On the eve of the 2025 24 Hours of Le Mans, Porsche is making a big splash by unveiling the 963 RSP, a brand-new road-going version of its 963 endurance racer. This unique project, which echoes the German brand’s prestigious history, is not intended for mass production, but illustrates Porsche’s ability to build on its heritage to innovate in the automotive sector. The 963 RSP, which made its debut near the legendary Circuit de la Sarthe, combines authentic design, cutting-edge performance, and road-ready comfort, marking a remarkable snub to the world of racing and a new milestone in the history of luxury sports cars approved for the general public. This version, created especially for Roger S. Penske, director of Porsche Penske Motorsport, is directly inspired by the 917 « Count Rossi » which, fifty years ago, gave birth to a road model intended for an illustrious client. The homage to this track icon is reflected in the Martini silver design, in the masterful use of composite materials such as carbon fiber and Kevlar, as well as in the choice of an interior combining leather and beige Alcantara. Porsche, through this version, demonstrates how innovation can draw on a rich tradition to design an exceptional automobile, between sportiness and luxury, between track and road.
The 963 RSP stands out not only for its aesthetics but also for technical adjustments designed to make it road-ready while retaining the power and performance characteristic of the 963 race car. The hybrid powertrain, featuring a 4.6-liter twin-turbo V8 delivering nearly 680 horsepower, remains mechanically unchanged, with the exception of a reprogramming of its management system to smooth out the power delivery. This pragmatic consideration of the constraints of road traffic, while retaining the spirit of a true racing car, underscores Porsche’s ability to combine performance and practicality.
Key technical features of the road-going Porsche 963 RSP
Transforming an endurance car into a road-going model requires numerous adjustments to ensure not only an accessible driving experience but also compliance with automotive standards. The Porsche 963 RSP is based on the racing 963, celebrated in the FIA World Endurance Championships (WEC) and IMSA WeatherTech.
The main modifications concern:
🛠️
- Suspension: Adoption of softer Multimatic DSSV dampers than those of the racing version, for increased comfort and better ground clearance. 🚗
- Body: Raised to reduce road infrastructure constraints, with covered wheel arches to meet standards. 💡
- Lighting: Headlights and taillights redesigned to operate according to road car standards, with homologated lighting. ♻️
- Powertrain: 4.6-liter twin-turbo V8 hybrid with approximately 680 horsepower, with a reprogrammed control unit to improve power delivery for everyday use. 🛡️ Road safety and equipment:
- Installation of a horn, license plates, and rain-resistant Michelin tires with a vintage sidewall design. 🛋️ Interior:
- Ventilated but more padded seats, fixed headrests, a 3D-printed cup holder, and a dedicated laptop compartment for starting and controlling the car. These adaptations allow this sports car to meet a real challenge: offering an authentic endurance racing experience while ensuring proper and comfortable road use.

The Porsche 963 RSP is more than just a road car; it embodies a vibrant tribute to the legendary Porsche 917 “Count Rossi”, an avant-garde model launched at the end of the 1970s which left a lasting mark on the history of endurance. For this new version, Porsche strives to ensure that every detail evokes this exceptional model, both aesthetically and symbolically.
