BMW launched the i3 either as a full electric vehicle or as a range extender. Any i3 is cool (or at least quirky and unusual), through a combination of its boxy, upright shape, its interior that appears to have been designed by Zen buddhists (if specced right) and surprisingly enjoyable handling. The range extender has a 647cc straight-two motorcycle engine that gives the latest i3 REx a total EPA range of 200 miles.
