Not with a ****y 130 mile range they aren't; I get a 600 mile range
with
a dizzle C4.


I doubt many people actually need a 600 mile range. Few would drive
that
distance without stopping - especially in the UK.


I bought the long range tank for my car specifically to give me a
better
range than that for when I go touring in Europe. I won't do it
non-stop,
but I also don't have to buy fuel at motorway prices.

Also on those sorts of drives fuel stops are a significant drag
consuming
as much as a half hour every few hundred miles. With a long range tank
it's
possible to get much further with less stress. And of course there's
"fill
up in Luxembourg" syndrome. A fill there with a large tank can save
"quite
a bit" of money.


But it costs a lot (of fuel) to haul that weight of fuel around.


Yes harry, having to lug around 80kg of fuel is a real burden when
compared
to having to lug around 300-600kg of batteries in order to have half the
range (at best) of a petrol car.


It's all about energy density you see harry. I know that's a bit hard for
you to understand, but there it is.



No it's not.
There's energy recovery to consider.
I get energy back whilst descending a hill or slowing down.

There's efficiency of use.
The electric motor is around 85% efficient

1 Kwh of energy takes me around five miles.
Around one fifth of a petrol/diesel car.

It's the overall weight of the car that counts.
