A report prepared for the Society of Automotive Engineers states that the maximum use of aluminum (420 pounds per car by 1985 is a realistic figure), could reduce car weight by 30 percent from 1974 levels, and increase average gasoline mileage from 13.4 to 20 miles per gallon. The weight reduction can be accomplished without compromising comfort and safety features mandated by law. The use of a single pound of aluminum in an auto part in place of iron or steel produces an immediate average weight saving of 1.5 pounds. This also allows the use of lighter structural parts and saves another 0.75 pounds. The weight reduction translates into 160 to 250 gallons of gasoline saved over the lifetime of the car. The greatest potential is seen in increased use of aluminum castings and even greater use of body sheet. The greater use of aluminum can also result in an eventual energy saving through recycling of the metal from junked cars. The economic motivation for recycling aluminum is five to eight times that for recycling steel.
