Alumobility study: aluminum top hat provides automakers a lighter, sustainable alternative

Green Car Congress

Introduced at Automotive Circle’s annual EuroCarBody conference, the study’s aluminum top hat achieved 42% weight savings compared to the reference top hat of the current Audi e-tron electric SUV, which uses advanced (AHSS) and ultra-high-strength steels (UHSS). Additional details on the top hat study are available at.

MIT study finds materials risk exposure increases significantly with vehicle electrification

Green Car Congress

Now, a study by a team from MIT’s Materials Systems Laboratory, with support from Ford, provides insight into how electrification is changing vehicle composition and how that change is driving supply risk vulnerability. Modern automobiles are built with more than 2,000 different compounds comprising 76 different elements.
