Technical regulations
As of 2011, the main technical regulations for the LMP class cars are as listed below:
LMP1[3] - intended especially for manufacturers: minimum weight of 900 kg (1984 lb). Naturally aspirated engines limited to 3400 cc (207.5 ci). Turbochargers and superchargers allowed for petrol engines with a maximum displacement of 2000 cc (122 ci) and for diesel engines with a maximum displacement of 3700 cc (225.8 ci), restrictor-limited to around 700 bhp. No limits on the number of cylinders for any type of engine. Fuel tank size of 83 litres (16.5 gallons) for petrol engines, 76 litres (16 gallons) for hybrid petrol engines, 60 litres (13.2 gallons) for diesel engines and 58 litres (12.8 gallons) for hybrid diesel engines. Wheel size (maximum diameter) of 28.5 inches (720 mm) and maximum width of 16 inches (410 mm). LMP1 cars are generally the most powerful, with faster straightaway speeds. For hybrids with electric acceleration on the front wheels, the system can only activate above 120 km/h to prevent traction advantages out of corners; there is no such restriction for electric acceleration on the rear wheels.
LMP2[4] - intended especially for privateers: minimum weight of 900 kg (1984 lb) or 920 kg (2028 lb) for 2010 cars in 2011 configuration. Only production-based engines are allowed in LMP2 with diesel engines permitted from 2013 onwards. Naturally aspirated engines limited to 5000 cc (305.1 ci) with a maximum of eight cylinders. Turbocharging and supercharging are allowed for petrol engines with a maximum displacement of 3200 cc (195.3 ci) and a maximum of six cylinders, restrictor-limited to around 450 bhp. Fuel tank size of 75 litres (16.5 gallons) all type of engines. Wheel size (maximum diameter) of 23 inches (580 mm) and maximum width of 14 inches (360 mm).
LMPC - Le Mans Prototype Challenge. This class consists of competitors running identical Oreca FLM09 cars and spec engines.
Biofuels, specifically petrol with 10% ethanol and biodiesel (BTL), are allowed in both categories.
Both classes allow open or closed-cockpit designs (closed cars must have a windscreen, a roof, and doors on each side). New for 2011, all cars must have fins on the rear bodywork to prevent them from rolling over in the air during crashes. Although a passenger seat is not used, cars have to be designed to carry two people. The empty area of the cockpit is therefore usually used to hold electronic devices and cooling equipment.
Dimensions for LMP1s, starting in 2014, are limited to a maximum of 4650 mm (183.1 in) in length, 1900 mm (74.8 in) in width, and 1050 mm (41.3 in) in height (from the bottom of the bodywork, not the ground). LMP2s can still be constructed to the old dimensions of 4650 mm (183.1 in) in length, 2000 mm (78.7 in) in width, and 1030 mm (40.6 in) in height. Bodywork is also required to cover all mechanical elements of the car, so that it cannot be visible when the car is viewed directly from the front, side, or top.
