Porsche Motorsport has officially unveiled and released all the technical details of its new GT3 car, which will enter global competition with customer teams next year.

The latest Porsche 911 GT3 R will be based on the 992 generation of the road-going Porsche 911. According to the German manufacturer, the main focal points of the new vehicle are “more power, sophisticated aerodynamics and optimized balance”.

Porsche last month unveiled the first images of its Type 922 GT3 car from April testing at Spa-Francorchamps, while publicly unveiling the car at this weekend’s TotalEnergies 24 Hours of Spa.

The new 911 GT3 R features a larger engine than its 2019 predecessor, with the 4.2-litre displacement exceeding the 4-litre of the Type-991.2, now in its final season.

This enabled the displacement of the engine to be increased by 5 percent, with which Porsche intends to achieve its goal of “opening up larger reserves for different BoP classifications”.

Porsche says it has tweaked the torque and power curves across the rev range to make the powerplant “more suitable” for amateur drivers.

Like the 2019 model, which won several major endurance races including the 24 Hours of Spa, the Nürburgring and Daytona, the new car’s engine is a rear-mounted, water-cooled, flat-six with four-valve technology and direct fuel injection.

However, the engine was tilted forward by 5.5 degrees to create more space for the diffuser. Also, the alternator and air conditioning compressor have been moved forward and down the car to sit in front of the engine and transmission.

The sequential six-speed gearbox comes from the current 911 GT3 Cup, which also belongs to the 992 generation.

“We hit the mark with the enormously successful predecessor,” says Porsche 911 GT3 R project manager Sebastian Golz.

“Accordingly, the bar for succession is high. Our task was not so much to make the new 911 GT3 R even faster – the classification in the BoP performance window quickly negated this advantage.

“The main thing for us was that our customers could drive the racing car faster for longer.

“That requires durability and that’s why we focused primarily on improved drivability.

“This is reflected in a wider usable rev range of the new 4.2-liter engine, more stable and constant aerodynamics and less stress on the rear tires, which means that their potential can be used longer.”

The 2023 Porsche 911 GT3 R also includes “modified” chassis components designed for more precise steering and reduced tire wear. The front axle has a double wishbone arrangement, while the rear axle has a multi-link construction like the 2019 product.

The wheelbase increases slightly from 2,459 to 2,507 mm, which is due to the rear wheels being set further back.

The new vehicle’s aerodynamic profile features a raised underbody and rear diffuser, while Porsche introduced a “gooseneck” mount for the rear wing. Similar rear wing layouts were added to this year’s Evo II version of the Audi R8 LMS GT3 and next year’s Ferrari 296 GT3.

In the cockpit, the driver’s position has been moved closer to the center for better ergonomics within the roll cage and newly developed FIA side impact protection.

The steering wheel incorporates elements derived from other Porsche racing cars, such as the 10.3-inch display from the 911 GT3 Cup and the clustered multi-switch concept found in the GTE-spec 911 RSR-19.

Porsche customer teams can field the new GT3 car in a variety of series using the global formula, including the FIA ​​World Endurance Championship and the 24 Hours of Le Mans, which will accept GT3-based machines from 2024.

“The new 911 GT3 R is following in big footsteps,” says Michael Dreiser, Head of Sales at Porsche Motorsport.

“His predecessor has won almost everything there is to win in the GT3 scene in four seasons since 2019.

“Outstanding successes include overall victories in the 24-hour races at the Nürburgring and also here in Spa-Francorchamps.

“In our customers’ operations, the predecessor achieved class victories at the 24 Hours of Daytona and the 12 Hours of Sebring. In addition, the car has clinched numerous titles in international GT3 sprint and endurance championships.”

Porsche has listed a price of €511,000 ($521,188) plus VAT for its 2023 competitor, which is expected to make its race debut in non-homologated trim later this year.
