I use my car every day but, now I think about it, I probably do about 5 journeys a month with a round trip of over 40 miles. Someone was using their head here. Trouble is Li-Ion batteries don't age well - irrespective of the number of charge/discharge cycles after a few years they have often halved in capacity (anyone with an old laptop will know what I'm talking about).
I'd love to see how economical this would be with a small capacity turbocharged diesel engine. The 1.3 Multijet Fiat unit that GM put in the corsa for example, no good for the North Americans but viable for Europe.
I think this is exactly the car GM should be making in 2009, instead of just churning out more Hummers, but I fear for how much money they will actually make from it. Those Li-Ion batteries alone wouldn't have been cheap.
