Porsche Boxster E Prototype (2011)

Porsche Boxster E is a sports car concept exhibiting the brand’s characteristic combination of research and driving pleasure. The Boxster E, with one electric motor each on front and rear axle, runs on purely electric power with four-wheel drive and is equivalent to a Boxster S in terms of driving dynamics.

Together with two other Boxster Es, in which an electric motor drives the rear wheels, Porsche Boxster E Prototype is being used to explore the everyday practicality of all-electric vehicles and how they are used, especially in terms of driving and battery charging.

Porsche Boxster E is an all-electric vehicle without any additional combustion engine on board. The Boxster E features all-wheel drive without mechanical transmission of power. To ensure maximum driving stability and traction, a central electric control unit looks after the synchronisation of the two electric motors and controls the drive torque distribution to the front and rear axle.

The two electric motors on the Boxster E develop a total power output of 180 kW and a maximum total torque of 540 Nm at a maximum engine speed of approximately 12,000 rpm. That means that the two electric motors in tandem deliver significantly higher drive power than what is available from present day hybrid vehicles’ electric-power units.

The two motors enable the on the Boxster E to sprint to 100 km/h (62 mph) in 5.5 seconds from a standing start. Its top speed, limited to 200 km/h (124 mph) is achieved without any gear change at all – whether automatic or manual.
