Porsche said it has started road tests of an electric Boxster, the first of three electric variants of the sports car model.

“The Boxster E models will be our moving laboratories that will help us solve the practical problems of electric mobility in the way customers expect of us,” said Porsche CEO Matthias Mueller.

He said Porsche engineers were especially interested in how the car handled on the road and how its batteries would be charged.

The test drives took place in Stuttgart as one of eight German pilot projects designed to test and develop electric vehicles and an electric chargin infrastructure in the country.

The mid-engine Porsche Boxster model is a relatively light, open two-seater sports car that is well suited to test new electric-vehicle technologies, Porsche said.

The carmaker will offer the Boxster E with one or two electric motors.
