Aluminum began gaining wider use in vehicle manufacturing in the 1990s when Audi launched the aluminum-bodied A8 to reduce vehicle weight compared with traditional steel designs. To offset the additional weight from its Quattro all-wheel-drive system, Audi developed the Aluminum Space Frame (ASF), allowing the first-generation A8 to weigh about 500 pounds less than a comparable BMW 7 Series. The lighter structure improved handling, fuel efficiency and performance. The success of the A8 later encouraged automakers including Ford and Jaguar to expand aluminum applications, reinforcing aluminum’s growing role in vehicle lightweighting, corrosion resistance and recyclability.
