Aluminum is lighter than steel. Automakers use it to cut weight, and thereby improve fuel economy and performance, or to add features without making cars and trucks disastrously heavy. The 2004 Audi A8L, which went on sale last month, is the third generation with an aluminum body.
Steel is the primary metal used to make most cars. In fact, the EPA suggests that almost 65 percent of the materials used to build the average car are a steel product. Most parts of the car that have to do with steering and suspension are made from steel. Parts of the body, wheels, chassis and frame are also made from steel. Steel is durable and flexible, making it a desirable material in car manufacturing because on impact it bends instead of breaking.
