you can use your car as a backup generator.

One concern would be when you *need* AWD, you'd need to
have battery power. A long trip in the snow could drain
the battery before you were out of the snow.

All electric locomotion does seem to make more sense than trying to
split power with two engines.
Although, I saw a Volvo XC90 (a full-size SUV) with carpool stickers
and thought it was fraudulent. Read a little more and was intrigued.
Volvo's hybrid system is to have a gas engine power the front wheels
in a traditional FWD design. They took the driveshaft out, put the
battery there, and put an electric motor in the rear axle. When you
need AWD, the battery kicks in. When you're running on all electric,
the ICE turns off and the car is RWD. Wonder how people will react to
a car that could drive alternately from the front or back wheels?

So no onboard power generation for the electric motors?

I believe some electric vehicles might use things like regenerative braking & such to put some charge back into the battery, but as far as
I know, I don't think they have anything that provides more significant energy generation than that.

Hmm, OK, so obviously there's no generator attached to that gas engine...

Couldn't the car charge the battery when the gas-powered part is
being used?

I don't remember what vehicle was being discussed, but I've heard of
some that use electric motors to drive the wheels, and the gas engine
is only there to be a generator to generate electricity when the
battery charge is too low.
Moondog wrote to poindexter FORTRAN <=-
The only advantage I see to having the gas engine inline with the
electric motor is it's easier to spin up the gas engine using the
electirc motor torque rather than putting wear on your starter.

The so-called "serial hybrid", there the electric motors do all the drive work and the gas engine is just there to generate electricity, just like in a diesel electric locomotive. This was talked about as far back as the 80s, and it was suggested a smaller gas engine could be used, because it can run under optimum conditions (power, RPM, etc) more efficiently than having to handle varying loads at different RPM.
But the "parallel hybrids" like the Prius seem to be the more popular choice, which must have more mechanical complexity to combine the drive power of both electric and gas mechanically.

I don't know, I assume it'd have to be able to split gasoline power
between the generator and the wheels to maintain AWD, instead of
going gas-only and charging.

I suppose the parallel hybrids do seem to be more popular. One serial hybrid in the US was the Chevrolet Volt, and I heard Chevrolet has discontinued that model a year or two ago. I thought it was odd to
hear they discontinued it.

Yeah, I think that confused the buyers. The Chevy Volt was one, and
the BMW i3 with the range extender - both sold pretty well, though.
I wonder if a used i3 might be a cheap deal, would expect BMW
replacement batteries to cost an arm and a leg.

Hmm, I wonder why, in this era of increasing use of electric cars.

Chevrolet has another car called the Spark, which is a fully electric car.
