According to Christopher Macgowan, big cheese at the UK Society of Motor Manufacturers & Traders and the bloke who’ll get it in the neck if the upcoming London Motor Show is a flop, there will be two big reasons for electric city car fans to attend the event. Apparently two new zero-emission runabouts will be brought forth blinking into the light at the show. (That's zero emissions if you can ignore the filthy power plants that generate the juice). Anyway, we already have the bad and the ugly, let’s hope one of the pair of sparky newcomers is good.
