2023 Porsche 911 GT3 R race car unveiled

Porsche has released photos and a brief video clip of its redesigned 911 GT3 R racing car, based on the latest 992-generation 911.

The prototype was developed primarily by engineers at Porsche's motorsports partner Manthey Racing and has been running on race tracks across Europe for the past few years.

The new GT3 R's flared wheel arches, vented hood, chunky side skirts, massive rear wing, and equally massive rear diffuser are immediately recognizable. The car also sports center-lock wheels with Michelin racing slicks.

The 911 GT3 R represents the middle tier of 911 racing cars, sandwiched between the 911 GT3 Cup and 911 RSR. Importantly, the GT3 R is the 911 racer closest to the 911 GT3 RS road car.

The GT3 R was last updated for the 2019 motorsports season and still uses the old 991-generation 911 platform; the 992-generation GT3 R should be introduced for the 2023 motorsports season and will likely be revealed later this year Highly likely.

The previous GT3 R produced 550 hp from a naturally aspirated 4.0-liter flat-6. The latest version should have a similar setup and efficiency could be improved. Also expected are a six-speed sequential gearbox, a mechanical limited-slip differential, and a mixed aluminum, steel, and composite construction.

In an interview with Sportscar365 published in June, GT3 R program manager Sebastian Goltz said that the new software tools will make setup changes easier compared to current racers.

"Before, there were three or four different software tools in the notebook, requiring different cables. Now you just plug in one cable and use more features with one piece of software."

The GT3 R tends to cost a little over $500,000 and is commonly seen at events such as the North American IMSA series, the worldwide Intercontinental GT Challenge, and endurance races like those held at the Nürburgring.
