The big problem here is we need a hybrid stage in between.

I have a hybrid now, it's still a conventional powertrain, and it's not chargeable. That's not exactly what I want, but it's what I could get.

I want a fully electric drive train hybrid with around 100 miles capacity on the battery, then a generator that's big enough to keep it running if the battery is drained.

100 miles gets you through the average day without having to use gas.

An electric drive train turns your engine to a generator that runs at a fixed speed and is more efficient. It also massively reduces the complexity turning into a system more like an EV.

And, if I go on a long trip, the car still gets me to where I'm going without charges (unless I choose to so I can save gas).
