Porsche has only just released its new 992-generation 911 GT3 to customers globally, but development of the motorsports-bred 911 GT3 RS is still underway. Videos of a GT3 RS prototype testing at the Nurburgring this week have surfaced, and it clues us into the future of the car’s rivalry with the C8 Corvette Z06.
Like the C8 Corvette Z06, the 911 GT3 RS will feature an engine derived from factory-backed race cars. In the case of the Z06, it’s a new 5.5L flat-plane crank V8 that was developed in the back of the IMSA GTLM championship-winning C8.R GTE. And, if you recall, the C8.R beat the 911 RSR in both 2020 and 2021. The GT3 RS will continue to use a version of Porsche’s 4.0L flat-six, currently employed in the back of the company’s 911 Carrera Cup cars. The RSR has moved onto a larger 4.2L flat-six, in case you’re wondering.
Power figures for the 992-gen GT3 RS remain unannounced, but the current 992 GT3 Touring offers 510 hp on tap, while the previous 991-gen GT3 RS touted a peak output of 520 hp and 346 lb-ft of torque from the same engine. Expect a conservative bump in output when the 992 911 GT3 RS debuts later this year. The C8 Z06 will show up with 670 hp out of the box, Chevrolet is promising it will be a 10-second car in factory form. Based on inconvenient circumstances, its official Nürburgring lap time may never happen.
Compared to the GT3, the prototype GT3 RS shows additional vents on the hood and front fenders which likely contain active shutters. The GT3 RS also shows off a more aggressive front splitter, new side skirts, and a massive, swan-neck rear wing stolen right off the Carrera Cup cars. The wing also looks to have an active element.
Development of the GT3 RS takes after the 911 GT3 R race car, a car that will eventually go head to head with the upcoming Z06 GT3.R which will ultimately replace the C8.R when it arrives in 2023. The latest iteration of Corvette vs 911 rivaly is shaping up to be one of the best fights yet.
