The category below the top LMP1 class of the FIA World Endurance Championship, LMP2 is a key part of the “Endurance” family which allows teams, as well as drivers, to gradually progress to the highest level. The “Le Mans Prototype 2” (LMP2) class is reserved exclusively for privateer teams independent of constructors and/or engine suppliers.
LMP2 cars have similar characteristics to LMP1 (carbon monocoque chassis) while respecting strict cost criteria: price-capped new open cars at €388,500. For closed cars the price must not exceed €463,500. The price of engines is capped at €86,778. Until 2017, different engines (Nissan, Honda, Judd) are allowed to race and many chassis (such as ORECA, Morgan, Zytek/Gibson, HPD, Dome, Ligier, Alpine, BR Engineering) are available, allowing customers an infinite number of possible combinations!
Each driver line up must be made up of at least one “Silver”or “Bronze” rated driver.
Launched by the ACO in 2015, LMP3 is a new category of junior sports-prototype for endurance racing. In the pyramid of “Le Mans Prototypes,” LMP3 becomes the first step on the ladder before moving up to the LMP2 and LMP1 classes (the latter in the FIA WEC and 24 Hours of Le Mans).
The thinking behind this car is that there should be fewest number of constraints possible, whether those are budgetary, technical, driving or operation. The sale price of the new car, complete, must not exceed €211,000.
The chassis and bodywork of LMP3 can be built by six manufacturers which have been designed by the ACO : Ginetta, Ligier, Adess, Dome, Norma and Riley. They are very close to those of the current LMP2 (closed cockpit, carbon chassis with tubular steel roll cage). The powertrain consist of a Nissan 420 bhp normally aspirated V8 engine, and an X-Trac gearbox. It is identical for all chassis, and marketed by the ORECA company which also provides specific assistance to teams.
The driver line up must be made up of at least one “Bronze” rated driver. Platinum drivers are not allowed in the LMP3 driver line-up.
For the Asian Le Mans Series, the GT category encompasses GTE, FIA GT3 and GT 300 Japan cars.
GTE cars are production-based Grand Touring cars with limits and specifications as defined by the ACO for Le Mans endurance racing. They are subjected to a Balance Of Performance to ensure parity amongst manufacturers.
GT3 cars are defined by a set of regulations maintained by the FIA for grand tourer racing cars designed for use in various auto racing series throughout the world. The regulations allow for a wide variety of car types to be homologated with almost no limit on engine sizes and configurations or chassis construction or layout. However, cars must be based on mass production road car models. Performance of all GT3 cars are regulated, either by the GT Bureau of the FIA or by a series’ specific ruling body (example, the ACO), through a Balance of Performance that adjusts limits on horsepower, weight, engine management, and aerodynamics to prevent a single manufacturer from becoming dominant in the class.
GT 300 Japan similarly to GTE and GT3, are based on production models and have no more than 300bhp. Their limits and specifications are defined by regulations set by the JAF.
The GT Cup (formerly known as GT Am) category in the Asian Le Mans Sprint Cup (Asian LMSC) and Asian Le Mans Series (Asian LMS) is open to cars that have been homologated for various one-make series around the world. Prestigious brands such as Ferrari, Porsche and Lamborghini organise the popular Ferrari Challenge, Porsche Carrera Cup and Lamborghini Super Trofeo across different continents. Often featuring gentleman drivers, they also serve as development grounds for future professional drivers. 24Hrs of Le Mans Champion Earl Bamber is one such driver who came through Porsche Carrera Cup Asia.
Particular only to the Asian Le Mans Series, Group CN cars with a carbon chassis are eligible to race though this eligibility will end in 2017. Only cars holding a FIA CN Homologation (chassis) using a carbon survival cell and a Group N 2 Litre engine are eligible and the ACO has established the following list of eligible cars:
LIGIER JS 53 EVO; NORMA M20 FC; LOBART LA01; PESCAROLO 02; PROMEC PJ199; TATUUS PY 012; WOLF GB08; ZULLTEC CZ2.
