Yeah, I think normal hybrid or pure ev is the way to go, depending on how you use the car and local charging availibility on your normal long distance journeys. A plug in will probably either be used as a pure petrol or pure EV 95% of the time for most users. The higher cost of an EV needs to be offset by more distance driven per year, especially the first years when depreciation is high.
Petrol prices will no doubt continue to increase faster than electricity, been averaging +8%/year the last five here and an EV has a comparable consumption to 1-2l/100km in petrol equivalents, so in the long run(over the vehicles expected service life) ev should come out cheaper since there so much more energy efficient, and 1kwh of electricity is a lot cheaper than 1kwh of petrol(.11 L). Petrol is ~250% more expensive than electricity per kwh here.
I think the E-Niro seems like a good car and it is one I want to test out more thoughly when I'm going to replace my car. Don't like that it's a suv though.
