Meet the players, and watch as they square off in the first competitive segment of Diesel Power Challenge 2018 Presented by XDP. The chassis dyno at ATS Diesel Performance is the place where it all went down and where it’s “all about the numbers,” as peak horsepower and torque numbers are added together to determine a truck’s rear-wheel-performance total. Starting October 8, 2018 exclusively on the Motor Trend YouTube Channel, host Alan Reinhart takes you through our weeklong torture test that features 6 competitive segments, 9 trucks, and 20,522.3 combined horsepower and torque at the rear wheels. We push Cummins, Duramax, and Power Stroke-powered trucks well beyond their limits in this search for the ultimate street-legal diesel truck and driver.
