Here I am looking at the new kuga to change and have decided NOPE.
Having had mine for nearly two years now, I'd say it depends on what you need, how you use it, and the car itself.
It's 6°C here atm, but my battery range indicator is showing 48 miles and realistically I'd expect to see 35-40 of that, even in this temp.
I only drive less than 20 miles normally, so easily enough to cover by EV only at £0.07/mile.
I will need to go 100 miles tomorrow, which will reuire some ICE at £0.13/mile.
But I'll partially recharge before I come home again.
My '71 plate usually sees around 65-70 miles EV (£4.86 with regen), and 25-30 on the ICE (£3.90).
That's £8.76 against my old diesel Jag's £22.00.
I'm fortunate in that the potential saving isn't why I bought the car.
But I record it anyway and I'm aware of its' costs; the PHEV is still ridiculously cheap (to run at least), if that's a factor for you.
Last month was quite an expensive month for me, but it was still achieving 49 mpg.
I understand (I don't know, but) the latest Kuga PHEV is a little better on range and cost.
