Ford Motor Co. says the "military grade" aluminum alloys it will use to build its next-generation F-150 full-size pickup will be tougher than traditional steel yet light enough to give the vehicle a significant boost in fuel economy.
Introduced on Jan. 13 at the Detroit auto show, the 2015 F-150 is the first truck to adopt an all-aluminum body, which helped engineers shed 700 pounds throughout the half-ton truck. It also incorporates a new high-strength frame with 70,000-psi steel. Ford says the new structure will cut down the truck's fuel consumption, which, along with pricing, has not yet been announced.
