They strengthened the frame which is good, and it appears Ford's new mantra is changing from 'Built Ford tough' to 'ECOBOOST ALL THE THINGS!!'
"The high-strength steel frame is the strongest in the F-150 lineup, while the military-grade, high-strength aluminum alloy is the main reason for the more than 500 pound weight reduction claimed in the new truck. The aggressive design of the body is inspired by Ford's long participation in off-road racing, such as the Baja 1000."
"Power comes from a second generation
3.5 liter EcoBoost V6 that will produce
over 411 hp, the output of the current 6.2 liter V8, while offering greater efficiency."
Needless to say, I'm a fan. I especially like what they did with the tailgate - it lets those driving behind you know that it's undoubtedly a Raptor, without giving the impression that your wife in the passenger seat is in fact your sister as well.
