The Porsche Cayenne Turbo S was only around for one year before the SUV was (slightly) redesigned. The Turbo S model disappeared for a while, but returned to the Cayenne lineup at this year's Beijing Auto Show. Now the Cayenne Turbo S packs 550 hp and 553 lb-ft of torque.
Changes between the Turbo and Turbo S are minimal, so don't expect to see a totally different vehicle when one cruises past you on the road. Fender flares are a little wider and the rims are 21-inches on the Cayenne Turbo S. Functional changes include a remapped engine computer, different air intakes, and the exhaust system. That's enough to thrust the Cayenne Turbo S from 0 to 60 mph in less than 4.8 seconds.
With all that power, it's only fitting that Porsche is offering ceramic composite brakes on this monster of an SUV. We probably don't need people rocketing around in 5200-pound vehicles that can blast past 60 mph so quickly without such incredible brakes. Top speed is an equally insane 174 mph.
