On the heels of the 992nd generation 911 road car and the 992-based GT3 Cup, Porsche has now revealed the next generation of the 911 GT3 RV in the 24 Hours Total Energy Spa. The new Challenge GT3 World Series, including the IMSA WeatherTech SportsCar Championship and SRO Fanatec GT World Challenge America, are based on the current generation 992 platform 911 and will be ready to race at the start of the 2023 season.
Porsche Motorsport began developing the next generation of its GT3 racer in 2019, prioritizing further improving the drivability of drivers with different skills, given that many GT3-based championships are built around noble drivers, as well as benefiting from greater performance reserves for various scale performance ratings. . Another focus was on simplifying race car handling for the teams and reducing operating costs. Porsche Motorsport is now offering the new 911 GT3 R to North American customers, priced at $567,210 and optional extras. In the US and Canada, the new racer is only available through Porsche Motorsport North America.
“In North America, the GT3 is the premier class in GT racing, as it will soon appear worldwide,” commented Volker Holzmeyer, President and CEO of Porsche Motorsport North America. This is why the new generation of the 911 GT3R is particularly important for our market. Its development, which includes not only lessons learned from the previous generation GT3 R but also from the one-model GT3 Cup as well as the 911 RSR, has made this vehicle extremely attractive to our customer teams. Driveability is remarkably important to the wide range of drivers we have competitors for here and that was the focus on the 992 911 GT3 R. We’ve already had a lot of interest in the car, and look forward to seeing it spin its first wheel. here soon.”
After announcing the GT3 class as a professional class, GTD PRO, in the IMSA WeatherTech SportsCar Championship, the FIA World Endurance Championship will follow suit. From 2024, GT3 racing cars such as the new 911 GT3 R will be eligible to compete in the 24 Hours of Le Mans for the first time, as well as dozens of series around the world where GT3 cars are eligible to compete.
“We hit the bull’s-eye with our massively successful predecessor. Accordingly, the benchmark for its successor is high,” says Sebastian Jules, 911 GT3 R Project Manager at Porsche Motorsport. “Our job wasn’t about making the new 911 GT3R faster – rating within the performance windows defined by BoP quickly eliminates that advantage. For us, it was primarily about our customers being able to drive faster for longer. The first is on improved drivability. This is reflected in the wider usable rev range of the new 4.2-liter engine, more consistent and stable aerodynamics, and lower loads on the rear tires, allowing it to last longer.”
At the heart of the new race car is a semi-standard engine based on the 992nd generation 911 engine. Like the previous model, it is a water-cooled flat-six engine with four-valve technology and direct fuel injection. A major new development is Offset. Like the 911 RSR, the new 911 GT3R’s capacity has increased by five percent, from 3,997 to 4,194 cc. This increased the output of the naturally aspirated engine to around 565 hp. But most importantly, Porsche has improved the torque and power curve across the entire rev range. Thus, the new 4.2-liter six-cylinder engine is best suited to a wider range of driver experience.
The engine is tilted forward 5.5 degrees, providing more room for the lower diffuser. Additional components such as the alternator and air conditioning compressor have been moved significantly forward and downward in space in front of the engine and gearbox, which has a positive effect on the 911 GT3R’s weight balance. A mesh gearbox is derived from the current 911 GT3 Cup race car. The paddles control the electronic transmission drum actuator which enables fast and precise gear changes.
The suspension system on the new 911 GT3R allows for more precise steering, contributes to reduced rear tire wear and reduces time spent on setting changes. Fitment adjustments are made with shims, allowing precise adjustments without the time-consuming realignment of the suspension.
The optimal location of the center axle points on the front axle makes room for the aerodynamic “race ground” concept that allows clean air flow to the rear diffuser and reduces the racing car’s tilt sensitivity
In the cockpit, the seat came closer to the center of the car. This enabled Porsche to optimally adapt the ergonomic seat position with an improved rolling cage and newly developed FIA side-impact protection mandates. As in its predecessor, the steering wheel and pedals can be adjusted longitudinally to suit the driver while keeping the seat fixed.
Porsche specialists took another closer look at the six-point belt. The tabs now slide faster into the clamp through special ramps – saving about a second while pit stops for a driver change. The steering wheel incorporates elements that are proven in the latest generation of the 911 GT3 Cup and 911 RSR racing cars. The 10.3-inch screen, for example, comes from the successful one-man-made Trophy rider, with a multi-key concept approved by the Le Mans class winner.
Like the new Porsche 963 LMDh, the 992 911 GT3 R is expected to make its North American competition debut at the 2023 Rolex 24 in Daytona.
