Porsche Unveils 911 GT4 R for Global GT4 Racing
Porsche’s first 911-based GT4 race car delivers 520 PS performance and will debut in the 2027 motorsport season, strengthening its global customer racing programme
Porsche has officially unveiled the all-new 911 GT4 R, marking a major step forward in its global customer motorsport strategy. As the first GT4 race car based on the iconic 911 platform, the model is set to make its competitive debut in the 2027 racing season, expanding Porsche’s footprint in one of the fastest-growing categories in motorsport. Built on the technical foundation of the current 911 Cup car, which itself is derived from the road-going 911 GT3 (992.2), the 911 GT4 R replaces the previous Cayman-based GT4 Clubsport models. The new race car introduces increased power, wider track dimensions and upgraded motorsport electronics aimed at improving lap times, stability and overall drivability on track. Porsche says the 911 GT4 R blends the unmistakable DNA of the 911 with the proven GT4 racing concept, while offering customer teams a more performance-focused alternative within its motorsport lineup.
Cup-derived performance
At the heart of the 911 GT4 R is a naturally aspirated 4.0-litre flat-six boxer engine producing up to 382 kW (520 PS) and 470 Nm of torque. Power is delivered through a sequential six-speed dog gearbox with steering-wheel-mounted paddle shifters and a four-disc racing clutch.
In line with GT4 Balance of Performance (BoP) regulations, output can vary depending on the championship. Factory-installed air restrictors can reduce power to 316 kW (430 PS), ensuring parity across competing manufacturers.
The chassis has been specifically adapted for GT4 competition, featuring slightly narrower wheels with a production-style five-stud mounting system. Dual-adjustable dampers and multiple spring-rate options allow teams greater flexibility when setting up the car for different circuits.
Lightweight construction and race tech
The 911 GT4 R carries over key structural and aerodynamic elements from the 911 Cup, including a manually adjustable rear wing with 11 settings.
Lightweight construction remains a priority, with natural-fibre composite materials used across the doors, engine cover, aerodynamic components and sections of the cockpit. These materials help reduce weight while maintaining structural rigidity and durability under race conditions.
Inside, the cockpit is equipped with a 10.3-inch colour display, integrated data logging system, precision GPS and adjustable ballast to meet varying BoP weight requirements across championships.
Expanding Porsche’s GT4 racing presence
The GT4 category has grown rapidly since its introduction in the mid-2000s, offering production-based race cars with controlled costs and serving as a key stepping stone toward GT3 competition. Series such as ADAC GT4 Germany and the GT4 European Series have become important platforms for driver development.
Porsche currently ranks among the top manufacturers in global GT racing and has produced more than 1,500 Cayman-based GT4 race cars since entering the category in 2016.
With the introduction of the 911 GT4 R, Porsche is expanding its customer racing portfolio with a 911-based GT4 contender for the first time. The move reflects growing global demand for accessible yet high-performance race cars, while reinforcing the brand’s long-standing commitment to customer motorsport.
