Even for an all-electric car, it'd be nice to have a small gas engine to drive a generator to charge the batteries if you're too far from a socket.
Meanwhile every car I've ever had has suffered from window motor failure.
That said, the best vehicle in that style that I can think of, the Chevy Volt, does actually allow the engine to drive the wheels and has two planetary gear/clutch systems. On the plus side, the gas engine is expected to need much less maintenance than a regular engine that's used in a much wider power range.
I've owned a hybrid, however my current EV (Ford Focus EV amusingly) is just simply better in so many ways for how I actually use my car (commute/kids/groceries). We have a 2nd non-EV minivan for trips/hauling.
Charger availability is a decently available now, and charging standard adoption (i.e., DC Fast) is a game changer.
everyone on this site loves tesla and loves to think of their electric car as the solution to everyones car needs. but electric cars are still only viable as a 2nd car. a hybrid can be your only car
want to take a family trip sf to la? you will stop for gas once for 20 minutes and pay ~$60. want to take EV? plan for a long charging stop. want to fly? you’ll pay $100+/pp and rent a car when you get there. “most people” are going to see that EV has far less utility than a hybrid, usually at greater cost
Especially given the lack of complexity to electrics compared to hybrids, which are the worst vehicles on the road for complexity (inferior to a plain old lone ICE).
The only worse idea than a hybrid is hydrogen fuel cells. Some people like needlessly complex technology, I do not.
I can totally believe that it wouldn't work for you, but I'm not you.
Personally, I think Ford/Toyota's strategy is best. Any improvement in the pure EV space also impact hybrids. It's completely possible for battery tech to improve to the point that a hybrid option is basically no cost (or at a cost savings). As in, instead of offering a V6 or turbo 4, a Ford can offer a hybrid drive train at the same price as those engines, but with the better performance and fuel economy.
Also, keep in mind that Ford is a really a truck builder with a car division. The bulk of their profits come from F-series pickups and EV pickups are probably a long way off, but hybrid pickups are coming this generation.
I think Nissan and GM are capitalizing on the fact that Ford and Toyota are sitting back, watching how the market evolves. But so far, neither the Leaf, Volt, nor Bolt have earned any any real ROI.
