Porsche has revealed its latest 911 racing car, intended as the first step on the customer motorsport ladder.
The new 911 Challenge acts as the replacement for the 718 Cayman GT4 Clubsport and GT4 RS Clubsport models.
In the UK, this will make the 911 Challenge the entry point for the Porsche Motorsport Pyramid from 2027 onwards.
In order to make the 911 Challenge accessible to those who are racing for the first time, the new model borrows heavily from the contemporary road-going Porsche 911 GT3.
From a PDK dual-clutch auto transmission, to a host of driver aids such as traction control and electronic stability control, the 911 Challenge should prove relatively accessible for novice GT racers.
Porsche 911 Challenge heads to the grid
Powering the 911 Challenge is a familiar engine: the 4.0-litre flat-six found in the latest 992.2-generation 911 GT3.
Compared to the 911 GT3, the Challenge gets a slight boost in power to 515hp at 8,500rpm, plus a modified exhaust system that does without a particulate filter.
The seven-speed PDK transmission can be used in either manual mode, using the steering wheel-mounted paddles, or left to shift gears automatically.
Multi-stage adjustable Porsche Torque Vectoring Plus (PTV+) comes as standard, also helping drivers to deploy power more easily and effectively.
Race-proven technology included
Chassis components are taken from the Porsche 911 Cup car, including shock absorbers with bespoke motorsport tuning. The anti-roll bar can be adjusted through three different settings, too.
Racing slick tyres are fitted to 18-inch wheels, although these are mounted using a standard five-hole hub rather than a centre-lock setup – similar to the 911 GT4 R.
The 911 GT4 R also donates its braking system, with 380mm steel discs found on both the front and rear axles.
Bodywork changes include the addition of an FIA-certified rain light for the back bumper, while the tail spoiler can be manually adjusted through four different angles.
Continuing the Porsche Motorsport story
The interior of the 911 Challenge retains the same steering wheel and dashboard as the production GT3, but with the sound-deadening materials, carpets and trim removed.
Porsche Motorsport has also installed a welded-in roll cage, a racing bucket seat with a six-point harness and a 110-litre fuel tank.
Michael Dreiser, head of sales at Porsche Motorsport said: “The 911 Challenge brings the driving experience of the road-legal 911 GT3 into customer motorsport more directly than ever before.
“Drivers can get to grips with it without a long learning curve and can complete their first kilometres on the racetrack in a familiar vehicle design. We are following a principle here that dates back to the 1960s: our customers receive a race-ready car complete with motorsport safety technology, data acquisition, spare parts support and technical documentation.”
Available to order from 25 September 2026, the 911 Challenge will be eligible to compete in the 2027 Porsche Carwow Sprint Challenge GB championship.
