Auto Benchmarking Study Reveals More Lightweighting Opportunities With Steel

GenericCar_YellowBRUSSELS, 19 October 2015 – A study released today by WorldAutoSteel, the automotive group of the World Steel Association, showed a wide variation in efficiency among steel components in vehicles on the road today. The study, “A New Paradigm for Automotive Mass Benchmarking,” further revealed that when aluminium closure components, such as doors, bumpers, hatchbacks, and decklids, are compared to efficient steel components of similar size, the 40 percent mass savings currently accepted as a standard measure of aluminium lightweighting capability is not nearly reached. The study also showed that while use of aluminium may achieve mass savings at the component level, that mass savings is lost when an entire system is measured.

The study, conducted by EDAG International, Inc., uses the A2Mac1 vehicle tear-down database of approximately 200 vehicles along with a benchmarking methodology. The methodology uses statistical regression analysis to isolate mass-efficient designs and compare lightweighting.  Read the full story; download reports and infographics >>>
