The use of high and medium strength steels in light vehicle construction increased by more than 60% from 1995 to 2008. Plastic and plastic composites, aluminum, and stainless steel also saw increased use during that period, while iron castings decreased by about 35%. Though there has been greater use of lightweight materials during this period, the overall material weight in light vehicles has increased by 376 lbs – from 3,694 pounds in 1995 to 4,070 pounds in 2008.
