Use of Aluminum in Automobiles-Effect on the Energy Dilemma

Abstract

<div class="htmlview paragraph">For a variety of reasons, cars have been getting heavier. A standard-size Chevrolet, for example, weighed about 3,700 lb in 1963 and 4,600 lb in 1973. Since there is a direct correlation between vehicle weight and gas mileage (EPA figures show an average of 24 mpg for a 2,000 lb car vs 11 mpg for a 4,000 lb car), weight reduction becomes an attractive means of increasing gasoline mileage. Also it can often be accomplished without compromising comfort and safety features.</div> <div class="htmlview paragraph">To help cope with the energy dilemma, more efficient use of gasoline in cars is needed. Aluminum, with a proven track record in weight reduction in cars and all other transportation vehicles, offers an ideal solution to auto weight problems.</div> <div class="htmlview paragraph">Immediate primary weight saving of 1.5 lb can be obtained by substituting a single pound of aluminum in place of auto parts made of traditional materials. This saving also permits use of lighter structural supports-again adding to the weight saving.</div>
