Not really, midnight to 06:00, 5p kWh every night which equates nicely to 1p per mile fuel cost. I'll take that thank you.

In reality it does around 235 miles on a full charge dependent on speed more than anything else. It's no different to ICE cars which are quoted MPG figures which they never achieve.

^^ Indeed. The absolute maximum range that the dash shows on my current Tesla X (100 whatevers battery version) is 320 on a full charge. This is fiction. However, if I drive in a measured way, I have achieved 280 on mainly motorway roads, using cruise control and auto drive (gimmick) to Europe. Which we do often. We do a quick top up and coffee break in Brugge. That is OK. On the other hand if we went in an Audi Q7 diesel, we could do it with no stops at higher speeds and still have significant range left.

Not sure about mainland Europe but nothing to stop that design in the UK. I built a lotus 7 replica and it has open wheels, the same as a Caterham 7. Aerial Atoms and numerous other similar cars also have open wheel gaps.
The Coefficient of drag on a Caterham is about 0.7 though! it's slightly better than a brick!
Yes of course BUT the Q7 wouldnt have achieved the MPG figure in the specification sheet which is the argument here.

......If you are driving a V8 diesel or V12 petrol, then mpg is not at the forefront of your mind. 
I used to live in Switzerland and regularly did Zurich to London and vice versa in a Q7 on a single tank, not hanging about. Diesel is still unbeatable for real long haul driving.

Did anyone else notice the dearth of superchargers on that map around the Leicester area? Oh err!

I saw one of those in Bournemouth a while ago. Beautiful car. Bit pricey though!

My daughter is one of those with an EV (company car) and no off street parking. She lives in a flat on the main road through a suburb of Bournemouth. Fortunately I am less than a mile away and have ample off street parking so we had a charger installed and she charges from here. She regularly travels long distances in it, including into the wilds of rural Wales, but she absolutely loves the car and would never go back to ICE.
She's found that route planning is the key and rarely gets into range anxiety situations. She's happy to have a half hour break with a coffee and her laptop. In fact she she gets more work done on the road that way, rather than having to do it when she gets home.
So, one happy bunny at least.
I am actually the perfect customer for an EV: I rarely do more than 100 miles a week and always park at home. And on the rare occasions I go long distance I use my MX-5, much more fun than my boring Mazda3. They're just too expensive at the moment. But when the 3 needs changing, in 3-4 years, an EV is in my sights.

So which car are you talking about?
I've just pulled the stats off the MG website for the MG5 EV Estate that you highlighted and it's much longer than 6 hours to charge from 10 to 100%. In fact 10 hours at 7kw and of note is that is at a temperature of 25c

Quoting myself: I just heard on the radio that EDF are offering a tariff with free electricity on Sundays. For the mileage I do, that would mean free charging.
Tesla aren't the only ones making fast chargers, and it isn't as if there is a total lack of chargers in the area...
As they don't have a scale on their maps (rather dumb lol)- here's a google maps shot of the same area for those unaware of the distances involved... with a distance scale top left...
So within a circle measuring approximately 5km across contains 5 ultrarapid 150kw + chargers, 10 rapid (50kw-150kw) chargers, 5 fast (8-50kw) chargers, and too many to count without expanding the map further slow chargers...
I prefer Plugshare, here's their map...
https://www.plugshare.com/
To see for yourself just how many are in an area, go there and type in the town name you want... (if you hover over the marker, it gives you its details- orange is a 'fast charger', green is a 'slower' charger

Both, MG5 and BMW i3
That is true but you don't normally charge from empty to full every night. I only need to replace the amount of energy I use in a day. at 7.2 kW I can replace 216 miles during the 6 hours overnight, if I really wanted the full range I could start the charge earlier at 13.37p kWh giving me 1.8p per mile.
That is what I said,
It would not be difficult to just have motors built into the hubs, especially in the rear unsteered wheels and with a 4x4 configuration under electronic control then traction could be maintained without the risk of skidding, no need for diffs in axles or between front & rear so the potential is there once battery technology gets there.
AWD is already quite common in EV's (hub motors on the other hand aren't really that desirable- they already exist, but using them means more unsprung weight on the tyres- which reduces handling, and increases tyre wear...)
This is a list of some of the existing vehicles available here in Australia with AWD
(theres a couple of 4wd versions ie utes) coming very soon- either hybrids or full electrics)
BYD already has their prototype 'ute' (expected to be on sale later this year as a hybrid, and the full EV version in late 2025) was seen driving around Melbourne late last year- expected cost 'under $100k'- which isn't that bad considering its an actual 4wd, plus the cost of a new TDI Hilux is usually up around the$75-80k mark for the usual 'family' crewcab ute...
https://www.drive.com.au/news/byd-ute-prototype-arrives/
Many may scoff at 'some Chinese mob making a ute'- but BYD is actually a well established company, making EV cars since 2009, and trucks and buses since 2012 (we have been using BYD buses in Sydney since 2016!!!) and have outsold Tesla in Australia...
I suspect making a ute won't prove particularly challenging for them lol

Total aerodynamic resistance is (AIUI) drag coefficient x frontal area.
Despite the brick comparison, it probably takes less power to make progress in a Caterham, Westfield etc than the average modern supermini with hours of wind tunnel testing and computer modelling.

ICE cars currently have around double the range of a typical mid range EV - say 500 vs 250 miles.
Recharging is 5 minutes vs +/- an hour at a fast charge. Further issues:
- the cautious tend to refuel whilst there is some range left in the tank/battery - not run it down to the fuel warning light or 10% charge.
- as petrol tends have better availability than fast chargers, the residual capacity required before range anxiety sets in may be greater for electricity
- whilst both fuels are subject to efficiency losses with low temperatures, this is usually more pronounced with EVs.
- an ICE with 500 miles total range has an effective range of 450 miles. In winter ~zero UK temperatures could reduce range by ~10% giving an effective range of 400 miles.
- an EV with 250 miles total range has an effective range of 200 miles. In winter ~zero UK temperatures could reduce range by ~30% giving an effective 125 miles.

There are probably more chargers than conventional garages in the area - but:
- the average forecourt may have 6-12 pumps
- each pump is occupied by a car being filled for ~5 minutes
- not all chargers are fast chargers
- each charger is occupied for (say) 15-120 minutes depending on charge rate and kwh needed
No argument with that at all.
This is simply not the case, most EV's get to 80% in a maximum of 40 minutes and thats where you stop charge and journey continues.
Not sure of the point youre making here
I think you mean rapid chargers, fast chargers are the 7 kW units that people have at home I would guess better availability of fast chargers compared to petrol pumps but fewer rapid chargers than petrol pumps.
I suspect that if a petrol car was used for a 3 mile journey in winter conditions the downgrade of range would be similar. An EV can have heated the battery up and the car interior, defrosted the windows etc all before you start to use the battery range.
It's nothing like 30% on either of my EV's. My i3 drops from 145 in the summer to 120 in the coldest of days. The MG5 from 255 miles in the summer to 225 in winter.
And an amazing amout of data protrayed by people that really dont know. I have been a petrolhead all of my life until 8 years ago when I was converted to EV. I had some very nice ICE vehicles in the past but experiencing all aspects of EV's I would not go back. Not for environmental reasons purely the way an EV drives, the smoothness, the performance and the incredibly low running costs.

With my diesel I tend to only half fill the tank generally. As I do mostly short trips it doesn't make a lot of sense to me to carry 25-30kg of extra fuel with me everywhere i go, when half a tank will get me well over 250miles.
I only brim the tank when I've got a very long journey to make, and even then It would probably make more sense to re-fuel on the way.
I guess if i had an EV i would have to change my habits and try and keep the battery topped up, as it makes no difference in weight and is seemingly better for the battery.
