The Nissan GT-R LM Nismo was a sports prototype racing car built by the Nissan Motor Company and their motorsports division Nismo. Designed for the Le Mans Prototype 1 Hybrid (LMP1-H) regulations of the FIA World Endurance Championship and the 24 Hours of Le Mans, the GT-R LM was unique amongst Le Mans Prototypes at the time for utilizing a front mid-engine layout for its internal combustion engine as opposed to the rear mid-engine layout used by nearly all other competitors in the category. It was Nissan's first prototype since the R391 competed in 1999, although the company had supplied engines in recent years. The car was branded after the Nissan GT-R road car and shares similar engine and drivetrain configurations, but is not related to the sports car. The GT-R LM Nismo program was announced on 23 May 2014, while the car was publicly shown for the first time in a Nissan commercial during Super Bowl XLIX on 1 February 2015. The car was retired from competition at the end of 2015 after having competed in only one race.
Chief designer Ben Bowlby was given the brief from Nissan to not design an "Audi copy". Bowlby placed the GT-R LM's combustion engine in front of the cockpit, a layout that has not been used in Le Mans prototypes since the Panoz LMP01 Evo in 2003. Unlike the Panoz's rear-wheel drive powertrain, the GT-R LM powers the front axle through a gearbox located in front of the engine.
The engine, co-developed by Nissan and Cosworth, is a 3.0 L (180 cu in) 60-degree V6 with dual turbochargers and direct injection, and is seen by Nissan as the most fuel efficient design. Behind the engine and beneath the cockpit is a kinetic energy recovery system using two flywheels developed by Torotrak. The flywheels gain energy from the use of the front brakes then discharges that energy back to the front wheels via a driveshaft running over the top of the combustion engine. The flywheels can also output power to a secondary driveshaft which is connected to a limited-slip differential at the rear of the car which feeds epicyclic gearboxes located in each rear wheel hub, allowing the GT-R to be all-wheel drive if necessary. The combustion engine outputs approximately 500 hp (370 kW; 510 PS) while the flywheel system is intended to have an additional output of approximately 750 hp (560 kW; 760 PS).
