context_page_description: A Le Mans Prototype is the type of sports prototype race car used in the 24 Hours of Le Mans, FIA World Endurance Championship, WeatherTech SportsCar Championship, European Le Mans Series and Asian Le Mans Series. Le Mans Prototypes were created by the Automobile Club de l'Ouest. The technical requirements for an LMP include bodywork covering all mechanical elements of the car.
  While not as fast as open-wheel Formula One cars, LMPs are the fastest closed-wheel racing cars used in circuit racing. Le Mans Prototypes are considered a class above production-based grand tourer cars, which compete alongside them in sports car racing.
  Modern LMP designs include hybrid cars that use electric motors to assist acceleration. The Le Mans Prototype LMP1 class will be replaced by Le Mans Hypercars in the FIA World Endurance Championship, and the 24 Hours of Le Mans from the 2021 season, but LMP1 cars will be eligible to be "grandfathered" for one final season, to compete alongside the new class for the 2021 season.
context_section_description: LMP3 is an entry-level prototype class intended for introducing young drivers and new teams to endurance racing before they progress to the higher classes of prototype racing, LMP2 and ultimately LMP1. LMP3 uses closed-cockpit chassis, which can be built by any licensed constructor, powered by a 5-litre normally-aspirated Nissan V8 engine. The class is in use since 2015. In 2017, the International Motor Sports Association announced the addition of the LMP3 cars to the IMSA Prototype Challenge, becoming the top class in the category; this allows the vehicle to race in either series.
  The cars currently eligible for use in the class are: Ginetta-Juno P3, Ligier JS P3, Norma M30, ADESS-03, and the Ave-Riley AR-02. The cars are eligible in a number of series, such as the Asian Le Mans Series, the European Le Mans Series, as well as the V de V Endurance Series and the IMSA Prototype Challenge. A number of championships for the class have also been created, such as the FRD LMP3 series and the British LMP3 Cup.
  A 2nd Generation ruleset will be introduced for 2020, with new cars set to be introduced, namely the Ginetta G61-LT-P3, Ligier JS P320, Duqueine D-08, and the ADESS-03 Evo. These cars can be built from its predecessors using an upgrade kit.
