Cars are becoming lighter now. Are more and more plastic parts used?
Automotive plastic parts for several reasons, first, because lighter, two is cheaper, and three is the development of science and technology, so that plastic can meet the requirements of the use of metals, to "plastic instead of steel" realm.
The lighter the car was, the more it was the pursuit of lightweight. The car is lighter and more fuel-efficient. Plastic parts are also used more and more, but not because of more light, but because of the pursuit of light, so use more plastic.
