Porsche revealed its latest enthusiast-level 911 at the 2023 Rennsport Reunion 7 at WeatherTech Raceway Laguna Seca in Monterey, California. Limited to only 77 examples, the Porsche 911 GT3 R rennsport is designed by Grant Larson and Thorsten Klein from the Style Porsche team.
The Porsche 911 GT3 R rennsport is based on the current 911 GT3 R of the 992 generation but with an extensively redesigned carbon skin. While the hood and roof remain faithful to the standard GT3 R, the rest of the body undergoes a radical transformation. The new Porsche 911 GT3 R rennsport sports a broad rear wing reminiscent of the legendary Brumos Porsche 935/77, aerodynamically optimized cooling air intakes and ducts framed by a side cowl, a cutting-edge system featuring three cameras integrated into the exterior of the vehicle and monitors in the cockpit takes the place of conventional exterior mirrors, a rear light bar with fine LED strips that illuminate the Porsche lettering, and an open rear fascia that exposes the technical components and exhaust system. The attention to detail extends to the 18-inch BBS wheels in an exclusive ‘racing’ design which are painted in Dark Silver Metallic as standard by Porsche Motorsport.
Inside the 911 GT3 R rennsport, the modifications continue with the two fender-mounted exterior cameras seamlessly blending into the interior, special graphics on the central display’s splash screen and a limited edition number on the instrument panel, ambient interior lighting that matches the color-adjustable main headlights, standard safety features mandated by FIA standards, and a roll cage design that limits it to a single-seat race car configuration.
The heart of the 911 GT3 R rennsport is a 4.2-liter six-cylinder boxer engine that revs up to 9,400 rpm. Without the constraints of motorsport series restrictions, this engine produces a power peak of up to 611 hp, translating to approximately 145 hp per liter. Power is delivered to the rear wheels through a sequential six-speed constant-mesh gearbox, controlled via steering wheel paddles and featuring gear ratios optimized for high-speed performance. It also features a state-of-the-art double wishbone suspension at the front and a multi-link suspension at the rear, five-way adjustable racing shock absorbers from KW with a blow-off function, and Michelin racing tires exclusively for GT3 R rennsport customers. The racing exhaust system, available in both unmuffled and quieter versions, contributes to an authentic engine sound.
Designed to run on E25 fuels, including bio-ethanol fuels and eFuel, this engine showcases Porsche’s commitment to sustainable performance. With their lower knocking tendency, these fuels allow for advanced ignition angles and increased compression in the six combustion chambers. Custom pistons and camshafts tailored for the GT3 R rennsport engine further enhance performance.
Weight-saving measures are evident throughout, with a lightweight aluminum monobloc racing brake system from AP, a new FT3.5 safety tank, and the elimination of the air conditioning system. Porsche aims for a curb weight of 2,734 lbs., resulting in a weight-to-power ratio of approximately 4.5 lbs/hp.
The Porsche 911 GT3 R rennsport carries a $1,046,000 price tag on top of transport, options, and applicable taxes. Porsche Motorsport will be making only 77 examples, and potential customers can register interest through the Porsche Motorsport website.
