Mississauga, Ontario – Porsche AG has released information about its Cayenne S Hybrid, which will debut next year.  The new vehicle uses a parallel full hybrid design with the electric motor between the combustion engine and the transmission.

Porsche engineers have been able to drive at speeds up to 140 km/h without using the combustion engine. The Cayenne S Hybrid can coast at highway speeds without the gasoline engine on, greatly minimizing emissions and fuel consumption. The company said this differs from current hybrids, which deliver their benefits mainly in city traffic. It can also travel up to 1.9 km on battery power alone.

When it comes to market in 2010, the Cayenne S Hybrid is expected to emit 20 per cent less CO2 than comparably powerful combustion engine vehicles. With acceleration of zero to 100 km/h in just 6.8 seconds, the model delivers V8 performance with four-cylinder efficiency.

The Cayenne S Hybrid uses a supercharged Audi 3.0-litre V6 engine with direct fuel injection, producing 333 horsepower and 324 lb-ft of torque. It is mated to a 52-hp, three-phase electric motor that produces up to 221 lb-ft of torque and also acts as an alternator. The combined units are mated with an eight-speed automatic transmission and a maintenance-free nickel metal hydride (NiMH) battery that fits in the spare tire well.
