What are the engine options of the 2027 Ram 2500?

The 2027 Ram 2500 keeps its engine menu simple and serious: a proven 6.4L HEMI V8 or the 6.7L Cummins High Output turbo diesel. Each pairs with a TorqueFlite eight-speed automatic, and each has a clear personality, so the choice comes down to how you work.

Below, our team at Glendale CDJR in St. Louis, MO lays out both engines, their ratings, and how to decide between them, including this year's headline that even the Power Wagon can now be ordered with the Cummins.

2027 Ram 2500 6.4L HEMI V8
V

The standard 6.4L HEMI V8 in the 2027 Ram 2500 delivers 405 horsepower and 429 lb-ft of torque through a TorqueFlite eight-speed automatic. It is a responsive, gas-fueled workhorse that tows up to 17,740 pounds when properly equipped, and for 2027 HEMI trucks wear a new V8 fender badge.

The HEMI is also the key to this year's new Payload Upgrade Package, which lifts maximum payload to 4,580 pounds on gas trucks. For crews that haul more weight in the bed than behind the bumper, the V8 with the package is a smart, lower-cost build.

  • 405 horsepower and 429 lb-ft of torque
  • TorqueFlite eight-speed automatic
  • Up to 17,740 pounds of towing when properly equipped
  • Supports the new 4,580-pound Payload Upgrade Package
  • New V8 fender badge for 2027

2027 Ram 2500 6.7L Cummins Turbo Diesel
V

The available 6.7L Cummins High Output turbo diesel gives the 2027 Ram 2500 its headline numbers: 430 horsepower and 1,075 lb-ft of torque, best-in-class standard diesel torque, driving a heavy-duty TorqueFlite HD eight-speed. That torque arrives low in the rev range, exactly where heavy trailers need it.

Properly equipped, Cummins-powered 2500s tow up to 20,000 pounds. New for 2027, the off-road Power Wagon offers the Cummins for the first time, along with its first available fifth-wheel/gooseneck prep, a combination West County ranchers and rural Missouri buyers have been requesting for years.

  • 430 horsepower and 1,075 lb-ft of torque
  • Best-in-class standard diesel torque
  • TorqueFlite HD eight-speed automatic
  • Up to 20,000 pounds of towing when properly equipped
  • Now available on the Power Wagon for 2027

Choosing the Right 2027 Ram 2500 Engine

Pick the HEMI if your work leans on payload, shorter trips, and a lower purchase price; it carries the biggest bed loads thanks to the new payload package and costs less up front. Pick the Cummins if your trailer is heavy or your miles are long; its 1,075 lb-ft and 20,000-pound rating shrug off fifth-wheel campers and equipment trailers.

Both engines run through the same basic driveline family with 4x2 or 4x4, so cab, box, and axle choices finish the build. Our team at Glendale CDJR can price both versions of the same truck so you can compare them side by side.

  • HEMI V8: best for payload-first work and value
  • Cummins diesel: best for heavy trailers and long miles
  • Both use TorqueFlite eight-speed automatics
  • 4x2 and 4x4 available with either engine
  • Every trim offers a clear gas or diesel path
