The 6.7 Cummins and 6.7 Powerstroke are both capable engines, but there are key differences between them. Here's everything you need to know.

Cummins Inc. has announced the release of its High Output 6.7-liter Turbo Diesel for Ram Heavy Duty pickup trucks. The new high-output rating produces peak torque of 800 lb ft.

The Cummins 5.9-liter's basic construction makes it more reliable and with fewer reported problems than the 6.7-liter diesel. It also sips less diesel since it has fewer emissions components.
