The engine

Cummins

6.7L Turbodiesel I6

A tireless, low-revving diesel straight-six that delivers a wall of torque from just off idle, prized for effortless heavy towing and a deep, signature clatter under load.

Designed and built by Cummins in Columbus, Indiana, descended from the legendary 5.9-liter Cummins that turned the Dodge Ram into a diesel icon starting in 1989.

The High-Output version's torque has climbed past 1,000 lb-ft, among the highest figures ever offered in a production pickup.
The lineage traces directly from the original 5.9-liter, 160-horsepower engine through decades of continuous evolution to today's 6.7.
Its inline-six layout is inherently well-balanced, a key reason it has endured where some rivals moved to V8 diesels.
