For the past twelve months I've been testing a Nissan Leaf, the all-electric motoring solution. Surprisingly, not only is it supremely quiet and economical, charged from my home port, it is fast, comfortable and very refined. In fact, it feels like a small limousine, considerably more refined even than an equivalent Audi A3 or VW Golf. I would buy an electric car in a heartbeat if it weren't for one snag: Range.
