How Porsche's New 911 Cup Car Supports Sustainable Gasoline Combustion

Set to headline the Porsche Carrera Cup North America and the Porsche Mobil 1 Supercup—supporting select Formula 1 races—the all-new 911 GT3 Cup car will also compete in national series across the globe. Based on the latest 992.2-generation 911 GT3, the 2026 Cup car brings a powertrain prepped for next-gen synthetic fuels.

While still running Porsche's naturally aspirated 4.0-liter flat-six, the new Cup car has been engineered to burn what's known as “Advanced Sustainable Fuel”—a synthetic blend rated at 100.5 RON. Porsche claims this e-fuel reduces carbon dioxide equivalent emissions by 66% compared to traditional gasoline.

The new high-performance fuel blend meets the FIA’s latest “Advanced Sustainable” standards thanks to a smart combination of synthetic and renewable inputs.

At the core of the blend is methanol-to-gasoline (MtG)—a synthetic fuel derived from renewable sources. It makes up the largest share of the fuel’s 79.7% renewable content by volume. To boost performance, the mix also includes ethanol made from waste and residual materials, which helps raise the fuel’s octane and oxygen content for more efficient combustion.

This cleaner-burning fuel is part of Porsche’s push to cut motorsport emissions without compromising the sounds and smells that make motorsports a spectacle.

HIF Global, the manufacturer behind the synthetic raw fuel is working to reduce carbon emissions at every step of the production process—starting at its Haru Oni pilot plant in southern Chile.

The facility is powered exclusively by renewable wind energy, even for supporting functions like grid stabilization and control room operations. To further minimize its carbon footprint, HIF offsets CO₂ emissions from fuel transport using certified carbon credits tied to South American renewable energy projects.

Porsche’s development team began work on the car in January 2024. Testing has already taken place at Monza, the Lausitzring, and at Porsche’s own Weissach proving grounds. Updates include refined aerodynamics at the front end, an enhanced braking system, revised suspension, upgraded electronics, and a tweaked transmission—all rooted in lessons learned from race teams running the outgoing model introduced in 2021.

“We are already operating at a very high-performance level with the current GT3 Cup,” said Jan Feldmann, Project Manager for 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 to the current Cup 911.”

Production of the 2026 Porsche 911 GT3 Cup will begin this fall—look for the new e-fuel-ready race car to debut across global one-make championships starting in 2026.
