The standard Cayenne Turbo reaches its peak torque of 457 lb.-ft. at 2,250 rpm, but the 2006 Porsche Cayenne Turbo S produces 479 lb.-ft. at just 2,000 rpm. The Turbo S hits its peak 531 lb.-ft. at 2,750 rpm and maintains that thrust until 3,750 rpm. Not only does it produce more total power, but it produces more power longer too. In street vernacular, that results in hauling ass more than any other SUV-driving mofo on the road. “It surprised even us,” said Porsche engineer Jürgen Kern about the jump in power. “The turbo is already powerful enough, but this…” His voice trailed off as he pushed the accelerator and thrust my back flat against the seat.
