In the foreground, one of the latest Bigfoot team trucks, Bessie, comes to a landing with Larry Swim behind the wheel. The XDP diesel takes off in the background. After Lima, Swim and Bessie were running fourth for points in the 2012 standings. The XDP diesel monster truck is the only diesel truck competing so far. It made its debut earlier in 2012. It’s running a 6.7L Cummins inline-six with around 1,200 hp versus the V-8s running 1,500 to 1,800 hp from 540 to 565 ci. In acceleration, the diesel just doesn’t have the snap of a gasser. Gas versus diesel is a new concept in the monster truck game, so we’ll see how it evolves.
