2011 Porsche Cayenne S Hybrid

August 29th, 2010 - Posted in Sports Car

The highlight of this new generation is the world premiere of the hybrid Cayenne S with its highly sophisticated technical player and full parallel hybrid fuel economy in the new European driving cycle of just 8.2 litres/100 km (equal to 34 4 mpg IMP), which means that the CO2 emissions of just 193 g / km. The hybrid Cayenne S combines performance then an eight-cylinder economy of a six-cylinder-powered fuel much less.

These performance targets, not least the introduction of the new Tiptronic S automatic transmission with eight speeds with Auto Start Stop and a wide range of gear ratios, the thermal management of engine and transmission cooling, the recovery of the onboard network, variable engine cutoff and intelligent lightweight construction.

Taking advantage of these features and new technologies, the new Cayenne offers even more driving pleasure both on road and off-road, combined with even more qualities of everyday driving, comfort and supreme elegance. The all-new, sporting and elegant design of the new Cayenne model includes the 2010, even more closely in the global range of Porsche cars. The character of the Cayenne sports car is even more all angles, as highlighted in the form and design of the car so typical of Porsche are also clearer than ever.

Despite the increased engine output of 300 hp, fuel consumption in the NEDC driving cycle in conjunction with eight-speed transmission with Tiptronic S option is down compared to the old model of no less than 20 per cent to 9 9 ltr/100 km, equal to 28.5 mpg IMP.

In the intelligent interaction of the three-liter supercharged V6 engine and electric motor, the hybrid Cayenne S focuses on the maximum efficiency of the entire system. Depending on driving conditions, the vehicle reaches this target with a single drive unit operating by itself or with the two drives to work together. In this context, 34 kilowatt (47 hp) electric motor is of course the ideal partner for the engine of 333 hp compressor with its high torque at low speed. Together, the two drives to provide maximum system output of 380 hp and maximum torque of 580 lb-ft Nm/427 just 1,000 rpm, with the same kind of performance than the Cayenne S with its unit horsepower V8.

Both drive units are connected to each other by a separator clutch driven by the hybrid manager. Indeed, this clutch of separation is essential to run the hybrid Cayenne S or on its electric motor or combustion engine alone, or with both drive units that work together. Given a reserved, modest style of the car, for example in a residential area, allowing the driver to cover short distances on electric power alone and thus entirely free of emissions and almost no noise, leading at speeds up to 60 km / h or about 40 mph.

To ensure the rapid acceleration during the power off, the electric motor can however be used to provide an extra boost thanks to its stimulating effect. Intelligent separation of the clutch makes the transition between modes of conduct more specific hybrid discrete, comfortable and fast for the driver. At the same time the combustion engine can be turned off at speeds up to 156 km / h or 97 mph, is fully disengaged from the drivetrain when no power is needed. In this navigation mode is called, cruising along without power, the drag forces exerted by the combustion engine and braking effects are eliminated in the reader’s interest and resistance lower fuel consumption. source
