Without doubt, the race-prepped 2008 M3 at BMW’s stand was one of the sexiest cars around at the McCormick place. While the Bavarian carmaker has yet to release any pics, we managed to squeeze between the crowds and take a few pictures of the M3 to share with you. Powered by a modified version of the road-going M3’s 4.0-liter V8 engine that develops 485 HP, this car has been designed to compete in the American Le Mans Series (ALMS) beginning in 2009. –Details and pics after the jump (Pictures: rezza foournito)
BMW RETURNS TO ALMS WITH THE LATEST GENERATION BMW M3
BMW of North America to partner with Rahal Letterman Racing for 2009 season
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
"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
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."
Martin Birkmann, Motorsports Manager, BMW of North America, adds: "We are very excited to announce our return to the American Le Mans Series with the 4th generation M3 at the same time as the road car hits the BMW showrooms. We are also excited about our partnership with Rahal Letterman Racing. The ALMS offers racing where we can compete against the finest and most renowned automotive brands from Europe and the
The BMW M3 Race Version: Sportiness personified.
In the course of developing the race version of the BMW M3, BMW's engineers were faced with an ambitious task: to improve upon the sportiness of an already sporting car. A better base would, though, be difficult to find. In standard form the vehicle delivers powerful dynamics and sporting aesthetics. Thanks to an eight cylinder engine producing 414 bhp, BMW's customers are provided with a unique driving experience.

In order to enable the BMW M3 to make full use of this performance on the race circuit, the experts in
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.
Intelligent control systems have been incorporated throughout the BMW M3. The POWER400 control unit actuates all the accessories fitted to the car, such as lights, wipers, etc., via two bus systems. Traditional relays and fuses are thus eliminated, ensuring considerable weight saving, improved reliability and ease of application. The functions of the BMW P65 engine are managed by an ECU 408 electronic control unit, developed in-house by BMW Motorsport. The software and applications, too, have been developed by the experts in
An intensive test program, during which the performance of the race car will be honed by BMW Motorsport, looms for the BMW M3 over the coming months. Development drivers will be BMW works drivers Andy Priaulx (GBR), Jörg Müller (GER) and Augusto Farfus (BRA), currently racing in the FIA World Touring Car Championship (WTCC). The aim is, after all, for the BMW M3 to be an immediate front-runner upon its comeback to the American Le Mans Series.
BMW Racing in North America
BMW's return to race track coincides with the fourth generation M3's entry into North American showrooms, a pattern familiar to those eager to follow the newest chapter in BMW's storied racing history.
After the CSL's, the 70's ended with the 320 Turbo. Known affectionately as the "Flying Brick" the flame-throwing coupes delighted sports car racing fans with their signature exhaust fire. The program also added reams of data to BMW's turbocharging technology, information that would help a BMW-powered Brabham win the 1983 Formula One World Championship.
In the late 1980's BMW of North America entered IMSA's top prototype category with the BMW GTP. The program netted only one win, but added incalculable experience to the men and women responsible for racing here in the
When the checkered flag fell on the last race of the 2006 season, BMW of North America wrote the final page of the most successful chapter to date of its 31-year motorsport story. From 1995 through 2006, BMW of North America's M3 racing program drove to 53 wins in 118 races entered, adding 14 championship trophies to corporate display cases and a shine on the Roundel like never before.
Return to familiar territory.
BMW can look back on numerous successes and titles in the ALMS. The BMW V12 LMR prototype won the inaugural ALMS race in 1999 at the Twelve Hours of Sebring. In 1999 and 2000 the BMW V12 LMR went on to score six victories. For 2001 BMW switched to the GT Class, winning everything in sight with the BMW M3 GTR, which was developed specifically for the ALMS: BMW works driver Jörg Müller claimed the drivers' championship, Team BMW Motorsport took the team title and BMW won the manufacturers' championship in the company's most important market.
BMW in the American Le Mans Series.
The American Le Mans Series is far from virgin territory for BMW. During both 1999, the series' inaugural season, and the following year, the company celebrated major successes in
In 2001 BMW deployed a new car. For the third ALMS season a switch was made from the Prototype category to the GT class using the BMW M3 GTR, a totally new development powered by an eight cylinder engine delivering 450 bhp. Two operations, Team BMW Motorsport from
The debut season of the BMW M3 GTR rapidly became a success story: BMW drivers mounted the top step of the podium seven times, with six pole positions falling their way. BMW works driver Jörg Müller captured the drivers' title, Team BMW Motorsport took team honors, and BMW the manufacturers' championship. After a development program totalling less than six months BMW was able to lay claim to no less than three championships with the BMW M3 GTR.
Ultimately successful 2001 season does not start according to plan.
The 2001 season did not, though, start according to plan. At the opening race on 4 March in
Team BMW Motorsport thereafter crossed the Atlantic in order to amass more experience by taking in two European Le Mans Series events of 2.45 hour duration each at Donington (
They're unleashed.
After its European sojourn, Team BMW Motorsport returned to the
The extent of the domination of the BMW teams became clear during the final four rounds of the series: in Mosport (
Thus the BMW teams ended the 2001 ALMS season with four consecutive one-two victories. BMW drivers mounted the top step of the podium seven times, with Jörg Müller celebrating the most: he amassed 185 points to take the drivers' title by five points from team-mate JJ Lehto. The teams' classification was won by Team BMW Motorsport (184 points), with BMW Team PTG placing third with 170. The Manufacturers' Championship went to BMW with 198 points.
In total the BMW teams had contested ten races each. For Team BMW Motorsport in particular, participation in the series proved a major logistical challenge: the team travelled nearly 7,000 miles within Europe and a further 28,000 miles in
"The technicians, the teams and the drivers performed magnificently," said BMW Motorsport Director Mario Theissen after the season finale. "The late project start, combined with the logistical challenges of the North American races, made it extremely demanding." The effort was, though, justified: the BMW M3 GTR came through its baptism of fire with flying colors.
