In this clip from my full 2025 HD gas engine rankings, I break down where the 6.4L HEMI stacks up — and why I placed it at #3 out of 4 this year. The HEMI is a very solid engine with great sound, good throttle response, and a proven track record, but when you compare it directly against the other HD gas engines for towing performance, gearing, stability, and real-world efficiency, it just doesn’t edge out the top two.

Today we’re taking a full deep dive into the 6.4L HEMI in the Ram 2500 — one of the most underrated gas HD truck engines on the market.
