Porsche unveils the next generation of its GT3 race car

On the heels of the 992 generation of the 911 road car and the 992-based GT3 Cup, Porsche has now revealed the next generation of the 911 GT3 R at TotalEnergies 24 Hours Spa. The new challenger to the GT3 series around the world, including the IMSA Weathertec Sportscar Championship and the SRO Fanatec GT World Challenge Americas, is based on the current 992 generation of the 911 platform 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, with a priority to further improve driving ability for drivers with different skills, noting that many GT3-based championships are built around gentleman drivers. as well as exploiting large display stores for various balancing of performance classifications. Another focus was on streamlining race car operations for teams and reducing running costs. Porsche Motorsport now offers the new 911 GT3 R to North American customers at a price of $567,210 plus optional extras. In the United States and Canada, the new racer is available only through Porsche Motorsport North America.

“In North America, the GT3 is the top class of GT racing, as it will soon be around the world,” commented Volker Holzmeyer, President and CEO of Porsche Motorsport North America. “This made the new generation of the 911 GT3 R particularly important to our market. Its evolution, which includes not only the lessons learned from the previous generation GT3 R, but also the GT3 Cup one-make car as well as the 911 RSR, has made this car very attractive to our customer teams. Ease of use is remarkably important to the wide range of drivers competing here and this was the focus of the 992 911 GT3 R type. We’ve already had a great deal of interest in the car, and we look forward to seeing it turn its first wheel. Here soon.”

After the GT3 class was announced as a professional category, GTD PRO, in the IMSA WeatherTech Sportscar Championship, the FIA ​​World Endurance Championship will follow suit. Starting in 2024, GT3 racing cars such as the new 911 GT3 R will be eligible to participate in the 24 Hours of Le Mans for the first time, adding to the dozens of series around the world where GT3 cars are eligible to compete.

“We hit the bull’s eye with the hugely successful predecessor. Accordingly, the bar is high for its successor,” says Sebastian Golz, 911 GT3 R project manager at Porsche Motorsport. “Our job is to make the new 911 GT3 R even faster. Less was about – classification within the performance window set by the BoP quickly cancels out this advantage. For us, it was primarily about being able to drive the car faster for longer periods of time by our customers. This requires durability and that’s why we focused primarily on better accessibility. This is reflected in the new 4.2-litre engine’s wider usable rev band, more stable and sustained aerodynamics and less load on the rear tyres, which allows their ability to last longer.

At the core of the new racing car is a nearly standard engine based on the 992-generation 911 powerplant. Like the previous model, it is a water-cooled flat-six engine with four-valve technology and direct fuel injection. The main new development is displacement. Like the 911 RSR, the new 911 GT3 R has seen a 5 per cent increase in capacity from 3,997 to 4,194 cc. This has increased the peak output of the normally aspirated engine to around 565hp. However, more importantly, Porsche has optimized the torque and power curve across the rev range. As a result, the new 4.2-liter six-cylinder is better suited for a wider range of driver experiences.

The engine has been tilted forward by 5.5 degrees, making more room for the underbody diffuser. Auxiliary components such as the alternator and air conditioning compressor were moved significantly back and forth in a space in front of the engine and gearbox, which has a positive effect on the 911 GT3 R’s weight balance. The sequential six-speed competition-mesh gearbox is derived from the existing 911 GT3 Cup race car. Shift pedals control an electronic shift drum actuator that enables particularly rapid and precise gear changes.

The suspension of the new 911 GT3 R allows for more precise steering, contributes to a reduction in wear on the rear tires and reduces the time spent on set-up changes. Set-up modifications are performed with shims, enabling precise adjustments without the need for the time-consuming re-alignment of the suspension afterwards.

The optimized position of the central pivot points on the front axle frees up space for the aerodynamic “race underfloor” concept that allows a clean flow of air to the rear diffuser and reduces the pitch sensitivity of a racing car

In the cockpit, the seat has moved closer to the center of the car. This enabled Porsche to better adapt the better roll cage and more ergonomic seat positions to the newly developed FIA side impact protection mandate. Like the predecessor, the steering wheel and pedals can be adjusted longitudinally to suit the driver while maintaining a fixed seat mount.

Porsche experts took another closer look at the six-point harness. The tongue now slides even faster into the clasp via special ramps – saving about a second during pit stops for driver changes. The steering wheel incorporates elements that have proven themselves in the latest generation 911 GT3 Cup and 911 RSR race cars. For example, the 10.3-inch display comes from the successful One-Make Cup Racer, with the multi-switch concept adopted by the winner of the Le Mans class.

Like the new Porsche 963 LMDH car, the 992 911 GT3 R is expected to make its North American competition debut at the 2023 Rolex 24 at Daytona.
