The main outlines of the 2011 regulations
I found a summary of the technical definitions for the 2011 Le Mans 24 Hours concern 4 precise points:
- LM P1 and LM P2 engines: reduction of power, and cubic capacity reduction in LM P1 (diesel, 3.7-litre twin turbo 8 cylinders maximum instead of 5.5 litres, petrol, normally aspirated 3.4-litre 8 cylinders maximum instead of 6 litres, petrol, 2.0-litre turbo 6 cylinders instead of 4.0 litres), in LM P2 (diesel, 4.0-litre turbo 8 cylinders, petrol, 4.0 litres prepared on the basis of 2010 GT2, petrol, 4.5-litre series production). The minimum weight in LM P1 remains at 900 kgs and is increased from 825 to 900 kgs in LM P2.
- Hybrid systems aimed at reducing fuel consumption (free development in compliance with precise rules).
- Fuel tank capacities (75 litres instead of 90 litres for petrol engines, and 68 litres instead of 81 litres for diesels).
- Wheel dimensions unchanged in relation to the 2009 regulations).

Of course, the Taurus diesel used the 5.0 V10 TDI out of the Volkswagen Toureg/Pheaton, and with no factory support from VW.
