"Built Ford Tough" really means something to the designers and engineers at the Big Blue Oval, which is why the new 2021 Ford F-150 has the only high-strength, military-grade, aluminum-alloy body in its class. In fact, it's been specially heat-treated to further harden the alloy, and selectively increased in thickness only where necessary in order to boost strength without adding needless weight. As a result, you receive a higher power-to-weight ratio than you would otherwise.Â
