On the 5th and final day of Diesel Power Challenge 2014, the 10 reader-selected trucks fill up their tanks to test fuel economy before hitching up to the pulling sled in an attempt to haul it as far as possible on a packed down mud track in their final challenge event. Then we wrap-up the weeklong competition by presenting this year's diesel power champion!

Diesel Power Challenge 2014 is a weeklong torture test that features 5 events, 10 trucks, 8,000hp, and nearly 15,000 lb-ft of torque. We push Power Stroke, Cummins, and Duramax-powered trucks well beyond their limits in search of the ultimate diesel.
