Photos released today are of the Cayenne Turbo, which will be powered by a Porsche?designed 4.5-liter, twin turbocharged V-8 engine rated at 450 horsepower and producing 457 lb-ft of torque. Porsche also announced a second model, the normally aspirated, 4.5-liter, V-8-powered Cayenne S, which is rated at 340 horsepower and 310 lb-ft of torque. The Cayenne Turbo accelerates from 0 to 100 km/h (62 mph) in 5.6 seconds, vs. 7.2 seconds for the Cayenne S. The Cayenne?s towing capacity is 3,500 kilograms, or 7,716 lbs.
A six-speed Tiptronic S transmission is standard equipment on the Cayenne Turbo, and both Cayenne versions have permanent all-wheel drive, an inter-axle differential lock and additional low-range gears, and the Porsche Stability Management (PSM) system.
Additional front air inlets, power domes on the hood, and four exhaust tailpipes help distinguish the Cayenne Turbo from the Cayenne S. The Cayenne Turbo and Cayenne S are 75.9 inches wide and 66.9 inches tall, with a wheelbase of 112.4 inches. The overall length of the Turbo version is 188.43 inches, vs. 188.27 inches for the Cayenne S.
?Porsche has been at the forefront of all-wheel-drive design,? said Frederick J. Schwab, PCNA president and CEO. ?From the Lohner-Porsche in 1900 to the Porsche 959 in 1985, Porsche has been engineering four-wheel drive and all-wheel drive vehicles. The Cayenne is a natural for us, and it will put the sport in sport utility vehicles.?
