Porsche engineers have been spied testing the new 2015 911 GT3 RS at the Nürburgring. The more hardcore version of the track-focused 911 GT3 was originally scheduled to debut this summer, but its arrival was likely delayed due to engine fires in 2014 model-year 911 GT3s.
There has been a lot of speculation if the new GT3 RS will receive the turbo treatment. Judging from the below video, it’s safe to say that the GT3 RS be naturally aspirated. There is speculation that the current GT3’s 3.8L engine may grown to achieve more than 475 hp, or perhaps tuning the engine for greater responsiveness.
The GT3 RS has a host of visual differences from the standard GT3, such as a widened track for wider wheels and tires, a much larger rear wing, modified rear fender and bumper air extraction routes, and a larger lip around the front spoiler.
While it is uncertain whether the GT3 RS will offer a manual gearbox, the lightning-fast shifting of the one in the video indicates that the PDK will be used.
