New Study: Aluminum Superior to Steel to Drop Weight, Boost MPG

A new study shows that an all-aluminum vehicle can shed more than 40 percent body mass, boosting fuel economy by 18 percent when combined with secondary mass savings and other design changes. The study helps explain why car and truck makers are shifting away from steel to aluminum, and supports projections that aluminum-intensive vehicles – with aluminum bodies-in-white – will become more common in the marketplace with continued demand for better fuel efficiency.

The research, commissioned by The Aluminum Association’s Transportation Group, was presented at the Society of Automotive Engineers (SAE) World Congress during a panel discussion on advances in lower weight materials.
