With the latest generation of the 911 GT3 R, Porsche unveils a new customer racing car. The new challenger for GT3 series around the world is based on the current 992 generation and will be ready to race at the beginning of the 2023 season. Development began in 2019. Priority was given to further improving the driveability for professionals and so-called gentleman drivers, as well as tapping larger performance reserves for different Balance of Performance (BoP) classifications. Another focus was on streamlining the handling of the race car for the teams and reducing the running costs.
“The new 911 GT3 R has big shoes to fill,” says 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. The new model faces a massive workload in the hands of the Porsche customer racing teams.”
After the GT3 class was announced as a professional category in the North American IMSA series, the FIA WEC World Endurance Championship follows suit: From 2024, GT3 racing cars such as the new 911 GT3 R will be eligible to take part in the 24 Hours of Le Mans for the first time.
“We hit the bull’s eye with the enormously successful predecessor. Accordingly, the bar for its successor is high,” emphasises Sebastian Golz, 911 GT3 R Project Manager at Porsche Motorsport. “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-litre engine’s broader usable rev band, more stable and constant aerodynamics and lower loads on the rear tyres, which allow their potential to last longer.”
At the core of the new racing car is the near-standard engine based on the 992-generation 911 power plant. Like in the previous model, it is a water-cooled flat-six engine with four-valve technology and direct fuel injection. The main new development is the displacement: like the 911 RSR, the capacity of the new 911 GT3 R has increased by a good five per cent from 3,997 to 4,194 cc. This has boosted the engine’s peak output to around 416 kW (565 PS). First and foremost, however, Porsche has optimised the torque and power curve across the entire rev range. Consequently, the new 4.2-litre six-cylinder is better suited to gentleman drivers.
The new 911 GT3 R is just the second racing car from Porsche Motorsport to be based on the current 992-generation 911 after the 911 GT3 Cup. Its lightweight body with an intelligent aluminium-steel composite design draws on the production model, albeit with major modifications for use in the 911 GT3 R. Almost all body components are made of lightweight carbon, including the front and rear lids, doors, side panels, rear wing and roof. The wheel arches are made of aramid fibres.
In a vehicle like the new 911 GT3 R, functionality stands at the forefront. Nevertheless, Grant Larson from Style Porsche again succeeded in creating particularly stunning and harmonious shapes. They accentuate the heritage of the nine-eleven and blend it with sophisticated efficiency. Most notably, this is reflected in the aerodynamics. The key points: an elevated underbody at the fore of the front axle, for the first time in conjunction with a smooth undertray, and a rear diffuser. This combination improves downforce without a significant increase in drag. The rear wing now features a swan-neck mount. This ensures a clean airflow under the wing and thus improves the aerodynamic efficiency of the component.
