Honest question - just how much range would be acceptable for you? I occasionally think about this and I've got two figures as we're a two car family.
I've been thinking about this. The first thing I will say is that my usage profile is not typical of most. I accept this, but at the same time, I buy cars that work for me not others so for me personally, it's very relevant.
My car usage is split into three main areas
a) Local running around
b) Day trips
c) Airport runs and long road trips
For a), a BEV would be absolutely ideal. I've said a lot before that if it wasn't for the fact we ordered it new, its still pristine and it suits our needs I'd have an electric MINI tomorrow. I am not anti BEV. I'd love a BEV as part of my car 'fleet' because it's interesting and fun and I like cars and tech. I also love refinement and silence and what does this better than a BEV? Nothing. So, for a), an electric MINI would be absolutely perfect. The cost saving is a non issue - there is no material cost saving between the petrol Mini and the BEV Mini. It costs very little to do 5k a year around town in a petrol Mini. So, it's purely about the interest side of it and the way it would drive.
For b), we do this as often as we can - we'll often go out for the day and drive perhaps 100-150 miles visiting places, scenery, etc. I think this too would work with a BEV, but I'd be less inclined to do it in an electric MINI and would therefore want to use my main car. Which brings us on to..
c). This is a big part of what a car does for us. We love massive road trips and do them whenever possible - which isn't much at the moment with the current situation. Often in Europe or further afield. For example, on my last trip to Europe I jumped into the car in Munich and drove to Venice in a single day. The traffic was bad, stopping opportunities were not quite what you'd expect and I was incredibly glad of the enormous tank range of the 540d I was driving. Where to fill up or recharge just wasn't on the radar and I was glad of that. Many of our trips include days where will drive perhaps 400-500 miles in a single day. Sometimes, this would coincide perfectly with a stop for lunch and a recharge of the car but not always and it isn't convenient to have where and when you stop dictated not by your choice but by the requirements to charge. It is this area where I am most concerned about the BEV future. I'd suggest that more than 50% of the miles I cover are in scenario c). Many people rarely do significant trips but I do and I really enjoy doing them - it's why I drive the 530d because it is almost tailor made for that. So, obviously, any car I replace the 530d with is also likely to be particularly suitable for this sort of driving. And BEV isn't there yet. And neither is ample charging facilities at places like airports - it is 230 miles to Heathrow. I fill up at home, I drive to the airport, I leave the car there and when I get back I can get straight in and drive home without needing to think about having to charge the car first. This is particularly useful if you have a late arrival. It's just so convenient. Well, as convenient as it can be living a 4 hour drive from the airport
So, really, what I'd ideally like to do is diversify my car fleet to include a BEV for local journeys and a decent ICE for long distance stuff. Ideally I'd have another ultra refined powerful diesel but the universe hates these now. But there is a ticking clock on being able to do this even though for many people it's the right scenario - if we didn't have this ridiculous ban idea looming lots of people would probably naturally move towards a BEV for town and an ICE for distance which would make significant inroads into the city centre air quality issues (and on the open road, diesel becomes very useful as it emits much less CO2).
I'm also drawn to the idea of a plug in hybrid. But range becomes an issue here, too, as manufacturers seem intent on fitting tiny fuel tanks. The 545e - a 390bhp twin turbo petrol straight six - has a fuel tank almost half the size of my 530d. Great.
