I agree with the point that it's more efficient to charge from the wall, but the genset is an acceptable trade-off if it's used seldomly (and, if possible, it's easily removed and left at home when not needed.)
The ICE is certainly an option (especially if the car is 4WD/AWD and thus can be electrified easily), but then you're in and out of your powerband. An 80cc or 150cc 4-stroke driving an Etek (especially if you can go with, say, a 72V drive system so you don't have to boost/buck your Etek to match) would be a lot more efficient, if not as clean. A biofueled diesel of equivalent power would probably be even more efficient, with noise and vibration being the inherent problems.
