Lighter vehicles mean less fuel consumption, reduced emissions, and improved performance.
In fact, good aluminum designs can actually improve safety. Plus, aluminum can give cars better acceleration and braking, improved handling, excellent durability, and ease of repair. One-third the individual parts are needed, too.

Research has demonstrated that aluminum performs as well or better in a crash than conventional steel-structured cars.
