Electric cars use Kinetic energy which is generated through deceleration and converts it into stored electrical energy...sort of like reversing polarity on an electric motor to run it as a generator. Fine in stop start driving...useless on the open roads.
Hybrid has a small displacement petrol/diesel engine that essentially just acts as a generator (same as your Yammy in the caravan) to recharge the batteries. On a long haul, the petrol/diesel engine would be running a lot to try and keep pace. Another varriation of this is when the same engine actually over rides and runs the drivetrain.
FYI... on a recent 7000km trip through central Aust, across to QLD and back to SA, with 5 of us and a 99.9% luggage load we averaged for the whole trip 7.8litre/hundred in our AWD Captiva. Some of this was done in sand (Simpson), mud(
Birdsville Track) and crawling speeds (
Birdsville Track), all with the A/C running and not pussy footing either.
On the highway legs, sitting at a touch under 120kmph we were getting 830kms out of our "shot glass" 65 litre
tank. I can't complain about that.
Fab.
