Seems like its not only about getting greener but also about the race for optimal performance; the RnD department at Porsche is presently testing an electric prototype of the Boxter in the streets of Stuttgart. After hybridization, it's all in.
Technical : The prototype uses 240 electron-powered ponies from motors attached to front and rear axles to give it all-wheel-drive sure-footedness and the ability to go from 0 to 60 miles per hour in 5.3 seconds. It packs a 29-kWh battery pack, which should give a solid 100 miles of low-CO2 uber-mobility per charge. All of its electro-tech is said to be sourced from its Volkswagen parent.
