For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.

What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.

You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

      Wow, 10.8 @ 129 for a truck with a lift kit. I honestly didn't they could go that fast.

        These newer diesel trucks are no joke! They can be faster in a drag race with only a programmer then alot of sports cars on the road!

          Sorry I thought you were referring to the trailer pull. The drag race was indeed quarter mile.

          129mph in the 1/8th would've been plenty to embarass sports cars, lol. Still plenty fast enough to embarass 98% of the street driven cars out there.

          That was an 1/8 mile drag race so they are not faster than a lot of sports cars.

      The truck that pulled 2nd farthest on the dirt got the highest average mpg. And in the rockies, 22+ isn't bad. That's probably equivalent to much high mpg at sea level. Really goes to show what these engines are capable of, and I hope manufacturers continue to improve the designs for reliability and capability.

      euro emission engineers will be shocked to death if they saw the drag race clip

        And yet many euro diesels can't meet US emission requirements... you have your wires crossed.

          Weird that clean, economical euro diesel cars have a hard time meeting US emission requirements yet HD trucks capable of belching enough black smoke to block out the sun seem to get by just fine.

          the trucks are not held to the same requirements.....
