Porsche has unveiled the 911 Challenge, a new entry-level customer race car based on the 911 GT3 road car and eligible for one-make series worldwide beginning with the 2027 season. Porsche Motorsport North America is offering the car to 2027 Porsche one-make entrants at $275,000 including import and delivery to the United States, and with the addition of the Challenge, every currently produced Porsche GT race car is now based on the 911. In the U.S., the new model can compete in the Porsche Sprint and Endurance Challenge North America by Yokohama, the Porsche Sprint Trophy Porsche Club of America by Yokohama, and the recently announced Porsche Sprint Trophy Porsche Owners Club, with full-season entrants receiving priority on allocations. Porsche expects the car to become available for track days, testing, and private motorsport use later in 2027.
Unlike the 911 Cup revealed in August 2025, the Challenge carries over a significant amount of production GT3 technology, including the aerodynamics, the seven-speed PDK gearbox with automatic or paddle-operated manual shifting, the GT3 RS steering wheel with added racing-specific functions, and air conditioning. Adjustable ABS, traction control, and Electronic Stability Control are included to ease the transition into motorsport, along with multi-stage adjustable Porsche Torque Vectoring Plus. The 4.0-liter flat-six is largely derived from the production GT3 and produces 508 hp (379 kW) at 8,500 rpm on its way to the same 9,000 rpm redline as the road car, breathing through a modified muffler that retains a catalytic converter but drops the particulate filter.
The chassis draws on racing components shared with the 911 Cup, including shock absorbers with a motorsport-specific characteristic curve and an anti-roll bar adjustable in three positions. Racing slicks mount to 18-inch wheels via the standard five-bolt pattern, following the approach of the recently unveiled 911 GT4 R, and the steel brake discs measure 15 inches (380 mm) front and rear, matching the hardware used in both the GT4 R and the Cup. The body dimensions and key exterior components are identical to the GT3, with an integrated three-jack air-jack system, an FIA-certified rain light, quick-release hood fasteners, and a rear wing mechanically adjustable to four angles.
Inside, all sound deadening, carpets, and trim are removed in favor of a welded-in roll cage, an adjustable racing bucket seat with a six-point harness, a fire-extinguishing system, and a 29-gallon (110 liter) FIA FT3 fuel cell. The 911 Challenge is not street legal. As the entry point to Porsche’s 911-based race car hierarchy, it succeeds the original Cayman GT4 Clubsport and the 718 Cayman GT4 RS Clubsport, sitting below the 911 GT4 R for international GT4 competition, the 911 Cup for the Porsche Mobil 1 Supercup and Carrera Cup series, and the 911 GT3 R for FIA GT3 racing.
