Porsche has developed the 911 Cup for the 2026 season and will give it its world debut this summer. The optimized one-make cup race car is based on the current 992.2 generation of the 911 and has already largely completed its development phase. The 911 Cup will run in the Porsche Mobil 1 Supercup (PMSC) and in selected Carrera Cup series, including Porsche Carrera Cup North America, from the start of the 2026 season.
The Porsche 911 has provided the basis for the sports car manufacturer’s one-make cup racing series since 1990.
In the current season, Carrera Cup competitions are taking place in more than 12 countries in Asia, Australia, the Middle East, North and South America and Europe. In addition, there are 23 Porsche-sanctioned Sprint and Endurance Challenges and Trophies, which also use the 911 GT3 Cup for their races.
The Cup cars are produced alongside 911 series models at the main plant in Stuttgart-Zuffenhausen, Germany.
Dynamic development phase on three demanding racetracks
Work on the new competition vehicle began at Porsche Motorsport in Weissach, Germany, in January 2024. Like its predecessors, the 911 Cup combines series production technology with high-caliber motorsport attributes. Among other things, development focused on improving the aerodynamics of the front end to improve drivability, as well as improving the vehicle electronics, brakes, transmission and the six-cylinder boxer engine. Vehicle handling was also considered. “We are already operating at a very high performance level with the current GT3 Cup,” said Jan Feldmann, project manager for GT racing cars at Porsche Motorsport. “This has allowed us to focus more on feedback from the global one-make cups and develop a racing car that has been refined in many areas compared with the current Cup 911.”
Real-world test drives took place on the Italian Grand Prix circuit in Monza, at the Lausitzring in Germany and on the in-house track at the Weissach development center.
Test program exclusively with e-fuel blend
The e-fuel blend used in the 2025 PMSC meets the technical specifications of the Fédération Internationale de l’Automobile (FIA) Appendix J requirements for renewable fuel.
With all combined CO2 reduction measures, the fuel corresponds to a total CO2e reduction of 66% compared with a fossil fuel equivalent. The proportion of renewable components in the performance-specialized racing fuel blend is 79.7% by volume. Renewable synthetic raw gasoline, known as MtG (methanol-to-gasoline), makes up the largest proportion of the mix. Other blending components include renewable, waste-based or residual-based ethanol, which is used to increase the oxygen content in the fuel and the octane rating, among other things. The octane rating is 100.5 RON. The racing fuel blend was developed specifically for the boxer engines used in motorsport, and combines high performance with the highest proportion of renewable blending components possible.
