Just when you thought the Diesel Power Challenge could not get any better, we had the biggest batch of competitors in the history of the event this year. One dozen ultramodified diesel trucks survived the journey to Salt Lake City, Utah. They hit the dragstrip, towed a 12,000-pound trailer, braved city streets during the fuel economy test, and tugged a sled in the middle of a howling rainstorm. You can read all about our event coverage in next month's issue of Diesel Power that hits newsstands on August 5th. For now, check out these competitors and see if you can guess who has what it takes to win the 2008 Diesel Power Challenge.
