A leaf using only 6kWh per day to do 20 miles. That's only 0.4 hp hours per mile, so I hope none of it is up hill. That is not a realistic number, otherwise we could get away with 5BHP cars, Do you remember those Mike, I rather doubt it? I assume the number comes from a constant 20MPH along a nice smooth flat road with no other traffic. If that is what is claimed I would like to see them prove it on the average city commute with everyone else trying to do 40! The same vehicle would probably be able to do at least 120 MPG on petrol, so the cost is not that much less is it, we must be very careful not to compare apples and pears. 6kWh is about the energy in 1 litre of petrol burnt in a modern engine so if we forget the tax petrol is cheaper. BTW my electricity is more like 16p / unit. They will have to tax electricity somehow to raise £20 billion at least from electric cars.
