Rumor Mill: Porsche 911 May Gain Three Turbochargers

With each new 911, we expect Porsche to push its limits with new and sometimes outrageous displays of engineering. The new 2012 Porsche 911 991, for example, sports the world’s first seven-speed gearbox in a passenger car. Surprising indeed, but now Porsche is rumored to one up that with a tri-turboed 911. According to the British publication Autocar , Porsche engineers are already in the late stages of research and development of a triple-turbo 911. Prototypes have already been commissioned to test the new powerplant and Autocar claims to have found German patent applications filed for the system. We’ve already heard about BMW’s newest quartet of M-powered cars -- the X6 M50d, M550d xDrive, M550d xDrive Touring, and X5 M50d -- which all feature a 3.0-liter, triple-turbo, inline-six diesel engine rated at 381 hp and 546 lb-ft of torque. Autocar says the Porsche’s boxer six will employ a similar turbo setup, with two traditional turbines supplemented by a smaller unit to help with low-end response. No official word yet on power outputs, but expect numbers to be north of the 500 hp and 480 lb-ft of torque provided by the 3.8-liter, twin-turbo flat-six in the 997. Most importantly, the added boost should best the insanely fast 0-60 time achieved by the 997 turbo. When we last drove a 2010 Porsche 911 Turbo, 0-60 mph came in less than four seconds.
