Building the F-150->ke423, America's best-selling truck->ke242 for 37 consecutive years and best-selling vehicle for 32 years, is not an easy task, and Ford->ke31 knows it must raise the bar with each new generation or facelift.

The Blue Oval already did that in 2014 by gifting the 2015 F-150 with an aluminum-alloy body, a benchmark in the truck industry, but lighter sheet alone won't cut it. The new F-150 needs to remain tough and become more capable, and with the new CAFE regulations just around the corner, more efficient.

The brand-new 2.7-liter EcoBoost V-6 might just be enough for the job, but with no official performance and consumption figures in sight, we can only speculate about its capability to take on the Ram 1500 EcoDiesel, the most fuel efficient light-duty, full-size truck you can buy nowadays.

As far as toughness is concerned, Ford invested a lot of effort and money into testing the new truck by putting it through a series of grueling trials. The 2015 F-150 endured both extremely hot and freezing temperatures, got its body and chassis twisted for days, took corrosion baths and had 55-gallon drums dropped into its bed over and over again.

While some of these tests aren't exactly new, Ford did develop new ways to test its trucks. Among its new torture equipment there's a special rack that twists and shakes the vehicle seven ways simultaneously, with forces stressing both the frame and the body. And that's just one of the extreme tests the new F-150 has been subjected to, with nine more available below.
