The BMW M6 GTLM for the IMSA WeatherTech SportsCar Championship.

In 2016, BMW Motorsport introduces a brand-new GT racing car to its works involvement, in the form of the BMW M6 GTLM. The new car replaces its predecessor the BMW Z4 GTLM and heralds a new chapter in North American GT racing. A special milestone in a special year for BMW, as the manufacturer celebrates its 100th anniversary in 2016.

“The BMW M6 GTLM has all the essential ingredients to be competitive and thrill fans in the USA and Canada from the word go”, said BMW Motorsport Director Jens Marquardt. “We are very much looking forward to continuing our works commitment at the highest level and to adding another successful chapter to the history of BMW Motorsport in North American motor racing. BMW of North America and racing quite simply belong together – and it goes without saying that it will remain that way in the future. Many of our customers and fans in North America are also BMW M enthusiasts. That makes it all the nicer to be able to field another car from our sportiest line of products, in the form of the BMW M6 GTLM.”

The GT3 version of the BMW M6 had to be modified for the GTLM version, in order to comply with the ACO regulations which apply in the GTLM class of the IWSC. Even while developing the GT3 car, BMW Motorsport already took into account the changes that would be required to make it possible to start in the GTLM class. That made it considerably easier to derive the GTLM car. The BMW Motorsport engineers have been working closely with the BMW Team RLL – BMW works team in North America since 2009 - in Munich to implement the modifications as efficiently as possible. Unlike the BMW M6 GT3, the BMW M6 GTLM must not have ABS. At 1,250 kg when empty, the BMW M6 GTLM is also about 50 kilograms lighter and has a slightly longer wheelbase.

The dimensions of the wheels and tyres are also different to those on the BMW M6 GT3, as is the tank capacity. The BMW M6 GTLM achieves far faster lap times than the BMW M6 GT3, primarily because of the Michelin tyres specified in the regulations for the GTLM class.
