First aluminum panels, now a magnesium liftgate as car designers embrace fuel economy
Fiat Chrysler Automobiles NV is turning to magnesium as the latest trick in the auto industry’s design tool kit to reduce the weight of vehicles and boost fuel economy in the face of rising emissions standards.
The Italian-U.S. auto maker is embracing the lightweight metal as a replacement for heavier steel in the rear liftgate of its 2017 Pacifica minivan, which arrives at U.S. dealers later this year.
