Porsche reveals new 911 GT4 R

Porsche has revealed its all-new 911 GT4 R in the build-up to the 2026 Spa 24 Hours, ahead of its race debut in 2027. It will replace the 718 Cayman GT4 RS Clubsport model, and is the first Porsche GT4 developed around the 911 platform.

The car is based on the Porsche 911 GT3 Cup (992.2), which debuted in Porsche’s one-make series this year, and will be powered by a 4.0-liter six-cylinder water-cooled boxer engine producing up to 520 hp, although this will be reduced in competition through Balance of Performance. Changes compared to the 992.2-spec 911 GT3 Cup, necessitated by the regulations, include the use of narrower wheels and production wheel mountings.

Compared to the current Cayman GT4, alongside increased power, the car also features wider track widths and further-developed electronics. As well as performance, the aim is that these changes will help improve drivability and stability, particularly in racing conditions.

In North America, the new 911 GT4 R is expected to compete in IMSA Michelin Pilot Challenge and SRO GT4 America during its debut year. The price for the U.S. market has been set at $375,500, including import and delivery.

Porsche first entered GT4 in 2016, and up until this point has exclusively relied on the Cayman platform, producing over 1500 cars and finding significant success, such as winning 11 titles in 2024 alone.

North American teams and drivers have earned a robust 12 driver championships in that time frame across IMSA Michelin Pilot Challenge and SRO Pirelli GT4 America. That includes a complete sweep of the 2025 manufacturer, driver (Jan Heylan and Luca Mars) and team (RS1) championships in IMSA’s GT4 championship and 2024 titles in Silver, Pro-Am and Am classes for SRO GT4 America.

“With the new race car based on the Porsche 911 GT3, we are taking our successful GT4 program to a new level. The combination of iconic 911 DNA and the tried-and-tested GT4 concept creates a unique offering in the market,” says Thomas Laudenbach, Vice President, Porsche Motorsport. “Our decision to bring the 911 platform into the GT4 category underlines the growing importance of this class in international motorsport. GT4 has evolved from an entry-level segment into a highly competitive, globally relevant racing platform.”

"In North America, the GT4 category is a strength of customer racing in open competition,” Volker Holzmeyer, Porsche Motorsport North America President and CEO, said. “The expansion of the 911 platform for use in GT4 allows for a simplified transition from Porsche one-make racing into GT4. Race drivers and teams will benefit from a shared platform with the 911 Cup across our Porsche motorsport one-make system and open competition Series across North America.”

The Porsche 911 GT4 R is on public display throughout the week at the 24 Hours of Spa.
