Porsche Just Spent Three Years Turning a GT2 RS Into a Modern Moby Dick

A Modern Nose Job With a 1978 Reference

Porsche's Sonderwunsch personalization department has finished its most ambitious commission yet: the Flachbau RS, a one-off 911 GT2 RS reshaped into a modern homage to the 935/78 Le Mans racer nicknamed "Moby Dick." Built for a single customer over nearly three years, the project pulled in Sonderwunsch, Style Porsche, Manthey, Porsche Motorsport and engineers from Weissach — the kind of cross-department commitment Porsche usually reserves for its own factory racing programmes, not a customer car.

The donor is a 2018 911 GT2 RS fitted with the Weissach Package, and Porsche didn't stop at a body kit. The round headlights are gone, replaced by an entirely new lighting system of three vertically stacked LED modules for high beam, low beam and daytime running lights — their slim profile is what lets the nose actually read as a slantnose rather than a 911 wearing a costume. A manually adjustable rear wing, mounted on S-shaped supports borrowed from the 911 GT3 R, generates 554 kg of downforce over the rear axle at 340 km/h. Despite the extra aero hardware, the finished car is 31.6 kg lighter than the GT2 RS it started as — the interior was gutted at the customer's request, with the PCM system, stereo and even sound deadening and floor coverings pulled out in favour of painted metal, exposed carbon and a lightened wiring harness with every unnecessary wire removed. Power comes from the GT2 RS's twin-turbo 3.8-litre flat-six, tuned to 700 PS. The paint is Grand Prix White, a shade Porsche last used in period liveries, set off with exposed carbon fibre and matte black detailing that nods to the Martini-liveried 935/78, right down to a U-shaped graphic on the hood.

Why a Three-Year Interior Delete Matters More Than the Bodywork

The easy read on a car like the Flachbau RS is "cool throwback bodywork," but the more telling detail is what the customer asked Porsche to take out, not add. Stripping a factory one-off down to painted metal and bare carbon, then re-engineering the wiring harness itself to save weight, is a request only Sonderwunsch's motorsport-adjacent resources can actually execute — it's the difference between a styling exercise and a car built by people who also build 911 GT3 Rs for a living.

That distinction is exactly what separates Porsche's Sonderwunsch programme from a paint-and-stitching options list, and it's the level GCC collectors increasingly expect when they commission a one-off through the region's Porsche network. Dubai's Porsche base already skews toward GT and RS variants pushed further than the factory catalogue allows; a Flachbau RS is a useful reference point for what "further" can actually mean when a client is willing to give Weissach three years and a blank sheet.
