Study: Aluminum could reduce vehicle body weight by 40%; cut fuel consumption by 10%

After analyzing 26 individual components in compact vehicles, the University of Aachen and the European Aluminium Association concluded that using aluminum in some automotive parts (illustrated by the graphic above) could safely reduce vehicle body weight by up to 40 percent, resulting in 2.7 more miles per gallon of gasoline burned or approximately a 10 percent reduction in overall fuel consumption. The study claims that the weight reduction potential of high-strength steel is limited to a mere 11 percent because nearly 40 percent of the 26 parts analyzed could not be made any thinner without severely compromising the vehicle's structural integrity. However, it was found that aluminum could be used to slash weight without reducing the vehicle's stiffness or hampering its performance. The Aluminum Association's Transportation Group says that this study, combined with other...
