2023 Porsche 911 GT3 R’s Engine Is Bigger, More Powerful, and Tilted (Really)
Just in time to race the 2023 season, as well as the new FIA World Endurance Championship GT3 class at the 24 Hours of Le Mans from 2024, the all-new 2023 Porsche 911 GT3 R customer race car has been unveiled. . Porsche has lifted the leaf on the new 911 GT3 R a month before its street counterpart, the recently teased 911 GT3 RS road car. It’s not cheap, however, with a starting price of over half a million dollars.
In development since 2019, the new GT3 R based on the 992 generation 911 brings significant improvements to its engine. It’s still a naturally aspirated, water-cooled flat-six with direct injection, but capacity has been increased by 5% from 3997cc to 4194cc, making it now a 4-engine. .2 liters. The engine has also been tilted forward five degrees to make room for the underbody diffuser – yes, the whole engine – and the air conditioning compressor and alternator have been moved forward and lower. , improving weight balance. The engine is rated at 565 horsepower, a 65 hp increase over the outgoing racer, and the engine is still mated to a six-speed sequential gearbox with paddle shifters.
“We hit the bull’s eye with the wildly successful predecessor. Therefore, the bar for its successor is high,” stresses Sebastian Golz, 911 GT3 R project manager at Porsche Motorsport. “Our task was less to make the new 911 GT3 R even faster – ranking within the performance windows set by the BoP quickly negates this advantage. For us it was mainly about our customers being able to drive the race car faster and longer.” This requires durability and that’s why we focused mainly on improving handling. This is reflected in the new 4.2-litre engine’s wider usable rev range, more stable and consistent aerodynamics and lower rear tire loads, allowing their potential to last longer.
The suspension has also been tuned. A double-wishbone setup backs the front axle with a multi-link setup at the rear, now with upgraded adjustable KW shocks. Porsche says its suspension tweaks, some of which come from the 911 RSR, allow for more precise steering, improve set-up time and help reduce tire wear, all in an effort to make it easier to pilot for client teams. The wheelbase of the 911 R has also been lengthened by 2.64 inches by moving the rear wheels back. For aero, a raised underbody in front of the front axle works with the smooth underbody and rear diffuser for better airflow and increased downforce.
The body is based on the same lightweight aluminum-steel composite design as the production car, although almost all of the 911 R’s body panels are carbon fiber, including the bonnet, bonnet, fender rear, roof panel, side panels, and doors, with aramid fiber wheel arches (similar to fiberglass). For braking, ventilated and slotted steel 15.35-inch-diameter six-piston front discs are sourced from specialist company AP, joining 14.56-inch four-piston discs at the rear, with monobloc aluminum calipers. aluminum. Porsche says the car’s updated fifth-generation ABS software helps reduce tire and brake wear, with an upgrade to the traction control system as well.
Inside, Porsche has moved the driver’s seat inboard, closer to the center of the car, to improve the geometry of the roll bar and comply with new regulations side impact protection mandates. FIA. Driver controls, including steering wheel and pedals, can be adjusted without moving the fixed seat. To improve driver change times, special ramps have been added to the six-point harness clasps, which Porsche says should cut pit stop driver exchanges by about a second. The steering wheel’s multi-switch setup is that of the 911 RSR Le Mans, and the 10.3-inch driver display comes from the 911 GT3 Cup race car.
The new 911 GT3 R is available in North America for $567,210, not including optional extras.
