Porsche officially launches next year’s new GT3 contender with enlarged flat-six engine…

Porsche Motorsport has officially launched and released full technical details of its new GT3 car that will enter global competition with customer teams next year.

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

Porsche revealed the first images of its Type-922 GT3 car last month from an April test at Spa-Francorchamps, while this weekend it presented the car publicly for the first time at the TotalEnergies 24 Hours of Spa.

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

This has resulted in a 5 percent increase in the engine’s capacity, which Porsche hopes will fulfill its target of “tapping into larger reserves for different BoP classifications.”

Porsche says that it has optimized the torque and power curves across the entire rev range to make the power unit “better suited” to amateur drivers.

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

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

The sequential six-speed gearbox derives from the current 911 GT3 Cup car, which is also part of the 992 generation.

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

“Accordingly, the bar for its successor is high. Our task was less about making the new 911 GT3 R even faster – the classification within performance windows set by the BoP quickly cancels out this advantage.

“For us, it was primarily about our customers being able to drive the racing car fast for longer.

“This requires durability and that’s why we focused predominantly on improved driveability.

“This is reflected in the new 4.2-liter engine’s broader usable rev band, more stable and constant aerodynamics and lower loads on the rear tires, which allow their potential to last longer.”

The 2023 Porsche 911 GT3 R also includes “modified” suspension components designed for more precise steering and reduced tire wear. The front axle has a double-wishbone layout while the rear axle has a multi-link design, as is the case on the 2019 product.

There has been a slight wheelbase increase from 2,459 to 2,507 mm courtesy of the rear wheels being moved further back.

The new vehicle’s aerodynamic profile features an elevated underbody and a rear diffuser, while Porsche has introduced a ‘swan-neck’ mount for the rear wing. Similar rear wing layouts have been added to this year’s Evo II version of the Audi R8 LMS GT3 and next year’s Ferrari 296 GT3.

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

The steering wheel includes 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 will be able to run the new GT3 car in a wide range of series that use the global formula, including the FIA World Endurance Championship and the 24 Hours of Le Mans which are accepting GT3-based machinery from 2024.

“The new 911 GT3 R has big shoes to fill,” commented Michael Dreiser, sales director at Porsche Motorsport.

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

“Its stand-out successes include overall victories at the 24-hour races at the Nürburgring and also here at Spa- Francorchamps.

“Raced by our customers, the predecessor scored class victories at the 24 Hours of Daytona and the 12 Hours of Sebring. Furthermore, the car has clinched numerous titles in international GT3 sprint and long-distance championships.”

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