ACO still plans to make LMP1 coupe exclusive from 2010 on. They also want the prototype to resemble road cars more, especially at the front of the car.
The minimum weight for LMP2 will be increased to 775 kg in 2008.
The cost of GT2 cars should also be reduced. These would mean less electronics.
Shell is looking to bio-fuel and bio-diesel. And ACO is studying energy recuperation in particular with the rear wheels and the rear brakes.
