And the weight they are watching is that of future car models. main reason is the federal its auto safety government and pollution control rules. Make no mistake about it. The auto industry is facing an immense job these days. It is to meet the rules and still keep cars performing in a satisfactory manner.

MacDonald that explains Weight has a much more telling effect on small cars than on large ones. Generally speaking, each additional 100 pounds of weight results in a 0 4 mile per gallon decrease in fuel mileage for subcompact cars while a 100 pound increase reduces mileage in standard size cars by only 0.1 miles per gallon. The problem with weight, caused by things such as the federally mandated crash resistant bumpers, is going to mean another round in the material battle between plastic. steel and aluminum. structure components.
