The PORSCHE 911 RSR (2013) was made for the 2013 season of the World Endurance Championship where it was driven by PORSCHE Team Manthey. This car won its class in the 2013 24 Heures du Mans. It was altered for the 2014 season. This is based on the 911 Carrera model because the 991 GT3 model was not in production at the time. Under the hood, the car is powered by a 4.0-litre six-cylinder boxer engine, producing approximately 460 bhp (brake horsepower).
