The driver has a great deal of influence (positive or negative) on the
gas mileage a given vehicle can deliver. My Toyota Tacoma pickup (4
cylinder, 4 speed automatic - a concession to my aging body) typically
delivers 1-2mpg better in-town when I'm driving versus my wife. My
typical mpg is 21+ in-town. Highway mpg has an inverse relationship
with the speedometer. 60mph delivers close to 28mpg; 70mph drops to
24 or less (actual speeds from two GPS units not the pathetically
inaccurate speedometer - note that the odometer is VERY accurate: it
controls warranty and what the factory may have to pay for).

It is also possible to make a 100mpg gas/diesel car however
the designers must work with a different weight/power ratio
requirements - which would prevent the use of a conventional
steel body. A United Kindom company, Axon (1), has taken
this design challenge route and it has built a 100 mpg
prototype car - it uses a carbon fiber body similar to
the Indy 500 race cars to keep the weight down and protect the
occupants. The cost to run the Axion prototype car would
be 100 miles/ $.60. which while only a 2 seater would be
about half the cost of running either the Chevy Volt or the
Nissan Leaf. The prospects of the next generation of
cars using carbon fiber has probably steel workers shaking
in their boots....

Cars are made with cheap sheet steel. If the steel companies had any sense
they would get into the plastics business.
If batteries improve greatly, it may be possible to remove the IC engines
from a Volt and be pure EV by installing improved batteries and maybe a new
ecu.

The Aptera uses an injection system like for completing
the unner core of a surfboard.
Hit it with a big hammer, doesn't faze it.

Carbon fibre. Don't think so. Doesn't lend itself to mass
production. Hence many of the problems with the Boeing Dreamliner.
