Porsche dropped a twin-turbo, 4.5-liter V8 engine good for 520 horsepower and 530 lb.-ft. of torque under the hood of the 2006 Cayenne Turbo S. For perspective, consider that only the Porsche Carrera GT supercar makes more giddy-up out of anything in the Porsche lineup. Acceleration to 60 mph takes just 4.8 seconds of your life, and you can run this puppy up to a top speed of 167 mph. But dipping into the throttle is gonna cost you in more ways than just sticker price. The Cayenne Turbo S is rated by the EPA’s light foot at 13 mpg in the city and 18 mpg on the highway. You’re buying this thing to go fast, so expect a real-world number possibly as low as the single digits.

Suspension components get an upgrade to handle all that additional power – 16-percent more than the already stunningly quick Cayenne Turbo – and the beefed-up brakes feature special cooling ducts for the ventilated front rotors. The rear discs are internally ventilated, and the Porsche Active Suspension Management system gets recalibrated software for the Cayenne Turbo S’s increased performance potential. The 2006 Porsche Cayenne Turbo S gets unique 20-inch SportTechno wheels, too.
