LMP3 is the first step on the ladder for many teams and drivers before moving up to the LMP2 and even the LMP1 class (the latter in the FIA WEC and 24 Hours of Le Mans).
The 420 bhp Nissan V8 engined LMPs have been developed with cost control in mind. Costs are capped, by regulation for both the entire car, and for spares packages.
Despite that the LMP3 cars have received much praise from both Professional and Gentleman drivers as providing the power and aerodynamic downforce required to provide a driving experience that comes very close to that offered by their larger and faster LMP2 cousins.
Only Group CN cars with a carbon chassis will be eligible to race in the Asian Le Mans Series. 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.
GT3 cars are defined by a set of regulations maintained by the FIA for GT racing cars designed for use in various 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 (eg, 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.
Often featuring gentleman drivers, they also serve as development grounds for future professional drivers. 24Hrs of Le Mans Champion Earl Bamber is one example of a driver who came through Porsche Carrera Cup Asia.
