You can now see the all-new 2027 911 GT4 R in the flesh, as Porsche has removed the covers on its most recent customer race car for GT4 competition. It is the next step in the evolution of a machine built to be raced in GT4 series across the globe.
Taking its cues from the revised 992.2 911 Cup car, this new GT4 R has been given more power and better aerodynamics along with a raft of upgrades for the driver’s benefit, whether he or she is an amateur or a pro. Reliability has been enhanced as well, in keeping with Porsche Motorsport’s tradition of supporting its customers.
The heart of the matter is a 4.0-liter flat-six boxer that is naturally aspirated and good for 513 hp and 346 pound-feet of torque (subject to the BoP rules of the particular series).
There is dry-sump lubrication here, a reworked intake with dual resonance flaps and a race exhaust with a catalytic converter to satisfy the regulations. To get that power to the rear wheels there is a six-speed sequential dog-ring box with electronic paddles, active oil cooling and a mechanical limited-slip differential. For endurance work, Porsche has fitted a single-mass flywheel and a clutch of the race-spec variety for quicker response and longevity.
Weighing in at some 3,340 lbs to stay within GT4 limits, the 2027 model has a body that has been rethought for lightness. The aluminum-steel composite structure makes liberal use of NFRP panels.
Up front you will notice a larger splitter and a wider bumper; underneath the body has been optimized with integrated cooling ducts. At the back, an adjustable swan-neck wing gives teams 11 different settings to dial in the downforce for whatever circuit they are on.
Porsche has put together a cockpit with endurance racing in mind. The multifunction carbon-fiber wheel has your traction control, ABS and paddle shifter controls at hand, plus illuminated buttons. A new touch panel with physical click feedback lets you get to the vehicle settings.
The FIA-approved bucket seat is fully adjustable and has interchangeable padding for the comfort of the driver. You will also find an air-jack system, a 110-liter FT3 fuel cell and all the requisite FIA safety gear, not to mention better ventilation.
The chassis has seen some major changes. The double-wishbone front and multi-link rear suspension are now fully adjustable, as are the dampers and anti-roll bars on the forged components. Porsche claims the new setup is more consistent and precise over the course of a long race.
When it comes time to stop, there are 380-mm ventilated steel rotors and monobloc calipers (six-piston up front, four in the rear). With Bosch Gen 5 Race ABS and adjustable bias as standard, drivers should have no trouble with confidence under hard braking.
This is a car for the private teams doing sprint and endurance championships around the world. As such, it comes with everything you need: an LED lighting system with rain and stall-warning lights, tire monitoring, a drivetrain warm-up mode, GPS lap timing and Porsche’s data logger.
As for when you can get one and what it will cost, Porsche has put no numbers on the table yet. But expect to see the 911 GT4 R on track in GT4 series before the 2027 season gets underway. With the added power and proven engineering, it seems set to give the brand another successful run in customer motorsport.
