Porsche teases a street-legal hypercar inspired by its Le Mans racer—possibly built for racing icon Roger Penske.
Porsche is putting the finishing touches on a street-legal version of its dominant 963 LMDh Le Mans racer, and signs point to a very exclusive destination—perhaps even the private collection of motorsport legend Roger Penske.
Referred to as the Porsche 963 RSP, this one-off hypercar is being crafted with clear ties to Porsche’s high-performance racing pedigree. A recent teaser video shared by the automaker reveals Porsche’s expert craftsmen hand-assembling the car's components, from cutting Alcantara for the cabin to sanding bespoke carbon fiber bodywork.
Though road-legal, the RSP reportedly remains remarkably true to its IMSA and WEC competition sibling. Changes appear limited to essential upgrades such as modified lighting, wing mirrors, and safety features. Inside, Porsche has upgraded the racing cockpit with premium materials while preserving much of the original layout’s stripped-down aesthetic.
The powertrain, a hybridized 4.6-liter twin-turbocharged V8, is expected to closely mirror that of the race car. In competition, the engine is limited to 670 horsepower to meet regulatory standards, but the absence of racing restrictions in this road-going version could allow for significantly more output.
Speculation around the car’s final owner centers on Roger Penske, the man behind Porsche’s factory racing efforts. The initials “RSP” match his own, and Penske led the Porsche 963 to championship success in 2023 across both IMSA and the World Endurance Championship.
This isn’t the first time Porsche has built a bespoke hypercar for a notable partner. In 1975, Count Gregorio Rossi di Montelera of Martini & Rossi fame received a road-legal version of the 917K.
If confirmed, the 963 RSP would not only represent a fusion of cutting-edge engineering and heritage, but also highlight the storied relationship between Porsche and one of motorsport’s most revered figures.
