So there’s hype, buzz and then a mix of those with reality when you talk about luxury and conscientiousness. Porsche has taken an interesting venture into the Hybrid fray with no different an approach than all of their other engineering (well, let’s say nearly all). The 2011 Cayenne Hybrid is amazing: Porsche performance with a green halo! So what makes this one tick?
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.
And for a little more techie speak, what makes the Cayenne Hybrid work so well? The parallel full hybrid system also comes into its own when driven at higher speeds. Without drive power needed from the engine and electric motor, the gasoline engine is automatically disengaged from the drivetrain and shuts off: The Cayenne S Hybrid continues to “coast” along. Engine drag and the associated deceleration effect are eliminated, and efficiency is increased.
The “e-power” function expands the range in which the vehicle can be run solely on electric power. The throttle map is adapted so that the combustion engine is engaged later than when in “Normal” mode, depending on performance requirements. This function is activated via a button on the center console.
All things considered, this is what it comes down to: More dynamic. More powerful. More efficient. Keep that in mind if you’re already been by to drive the completely redesigned gas Cayenne. This Cayenne hauls, at a whole new level!
