2026 Porsche 911 Cup 992 ll
By Lorenzo Bianchi August 9, 2025
New 4.0-liter flat-six produces 520 PS (382 kW), an increase of 10 PS over the outgoing Cup model.
Revised aero package includes a redesigned front end, integrated fender louvers, new underbody, and updated swan-neck rear wing.
Production starts in fall 2025, with first competition outings in the 2026 Porsche Mobil 1 Supercup and Carrera Cup series worldwide.
Evolution in Form and Function
The 2026 Porsche 911 Cup 992 II doesn’t just wear a new front bumper for the sake of a facelift — every change here has been made with a stopwatch in mind. The nose now incorporates integrated fender louvers and airflow turning vanes to manage turbulence and keep the front axle planted. Beneath the car, a tidier underbody design smooths airflow, improving high-speed stability.
At the back, the familiar swan-neck rear wing remains, but now uses partially recycled carbon in its construction. It still delivers the downforce customer teams expect, while supporting Porsche’s ongoing push toward more sustainable materials in motorsport.
The result is a car that should offer more stability in fast corners and better balance under braking — critical in one-make racing where the margins are often measured in tenths.
More Power from a Familiar Heart
Sitting behind the driver is a 4.0-liter naturally aspirated flat-six that now produces 520 PS — a 10 PS bump from the outgoing Cup car. Peak revs still climb to around 9,000 rpm, and the engine keeps its individual throttle bodies for razor-sharp response.
Porsche’s goal here hasn’t been to reinvent the wheel. The focus is on refining what works, giving teams and drivers an engine that’s just as reliable as before but with a bit more urgency out of slower corners and a stronger pull along straights.
Development and Testing
Porsche Motorsport began work on the new Cup car in January 2024 at its Weissach base. The testing program covered a mix of simulation work and on-track sessions at circuits including Monza and Lausitzring, chosen to evaluate both top-end speed and mechanical grip in varied conditions.
The lessons learned have shaped a package that aims to be faster over a race distance while remaining approachable for the wide range of drivers who compete in Porsche’s one-make series — from seasoned professionals to ambitious amateurs.
Production and Race Debut
Production of the 911 Cup 992 II will begin in fall 2025 at Porsche’s Zuffenhausen facility. The car’s competitive debut is scheduled for the 2026 Porsche Mobil 1 Supercup season, followed by rollout to regional Carrera Cup championships across the globe, including in North America, Asia, and Australia.
To simplify branding, Porsche is dropping the “GT3” label from the name. From now on, customer racing versions will simply be known as the “911 Cup,” creating a clearer identity across all one-make competitions.
