In this video, I rank the 2026 heavy-duty diesel powertrains from best to worst, taking a close look at Cummins, Power Stroke, and Duramax. This isn’t just an engine comparison—I’m ranking the entire powertrain, because in the HD truck world the transmission plays a massive role in how these trucks perform, tow, and hold up long term.

I break down what Ram has done with the updated Cummins and their move to the ZF Powerline 8-speed, why I think that transmission is a huge step forward, and how it influenced my rankings. I also talk about Ford’s Power Stroke paired with the 10R140 and GM’s Duramax with the 10L1000, including what I like, what I don’t, and where I think each setup could be better.

These are my real-world impressions based on engineering, reliability history, towing performance, and overall drivability—not just spec sheets.

If you’re shopping for a heavy-duty truck, or you’re just a diesel nerd like me who loves digging into the details, this breakdown should help you understand the real differences between today’s HD diesel trucks.
