The new 2013 Cayenne Turbo S is quite simple, really. It’s the most powerful SUV Porsche has ever produced, with 550 horsepower and 553 pound-feet of torque on tap. That colossal grunt can propel the Cayenne Turbo S to 60 miles per hour in a scant 4.3 seconds and onto a top speed of 175 miles per hour. Keep in mind that those numbers aren’t from a featherweight 911, but a big, all-wheel-drive SUV that can haul more than just golf bags.
