Renault are starting to really push their Zoe electric car. It's an amusing
price, but massively subsidised by European governments (ie by you, me and
every other taxpayer).
Renault advertise it as 130 mile range but in the small print is detail
that the real world range is closer to 60 miles. But the interesting detail
is that you have to rent the battery. That will cost the driver £80 a month
for 7500 miles a year.
So that's 13p/mile just for the battery.
And my wife's boring old petrol car costs.... 13p/mile in petrol.
I'm struggling to see what makes the electric car a good idea.

Well say a 30 kWHr battery and M-F wage slave and a trip out at the
weekend 6 charges a week: 6 x 30 = 180 kWHrs @ 10p = £18/week, app
£75/month. Hum around 26p/mile.... Even charging every other day is
about the same as my diesel guzzler. B-)
With a 60 mile real world range the inablty to do the weekly shop
would kill it for me.
Remarkably (although I'm sure things will soon change), it only costs £10

Even so, the main problem seems to be that EV's are most use if you live in
the inner city - where you're least likely to be able to park in your own
driveway to charge-up.
(I wonder if anyone's collecting up car-full's of free electricity, taking
it home, and dumping it into their feed-in tariff?).
As your pricing example points out, EV's are *nearly* there, and the Renaul
t pricing deal will be enough to bring-in more early adopters.
I've also heard plans for retrofit conversions to existing street lighting
for add-on charging points. I suspect roll-out of public charge points will
soon become the choke-point for inner-city adoption.

I suspect Renault will get sufficient volume of sales now, with their "rent a battery" deal, to get governments to support a wider roll-out of subsidy deals, public charging infrastructure etc.
The beneficiaries are likely to be well-heeled 2nd car owners that have a well-defined niche for that vehicle (in fact rather like the car scrappage scheme of a few years ago).
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.
I've always thought that extra weight is a significant penalty when
climbing hills and when accelerating, but relatively little penalty when
travelling at a more or less constant speed on a moderately flat motorway.
That would tend to make the battery-carrying impact even more on the
stop-start/short range electric car than the fuel weight on long journeys.
Cars like the Fiat 500 have around 85kg of engine and transmission. They
carry 35 kg of fuel. Electric cars have more than double that weight of
battery. The Fiat manages around 70mpg, giving it a 540 mile maximum range.
The Nissan Leaf is inferior in every respect.
The Nissan costs £24k, the Fiat is about half that price.
You'd have to be an utter shithead to buy the Leaf.
I drove a Fiat 500 Twin Air over the Apennines last year. It was OK, coped
with the hills really well. Then again it wasn't lugging around batteries
weighing as much as three fat yanks.
It also got me to my destination. An electric car wouldn't have managed the
In the stop-start scenario they can (and do!) use regenerative braking -
recharge the battery with the motors instead of throwing the energy
away. That's what they are really good at - that and not having a
tickover burning fuel even when sitting still.
But back a step - the weight difference between full and empty on my car
is perhaps 50Kg. Out of 1500. So ~3%. I don't notice it.
