LMP1 class to ban V10/V12 engines

In order to slow speeds the ACO has made it official that engines with no more than 4 litres and 8 cylinders can enter the LMP1 class by 2011 and LMP2 class will use production engines, which means either a move to LMP1 or using modified production engines which Porsche has already been developing a Directinjection V8 which saw its way in cars running in ALMS last yr.

This means Audi will have to go back to design a V8 Diesel no bigger than 4.0 litres. These rules will go into effect in 2011 and Hybrids such as Peugeots will be able to run this years LeMans but a class will be created next year for Hybrids and Electric LMP's.
If Audi decides to run LMP1 past 2011 this means Audi quite possibly will have a high performance V8 Diesel to put in a few selected Audis such as the RS4 and R8.
