The business case is set, now I just need enough customer orders to kick it off.
How many customer orders have they got for this? I can't see how there's a market for it - are there really people who have classic Astons tucked away in their garage, willing to hand over several hundred thousand pounds to strip it of most of its character? And to what end?I feel I should add, "Aston Martin obviously know what they're doing". But, I don't think they do.

Basically this, yes. A good modern power station is around 75% efficient at normal loading; a good modern internal combustion engine running at typical road load is around 25% efficient. Plus electric cars can regeneratively brake to recover energy which conventional internal combustion powered vehicles cannot.
Yes there's losses in the grid, charging losses, etc. but whilst there's a number of them, each one is fairly small. You can afford to lose 10% of your energy quite a few times when you have three times as much of it to start with. Plus of course for us the UK's energy mix is only about half fossil fuel these days and most of that is gas which generates far more energy per unit carbon emission than oil or coal.

60 litres of diesel is ~50kg. That's 2155 MJ. ~700kWh. Oil powered power plant is ~45% efficient. Leaves you 315 kWh. National grid loss is of the order of 10% (between ~3 and ~12 depending on final user voltage). So you have ~280 left. Li-ion charging efficiency is about 99%. Charge your Tesla S 2.7 times and you end up with >800 miles range.
So better, much better with a more efficient power station and less pessimistic losses.
I'm a big fan of new EVs. This thing seems bonkers though. For the miles it'll do, why bother with an EV conversion? Particularly when the original smelly noisy IC engine is so much a part of it's character.
[quote=Mr-B]Before I even read the article i was thinking this is too soon, and what does the bloke in charge think: "My concern is that we're too early into this,"
My concern here is especially being British is we start the ball rolling with media coverage of EV's & conversions with plenty of intensive coverage, a few protests, then the Government feel they have to prep a knee jerk response to curb the masses.
Before we know it some Politician overnight without due care or forethought will issue a law banning or costing any car pre EU6 compliant or non EV or such like & the classic/sports market will drop overnight & the british mentality will lap it up, get the publics attention to look as though they are reacting knowing we are all essentially sheep. Short-termism.
I can feel the roller coaster coming. Think diesel gate or immigration pre Brexit vote - histeria the public will latch onto & gain momentum.

It may as well just have a big decal on the side saying "Aston Martin Marketing Department".
I doubt the number of people willing to convert any DB4/5/6 would even make it into double figures.
Do Aston have a Heritage classification on cars like this - similar to Ferrari Classiche? If so, surely any conversion would surely destroy any provenance?

The motor and battery are supposed to weigh the same as the original engine and drivetrain, and put out the same amount of power, but presumably with considerably reduced range and long charging times.
So, what's the point?
These cars are unlikely to be driven very far. Even as an EV conversion they'll only be used as an occasional novelty. Is it possible that removing the engine and manufacturing and installing a new battery and drive unit is actually worse for the environment than simply continuing to put a small bit of petrol in it every now and again?
It just looks pointless, mis-guided and a bit tragic to me. Leave the poor thing alone.

Why don't they just do a limited edition of all of their greatest hits in EV form using new chasis?
Must be cheaper, would result in a better product and would save some pretty rare and special machines (which will be of immense interest in future years because of how short the petrol age has been) from being cannibalised.
Imagine a kid in 2060 laughing about how cars used to literally run on fire using fossil fuels dug out of the ground. Madness!
