BMW is keen to offer eco-friendly options to the world and a decision has been made to assemble the electric cars at the Leipzig facility. BMW chose the facility for its flexibility and capability for increased capacity. Models like the ActiveE, an electric variant of the 1series, will be produced in limited lumbers up front and then the Megacity EV will be rolled out in 2013. While the assembly will be in Leipzig spare parts will also be built in Wackersdorf and Landshut while the Li-on batteries will come from SB LiMotive which is joint venture between Samsung and Bosch. Megacity will be a battery laden commuter and carbon fiber usage will ensure high economy courtesy of the low overall weight.
