Diesel Power Challenge

Nine trucks are strapped to the dyno to find out which one is the most powerful.

The trucks go head-to-head in a bracket-style drag race before a Rocky Mountain fuel economy test.

Each truck must drag a professional-level pulling sled 300 feet across a packed mud pit!

The Diesel Power Challenge 2014 kicks off with trucks strapped down for the dyno competition.

The drivers hit a CDL-style obstacle course where each truck pulls a 10,000-pound trailer behind it.

The trucks tow 10,000-pound trailers through a single 1/8-mile dragstrip pass.
