Porsche Motorsport has officially launched and released the full technical details of its new GT3 car that will enter global competition with customer teams next year.
The latest Porsche 911 GT3 R will be based on the 992nd generation Porsche 911 roadster. According to the German manufacturer, the main focus areas of the new car are “more power, improved aerodynamics and optimum balance”.
Porsche revealed the first images of the Type-922 GT3 last month from April testing at Spa-Francorchamps, while this weekend it made its public debut at the TotalEnergies 24 Hours of Spa.
The new 911 GT3R has a larger engine than its 2019 predecessor, with a 4.2-liter capacity exceeding the 4-liter 991.2 now entering its final season.
This has increased engine capacity by 5 percent, which Porsche hopes will achieve its goal of “taking advantage of larger reserves for different BOP ratings”.
Porsche says it has improved torque and power curves across the entire rev range to make the power unit “more convenient” for amateur drivers.
Like the 2019 model – which has won several major endurance races including the 24 Hours races at Spa, Nürburgring and Daytona – the new car’s engine is a boxer-back, flat-six water-cooler with four-valve and direct. fuel injection.
However, the motor has been tilted forward 5.5 degrees to provide more room for the diffuser. In addition, the alternator and air conditioning compressor were moved forward and down the car to sit in front of the engine and gearbox.
The six-speed sequential gearbox is derived from the current 911 GT3 Coupe, which is also part of the 992 generation.
“We hit the mark with our massively successful predecessor,” said Sebastian Jules, Porsche 911 GT3R Project Manager.
Accordingly, the standard to which he will succeed is high. Our job wasn’t about making the new 911 GT3R faster – rating within the performance windows set by BoP quickly eliminates that advantage.
“For us, it was primarily about our customers being able to drive a race car faster for longer.
“This requires durability and that is why we focused primarily on improving the ability to drive.
This is reflected in the new 4.2-liter’s wider usable rev range, more consistent and stable aerodynamics, and lower loads on the rear tires, allowing it to last longer. “
The 2023 Porsche 911 GT3 R also includes “modified” suspension components designed for more precise steering and reduced tire wear. The front axle features a double wishbone design while the rear axle features a multi-link design, as on the 2019 product.
There was a slight increase in wheelbase from 2,459 to 2,507 mm thanks to the rear wheels being moved rearward.
The aerodynamic appearance of the new car is distinguished by a raised lower section and rear diffuser, while Porsche has introduced a swan neck mount for the rear spoiler. Similar rear spoiler designs have been added to this year’s Evo II version of the Audi R8 LMS GT3 and Next year Ferrari 296 GT3.
Inside the cockpit, the driver’s position has been moved closer to the center to improve ergonomics inside the rolling cage and the newly developed FIA side-impact protection.
The steering wheel includes elements derived from other Porsche racing cars, such as the 911 GT3’s 10.3-inch head-up display and the multi-cluster switch concept found on the GTE-spec 911 RSR-19.
Teams of Porsche customers will be able to operate the new GT3 in a wide range of series that use the global formula, including the FIA World Endurance Championship and 24 Hours of Le Mans accepting GT3-based machines from 2024.
“The new 911 GT3R has a great shoe to fill,” commented Michael Dreiser, Director of Sales at Porsche Motorsport.
“Its predecessor has won almost everything to win in the GT3 scene in four seasons since 2019.
“Her notable successes include overall victories in the 24 Hours of races at the Nürburgring and also here at Spa-Francorchamps.
“In raced by our customers, our predecessor achieved quarterly victories in the 24 Hours of Daytona and the 12 Hours of Sebring. Moreover, the car claimed several titles in the International GT3 Championships in long-distance racing.”
Porsche has announced a €511,000 price tag (US$521,188) plus VAT for its 2023 rival, which is expected to make its racing debut later this year.
