Porsche Motorsport has officially unveiled and revealed all technical specifications for its new GT3 car, which will compete globally with client teams in 2019.
The most recent Porsche 911 GT3 R will be based on the 992 version of the road-going Porsche 911. According to the German manufacturer, “greater power, smarter aerodynamics, and enhanced balance” are the primary focuses of the new car.
Last month, Porsche unveiled the first photographs of its Type-922 GT3 race vehicle from an April test at Spa-Francorchamps. This weekend, Porsche unveiled the car for the first time to the public 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 litres surpassing the 4 litres of the Type-991.2 car, which is currently in its final season.
This has resulted in a 5% boost in engine capacity, which Porsche hopes will allow it to meet its goal of “accessing bigger reserves for various BoP categories.”
Porsche claims to have adjusted the torque and power curves throughout the full rpm range to make the power unit “more suitable” for novice drivers.
Similar to the 2019 model, which has won several major endurance events, including 24-hour races at Spa, the Nürburgring, and Daytona, the new car’s engine is a water-cooled, rear-mounted, flat-six boxer with four-valve technology and direct fuel injection.
Nonetheless, the engine has been shifted forward by 5.5 degrees to make room for the diffuser. In addition, the alternator and air conditioning compressor have been relocated to sit in front of the engine and transmission.
The sequential six-speed transmission is derived from the current generation 911 GT3 Cup car, which also belongs to the 992 generation.
Sebastian Golz, project manager for the Porsche 911 GT3 R, stated, “We nailed the bullseye with the wildly popular predecessor.”
“Therefore, the bar is set high for its successor. Our mission was less about making the new 911 GT3 R faster, as the classification inside the BoP’s performance parameters quickly negates this advantage.
“For us, it was most important that our customers could drive the race car quickly for longer.
“This demands durability, therefore we concentrated primarily on enhancing the vehicle’s manoeuvrability.
This is reflected in the new 4.2-liter engine’s broader useful rev band, more stable and consistent aerodynamics, and reduced stresses on the rear tyres, which increases their longevity potential.
Additionally, the 2023 Porsche 911 GT3 R features “modified” suspension components designed to improve steering precision and reduce tyre wear. The 2019 model features a front axle with a double-wishbone arrangement and a rear axle with a multi-link design.
As a result of the rear wheels being relocated further back, the wheelbase has increased from 2,459 to 2,507 millimetres.
The aerodynamic shape of the new car includes a raised underbody and a rear diffuser, and Porsche has devised a’swan-neck’ attachment for the back wing. Similar rear wing configurations have been introduced to the Evo II version of the Audi R8 LMS GT3 and the Ferrari 296 GT3 for this year.
The driver position has been shifted closer to the centre of the cockpit for improved ergonomics within the roll cage and the newly established side impact protection by the FIA.
The steering wheel incorporates components from past Porsche racing vehicles, including the 10.3-inch display from the 911 GT3 Cup and the clustered multi-switch concept from the GTE-specification 911 RSR-19.
Porsche client teams will be able to run the new GT3 in a variety of events that employ the worldwide formula, such as the FIA World Endurance Championship and the 24 Hours of Le Mans, which will accept GT3-based gear beginning in 2024.
Michael Dreiser, sales director at Porsche Motorsport, remarked, “The new 911 GT3 R has large shoes to fill.”

Since 2019, its predecessor has won practically everything there is to win in the GT3 scene across four seasons.
“Among its most notable achievements are victories in the 24-hour races at the Nürburgring and here at Spa-Francorchamps.
“The predecessor was raced by our customers and won class victories at the 24 Hours of Daytona and the 12 Hours of Sebring. Additionally, the vehicle has won multiple international GT3 sprint and long-distance competitions.”
Porsche has listed a price of €511,000 ($521,188 USD) including VAT for its 2023 competitor, which is anticipated to make its non-homologated debut later this year.
