Although US customers will have to wait almost two more years before the next-generation Ford Ranger goes on sale, we're learning more about the new truck with each passing day. In the most recent spy shots, we got to see three different Ranger trims parked alongside each other. Now, Ford has revealed new information about the Ranger's grueling durability tests. After all, the new Ranger is a global pickup that will need to perform well in no less than 180 markets. The latest information also shows the Ranger tackling various torture tests, and many of them look brutal.

Already, the new Ranger has covered around 6,200 miles of desert driving and almost 390,000 miles of off-road durability tests at maximum load capacity. In total, it's covered the equivalent of over 775,000 miles of customer driving.

Ford's engineers not only get behind the wheel but also put the Ranger through hours of computer simulations to gauge how the truck performs.

"Computer simulations have helped us speed up development, while lab testing has helped us refine and test specific components - but there really is no replacement for real-world testing to really see how it stands up to years of customer use," said Chief Program Engineer John Willems.

As with the new F-150 Hybrid, some of the Ranger's durability tests are so harsh that robots have had to replace humans in some of them. As for the shots of the camouflaged truck, they don't reveal many styling details that we haven't seen before such as the headlights that wrap around twin bars that run across the grille. We also spotted a SuperCab version.

In the video above, the Ranger looks in its element as it traverses terrain that includes sand, rocky trails, and ice. The Ranger has been taken for testing in New Zealand, North America, South Africa, Australia, and the Middle East. In some cases, temperatures exceeded 120 degrees Fahrenheit.

"Earning a Built Ford Tough status is not something we take lightly," said Willems. "Every part of the next-generation Ranger was tested to the same standards that we demand of every Ford vehicle."

It's safe to say that the new Ranger will be one of the toughest trucks in its segment when it arrives, although the next-gen Toyota Tacoma might have something to say about that.
