New model for the Porsche Mobil 1 Supercup and Carrera Cup series
Atlanta., July 18, 2025 (GLOBE NEWSWIRE) — The new Porsche 911 Cup will make its world debut this summer. The comprehensively optimized one-make cup race car based on the current 992.2 generation of the 911 has already largely completed its development phase. The 911 Cup will be used in the Porsche Mobil 1 Supercup and in selected Carrera Cup series including Porsche Carrera Cup North America from the start of the 2026 season.
Since 1990, the Porsche 911 has provided the basis for the sports car manufacturer’s one-make cup racing series. What began at the time with the German Porsche Carrera Cup and expanded three years later to include the Porsche Supercup as part of selected Formula 1® Grand Prix races has long since developed into a global success story. In the current season, Carrera Cup competitions are taking place in more than twelve countries around the world: from Japan and Asia to Australia and the Middle East, from North and South America to Europe. In addition, there are 23 Porsche-sanctioned Sprint and Endurance Challenges and Trophies, which also use the 911 GT3 Cup for their races. This is also reflected in the production figures: with 5,381 units now built, the 911-based one-make cup cars are among the most produced racing cars in the world.
The Cup cars are produced side by side with 911 series models at the main plant in Stuttgart-Zuffenhausen. The current model, which debuted in the 2021 season, alone has been produced 1,130 times. Production of a Type 992.1 Porsche 911 GT3 Cup took just under eight hours.
Dynamic development phase on three demanding racetracks
Work on the new competition vehicle began at Porsche Motorsport in Weissach in January 2024. Like its predecessors, the 911 Cup once again combines series production technology with high-caliber motorsport attributes, transforming it more than ever into a thoroughbred racing car. Among other things, development focused on improving the aerodynamics of the front end, which improves drivability. In addition, there are numerous improvements to vehicle electronics, brakes, the transmission and the six-cylinder boxer engine, as well as vehicle handling. “We are already operating at a very high-performance level with the current GT3 Cup,” Jan Feldmann, Project Manager for GT racing cars at Porsche Motorsport said. “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 to the current Cup 911.”
Real-world test drives took place on the Italian Grand Prix circuit in Monza, at the Lausitzring in Brandenburg and on the in-house track at the Weissach development center. Two former Porsche Juniors took turns at the wheel: Bastian Buus from Denmark, Porsche Mobil 1 Supercup champion in 2023, and Klaus Bachler. The Austrian won the FIA Endurance Trophy for LMGT3 drivers in 2024, among other things. Laurin Heinrich, 2024 IMSA champion in the GTD Pro class, and Marco Seefried, a very experienced racer, also spent time driving the prototypes.
Test program exclusively with eFuel blend from Porsche Supercup
The eFuel blend used in the 2025 Porsche Mobil 1 Supercup (PMSC) technically meets the new Fédération Internationale de l’Automobile (FIA) Appendix J requirements for renewable (“Advanced Sustainable”) fuel, and with all combined CO2 reduction measures,* corresponds to a total CO2 equivalent reduction of 66 percent compared to a fossil fuel equivalent. The proportion of renewable components in this performance-specialized racing fuel blend is 79.7 percent 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 possible proportion of renewable blending components.
*HIF, the manufacturer of the raw fuel used for the racing fuel blend, is taking several measures at its Haru Oni pilot plant in Chile to keep CO2 emissions from production as low as possible. Among other things, the electricity required for grid connection and control room stabilization is sourced exclusively from renewable wind energy. At the same time, CO2 emissions from transport are offset by CO2 certificates from South American renewable energy plants for the provision of biogenic CO2 for eFuel synthesis. This means that, as far as possible, all elements in the supply chain can demonstrate a reduction in CO2 emissions. HIF has set itself the goal of obtaining the CO2 required for the synthesis process from a direct air capturing (DAC) plant in the future. Development is being driven forward in collaboration with partners. To minimize the need for grid stabilization, HIF is also integrating a dynamic battery storage system to act as an energy buffer. This will enable HIF to transfer important findings from the pilot plant to potential series production plants.
