Porsche Motorsport has officially launched and released full 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 Porsche 911 road model. According to the German manufacturer, the main areas of focus for the new vehicle are “more power, sophisticated aerodynamics and optimized balance”.

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

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

This has resulted in a 5% increase in engine capacity, which Porsche hopes will fulfill its goal of “dipping into larger reserves for different BoP classifications”.

Porsche claims to have optimized the torque and power curves across the rev range to make the engine block “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 boxer flat-six. with four-valve technology and direct fuel injection.

However, the engine was angled forward 5.5 degrees to create more space for the diffuser. Additionally, the alternator and air conditioning compressor were moved forward and down in the car to sit in front of the engine and gearbox.

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

“We hit the nail on the head with the hugely successful predecessor,” said Porsche 911 GT3 R project manager Sebastian Golz.

“As a result, the bar for his successor is high. Our task was less to make the new 911 GT3 R even faster – ranking within the performance windows set by the BoP quickly negates that advantage.

“For us, it was mainly about our customers being able to drive the race car faster and for longer.

“It requires durability and that’s why we mainly focused on improving the handling.

“This is reflected in the new 4.2-litre engine’s wider usable rev range, more stable and consistent aerodynamics and lower rear tire loads, allowing their potential to last longer.”

The 2023 Porsche 911 GT3 R also features “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 seen on the 2019 product.

There was a slight increase in the wheelbase from 2,459 to 2,507 mm thanks to the setback of the rear wheels.

The new vehicle’s aerodynamic profile includes a raised underbody and rear diffuser, while Porsche has introduced a “gooseneck” mount for the rear spoiler. 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’s position has been moved closer to the center for better ergonomics in the roll bar and the new side impact protection developed by the FIA.

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 911 RSR-19 in the GTE specifications.

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 24 Hours of Le Mans which accept GT3-based machines from 2024.

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

“His forerunner has won almost everything on the GT3 scene in four seasons since 2019.

“His most notable successes include overall wins in the 24-hour races at the Nürburgring and also here at Spa-Francorchamps.

“Raised by our customers, the predecessor took class wins at the 24 Hours of Daytona and the 12 Hours of Sebring. Additionally, the car has won numerous titles in the GT3 international sprint and long-distance championships.

Porsche has announced a price of €511,000 (521,188 USD) plus VAT for its 2023 competitor, which is expected to make its racing debut in an unlicensed version later this year.
