Remember that EVs chug through power when at a static speed on a motorway because they regenerate nothing. So that 250 range might well be hopelessly optimistic. Which is a bit pointless for a GT.
Thanks, Peter, I'll watch that a bit later.Range was achieved on his test, but it was in eco mode... which kind of kills the reason for all that performance.

Was the test on a motorway at a static speed?
What's the range, Zep; 50 miles or so, or further?Interestingly my hybrid will do its pretty much its full range in electric at 70 mph. It’s the acceleration that eats the electrons.
Test in this case was in eco mode in the M.way... thats why I was surprised that c£13.00 only gave 84 miles extra... my old diesel did c57miles per gallon or 8 quid.Thanks, Peter, I'll watch that a bit later.

I noticed that, £13 for 84 miles of charge.Test in this case was in eco mode in the M.way... thats why I was surprised that c£13.00 only gave 84 miles extra... my old diesel did c57miles per gallon or 8 quid.

Out and about charging already more expensive than a 40 ish mpg ICE car……
I guess it’s much cheaper at home but it’s not a good sign.
Yes, adhoc charging can be very expensive. If you are a member of schemes like charge master or pod point, it can be free or about the same as at home (circa 14p per kWh). If you have an EV charge plan at home it can be as little as 5p per kWh, so about 1.4p per mile.
AgreeA dealer I spoke to recently is still expecting three forms of the car - 100% electric / hybrid / some form of ice (most likely a version of mc20’s v6) but didn’t have / couldn’t share any other details
Far from convinced about all electric cars, not sure how they work regarding heating etc. I always think about how it would have been with all electric a few years back when we were hit with a huge snowstorm. I ended up stuck on a motorway with a few hundred other cars as some HGV’s were unable to climb a section. I was there for 14 hours, it was -7 overnight. Was nice and warm in my petrol car. Cant imagine the carnage if all electric, freeze to death? Cars all out of power? Moving hundreds of flat cars might have been a challenge once the HGV’s moved.

An interesting question, so I did some maths.
A litre of petrol contains 9.1 kWh of energy. A petrol car burns about 1/2 a litre of petrol and hour when at idle. Petrol engines are around 35% efficient so that means that, assuming about a third of the waste energy goes to heating the cabin, around 2 kWh of energy is available to heat the cabin and if you had half a tank, say 30 litres of fuel onboard, you could last 60 hours. After 14 hours, you would still have enough fuel for 170 miles of driving, if you had the energy yourself.
For an electric car with a capacity of 82 kWh, half full, that would be around 41 kWh. Modern EVs use heat pump systems (most of them do anyway, and in the future all will) for cooling and heating, so to generate the same 2 kWh of heating would take approx 0.7 kWh in battery energy. So after 14 hours, you would have 31 kWh of battery left, or enough for 83 miles.
These numbers are quite extreme, but the electric car isn’t stranded, however it is certainly less resilient than a petrol car with current (geddit) technology. With 1/4 of a tank / battery both vehicles would probably be stranded. It will be interesting to see what the answer is in 5 years time.
Question: Why do we not measure electricity usage in Joules?
