Porsche has officially unveiled its newest entry into the GT4 racing series, the 911 GT4 R. This marks a pivotal moment as it is the first GT4-spec racing vehicle to be based on the iconic 911 platform, departing from the long-standing tradition of utilizing the 718 Cayman. The 911 GT4 R is engineered to compete in prestigious events such as the SRO GT4 America and the IMSA Michelin Pilot Challenge, alongside various factory-supported, single-make racing competitions. With an expected launch price of $375,000, this high-performance machine is poised to make its competitive debut in the 2027 motorsports season.
The transition to the 911 platform brings a host of enhancements compared to its predecessor, the 718 Cayman RS Clubsport. Built upon the foundation of the 992.2 911 Cup race car, the new GT4 R benefits from broader front and rear track widths, integrating advanced motorsports technologies. A key highlight is its formidable 4.0-liter flat-six engine, which is capable of generating up to 513 horsepower and 346 pound-feet of torque. While these power figures will be adjusted to comply with Balance of Performance (BoP) regulations, the car is uniformly equipped with a sequential six-speed dog 'box, enabling rapid gear changes via paddle shifters and a four-disc racing clutch.
Matthias Scholz, Director of GT Racing Cars at Porsche Motorsport, emphasized that the 911 embodies Porsche's motorsport heritage like no other vehicle, and adapting it for GT4 racing unlocks new dimensions in performance and driving sensation. He noted that the 911 GT4 R incorporates detailed developments initially refined for the 911 Cup, underscoring a continuous evolution in Porsche's racing division.
Despite sharing many structural elements with the 911 Cup car, the GT4 R features specific chassis modifications to meet distinct class requirements. These include a five-lug bolt pattern, a departure from the more intricate center-lock design, and slightly narrower wheels. Nevertheless, drivers will appreciate the flexible suspension tuning, offering dampers with two adjustment settings and a choice of three spring rates. Aerodynamic components, doors, and the engine cover are crafted from lightweight yet robust natural-fiber-reinforced plastic. The cockpit is driver-centric, featuring a 10.3-inch digital display for crucial data, complemented by an integrated data logger and GPS system for real-time analysis during races. Ballast adjustments are also incorporated to ensure compliance with BoP specifications.
The introduction of the 911 GT4 R signifies a new chapter for Porsche in GT4 racing, combining the legendary performance characteristics of the 911 with cutting-edge racing technology. This vehicle is designed to deliver a superior driving experience and competitive edge on the track, setting a new benchmark for customer race cars.
