Porsche Motorsport has officially launched 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 Porsche 911 road model. According to the German manufacturer, the 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 in Spa-Francorchamps, while this weekend it unveiled the car publicly for the first time at the TotalEnergies 24 Hours in Spa.

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

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

Porsche says it has optimized torque and power curves across the entire rev range to make the powertrain “more 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 engine of the new car is a rear-mounted water-cooled six-cylinder flat boxer with four-valve technology. and fuel injection.

However, the engine was 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 downward 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, also part of the 992 generation.

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

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

“For us, it was mainly about enabling our customers to drive the fastest race car for longer.

“This takes durability and that’s why we focused primarily on improving driveability.

“This is reflected in the wider usable rev range of the new 4.2-liter engine, more stable and consistent aerodynamics and lower rear tire loads, 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 arrangement while the rear axle has a multi-link design, as is the case with the 2019 product.

There was a slight increase in wheelbase from 2,459 to 2,507mm thanks to moving the rear wheels further back.

The aerodynamic profile of the new vehicle features a raised underbody and a rear diffuser, while Porsche has introduced a “gooseneck” attachment for the rear wing. Similar rear wing arrangements 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 cabin, the driver’s position has been moved closer to the center for improved ergonomics within the roll cage and 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 of the 911 GT3 Cup and the cluster multi-switch concept found in the GTE-spec 911 RSR-19.

Porsche customer teams will be able to drive the new GT3 car in a wide range of series using the global formula, including the FIA ​​World Endurance Championship and the 24 Hours of Le Mans which accept GT3-based cars from 2024.

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

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

“His extraordinary successes include overall victories in the 24 Hours races at the Nürburgring and also here at Spa-Francorchamps.

“Corrected by our customers, the predecessor achieved class victories at the 24 Hours of Daytona and the 12 Hours of Sebring. In addition, the car has won numerous titles in the GT3 sprint and long distance international championships ”.

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