Porsche Cayenne Turbo

Neil Campbell hit 149.16 mph and will now target the world record.

0-60 mph comes in under four seconds.

Top Gear stages a three-way, quarter-mile drag race against the Porsche Cayenne Turbo S, Land Rover Range Rover Sport SVR, and Jeep Grand Cherokee SRT.

Porsche knows that to keep up, a model has to keep evolving. For the latest 2015 evolution of the Cayenne Turbo S on display at the Detroit Auto Show, it now packs integral turbos housed directly in the exhaust manifolds. The move allows power to grow to 562 horsepower and 590 pound-feet of torque, while shedding a half-second off the sprint to 60. The German brand also claims that the improved version can lap the Nurburgring Nordschleife in a blink less than eight minutes.
