Porsche's Flachbau RS: a one-off GT2 RS inspired by the 935 Moby Dick
Porsche's Sonderwunsch division built a one-off 991.2 GT2 RS called Flachbau RS, a road-legal slant-nose homage to the 935 Moby Dick designed by Grant Larson. It adds new aero elements, revised front wings, louvres, and a three-position rear wing delivering up to 554 kg downforce, while shedding about 31.6 kg. The drivetrain remains near-stock (roughly 700 hp, 553 lb-ft, 0–62 mph in 2.8 s, 211 mph) with a stripped interior and lighter wiring. It completed 50 Nürburgring laps for validation with Manthey aero work, confirming stability at speed while keeping road legality.
