Even for us diehard Cayman GT4 Clubsport fans, not having a 911 GT4 car was a bit of a disappointment. So Porsche's introduction of the 911 GT4 R was an exciting development.
The new car brings the 911 platform into global GT4 racing for the first time, with its racing debut set for the 2027 season.
Under the hood, the 911 GT4 R brings a 4.0-liter six-cylinder boxer engine derived from the 911 Cup car. The engine delivers 382 kW (520 PS) and up to 470 Nm of torque. Performance levels vary according to Balance of Performance classification as required by GT4 regulations.
Power is sent through a sequential six-speed dog gearbox with steering-wheel paddle shifters and a four-disc racing clutch. The car is based on the crowd favorite road-legal 992.2 generation 911 GT3 (also the base of the 911 Cup car).
Compared with Porsche’s Clubsport models based on the 718 Cayman, the 911 GT4 R brings a more powerful engine, wider track widths, and better motorsport electronics. Porsche cites gains in lap times, drivability, and stability.
Thomas Laudenbach, Vice President Porsche Motorsport, described the car as combining “iconic 911 DNA” with Porsche’s trusted GT4 concept, adding that the move reflects the growing importance of the GT4 racing class.
The chassis differs from the 911 Cup in line with GT4 regulations. Its wheels are each one inch narrower and use a five-hole mounting pattern found on production models. Dual-adjustable dampers and three selectable spring rates give teams more set-up options.
Aerodynamics and body construction play a central role in the new model. The 911 GT4 R adopts key body structures from the 911 Cup and uses aerodynamic improvements, including a manually adjustable rear wing.
Porsche also made extensive use of natural-fiber-reinforced plastic combined with epoxy resin in the doors, engine cover, aerodynamic parts, and sections of the cockpit.
Inside, drivers receive vital information from a 10.3-inch color display. The cockpit also includes an integrated data logger and a precise GPS system to support race analysis and performance optimization.
Since entering the GT4 category in 2016, Porsche has developed and produced more than 1,500 Cayman-based GT4 racing cars.
The 911 GT4 R will line up as Porsche’s newest GT4 customer racing car from the 2027 season, bringing the 911 platform into one of the fastest-growing areas of international motorsport.
There's no doubt that GT4 teams and drivers will welcome the new option in the racing category with plenty of excitement. Pricing starts at $375,500, and we can't wait to get our hands on one for a few laps on the race track.
The time to dust off those Bell helmets has finally come. We'll see you in the paddock soon. Happy racing.
