What is it?
Some will call it sacrilege, others progress. Whatever, it’s hard to downplay the significance of the all-electric Porsche Boxster E.
Officially, the new two-seater is just a prototype, created by a small team of Porsche engineers to support an electric mobility program sponsored by the city of Stuttgart in Germany.
But it’s no great secret that beyond its efforts to champion the city where it is based, Porsche’s long term goal is to produce a plug-in sports car to rival the likes of the Tesla roadster.
The silver and orange liveried prototype we’re in is one of two rear-wheel drive versions of the Boxster E in existence right now. It’s described as a packaging mule, painstakingly pieced together at Porsche’s Weissach R&D facility to test the zero emission roadster’s electric motor, battery system and all its associated wiring and ancillary systems.
So out goes the standard mid-mounted horizontally opposed six-cylinder engine and gearbox. Taking its place low down behind the cabin is a liquid cooled lithium ion battery pack. Consisting of 340 individual cells, it provides energy to an electric motor mounted within the rear axle assembly underneath the Boxster E's rear luggage compartment, which retains the same capacity as the Boxster.
Developed by Porsche parent company Volkswagen and also used in the Golf blue-e-motion, the compact electric motor delivers 121bhp at 12,000rpm. To put that in perspective, the Boxster’s 2.9-litre powerplant dishes up 248bhp at 6400rpm.
Porsche claims a range of 106 miles, with a recharging time of eight hours on standard 240 volt mains.
What’s it like?
Turn the key – yes, it’s still located on the outer edge of the dashboard - draw the familiar looking gear lever backwards to place the gearbox into drive, apply a modest amount of throttle and the Boxster E glides away with the sort of step off urgency you don’t get in the standard Boxster. With 199lb ft of torque – or just 15lb ft less than its more conventionally powered sibling develops at 4400rpm - available from the off, it scoots away from the lights with real enthusiasm.
