhere, but the main reason for those vents will be to extract the high pressure air from the wheel arch, which slows the flow running down the side of the car. I find it interesting that there is no apparent diffuser, I suspect that white flat floor at the rear is either missing strakes, or a dummy until the car hits the grid.

    Damn sexy looking car though!! Wonder if they'll do a GTR Strassenversion (spelling?) like they did with the E46.

    I didn't think the GTR was competitive at all.

    Probably not since the standard car already has the V8.

    It was so competitive they banned it.

    In what series? They got eaten by GT3s in the ALMS.

    EDIT:

    Just did some investigating. They were banned with good reason - the early GTRs were in violation of the spirit of the rules with V8s.l

    That being said, the works BMW team managed to beat privateer Porsches even when they ran with I6s in 2001.

    Have they banned rear diffuser in ALMS for 2009? Because I doubt this design is better than one with rear diffuser like the DBR9
    Life is too short to stay, race!

    Gora Euskadi! Visca Catalunya!

    Different class, DBR9s are for GT1 class, with the C6.R Vette and such, whereas this is for GT2, with the GT3 RSRs and F430 GT....

    F430 GT, GT3 RSR don't have a "real" rear diffuser either, just an up swept engine bottom cover that's kinda like what the BMW has....

    Different class
    Thank you, I thought all production based cars competed in the same class...So I would like to see a GT1 class M3, it would be interesting
