Changes to the regulations
For the 24 -hour race of 2011, the Automobile Club de l' Ouest since 2007 saw the first time before serious changes to the regulations, concerning both the prototypes as well as Gran Turismo.
After the rule changes of the ACO LMP1 vehicles should be slowed down so that the lap times no longer fall below the mark of 3:30 minutes. The upper limit for the displacement naturally aspirated engines was set at 3.4 liters, for turbo gasoline engine to 2.0 liters and 3.7 liters turbo diesel. Although LMP1 cars from the period to 2010 were allowed to continue to participate, but had smaller air restrictor, use lower boost pressure and smaller fuel tanks. The F-duct, which was originally planned for 2011, was banned.
In the LMP2 class costs should be saved in the first place. Prescribed were now standard based engines. Naturally aspirated engines were allowed a maximum of 5.0 liters and 8 cylinders have turbo engines, however, only 3.2 liters and 6 cylinders. Diesel engines were not admitted. A LMP2 car could cost a maximum of 400,000 euros, the upper limit for the chassis and 325.000 Euro for the motor 75,000 euros was. On a LMP2 car had to start at least an amateur.
The 24 -hour race in 2011 should be environmentally friendly. Hybrid drives were largely allowed with the changes in the regulations, including an energy recovery system similar to the KERS in Formula 1, wherein the stored energy is used automatically when the accelerator pedal. Hybrid vehicles could also use four-wheel drive. The minimum weight for all prototypes was 900 kilograms. In addition, had to be mounted on the hood in the body of the prototype, a vertical fin. This should reduce the tendency to lift and prevent serious accidents such as the Mercedes- Benz CLR 1999.
The separate class for GT1 cars was abolished. For the GT2 class was upgraded and divided into amateur and a professional class. In the amateur class vehicles were allowed to start, which were occupied maximum on the technical levels of the previous year and at least one amateur racer. The GT1 cars of 2010 would have been admitted for the GT- amateur class, but took no such vehicle part.
At the teams that reached 2010 top rankings in high class sports car racing and sports car racing series of the year, automatic invitations for the 24 - hour race at Le Mans were awarded in 2011. To the respective first and second in the LMP1, LMP2 and GT2 class of the previous race and the Le Mans Series, the winner of the Petit Le Mans, the American Le Mans Series, the Intercontinental Le Mans Cup and the winner of the Michelin Green X came Challenge within the LMS. From the FIA GT Championship got no team an automatic invitation as opposed to past years.
