Beginning in December 2004, Porsche will offer increased horsepower for the Cayenne Turbo through its Tequipment program. The upgrade includes increasing the engine performance from 450 to 500 horsepower, a reinforced brake system and an adapted suspension system requiring 19-inch or larger wheels. Thus equipped, the Cayenne Turbo can reach a top test-track speed of 167 mph (series production: 165 mph), and a 0 to 60 mph time of 4.9 seconds (Cayenne Turbo with 450 horsepower: 5.2 seconds). Fuel consumption, as with the 450 horsepower Cayenne Turbo, remains unchanged at 13 mpg city/18 mpg highway.



Porsche achieved the 50 extra horsepower by optimizing the flow design of the intercooler and other engine management developments. In conjunction with changed accelerator pedal characteristics, this results in an optimized torque build-up and even sportier engine characteristics. The maximum torque has increased from 460 to 515 pounds-feet, and maximum torque is available between 2,250 and 4,750 rpm.



The front brake system has a new aluminum six-piston monobloc disc-brake caliper with a brake pad area that is more than 12 percent larger than the standard Cayenne Turbo front brake system. The brake disc is 14.96 inches/380 mm in diameter and 1.5 inches/38 mm thick (series production: 13.78 inches/350 mm in diameter and 1.34 inches/34 mm thick). Porsche engineers also optimized the brake ventilation. The rear brakes discs have also been enlarged to 14.1-inches/358 mm (series production: 13 inches/330 mm).



The Cayenne Turbo with the Tequipment upgrade is available for a U.S. MSRP of $109,200. A retrofit package is available through Tequipment for $18,500 plus installation at an authorized Porsche dealer.
