2023 Porsche 911 GT3 R benefits from more power and more downforce
Power for the GT3 R comes from a flat-six engine whose displacement was increased by 5% to 4.2 liters. It develops about 565 horsepower, and it spins the rear wheels via a six-speed sequential gearbox linked to a pair of shift paddles. The engine remains rear-mounted, but it's tilted forward by 5.5 degrees to clear up more space for the rear diffuser.
Mechanics will be able to make setup modifications to the suspension using shims that eliminate the need to spend time re-aligning the system after it's been adjusted. The suspension changes made to the GT3 R also reduce tire wear, which helps bring down racing costs. Porsche notes that it moved the rear wheels further back to increase the wheelbase and reduce load on the back tires, and theincludes six-piston front calipers that grip massive, 15.
Carbon fiber body panels and an aluminum-steel composite body help keep weight in check, though Porsche hasn't published how much the 911 GT3 R weighs. Visually, the GT3 R is characterized by a redesignedand a huge rear wing mounted on a set of swan necks. There's more to it than meets the eye, though: The part of the underbody that's ahead of the front axle is elevated to improve the flow of air to the rear diffuser.
Inside, Porsche moved the driver's seat closer to the center of the car in the name of ergonomics. The seat is fixed, though the steering wheel and the pedals can be adjusted, and special ramps save about a second per pit stop by making the six-point harness faster to fasten.GT3 R is on sale now through Porsche Motorsport North America. It will make its competition debut at the 2023 edition of the Daytona 24 scheduled to take place in January 2023.
