Diesel Power Challenge 2014 once again returns to the mile-high city of Denver, Colorado to pit 9 of the baddest reader-selected diesel rigs against each other in a head-to-head battle for diesel domination along with last year's returning champion Wesley Beech of Akron, Ohio.

Starting Monday July 21st exclusively on the Motor Trend Channel, host Brian Lohnes takes you through our 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. less
