Electric-powered rear and four wheel-drive variants of the Porsche Boxster E roadster have been showcased.

Porsche was demonstrating its prototypes to an audience of representatives from politics, industry, trade and research at at global forum for sustainable mobility.

Around a sporting circuit, the Porsche showcased the Boxster E concept; exhibiting the combination of innovation, performance and chassis responsiveness that is characteristic of the marque.

Thanks to its design as a mid-engine sports car, the Boxster is an ideal vehicle platform for conducting realistic trials with electric-drive systems.

The open-top two-seater car is very light, enabling the new components that are the electric motor, battery and high-voltage technology to be accommodated within the vehicle in a crash-proof way.

The Boxster E is an all-electric vehicle without any additional combustion engine on board. Propulsion is provided by two independent electric motors with constant mesh gearboxes that act on the front and rear axles.

These 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 vehicle electric power units. They also enable the two-seater to sprint to 62 mphin 5.5 seconds from a standing start. Its top speed, limited to 124 mphis achieved without any gear change at all.
