Efficiency champion with coasting capability Porsche Cayenne S Hybrid

With the advent of the second-generation Cayenne, Porsche has introduced parallel hybrid technology and applied a comprehensive program to increase efficiency to the entire model range. Significant reductions in consumption were achieved by the eight-speed automatic Tiptronic S with auto start/stop function and wide ratio spread, thermal management for engine and transmission cooling circuit, electrical system recuperation and variable fuel cutoff, and not least by weight reduction and intelligent lightweight design.
The Cayenne Turbo, by way of example, is 185 kilograms lighter, thanks to the weight-optimised selection of materials and conceptual changes throughout the entire vehicle, as well as the active and light-weight all-wheel drive, in spite of improved product substance and safety. This is hugely advantageous to fuel consumption and CO2 emissions, as well as performance, agility and handling.
The Cayenne S Hybrid is the first Porsche production car with a hybrid drive. The primary engine of the Cayenne S Hybrid is a three litre supercharged V6 engine with direct fuel injection that generates 333 hp. The engine is coupled with a 34 kW (47 hp) electric motor, which can drive the Cayenne either alone or in tandem with the combustion engine. It also acts as both generator and starter motor. The hybrid module consists of this electric motor and a decoupling clutch between the engine and the new eight-speed automatic.
The hybrid system is completed by a 288-volt nickel-metal hydride battery (NiMH) under the boot floor, which stores the electrical energy recovered during braking and driving with a six-cylinder Cayenne S Hybrid engine.
It has the power of an eight-cylinder engine and significantly lower fuel consumption. With a total power of 380 hp, the Cayenne S Hybrid consumes just 8.2 l/100 km NEDC and CO2 emissions of just 193 g/km.
The Porsche hybrid drive also allows the realisation of additional efficiency potentials in higher speed ranges by “coasting” without combustion engine on motorways and highways.

This unique range has been met with an extraordinary response from the public and customers: Both in reader surveys and the APEAL test conducted by the renowned U.S. market research institute J.D. Power and Associates, the Cayenne is regularly rated first. The world’s most popular Porsche model in 2012 was the Cayenne. Up to November, 68,435 Cayenne cars have been delivered to our customers. With 3,133 vehicles sold, the Cayenne S Hybrid is one of the best-selling, powerful SUV hybrid vehicles.
