Introducing the new Porsche 911 GT3 R.

Porsche is unveiling the latest generation 911 GT3 R, a new racing model for customer competition. Based on the latest generation of the 911 (992), the new model, ready to mark the start of the global GT3 competition from the start of the 2023 season, began development in 2019. For professionals and “gentleman drivers”, it optimizes the car’s durability quality and increases its power reserve according to the Balance of Performance (BoP) criteria set by racing regulations. The brand’s engineers worked to better control entry costs as well as optimized fleet management for the team. Porsche Motorsport currently offers the new 911 GT3 R at a price of EUR 511,000 (VAT-exclusive price, excluding optional equipment). “From 2019 onwards the previous model won almost everything in four seasons of the GT3 competition. It stood out remarkably by winning the general category at the 24-hour race at the Nurburgring and also at the Spa-Francorchamps here. The previous generation, led by this one, won its class at Daytona 24 Hours and Sebring 12 Hours Now the Porsche customer team is ready for next season Just like the IMSA in North America, the GT3 category will also be a FIA WEC (World Endurance Championship) event. From 2024, GT3 racing models such as the new 911 GT3 R will be able to compete in the 24 Hours of Le Mans for the first time. It is only natural that the expectations are high for the new model,” said Sebastian of the 911 GT3 R. Golz emphasizes, project manager at Porsche Motorsport: “It was not important for us to increase the top speed of the 911 GT3. This is because classifying a model in terms of performance according to the criteria of a performance balance defined by the Racing Regulations (BoP) is more important than anything else possible. speed advantage. So our main focus was to enable our customers to drive their race cars at high speed for longer periods of time. Therefore, we strive for consistency in performance. We focused on improving the durability qualities of the new model, as evidenced by the new 4.2-liter engine’s extended effective rev range, aerodynamic stability and efficiency, and reduced load on the rear axle to save tires. » The heart of the new racing car is a near-series engine based on the 911’s 992 generation block. Like its predecessor, the new 911 GT3 R is equipped with a flat water-cooled six-cylinder block. , equipped with 4-valve technology and gasoline direct injection system. The main novelty lies in the displacement. Like the 911 RSR, the displacement of the new 911 GT3 R increases from 3,997 cm3 to 4,194 cm3 (+5%). This increases the maximum engine power to almost 565 hp (416 kW). Porsche engineers also focused on optimizing the torque and power curves over the entire rev range, making the new 4.2-liter six-cylinder unit better able to meet the needs of “gentleman drivers”. Cylinder engines are mounted at the rear, a common position to optimize traction and braking. It also tilts forward 5.5° to free up more space for the underbody diffuser. Auxiliary components such as alternators and air conditioning compressors can be moved forward by a good meter and mounted lower upstream of the engine and gearbox to optimize weight distribution. The six-speed sequential gearbox is based on the transmission of the latest generation 911 GT3 Cup. The driver uses the paddles on the steering wheel to control the electronic drum actuator system, which enables particularly fast and precise gear shifts. The chassis of the new 911 GT3 R optimizes durability, increases steering precision and reduces rear tire wear and installation time. For this purpose, many components and technical solutions are borrowed from the 911 RSR. The double wishbone front axle benefits from the latest technology and the multi-link suspension runs on the rear axle. The KW Competition shock absorber has benefited from further improvements and now offers five adjustment configurations. Adjustments are made through parts called “shims”. A washer that allows precise setting changes without having to realign the chassis, a particularly time-consuming operation. The position of the central pivot point of the front axle has been optimized to realize the aerodynamic “race” concept. floor”. As in the 911 RSR, this overhanging underbody softens the airflow to the rear diffuser and reduces pitching, which reduces the vehicle from leaning forward, especially when the springs are compressed during braking. The position of the rear wheels has shifted slightly back, increasing the wheelbase from 2,459 mm to 2,507 mm. This reduces the load on the rear tire, which can improve performance over the long term. In addition to the aluminum competition monobloc brake calipers, the discs for the new 911 GT3 R are now sourced from specialist AP Racing. The front axle has grooves in the internally ventilated steel discs. It has a diameter of 390 mm and is operated by six pistons. At the rear, four-piston calipers are paired with 370mm discs. Sophisticated software designed for the fifth-generation racing ABS system helps reduce tire and brake lining wear. Porsche’s traction control system has also been optimized, so the new 911 GT3 R is the second Porsche motorsport racing model based on the 992 generation, following the 911 GT3 Cup. The light alloy aluminum and steel body (intelligent composite material) derived from the production model has undergone major modifications. Almost all body components, including the front and rear bonnets, doors, side panels, rear spoiler and roof, are made from lightweight carbon. The wheel arch is made of aramid fiber. Racing models like the 911 GT3 R must meet functional requirements above all else, but Grant Larson, the designer of the Porsche Style department, has once again succeeded in designing an elegant and harmonious form. Thus, the model’s line combines aesthetics and efficiency, emphasizing its stylistic connection to the 911. The car’s aerodynamic elements, especially the underbody (for the first time fully paired and raised from front axle height) and the rear diffuser, prove this. This design feature increases downforce without appreciably increasing drag. In addition, the rear wing now benefits from a gooseneck attachment to ensure fluidity of airflow under the wing, increasing aerodynamic efficiency. When it comes to safety, the new 911 GT3 R does not compromise. The seat is moved closer to the center of the vehicle, providing a more ergonomic seat and optimal positioning compared to the improved roll cage and recently developed FIA side protection. The steering wheel and pedals, like the previous model, are adjustable in length according to the pilot. Porsche experts also modified the six-point safety system. Thanks to the special ramp, the tab retracts into the buckle faster, saving almost a second during pit stops by changing drivers. The design of the steering wheel has also been optimized compared to the previous model. It features elements proven in the current 911 GT3 Cup and 911 RSR models. Therefore, the 10.3-inch screen is taken from the famous single-brand competition model, and the concept of the multi-function button (multi-switch system) is borrowed from the racing model that won many classes at Le Mans. The high-performance LED headlights of the 911 GT3 R are based on the so-called collimator system developed by Porsche for various models, including the new LMDh 963 prototype, which works on the principle of a magnifying glass, but in reverse. It illuminates a large area of ​​the circuit, which is a significant improvement over the headlights of previous models, which were already considered best-in-class.
