what benefits of replacing some of the steelin automobiles with plastic?

Answer 1

Less weight = better gas mileage

Less water used to process the material = less polluted water

longer lasting = fewer matierials mined in the future

More reliable = less expensive to repair, lower cost of operation

Plastic comes from US petroleum = value added within US

Answer 2

The major advantage is weight reduction, and that translates into much better fuel economy.

And, hard as it might be to believe, plastics can actually make a vehicle's occupants safer in an accident. They can do this by their proper use in critical crush areas causing the vehicle to absorb more of the energy in a crash which transmits less of the force to the occupants. And plastic interior parts are a heck of a lot better to bounce your noggin off than steel.

And, thank God, plastics don't rust.

Answer 3
