Aluminum can reduce vehicle weight by 40% compared to only 11% for high-strength steel, allowing for improved fuel economy and performance without compromising safety. Aluminum absorbs twice as much energy in a crash as steel, and its use in key components maintains strength and stiffness where steel cannot. Studies show aluminum's weight reduction potential results in 2.7 more mpg or a 10% fuel economy improvement over typical vehicles today. While aluminum has a higher component cost, secondary weight savings offset much of the premium, making it a cost-effective material for automakers.
