Thanks @kezo I’m determined to work out the true running cost (including charging costs – which most PHEV drivers on here conveniently ignore 🤔) when I get the car.
If I’ve worked it out correctly, it will cost me £2.60 to charge the 13.8kWh battery from 15% (which seems to be when the EV only running ceases) to 100%. Most of our local journeys are 30 mile round trips. If we do all of that in EV only mode and the battery is back down to 15% when we get back home, then that £2.60 equals 8.7p per mile. The BMW costs £4.50 for that same trip (15p per mile).
Longer journeys will be the acid test. I did a 60 mile round trip in the BMW today and got 52mpg. That’s just over 12p a mile. I’ve had a play with your 320 mile trip to get in practice 😂 . Assuming my charging and petrol costs, your 38 miles on electric cost 6.8p a mile and your 282 miles on petrol, using 6 gallons, was actually 47mpg, not the 53mpg stated on the computer, so 13.6p a mile. So for the total journey it was 12.8p per mile, which would be a saving of 2.2p a mile against my BMW on a long journey.
Unlike you, I don’t have a daily school run or commute, where the savings can add up to something meaningful, but my hope is that I will get enough of a saving to make the faff of having to charge it after each use seem worthwhile 😂
