It's edition IV, the battle of Bowling Green. Ford vs Dodge vs Chevy and the clash of the diesel truck titans. You'll see chasis dynomometer, 1/4 mile heads up drag racing, 1/8 mile drage with 10,000 lb trailer, fuel consumption road loop and sled pull. It's the Diesel Power Challenge presented by Diesel Power magazine. This edition goes down as the most action packed event ever with 14 trucks competeing in 5 unforgiving tests of performance.
