On Day 2 of Diesel Power Challenge 2014, the 10 reader-selected truck contenders kick off with an event designed to assess each driver's skill. The spotlight shifts from the truck's go-fast prowess to the driver's ability to navigate a CDL-style obstacle while maneuvering with a 10,000-pound tractor-carrying trailer in tow. The driver to complete the course in the shortest time will inch closer to this year's challenge title. 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.
