The PHEV variants of the new Porsche Cayenne, the Turbo S E-Hybrid and Turbo S E-Hybrid Coupé, are the most powerful versions of the luxury automaker’s popular SUV.
The PHEVs draw 500 kW from a four-liter V8 engine coupled with an electric motor that is integrated into the eight-speed Tiptronic S transmission. Both the standard and coupé models accelerate from 0 to 100 km/h (62 mph) in 3.8 seconds and reach a top speed of 295 km/h (183 mph). In comparison, the Cayenne Turbo, which features the four-liter V8 without an electric motor, accelerates from 0-100 km/h in 4.1 seconds, with a top speed of 286 km/h.
The electric motor is located between the engine and the transmission. The engine and motor are interconnected via a separating clutch inside the hybrid module, referred to as the Electric Clutch Actuator. In E-Power driving mode, the electric motor can, on its own, propel the vehicle up to a maximum speed of 135 km/h (84 mph) and for up to 40 kilometers. Drivers can also utilize the electric motor in the other modes for an additional power boost.
The 14.1 kWh Li-ion battery is installed underneath the trunk floor. Owners can charge the battery in 2.4 hours with the standard 7.2 kW onboard AC charger when using a 400-volt connection with a 16-amp fuse. Charging takes six hours with a conventional 220-volt home charger.
