A customer asked Porsche’s Sonderwunsch division for a very specific vehicle based on their 2018 Porsche 911 GT2 RS Coupe. The company enlisted the assistance of its own Style and Motorsport divisions, invited third-party firm Manthey Racing to join in, and even contacted retired car designer Grant Larson to carry out the commission.
The commission, as you’ve probably realized if you read the title, was a vehicle that looked and felt as close as possible to the 911 Flachbau race car unleashed in 1978, known as the Moby Dick. Some fans of the German brand truly loved its design, but it never received so much as a proper production run.
The example pictured here is one-off and goes by Flachbau RS. It is fully street-legal in Germany, which probably means in most of the rest of the world, too. Larson provided the blueprints for the completely redesigned front end featuring slim LED headlights instead of the usual round lamps, as well as DRLs installed inside enlarged air intakes.
In turn, Manthey Racing came up with a unique aero kit for the ride, including a front splitter, side canards, aero hubcaps for the wheels, a rear diffuser, and a manually adjustable rear wing. The latter part is said to generate up to 554 kilograms (1,221 lbs) of downforce at the car’s top speed of 340 km/h (211 mph). Such extensive use of carbon also means that the whole thing weighs nearly 32 kilos (70 lbs) less than a stock GT2 RS.
The flat-six mill rated at 700 PS (690 hp / 515 kW) and 750 Nm (553 lb-ft) of torque continues to drive the rear wheels through the company’s seven-speed PDK transmission. We don’t know how fast it is, but Porsche claims the Flachbau RS has completed all the required homologation tests, including durability, drag performance and handling trials. It had even run 50 Nürburgring laps piloted by in-house test driver Lars Kern to ensure everything was in order.
All pricing details stay private, but Carscoops understandably believes that this one must cost well above a million euros.
