In addition to the 911 Turbo, Dr. Ing. h.c. F. Porsche AG of Stuttgart, Germany, is presenting another new automobile at the Geneva Motor Show. The new 911 GT3 will be unveiled to the world public for the very first time on February 28, 2006. This two-seater sports coupe will go on sale across Europe in May 2006.
In the 911 model range, the abbreviation GT3 stands for pure, unadulterated driving pleasure. With its uncompromising dynamics, this model impresses not only in normal day-to-day driving but also on the racetrack. The 305-kW (415-bhp) 3.6-liter flat-twin engine produces a specific output of 84.7 Kilowatts (115.3 bhp) per liter of displacement. This performance places the new-generation GT3 in its displacement class at the pinnacle of road-legal production sports cars with naturally aspirated engines.
