My EV is virtually 6 months old, and as is always the case with my 'big car' has covered minimal mileage- currently 1,673 miles.
I may have dodgy calculations, but according to my home EV Charger electric meter has consumed 492 kWh @.249pence per KWh. That works out at about £122.00. In that time I have only needed to public charge a couple of times, so absolute worst ways £150 overall. By contrast my previous Ghibli Diesel would have cost over £400.00.
With the Genesis brand I have five years free servicing, with collection and delivery to my home on a transporter and courtesy car always loaned, I have a full five year warranty with the same conditions, and thanks to a tie up with Ionity (albeit they don't have a massive charging network) a subsidised 50% discount rate which when I last checked meant I could charge at the same rate as at home, and their chargers are I believe the fast 350 kWh units, which for me means 20 to 80% in 20 minute's.
Currently at least until 2025 I pay no RFL, or Sadiq Khan's rip off Congestion Charge, and I'm safe for a good long while with the ULEZ as the goal posts would have to move considerably before EV's get included!
The down sides are clearly if you don't have your own home charger, and are regularly doing high mileages. On a full charge depending on the outside temperatures- that as most know now makes a big difference to range, could get a realistic motorway range of 250 miles, without running the batteries too low. I will be in Harrogate in a few months for a few days, so from London I will only need charge at my destination.
So dependent on use, if your reliant on regular public charging, perhaps things need to improve, as I have discovered finding vacant working fast chargers can be a problem, things aren't there yet, but for light use you can save a considerable amount.
As for my car, I have said before, in a history of owning Jaguar's and a Maserati (an excellent car), believe it or not the Genesis Electrified G80 ranks as the best!
