The performance chops of the new Porsche 911 are undeniable, but the German sports car maker is preparing its even more potent GT3 variant for the 2013 Geneva Motor Show, reports Autocar. New info on that race-derived model has come to light, hinting at a more powerful and lighter 991-generation GT3.
Instead of adopting the 493-hp, 339-lb-ft 4.0-liter flat-six of the previous-generation GT3 RS 4.0, the 991 GT3 is set to receive a tuned version of the naturally aspirated 3.8-liter unit, which Porsche insiders have hinted will produce around 450 hp. That figure would represent an increase of 15 hp over the outgoing GT3, and could grant the model a 0-60 mph time in the sub-4-second range. Also helping with acceleration is the increased use of lightweight materials in the body. Just as in past years, the GT3 will see less interior trim and equipment compared to standard 911 models, and will also have its rear seats removed. In total, the GT3 shaves off around 88 pounds from its predecessor’s curb weight of roughly 3075 pounds, according to insiders.
But one aspect of the next-gen car not helping in the GT3’s lightweight mission is its choice of transmission, which insiders suggest will be exclusively a seven-speed PDK dual-clutch unit. The PDK is heavier than the automaker’s manual gearbox, and the lack of a row-your-own option will likely be a point of controversy for purists.
Recent spy shots of the 991-generation GT3 show the car will feature many of its traditional hallmarks, including wider air ducts, flared fenders, and the requisite large fixed rear wing. Once the car is unveiled in Geneva, GT3 order books are expected to open not long after.
