The e1 and e2 are two lightweight sports cars that recall the Lotus 7, this time fitted to an electric drive. The models come from Germany, and are the result of the work of E-Wolf, the Saxony Lightweight Center and the Institute for Lightweight Structures and Polymer Technology at the Technical University of Dresden. Street-legal, the e1 is being introduced during the Frankfurt Motor Show. The e2 is just an idea at this time, and will arrive in two years.
The most remarkable features of the e1 are the light weight: 500 kg (1102 lb) and that it can only be driven by drivers that are no heavier than than 70kg (150lb, no comment). It uses a 110kW, quadripolar, liquid-cooled, AC induction motor (150hp) that propels the car to 0 to 100 km/h (62mph) in less than five seconds and gives the e1 a maximum speed of 230 km/h and maximum torque of 250 Nm (185 lb-ft). The lithium-ion batteries, distributed along the car's floor, weigh only 84 kg and use a signature ceramic membrane that separates the anode from the cathode, giving the car a range over 300 km (200 mi). Want one? The custom cars sell for €150,000.
