Porsche Cayenne â€“ itâ€™s the perfect complement to a 911 for those days you need to carry passengers or lug loads. So weâ€™re impressed by the first pictures of the all-new Cayenne for 2010. Up until now, Cayennes have been thirsty beasts, so the introduction of the S Hybrid is no surprise. The combination of the sophisticated drive and a massive 180kg weight saving means the car is capable of 34.4mpg (New European Driving Cycle) which in anyoneâ€™s books is good. Here is Porscheâ€™s description of the Hybrid: â€œIn the intelligent interaction of the three-litre supercharged V6 and the electric motor, the Cayenne S Hybrid focuses on maximum efficiency from the overall system. Depending on driving conditions, the vehicle reaches this target with either only one drive unit operating by itself or with both drive units working together. In this context the 34 kW (47 hp) electric motor is of course the ideal partner for the 333 hp compressor engine with its high torque at low speeds. Together, the two drive units deliver maximum system output of 380 bhp and peak torque of 580 Nm/427 lb-ft at just 1,000 rpm, with the same kind of performance as the Cayenne S with its V8 power unit. â€œThe two drive units are connected to one another by a separator clutch masterminded by the Hybrid Manager. Indeed, this separator clutch is essential to run the Cayenne S Hybrid either on its electric motor or combustion engine alone, or with both drive units operating together. Given a reserved, moderate style of motoring, for example in a residential area, this allows the driver to cover short distances on electric power alone and therefore absolutely free of emissions and with hardly any noise, driving at a speed of up to 60 km/h or almost 40 mph. â€œTo ensure fast acceleration when setting off, the electric motor may however serve to provide additional thrust through its boosting effect. Intelligent management of the separator clutch makes the transition among the hybrid-specific driving modes most inconspicuous, comfortable and quick for the driver. At the same time the combustion engine may be completely switched off at speeds of up to 156 km/h or 97 mph, being fully disengaged from the drivetrain when no further power is required. In this so-called sailing mode, cruising along without power, the drag forces exerted by the combustion engine and their braking effect are eliminated in the interest of lower drive resistance and fuel consumption.â€ If youâ€™d rather be a badge-carrying Global Warmer, then youâ€™ll be delighted that you can still buy a Cayenne Turbo, with a 4.8-litre V8 that generates a worthwhile 500bhp. Even this manages to return 27.6mpg, though. In all, there are five models in the new Cayenne range: Cayenne, Cayenne Diesel, Cayenne S, Cayenne S Hybrid and Cayenne Turbo.
