The new Porsche 911 GT3 R will be presented to the public at this year's 24 Hours of Spa-Francorchamps. From the 2023 season, Porsche customer teams will be able to campaign with the new racing car at global motorsport events compliant with GT3 regulations. The car is based on the latest 911 of the 992 generation. Compared to its predecessor, the new 911 GT3 R has a larger engine that produces up to 416 kW (565 hp), a more stable aerodynamic performance. and optimized vehicle balance. 

With the latest generation of the 911 GT3 R, Porsche car has introduced a new customer car. The new challenger to the GT3 series worldwide is based on the current 992 generations and will be ready to race at the start of the 2023 season. Development begins in 2019. What most matters is to improve handling for professionals, experts and the so-called gentleman steering wheel, as well as tapping into larger reserves of performance for the various Balance of Performance (BoP) classifications. 

Another goal is to streamline racing management for teams and reduce operating costs. Michael Dreiser, Sales Manager at Porsche Motorsport said: “The new 911 GT3 R has big shoes to fill. Its predecessor has won almost everything in the GT3 arena in four seasons as of 2019. Its remarkable records consist of comprehensive victories at the 24-hour races at the Nürburgring as well as here. at Spa-Francorchamps. Driven by our customers, the predecessor scored class wins at 24 Hours of Daytona and 12 Hours of Sebring. 

The new model faces an enormous amount of work in the hands of  Porsche customer racing teams. After announcing the GT3 class as the professional category in the North American IMSA series, the FIA ​​WEC World Endurance Championship has matched: from 2024 GT3 racing cars such as the new 911 GT3 R will be eligible to participate. 

They had great success with their wildly successful predecessor. Accordingly, the standard for its successor is very high,” emphasized Sebastian Golz, 911 GT3 R project manager at Porsche Motorsport. Its mission is to make the new 911 GT3 R even faster than before or its predecessors. For them, it is of the utmost importance that our customers can drive their racing cars faster and longer. This requires durability and that's why we've mainly focused on improving handling. 

This is reflected in the new 4.2-liter engine's wider usable rev range, more stable and consistent aerodynamics and reduced load on the rear tires, allowing their potential to drag longer.

Suspension modified in many details

The new 911 GT3 R's suspension system - which includes many modifications - promotes handling, allows for more precise steering, ensures less rear tire wear, and reduces time to change settings. 

For this, many components and technical solutions have been taken from the 911 RSR. At the front axle, a modern double wishbone system controls the wheels. The rear axle sports a multi-link design. The KW damper has been further refined and offers five adjustable settings. Configuration changes are made with so-called shims. These panels allow for precise adjustment without the tedious need to re-align the suspension afterward. 

The optimal position of the central pivot points on the front axle frees up space for the aerodynamic concept of “underfloor racing”. As on the 911 RSR, this raised chassis allows clean air to flow to the rear diffuser and reduces racing sensitivity, i.e. high braking roughness. The rear wheel recedes a bit, helping to extend the wheelbase from 2,459 to 2,507 mm. It also reduces the load on the rear tire and improves tire consistency over a longer period.

Lightweight body with an aluminum-steel composite design

In a car like the new 911 GT3 R, function comes first. However, Grant Larson of Style Porsche succeeds in creating exceptionally beautiful and harmonious shapes. They highlight the nine-and-eleven heritage and blend it with sophisticated effects. It is most precious to be mentioned that, this is reflected in aerodynamics. 

Strengths: raised chassis in front of the front axle, combined for the first time with a smooth underbody and rear diffuser. Such a combination improves the downforce without increasingly enormous drag. The rear wing now has gooseneck support. This ensures clean airflow under the wing and thus improves the aerodynamic efficiency of the part. 

In terms of safety, the new 911 GT3 R follows a zero-tolerance approach. The saddle is closer to the center of gravity. This allows Porsche to optimally adapt the position of the more comfortable seats with the improved roll bar and the new FIA side impact protection. 

As with the first model, the steering wheel and pedals can be adjusted vertically to suit the rider. Porsche experts have once again taken a close look at the six-point seat belts: the tabs now slide into the clasps even faster through special ramps, saving about a second in pit stop time. to shift gears to the pilot. 

The steering wheel design also received more improvements than the previous model. It combines elements proven on the latest generation 911GT3 Cup and 911 RSR racing cars. For example, the 10.3-inch screen comes from the successful coupe racer, with the multi-button concept adopted by class winner Le Mans. 

The high-performance LED headlights of the 911 GT3 R are based on the so-called collimation technology that Porsche has developed, among other things, for the LMDh 963 prototype. The device works like a magnifying glass, only backward. again. It illuminates a particularly large area of ​​the racecourse and is a significant improvement over the previous model, which was previously considered class president.

Engine based on the 911 generation 992

At the heart of the new race car is a near-standard engine based on the  911 powerhouse of the 992 generation. Like the previous model, it is a water-cooled flat-six with four-valve technology and direct fuel injection. The main novelty is the engine displacement: like the 911 RSR, the engine displacement of the new 911 GT3 R has increased by 5%, from 3,997 to 4,194 cm3. This increases the maximum motor power to about 416 kW (565 PS). 

But above all, Porsche has optimized the torque and power curves across the entire rev range. Therefore, the new 4.2-liter six-cylinder engine is more suitable for gentlemen who drive. 

The high-revving six-cylinder distributor features a supercharger and sits in the classic rear position, thus improving traction and braking. However, it has been tilted forward at 5.5 degrees, creating more headroom for the diffuser under the hood. Auxiliary components such as the alternator and air conditioning compressor have been conveniently moved forward and down the front of the engine and transmission, which has a positive effect on the mass balance. of the 911 GT3 R. Sequential six-cylinder Speed ​​contest mesh gearbox derived from the current 911 GT3 Cup. The gearshift paddles control an electronic shift drum actuator that allows for exceptionally quick and precise gear changes.

Racing brake calipers by the specialist AP

In addition to the aluminum one-piece brake calipers, the brake discs of the new 911 GT3 R are now also supplied by the car company AP. The ventilated and grooved steel front disc measures 390mm in diameter and is powered by six pistons. 

At the rear, four-piston brake calipers and 370mm discs are fitted. Porsche's traction control system has also been tweaked. The new 911 GT3 R is only Porsche Motorsport's second race car based on the current 992-generation 911 after the 911 GT3 Cup. 

The lightweight body with a smart aluminum-steel design is inspired by the production model, but with major modifications for use in the 911 GT3 R. Almost all body components are lightweight carbon, including front and rear bonnets, doors, side skirts, rear wing and roof.
