After surpassing plastics in 2001 as third most-used material in the auto industry, behind steel and iron, aluminum rolls into 2004 with two major breakthrough programs - the Jaguar XJ and BMW 5-Series. The 2004 models are two of the most aluminum-intensive, mainstream vehicles in automotive history, continuing an expansion trend that has seen aluminum use double on cars since 1991 and triple for SUVs, pickups and minivans in the same time period. Jaguar employed Alcan Inc's Aluminum Vehicle Technology (AVT) to design a stamped-sheet structure that is 40% lighter than an equivalent conventional steel body, and 60% stiffer than the previous XJ. Mazda Motor Corp also advanced aluminum automotive technology by becoming the first auto manufacturer to apply friction stir welding (FSW) to the manufacture of aluminum body assemblies. Mazda's joining method uses friction to soften the aluminum and generate plastic flow to join the parts.
