Porsche Motorsport has officially launched and released the full technical details of its new GT3 car, which will compete globally with customer teams next year.

The latest Porsche 911 GT3 R will be based on the 992 generation of the Porsche 911 street model. According to the German manufacturer, the main focus areas of the new vehicle are “more power, advanced aerodynamics and optimized balance.”

Porsche last month unveiled the first images of its Type-922 GT3 car from an April test at Spa-Francorchamps, while this weekend it presented the car to the public for the first time at the TotalEnergies 24 Hours of Spa.

The new 911 GT3 R has a larger engine than its 2019 predecessor, with a displacement of 4.2 liters exceeding the 4 liters of the Type-991.2 car, which is now in its final season.

This has resulted in a 5 percent increase in engine power, which Porsche hopes will achieve its goal of “tapping larger reserves for different BoP classifications”.

Porsche says it has optimized torque and power curves across the rev range to make the powerplant “better suited” to amateur drivers.

Like the 2019 model – which has won several major endurance events, including the 24-hour races at Spa, the Nürburgring and Daytona – the new car’s engine is a rear-mounted, water-cooled, six-cylinder boxer with four-valve technology and direct fuel injection.

However, the engine is tilted 5.5 degrees forward to create more space for the diffuser. In addition, the alternator and air conditioning compressor have been moved forward and downward in the car to sit in front of the engine and gearbox.

The six-speed sequential transmission is derived from the current 911 GT3 Cup car, which is also part of the 992 generation.

“We hit the mark with its hugely successful predecessor,” said Porsche 911 GT3 R project manager Sebastian Golz.

“The bar for his successor is therefore high. Our task was less to make the new 911 GT3 R even faster – the ranking within performance windows set by the BoP quickly negates this advantage.

“For us, the main thing was that our customers could drive faster with the racing car.

“This requires durability, which is why we focused mainly on better driving characteristics.

“This is reflected in the wider usable rev band of the new 4.2-litre engine, the more stable and consistent aerodynamics and the lower load on the rear tires, extending their potential.”

The 2023 Porsche 911 GT3 R also includes “custom” suspension components designed for more precise steering and less tire wear. The front axle has a double wishbone layout, while the rear axle has a multi-link design, as is the case with the 2019 product.

The wheelbase has increased slightly from 2,459 to 2,507 mm due to the rear wheels being placed further back.

The new car’s aerodynamic profile features a raised underside and rear diffuser, while Porsche has introduced a ‘gooseneck’ mount for the rear wing. Similar rear wing layouts have been added to the Evo II version of this year’s Audi R8 LMS GT3 and next year’s Ferrari 296 GT3.

In the cockpit, the driver’s position has been moved closer to the center for better ergonomics in the roll cage and the newly developed FIA side-impact protection.

The steering wheel incorporates elements derived from other Porsche race cars, such as the 10.3-inch display from the 911 GT3 Cup and the clustered multi-switch concept found in the GTE-spec 911 RSR-19.

Porsche customer teams will be able to drive the new GT3 car in a wide range of series using the global formula, including the FIA ​​World Endurance Championship and the 24 Hours of Le Mans, which will accept GT3-based machines from 2024.

“The new 911 GT3 R has big shoes to fill,” said Michael Dreiser, sales director at Porsche Motorsport.

“Its predecessor has won almost everything there is to win in the GT3 scene in four seasons since 2019.

“His notable successes include overall victories at the 24-hour races at the Nürburgring and here at Spa-Francorchamps.

“The predecessor, driven by our customers, achieved class wins at the Daytona 24 Hours and Sebring 12 Hours. In addition, the car has won numerous titles in international GT3 sprint and endurance championships.”

Porsche has declared a price of €511,000 ($521,188 USD) plus VAT for its contender in 2023, who is expected to make its racing debut in non-homologated version later this year.
