During the 2015 NAIAS in Detroit, Porsche has confirmed the highly anticipated 911 GT3 RS will receive a new engine.
Speaking to AutoExpress during the show, Porsche R&D boss Wolfgang Hatz disclosed the model will be powered by a completely new naturally aspirated six-cylinder unit. This powerplant will eventually make its way into other models of the German brand. According to latest rumors, the engine in question is a 4.0-liter unit, generating 500 bhp (373 kW).
Hatz also confirmed at launch the sports machine will be available only with a PDK automatic transmission, while a manual option hasn’t been ruled out for the coming years. He hinted the GT3 RS version will be a much more extreme compared to the GT3. ”Performance has to be the main objective. Customers love the current GT3. The RS has to be the peak. The 991 GT3 was very much a surprise for everybody because it’s a very useable car for every day. The GT3 RS will be more extreme.”
