Unlike a typical full hybrid model, in a parallel full hybrid system the electric motor is integrated into the drivetrain. The hybrid module sits between the transmission and the combustion engine where it docks to a decoupler. The heart and brain of the drive system is the Hybrid Manager: supplied with all the relevant information, it coordinates the combustion engine and electric motor to suit the current driving style. The 240-cell, 288-Volt battery with a 38-kilowatt capacity is situated in the spare wheel recess. A useful space-saving, because it minimises the intrusion into the luggage volume. With the aid of a special cooling system, its temperature is maintained at below 40°C.
One of the great benefits of the Cayenne S Hybrid is that it will ‘glide’ along the road without using the combustion engine – even at high speeds. Up to a speed of over 130 km/h, especially in relatively constant motorway driving, fuel savings can be achieved. Driving using just the electric motor is possible up to speeds of 50 km/h.
Fuel consumption/emissions* of the Cayenne S Hybrid: Urban in l/100 km 8.7; Extra urban in l/100 km 7.9; Combined in l/100 km 8.2; CO2 emissions in g/km 193.
