The updated 911 GT3 R is based on the latest 992 generation 911 and complies with the global GT3 regulations. It features a larger engine with up to 565 horsepower, more consistent aerodynamic performance and optimized vehicle balance. Porsche customer teams will be able to race the new 911 in the IMSA WeatherTech SportsCar Championship starting in the 2023 season.

“In North America, GT3 is the highest category of GT racing, as it is worldwide,” said Volker Holzmeier, President and CEO of Porsche Motorsport North America. “This has made the new generation 911 GT3 R especially important for our market. His development, which includes not only lessons learned from the previous GT3 R generation but also from the experience of the GT3 Cup monolithic car as well as the 911 RSR, has made this car very attractive to our customer teams.”

Development of the new 911 GT3 R began in 2019. Priority was given to further improving handling for drivers with different skill sets, as well as using more performance headroom across different Balance of Performance (BoP) classifications. Another focus was on optimizing vehicle handling for teams and reducing operating costs. Porsche Motorsport is offering the new 911 GT3 R to North American buyers for $567,210 with optional extras. In the US and Canada, the new driver is available through Porsche Motorsport North America.

“Drivability is extremely important to the wide range of drivers we compete against here, and that was the focus of the 992 911 GT3 R,” said Holzmeyer. “We already have a huge interest in the car and look forward to seeing it turn its first wheel here soon.”

After the GT3 class was declared a professional category in the WeatherTech championship, the FIA ​​World Endurance Championship announced that it would follow suit. Starting in 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.

The new race car is powered by an almost standard Porsche 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. Engine displacement increased by 5 percent to 4.2 liters. Porsche has optimized the torque and power curve across the entire rev range, making the engine better suited to a wider range of driver capabilities. The six-cylinder engine is naturally aspirated and takes the classic rear position for more traction and braking. It was tilted forward 5.5 degrees, making room for a diffuser underneath.

The sequential six-speed gearbox with gearbox is borrowed from the current 911 GT3 Cup race car. The paddle shifters control the electronic shift drum drive, which ensures particularly fast and precise gear changes.

On the front axle, the wheels are steered by a modern two-lever layout. The rear axle has a multi-link design. The optimized positioning of the central pivots on the front axle makes room for the aerodynamic “racing underground” concept. As with the 911 RSR, this raised underbody provides clean airflow to the rear diffuser and reduces pitch sensitivity. The rear wheels have been moved further back, increasing the wheelbase from 8.0 feet to 8.22 feet. It also reduces stress on the rear tires and improves tire performance stability on long journeys.

The new 911 GT3 R is the second Porsche Motorsport racing car built on the basis of the current 992 911 after the 911 GT3 Cup. Its lightweight aluminium-steel composite body resembles the production model, albeit with significant modifications for use in the 911 GT3 R. Nearly all body panels are made from lightweight carbon fiber, including front and rear covers, doors, and side panels. , rear fender and roof. Wheel arches are made of aramid fibres.

The high-performance LED headlights of the 911 GT3 R are based on the collimator technology that Porsche has developed, among other things, for the new IMSA GTP prototype. This device works like a magnifying glass, but in reverse. It illuminates a particularly large area of ​​the race track and represents a significant improvement over the previous model, which was considered the leader in its class.

“We hit the bull’s-eye with a hugely successful predecessor. Accordingly, the bar is set high for its successor,” said Sebastian Goltz, Project Manager for the 911 GT3 R at Porsche Motorsport. “Our goal was not so much to make the new 911 GT3 R even faster – classifying within the performance windows set by BoP quickly cancels out this advantage. For us, it was above all that our customers could drive the race car faster and longer. This requires durability, so we focused mainly on improving handling. This is reflected in the wider rev range of the new 4.2-litre engine, more stable and consistent aerodynamics and less stress on the rear tires to extend their potential.”
