Only available as a 2006 model, the previous Turbo S made 520 hp, a massive 16% increase over the regular Cayenne Turbo's 450 hp. But that is ancient history and this new 2009 Cayenne Turbo S with a 4.8-liter V8 twin turbo engine pushes its way up to 550 hp (404 kW) and 750 Nm simply with a modified exhaust system and improved engine control unit. Despite the increase in power, the Turbo S manages to maintain the same fuel efficiency figures as the Cayenne Turbo (500 hp / 368 kW).
The Turbo S receives special 21-inch SportPlus alloy wheels, exclusive “lava gray metallic” paint option and air intake grills and wheel arches painted body color. Also, for the 2009 model year, Porsche will offer ceramic composite brakes for the first time in a sector other than the sports car sector, including the Cayenne S, GTS and Turbo.
"The Porsche Cayenne Turbo S accelerates from zero to 100 km/h in 4.8 seconds and its top speed is 280 km/h. The Turbo S will be introduced into the market as from August 2008. The international basis price is EUR 111,400."
