December 5, 2006 Four years after its debut, Porsche has unveiled the second generation Cayenne. When they go on sale in February 2007, the new Cayenne, Cayenne S and Cayenne Turbo will have more powerful, direct petrol injection engines. These Direct Fuel Injection (DFI) power units lower the fuel consumption of individual models by over 8 percent (NEDC). In real driving conditions, Porsche claims savings of up to 15 per cent are possible. The new Cayenne models can be further enhanced by the new Porsche Dynamic Chassis Control (PDCC) roll stabiliser system - an optional active anti-roll system that significantly reduces body roll during cornering, resulting in improved handling and agility, greater directional stability and ride comfort. When off-road, the system increases axle articulation for improved traction.
