A personal brief becomes a one-off
A Porsche customer asked for a nearly new 911 GT2 RS to be transformed into a factory bespoke car. Sonderwunsch and Manthey developed a road-legal Flachbau design that references the 935/78 racing car known as Moby Dick.
This is a commissioned collector’s vehicle rather than a newly announced production model. The original customer’s design brief shaped the finished car’s appearance and engineering.
The historic racing reference
The exterior uses Grand Prix White, reshaped front wings and a prominent U-shaped bonnet graphic. A rear wing influenced by the 911 GT3 R rennsport completes the distinctive profile.
Porsche presents those details as a visual tribute to a historic racing machine. They do not make this GT2 RS a surviving example of the original 935/78.
Engineering to match the bodywork
The programme included development of new parts and extensive validation work, not merely a respray. Porsche says weight-saving changes reduced the car’s mass by a further 31.6 kilograms.
That number belongs to this individual build and should not be assigned to a standard GT2 RS. The altered design also underwent work to maintain its suitability for road use.
A modern collectible
The result shows how a factory personalisation commission can draw upon a marque’s racing history. This particular design turns a recognisable shape into a modern customer project with its own specification.
The official Porsche release and project photographs document the finished one-off. No general allocation, repeat production run or retail price for identical cars was announced.
