Porsche showed its new 911 GT3 R during the Spa 24 Hours. From the 2023 season, customer teams can use the racing car at motorsport events based on GT3 regulations worldwide. This includes, for example, the DTM. The racing car is based on the current 992 generation.
Compared to the previous model, the new 911 GT3 R has a larger engine with up to 416 kW (565 hp), more constant aerodynamic performance and an optimized vehicle balance. Cost: 511,000 euros net.
The new Porsche 911 GT3 R will be used in the DTM from 2023, among other places.
After the GT3 class was announced in the North American IMSA series as a professional category, the FIA World Endurance Championship WEC is following suit: From 2024, GT3 racing cars such as the new 911 GT3 R will be allowed to start at the 24 Hours of Le Mans for the first time walk.
“We hit the bull’s eye with the extremely successful previous model. The bar for the successor is correspondingly high,” emphasizes Sebastian Golz, Project Manager 911 GT3 R at Porsche Motorsport. “Our task was not so much to make the new 911 GT3 R even faster – the classification in performance windows by the BoP quickly compensates for this advantage. For us, it was primarily about our customers being able to drive the racing car faster for longer. Consistency is required. That’s why we focused primarily on improved drivability. This can now be seen in the new 4.2-liter engine’s rev range that can be used more widely, more stable and constant aerodynamics and less strain on the rear tires, which in this way can tap their potential more evenly.”
One of the key elements of the new racing car is the near-series engine based on the 911 generation 992. Like the previous model, it is a water-cooled six-cylinder boxer with four-valve technology and direct fuel injection. Above all, the displacement is new: like the 911 RSR, the new 911 GT3 R increased by a good five percent from 3,997 to 4,194 cm33 to. This has increased the engine’s peak output to around 416 kW (565 hp). First and foremost, however, Porsche has optimized the torque and power curve over the entire speed range. The new 4.2-litre six-cylinder engine is therefore particularly suitable for gentleman drivers.
After the 911 GT3 Cup, the new 911 GT3 R is the second racing car developed by Porsche Motorsport to be based on the current 992 generation.
The high-revving six-cylinder still manages without turbocharging and is traditionally located in the rear, where it has a positive effect on traction and braking behavior. The sequential six-speed constant-mesh gearbox is derived from the current 911 GT3 Cup. The steering wheel paddles control an electronic shift drum actuator that enables particularly fast and precise gear changes.
After the 911 GT3 Cup, the new 911 GT3 R is the second racing car developed by Porsche Motorsport to be based on the current 992 generation. Its lightweight body in intelligent aluminium-steel composite construction is based on the series, but has been heavily modified for use in the 911 GT3 R. Including the front and bonnet, doors, side panels, rear wing and roof, almost all body components are made of lightweight carbon. Aramid is used for the wheel arches.
