Fill it up for £1 from a simple compressor.

I can see you haven't put much, or indeed any, thought into this. £1
won't even buy you 10kWH of electricity. Presumably you are thinking
that this compressor will be electrically driven? Hence the most energy
you have in the vehicle for your £1 is likely to be 8.5 kWH at current
prices. One litre of petrol has approximately 8.5 kWH. Hence you're
filling the car with the equivalent of one litre of petrol, and you will
get about the same distance on that as you would in any petrol car of
the same mass.

I would guess that your £1 would take you anywhere between 30 and 60
miles at best. Hence achieving about the same distance that you would
from a petrol powered vehicle.

Where the *** do you buy a car that can do 30-60 miles on 1 litre of
petrol?

Sorry mindfart I was thinking in gallons. So in fact the expected
distance from £1 of air is about the same as from £1 of petrol which is
somewhere around 17 - 33 km.

And that shows that the actual 7 km per charge achieved by the actual
car is piss-poor and it's not that likely to hit 200km/charge as
claimed.
