During the 1970‟s there was a fuel crisis and so
the demand for more economical cars became greater, which led to changes in car
aerodynamics. If a car has poor aerodynamics then the engine has to do more work to go
the same distance as a car with better aerodynamics, so if the engine is working harder it is
going to need more fuel to allow the engine to do the work, and therefore the car with the
better aerodynamics uses less fuel than the other car. This quickly led to a public demand
for cars with a lower aerodynamic drag in order to be more economical for the family
