The most popular vehicle on sale in the United States is receiving a redesign for 2015. Featuring copious amounts of aluminum, Ford claims that the new F-150 is going to be lighter and stronger than previous versions. To ensure that their claims are accurate, they spent months torture testing the truck. By the time it rolls off the assembly line, it will have driven 10 million miles in testing. Ford documented some of their testing procedures on video.

The F-150 design team also torture tested the truck harder than they had on an previous truck. “We wanted to build the toughest, most capable F-150, while making it as much as 700 pounds lighter,” said Pete Reyes, Ford F-150 chief engineer. “We challenged the team to torture the truck harder than any F-150 before it.”

Some Ford tests are so extreme that a five-day period equals 10 years or 150,000 miles of abuse by the roughest customers.

Ford wants to prove to potential customers the toughness of the new F-150, which weighs 700lbs less. Ford sells a new F-150 every 42 seconds, and they do not want to make changes that affect that sales pace. We expect to see more examples of truck toughness before the vehicle goes on sale.
