By using aluminum in lieu of heavy steel--the traditional metal used to build a
car's body--manufacturers can reduce a vehicle's weight by as much as 45%, says
Zaluzec.
A recent Forbes article looks at aluminum's use in automotive applications and notes that by utilizing aluminum instead of steel a vehicle's weight can be significantly reduced. Low weight vehicles burn less fuel and produce fewer tailpipe emissions-both great environmental advantages. The article also highlights the importance of a multi-material solution, saying collectively aluminum and other low weight materials can help vehicles achieve an additional 20-30 miles per gallon.
