What are the engine options of the 2027 Ram 3500?

Two engines carry the 2027 Ram 3500: the 6.4L HEMI V8 for gas simplicity and the 6.7L Cummins High Output turbo diesel for maximum pull. The right one depends on what is on the hitch, and the difference is bigger in the one-ton class than anywhere else.

Below, our team at Glendale CDJR in St. Louis, MO lays out both 2027 Ram 3500 engines and offers a straightforward way to choose between them.

Full 3500 Review
2027 Ram 3500 6.4L HEMI V8
V

The standard 6.4L HEMI V8 in the 2027 Ram 3500 makes 405 horsepower and 429 lb-ft of torque through a TorqueFlite eight-speed automatic. It is the payload champion of the lineup, supporting the truck's maximum 7,580-pound rating, and it tows up to 18,140 pounds when properly equipped.

Gas power keeps the purchase price and maintenance simpler, and for 2027 the HEMI wears its own V8 fender badge. For crews hauling weight in the bed more than behind the truck, it is the value pick.

  • 405 horsepower and 429 lb-ft of torque
  • Supports the maximum 7,580-pound payload
  • Up to 18,140 pounds of towing when properly equipped
  • TorqueFlite eight-speed automatic
  • New V8 fender badge for 2027

2027 Ram 3500 6.7L Cummins High Output Turbo Diesel
V

The available 6.7L Cummins High Output turbo diesel is why the 2027 Ram 3500 leads conversations about maximum towing: 430 horsepower and a best-in-class 1,075 lb-ft of torque, paired with the TorqueFlite HD eight-speed. Properly equipped dually configurations tow up to 37,020 pounds, this year's new high.

The Cummins delivers its torque low and steady, exactly what a 20,000-pound fifth-wheel needs on a grade, and it has anchored Ram heavy-duty credibility for decades. If the trailer is measured in tens of thousands of pounds, this is the engine.

  • 430 horsepower and 1,075 lb-ft of torque
  • Best-in-class standard diesel torque
  • Up to 37,020 pounds of towing when properly equipped
  • TorqueFlite HD eight-speed automatic
  • Decades of Cummins heavy-duty pedigree

Choosing the Right 2027 Ram 3500 Engine

Choose the HEMI if payload rules your work, if trips are shorter, or if up-front cost matters most; it carries the heaviest bed loads and keeps things simple. Choose the Cummins if you tow above roughly the HEMI's 18,140-pound ceiling, cover long miles, or want the strongest resale story in the segment.

Both engines offer 4x2 or 4x4 and single or dual rear wheels, so the driveline follows the engine decision naturally. Our team at Glendale CDJR will run the numbers on your actual trailer before you commit.

  • HEMI V8: maximum payload and lower cost of entry
  • Cummins HO: maximum towing and long-haul strength
  • Both pair with TorqueFlite eight-speed automatics
  • SRW or DRW with either engine
  • 4x2 and 4x4 drivelines available
