The 911 RSR, which has undergone various modifications for the 2015 season, made its debut in 2013 as the predecessor of the successful 911 GT3 RSR. It is based on the seventh generation of the iconic 911 sports car. As with the production vehicle, the wheelbase grew by about ten centimetres. A new

The six gears are selected via paddles on the steering wheel. The 470 hp, four-litre six-cylinder boxer engine was taken from the predecessor and extensively optimised
