Grand premiere of the new generation Porsche 911 GT3 R.

The new Porsche 911 GT3 R will be shown for the first time this year at the 24 Hours of Spa-Francorchamps. From the 2023 season, Porsche customer teams will be able to participate worldwide in motorsport events that comply with GT3 regulations. It is based on the current 992 generation of the 911. Compared to the previous model, the new 911 GT3 R features a more powerful engine delivering up to 416 kW (565 hp), more consistent aerodynamics and an optimized vehicle balance. .

Porsche presents the latest generation of the 911 GT3 R, its new customer race car. A contender for the global commitment of the GT3 series, it is based on the current generation 992 and will be able to compete with the opening of the 2023 season. Its development, which began in 2019, was focused on improving handling for professionals and “gentleman drivers”. , as well as a large power reserve according to the BoP (Balance of Performance) classification. Simplifying the use of this racing car by teams and optimizing operating costs were also major concerns. Porsche Motorsport is now offering the new 911 GT3 R for €511,000 plus VAT and country-specific options.

“The new 911 GT3 R is on a great path,” says Michael Dreiser, Director of Sales at Porsche Motorsport. “Since 2019, its predecessor has won just about everything that could be won in GT3 in four seasons. In particular, this was confirmed by the overall victories in the 24 Hours of Nürburgring and Spa-Francorchamps. In the 24 Hours of Daytona and 12 Hours of Sebring, our customers have won their class. Our customer team has an even bigger task ahead of them. After the inclusion of the GT3 category in the North American IMSA series, including for professionals, the FIA ​​World Endurance Championship (WEC) follows suit: from 2024, GT3 racing cars such as the new 911 GT3 R will be able to take part in races for the first time ” 24 hours of Le Mans.

“Thanks to the huge success of the previous model, we have been successful. The bar is therefore set very high for its successor,” emphasizes 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, because this advantage is quickly offset by the classification in the BoP performance windows. For us, the main thing was to allow our customers to go faster in this racing car for longer. Consistency is key. That’s why we mainly focused on improving handling. The result: a new 4.2-litre engine with a wider operating rev range, more stable and consistent aerodynamics and less stressed rear tires, which can thus show their full potential more regularly. »

One of the centerpieces of the new race car is its close-to-production engine based on the 992 generation 911. Like the previous model, it is a water-cooled six-cylinder boxer engine equipped with four valves and direct injection gasoline. The novelty lies primarily in the engine size: like the 911 RSR, the new 911 GT3 R has been reduced from 3997 to 4194 cm3.3, an increase of five percent. Thus, the peak power of the engine reaches approximately 416 kW (565 hp). But above all, Porsche has optimized the torque and power curve across the entire rev range. The new 4.2-litre six-cylinder engine is therefore particularly suitable for “gentleman drivers”.

This high-revving six-cylinder engine, which is still easily managed without turbocharging, is conventionally located at the rear, where it has a positive effect on traction and braking. It has been tilted forward 5.5 degrees to give more freedom to the floor diffuser. Ancillary components such as the alternator and A/C compressor have been moved a good meter forward and down to free space in front of the engine and gearbox. This modification improves the weight balance of the 911 GT3 R. The six-speed sequential cam transmission is inherited from the current 911 GT3 Cup. Paddles on the steering wheel control an electronic system that activates the gear selector drums, allowing particularly fast and precise gear changes.

The chassis of the new 911 GT3 R has been redesigned down to the smallest detail, making it easier to drive, improve steering precision, reduce rear tire wear and reduce the time it takes to make adjustments. Many components and solutions from the 911 RSR were used for this. On the front axle, a modern double wishbone system provides wheel control. The rear axle has a multi-link design. The advanced KW competition dampers can be adjusted to five positions. Gaskets are available for reconfiguration. These target discs allow fast and precise alignment without having to re-check the very time consuming geometry of the chassis.

The optimized location of the central pivot points of the front axle makes room for the aerodynamic “Race Underfloor” concept. As with the 911 RSR, thanks to its higher lower section, it allows for a smoother flow of the rear diffuser and thus reduces the car’s pitch sensitivity, i.e. its response to a reduction in front ride height that can occur when braking due to compression damping. The rear wheels of the 911 GT3 R have been moved slightly back towards the rear of the car, increasing the wheelbase from 2459 mm to 2507 mm. This modification also makes it possible to reduce the weight of the rear tires and therefore ensure their continued performance in competition after long runs.

In addition to the one-piece aluminum racing brake calipers, the brake discs of the new 911 GT3 R are now also manufactured by specialist company AP. The steel front discs are ventilated and slotted. With a diameter of 390 mm, they are surrounded by six pistons. The rear is fitted with 370mm discs and four-piston brakes. A finely tuned software application for fifth generation ABS racing system reduces tire and brake wear. Porsche’s traction control system has also been improved.

After the 911 GT3 Cup, the new 911 GT3 R is the second racing car developed by Porsche Motorsport based on the current generation of the 992. Its lightweight, intelligent composite aluminum and steel body is based on that of the series, but has been extensively modified for competition. Almost all body parts, including the front and engine cover, doors, sides, rear spoiler and roof, are made of lightweight carbon fiber. The material used for the wings is aramid.

In the new 911 GT3 R, functionality is everything. The fact remains that in Porsche Style, Grant Larson has once again succeeded in achieving particularly beautiful and harmonious shapes. They highlight the 911’s genetic heritage, combining it with sophisticated efficiency. Aerodynamics is the clearest confirmation of this. It combines for the first time a raised underfloor in front of the front axle with a fully enclosed underfloor and rear diffuser. Downforce is improved without a significant increase in drag. The rear fender has gooseneck suspension. This provides an even smoother bottom flow and thus improves the aerodynamic efficiency of the element.

When it comes to safety, the new 911 GT3 R also takes an uncompromising approach. The seat has moved closer to the center of the car. In this way, Porsche has been able to optimally adapt the seat, which is now more ergonomic, to the improved safety cell and side protection in accordance with FIA regulations. As on the previous model, adaptation to the pilot is carried out by longitudinal adjustment of the steering wheel and pedals. Porsche has also revised the six-point seat belt with magnifying glass: thanks to special ramps, its tongues are now even faster to insert into the lock, which can save a second of time in the pit stop when changing drivers. The steering wheel design improves on the previous model. But it also brings together elements that have proven themselves in the current 911 GT3 Cup and 911 RSR. For example, the 10.3-inch screen is taken from the GT3 Cup and the multi-switch concept is taken from the class-winning 911 RSR at Le Mans.

The powerful LED headlights of the 911 GT3 R use the so-called collimator technology that Porsche has developed for the new LMDh 963 prototype, among other things. They work like a magnifying glass, but in reverse. They provide a particularly wide illumination of the road surface and are clearly superior to the previous model, which has so far been considered the best of all.
