Ive got a Smart EQ Fortwo which has a 17.6kW battery that costs me £1.18 to fully charge and gives me 100 miles of range this time of year if driven with some anticipation and the higher brake regen switched on.

Whilst some people take the p... out of the car it gets used more frequently than any other car we have as it is absolutely the right tool for the job for any local trips.

With the price of petrol running at about £7/gallon it gives me the cost equivalent of about 590mpg which is a bit hard to ignore.
