Semi-trucks are typically associated with hauling heavy loads on highways, not with high speed and rapid acceleration. However, in the world of drag racing, these massive machines defy expectations. With tuned engines, they emit clouds of black smoke as they tear down the track.

In a 40-minute video dedicated to semi-truck drag racing, viewers are treated to a variety of thrilling runs. While it’s best to scrub through the entire video to see the wide array of trucks on display, there are a few highlights to look out for.

One exciting moment occurs around eight minutes and 33 seconds when semi-trucks pulling trailers engage in a drag race. These big rigs haul three bundles of logs weighing multiple tons. The twist in this run is that the truck on the left generates so much torque that the hood visibly twists.

Another notable run takes place at 18:11, where a semi-truck on the left flexes and twists as it leaves the starting line. Both competitors release a substantial amount of black smoke as they cover the distance.

If you’re interested in witnessing particularly fast runs, skip to 21:33 or 35:36 in the video. While the exact quarter-mile times of these trucks are not provided, they appear to be much quicker than the other runs in the clip.

In addition to the intense races, the sound these trucks produce is worth mentioning. Equipped with big turbos to boost their performance, they emit a whistling sound that resembles a jet flying down the track.

One of the most eye-catching rigs appears at 27:41. This truck features a large turbo inlet protruding from its hood and an orange flame paint scheme. With the exhaust positioned in front of the passenger side of the windshield, it is impossible to miss. This truck makes multiple appearances throughout the video.
