I have a Cupra Born with a 58Kw battery and V3 spec.
Quoted range 240 miles. You can get the 78Kw but you lose a seat in the back - this has a quoted range of around 340 miles I think.
Pottering around you can get that and sometimes more - after one charge it told me the range was 290 miles - no heating or AC on.
Any motorway driving and then no.
Most I've got was 200 on a motorway drive and probably not going over 65.
It's a great car, lots of toys, nice to drive - but £41K - over priced (company car - saves me lots of money over the previous Golf GTE which was a hybrid)
My boss has a Polestar -2 years old and that always says he gets 250 miles on a charge.
If you have to do a lot of mileage EV's are not for you.
If mainly short journeys then they are good.
Of course - whether they are really as good for the planet as they say is another matter. The damage from getting the lithium for the batteries, the eventual hit taht will come when all these EVs batteries reach the end of their life, how the electricity is generated etc etc.
I am all for alternative fuels but do wonder if EV is the answer and not something else (hydrogen)
