Porsche Unveils New 911 GT3 Cup With Sharpened Performance and Sustainable Focus

Summary

• The next-gen 911 GT3 Cup debuts summer 2025, with production starting in fall and a racing rollout planned for the 2026 season
• Key upgrades include enhanced aerodynamics, revised cockpit design, and refined handling, all based on the updated 992.2 platform
• Developed exclusively on Porsche’s eFuel blend, the car signals a shift toward more sustainable motorsport without compromising performance

Porsche is gearing up to launch their next-generation 911 GT3 Cup car — a sharpened, track-focused evolution of its iconic one-make racer, now based on the updated 992.2 platform. Set to make its world debut later this summer, the new GT3 Cup marks a significant step forward in the brand’s motorsport lineage, bringing updated aerodynamics, refined handling, and sustainable fuel integration to the grid.

Developed entirely at Porsche Motorsport’s Weissach facility, the car has undergone extensive testing across three circuits — Monza, Lausitzring, and Porsche’s in-house test track — with seasoned drivers including Bastian Buus and Klaus Bachler helping dial in feedback. The result is a chassis and powertrain package that stays true to its naturally aspirated roots, while pushing forward in precision and balance.

At its core remains Porsche’s high-revving 4.0-liter flat-six, now producing around 503 hp, paired with a sequential transmission and reworked driveline components for faster shifts and greater durability. The car’s aerodynamics have been overhauled, with a redesigned front end featuring wider cooling intakes, integrated hood vents, and a revised splitter to increase front-end grip. A wider rear track and improved underbody flow balance out the downforce profile.

The cockpit has also undergone thoughtful revision. A redesigned steering wheel, updated digital dash, and optimized pedal layout reflect input from professional drivers across global Cup series, ensuring the driving experience remains both intuitive and focused. Subtle tweaks to seat ergonomics and visibility enhance driver comfort and situational awareness during high-intensity stints.

One of the most significant updates lies beneath the surface. For the first time, the car has been developed exclusively on Porsche’s eFuel blend — a high-performance synthetic fuel aligned with FIA’s Advanced Sustainable regulations. Comprised of 79.7% renewable components, the blend delivers a 66% reduction in lifecycle CO2 emissions versus fossil fuel, without compromising output or responsiveness. It’s a forward-thinking integration that nods to Porsche’s broader sustainability roadmap while staying grounded in real-world racing demands.

Built at Porsche’s main facility in Stuttgart-Zuffenhausen, the 992.2 GT3 Cup will begin production in fall 2025 and officially enter competition in the 2026 season. Set to headline the Porsche Mobil 1 Supercup and select Carrera Cup championships worldwide, the new 911 GT3 Cup combines sharpened performance, a modernized cockpit, and a forward-looking approach to sustainability — pushing Porsche’s one-make legacy into a new era of racing.
