The Porsche 911 RSR is powered by a 4.2-litre flat six-cylinder engine.
Porsche says that the new 911 RSR is 95 per cent new and is powered by a bigger 4.2-litre flat six-cylinder engine that churns out 508 bhp. It's the largest ever boxer engine to be mounted in a Porsche 911 and offers a wider rev-band compared to its predecessor. Power is delivered to the rear wheels via a weight-optimised sequential six-speed gearbox. The new drivetrain also ensures faster gear-shift times and increased efficiency. The two exhaust pipes now exit on each side in front of the rear wheels. The new exhaust gas ducting saves weight and is aerodynamically advantageous.
