It would be nice, but there is literally only so much energy
in a gallon of gas.
The best and easiest way to get better gas mileage is to
have a lower aerodynamic profile, and less weight.
So Volkswagen went that route.
Regenerative braking helps a bit as well.
The only car built by a major automotive group to break 200 mpg
was the 1 litre proto type made by VW as a inline 2 seater.
VW 1 litre concept car gets 282 mpg
The fuel systems already are near there maximums.
Our best bet is to make a car powered off heavy water if they can get
the kinks worked out.
Cold Fusion experimentally confirmed
The US navy SPAWAR facility has duplicated it as well with a liquid
vs. solid active element.
