As any hybrid, it is powered by two engines, a combustion and an electric one. But, as it is Porsche's tradition, the hybrid system has a difference: the electric engine is not beside the combustion powertrain, but between this engine and the transmission.
This is, according to Porsche, what allows the car to reach speeds of up to 132 km/h and a fuel consumption of 11.1 km/l. The electric engine also works as an alternator and recharges the nickel metal hydride (NiMH) battery that is placed in the spare tyre compartment. Summing up, the German automaker promises a V8 performance car with a four cylinder fuel consumption. Considering it is equipped with a 3-litre V6 from Audi with direct fuel injection and 333 bhp, this is quite an achievement. Soon in a Porsche dealer near you.
