Video Description

Which one do you think is the best or worst? Some engines made history by hauling thousands of tons across America with power and reliability. Others became cautionary tales, remembered for breakdowns, blown head gaskets, and leaking oil. In this video, we’re heading into the world of vintage American diesel engines — ranking 20 of the most notable ones from worst to best based on their real-world performance in long-haul trucking. This ranking is based on key factors that matter most to truckers and fleet owners alike: horsepower, torque, fuel economy, uptime, serviceability, and how these engines actually performed under the brutal demands of the open road. Some engines earned their spot on this list through sheer durability and efficiency. Others, not so much. Whether you’re a diesel enthusiast, a former driver who ran these engines yourself, or just someone fascinated by the evolution of American trucking, this video offers a comprehensive and opinionated look at the mechanical hearts that powered the nation's freight industry. As we count down from number 20 to number 1, you’ll see how engineering, innovation, and sometimes failure shaped the legacy of each engine on this list. Some were designed for military or industrial use but ended up in trucks. Some were ahead of their time. Others were quickly forgotten for good reason. If you’re passionate about diesel history, truck culture, or American industry, make sure to watch until the end — the engine that takes the top spot might just surprise you.
