Porsche Cayenne: white hybrid on black wheels

At the IAA 2005, Porsche announced it would produce a hybrid version of the Cayenne before 2010 (Porsche Cayenne Hybrid). Two years later, at the IAA 2007, Porsche presented a functioning Cayenne Hybrid and demonstration model of the drivetrain.

Notable modifications to this car include an electric vacuum pump and hydraulic steering pump, allowing the car to function even when the engine is deactivated. A 288-volt nickel metal hydride battery is placed under the boot floor, occupying the space normally used for a spare tire.

The production version, called the ‘S’ Hybrid, was launched in 2010, with a 3.0-L petrol V6 linked with an electric motor to achieve CO2 emissions of 193 g/km. The S Hybrid was launched in the U.S. market in November 2010.
