Our auto paparazzi say Porsche’s Nürburgring 911 GT3 RS prototype is something else. The test vehicle sounded turbocharged, unlike the naturally aspirated flat-six powering the most extreme 992-gen sports car. The intercoolers may have adjusted those side air intakes.
The rear apron’s dual exhaust tips are false. The actual ones are left and right between the diffuser and bumper. The 911 GT2 RS won’t debut until late 2025, thus this is likely a test mule. Future prototypes may undergo more alterations to distinguish the flagship from the GT3 RS.

Porsche presented the 911 GT2 RS Clubsport Evo race vehicle based on the 991 model yesterday, and the next-generation road car is already being tested. It’s supposed to have over 700 horsepower by converting the 911 Turbo S’ powertrain to incorporate an electric motor for an ultra-powerful hybrid arrangement.

Autocar revealed in early March that the 911 GT2 RS will have the flat-six 3.8-liter, twin-turbo engine and a mild-hybrid system from the 963 LMDh. The British publication noted a “significant increase in torque” over the Turbo S’ 590 pound-feet (800 Newton-meters). The ultimate 992 will weigh 220 pounds (100 kilograms) more than the Turbo S, despite its extra hardware.
The upcoming 911 GT2 RS may include a gearbox-mounted electric motor and a battery pack beneath the rear seats. A supercar with an electric driving mode will reportedly distribute weight 39:61 front/rear. The powertrain is “even more advanced” than the 963 LMDh’s, and a Weissach Package might reduce the fat.
As usual, the GT2 RS will be based on the facelifted 911, which has been observed in testing. An entirely electric derivative won’t happen before 2030.
