LMP2
LM P2 De LM P2-klasse is de klasse voor de ‘goedkopere’ prototypes, met een minimumgewicht van 750 kg. De toegestane motoren hebben een inhoud van 3,4 liter voor de atmosferische motoren en een maximuminhoud van 2 liter voor de turbomotoren. Voorbeelden: Porsche RS Spyder en de Lola B08/80. In 2004 voldeed alleen Lola-Judd nummer 32 aan de regels voor LM P2. Kleur: Blauw.
LMP2
Until 2016, LMP2 allows both open and closed-cockpit designs (closed cars must have a windscreen, a roof, and doors on each side), while only closed-cockpit design is allowed for LMP1 as it is much faster and for safety. As of 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 must be designed to carry two people. The empty area of the cockpit is usually used to hold electronic devices and cooling equipment. Only production-based engines were allowed in LMP2 with diesel engines permitted from 2013 onwards.
From 2017, in order to limit the costs, FIA will introduce a new set of regulations, which will be locked in through 2020, aiming a significant power increase, to the range of 150 horsepower (which is expected to led to a four-second decrease in lap time at Le Mans). Gibson Technology will be the exclusive engine supplier, producing a four-litre normally-aspirated V8.[5]
Dallara, Onroak Automotive (Ligier), Oreca and the joint-venture Riley Tech/Multimatic were selected by FIA as the four exclusive chassis constructors,[6] which must be closed-cockpit designs.
