Diesel Power Challenge 2013 returns to the mile-high city of Denver, Colorado to pit the 9 of the baddest reader-selected diesel rigs against each other in a head-to-head battle for diesel domination.

Starting Monday August 5th exclusively on the Motor Trend Channel, host Brian Lohnes takes you through our weeklong torture test that features 7 events, 9 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
