The Flachbau RS reinterprets the iconic 935/78 Moby Dick's slant-nose design on a 2018 911 GT2 RS, featuring reshaped bodywork, exposed carbon fiber, and a manually adjustable rear wing generating 1,221 lbs of downforce. Porsche removed 32 kg of weight and stripped the interior to race-car specifications while maintaining road legality, with extensive validation including Nürburgring testing and 150,000 km endurance simulation.
