Typical efficiency of an automotive drivetrain/engine assembly is 17%-22%, so that 14-16% efficiency figure that includes power used by accessories seems reasonable.
Where does the energy go? Mostly to lost heat. Ever notice how cool an electric motor runs
when compared to an internal combustion engine? That's efficiency in action!

>Not all of the fuel that is put into a car's fuel tank is used to move the car down the road. In fact, only 14-16% of the energy is used for that purpose. The rest of the energy is lost to engine inefficiencies or used to power accessories.
