The contenders for the title of fastest street-driven diesel truck gathered once again in Colorado for the 2015 Diesel Power Challenge in a grueling test of reliability, endurance and performance, and that’s just for the trucks. Once again, Colorado played host to the annual event, with ATS Diesel Performance giving use of its dynamometer to measure the trucks’ prodigious output. This year’s group of competitors hail from all over the U.S. and Canada, with each of the three camps well-represented with high-powered specimens of Power Stroke, Duramax, and Cummins engines.

The competition got a little tougher this year with the additional wrinkle of having the fuel caps locked and sealed, adding fuel economy to the overall judging criteria. The first competition for the contenders is the dyno run, to see which diesel truck makes the most power and torque. Competitors output claims are all over the map, with as much as 1,500 hp and 2,500 claimed lb-ft. But the dyno is the great equalizer, smoking out (so to speak) the pretenders from the contenders. Last year’s winner, Lavon Miller, put down 948.5 horsepower and 2,034 lb-ft to win the dyno competition. We’ll see if those numbers are surpassed this year.

Ram fans are hoping for a repeat of last year’s results, with Lavon Miller’s ’04 Ram 3500 taking the trophy. Going back a few years, Ford trucks won three of the previous four contests, but one of them had a Cummins underhood, giving Cummins-powered rigs a 3-2 margin of victory in the last five contests.
