It would be theoretically possible to have a small battery ("just a 60 mile/100km range, or even smaller) combined with a generator, but I don't know if markets would appreciate that.
This company Toyota started a pretty popular line of hybrid gas-electric cars, maybe 20 years ago, called Priuses. I think they sell pretty well. I see a lot of them running as taxis. The new ones can plug in and drive a few miles on the highway on pure electric before starting the gas engine.
Its called a series hybrid, there have been a small number of plug-in hybrids that used that design, they weren't successful in the US and are no longer in the US market. But that may not be anything particular about the technology; I wouldn't generalize from such a small set.
