550Hp Porsche Cayenne Turbo S Unveiled in Beijing

Porsche selected the Beijing Show to unwrap the most powerful edition of its Cayenne SUV model up to date. The top-of-the-range Cayenne Turbo S benefits from a modified exhaust system and improvements in engine control that help boost the standard Cayenne Turbo’s 4.8-liter V8’s output from 500 Hp to 550 Hp while there has also been an increase in maximum torque by 50 Nm to 750 Nm. -Continued

The Cayenne Turbo S accelerates from 0 to 100 km/h (62 mph) in 4.8 seconds (standard Turbo: 5.1 sec) and its top speed is 280 km/h or 174 mph. According to Porsche, despite the fact that the new Turbo S is faster and more powerful than the regular Turbo model, the fuel efficiency figures for the Turbo S are exactly the same as those for the Cayenne Turbo.

In addition to the performance improvements, from the outside, the Turbo S is distinguished by its 21 inch SportPlus alloy wheels housed within its painted wheel arches and by a sports exhaust system with four tail pipes made from aluminum investment casting. The air intake grills and wheel arches are painted the same color as the car body.

Inside, the new Cayenne top-of-the range Turbo S gets front sports seat with Comfort Memory Package, rear seating with individual seat contours, aluminum door panels showing the name plate together with leather upholstery in two exclusive dual-color combinations (black / Havana and black / steel gray) plus a leather steering wheel with padded center.

The Turbo S will be introduced into the market as from August 2008. The international basis price is EUR 111,400 or $175,000. On a side-note, the Turbo S, as with the rest of the revised Cayenne range will be offered with Porsche’s optional Ceramic Composite Brake. The front axle ceramic disks are 410 mm in diameter, whereas the rear axle disks are 370 mm in diameter. Deceleration takes place via six-piston calipers at the front and four-piston calipers at the rear
