Porsche's big announcement in Detroit isn't a sports car. No, no. The Motor City is best suited for bigger vehicles (and, hell, who would want to try and upstage the new Corvette anyway), and Porsche doesn't shy away from the competition. At the very moment Jeep was unveiling the 2014 Grand Cherokee SRT8, we learn that he 2014 Cayenne Turbo S is going to be faster—thanks to a 560hp engine.

How fast? Max speed 175 mph and a 0-60 of 4.3 seconds.
