The 2013 Nissan ZEOD RC concept car was a precursor to which racing car?

The 2013 Nissan ZEOD RC concept car was a precursor to the Nissan GT-R LM Nismo racing car.

Nissan developed the ZEOD RC as an experimental Le Mans prototype using a hybrid drivetrain, narrow-track aerodynamics and electric power. The car was designed by Ben Bowlby, whose earlier DeltaWing work also influenced its distinctive shape. Nissan described the ZEOD project as preparation for a planned return to the top-level LMP1 category.

That program led into the Nissan GT-R LM Nismo, which debuted at the 2015 24 Hours of Le Mans. The later prototype retained the unconventional engineering spirit of the ZEOD RC, but used a radically different front-engine, front-wheel-drive layout for its internal-combustion powertrain, supplemented by a planned flywheel energy-recovery system.

The ZEOD RC itself raced only once, as the experimental Garage 56 entry at Le Mans in 2014, retiring early with a gearbox failure. It nevertheless completed a lap using electric power alone and exceeded 300 km/h, making it an important technology demonstrator rather than merely a styling exercise.
