If you read our previous 2015 Ford F-150 review, you know the truck is going to come with some interesting changes this year. Most notably, it will have a new military-grade, all-aluminum body that's 700 pounds lighter than the old steel structure. To prove the new truck is still tough as nails, Ford put it through a series of torture tests, which you can check out below.

Corrosion Bath

When testing F-150 in the past, countless high-humidity chambers and salt baths were used, but since aluminum does not produce red rust, Ford came up with another solution. In the video below, engineers use an acidified spray and simulate 10 years of exposure to the corrosive liquid. In the end, there are hardly any signs of degradation.

Seven-Channel Input

The next video includes Ford's unique "torture rack," which is designed to twist and shake the Ford F-150 in seven different ways - 24 hours a day for five days straight. This movement and the duration of time spent on the rack simulate what a typical truck experiences over the course of 225,000 miles. The rack also replicates the force real road surfaces put on different truck components.

Stone Peck Alley Paint Test

Even paint is put to the test when Ford performs its durability challenges. In the following evaluation, engineers take the 2015 F-150 to a special location in Romeo, Michigan, where they drive it 150 miles over loose gravel, and then another 150 miles over jagged scrap iron. The truck's oversized tires spray debris all over, so that gravel and fragments of metal hit the truck from every angle.
