In July 2010 Porsche announced that it will be building three electric-powered Boxster test cars. “We will definitely be offering electric sports cars in the future,” said Michael Macht, the
President and CEO of Porsche AG. “But such a concept only makes sense if it offers performance and a cruising range comparable to that of a sports car today.”
In February 2011 it was announced that road tests with the Boxster E test cars are starting. Two cars were equipped with electric motor on the rear axle, and one car with motors on both axles making it the first 4WD Boxster. Using Porsche's language, we could say it was a Boxster 4E. Power was provided from a 29 kWh battery pack and the NEDC range was 107 miles / 170 km. The 2-motor Boxster E accelerated to 62 mph/100 km/h in 5.5 seconds despite its ~1600 kg/3500 lb weight. As the car had no geabox (just fixed ratio gear), the top speed was limited to 124 mph/200 km/h. The maximum engine speed was ~12,000 rpm. Considering the electric motor provides maximum torque virtually from first crank and you can go to top speed thanks to high-rpm motors without changing the gear - the emotion is rather amazing. With two motors the efficiency is increased as more energy is recuperated during braking. As electric cars are quiet, Porsche engineers designed an Active Sound Design system.
