2026 Ram 2500 Engine Options & Specs
While the light-duty Ram 1500 has moved to the twin-turbo Hurricane inline-six, the 2026 Ram 2500 stays true to its roots.
At Champion CDJR Gulfport, we can confirm: The 6.4L HEMI® V8 is standard, and the 6.7L Cummins® Turbo Diesel is available.
For our customers towing excavators to job sites or fifth-wheels to the campgrounds, this is the news you wanted to hear.
Here is the definitive breakdown of the two engine heavyweights.
Option 1: The Standard 6.4L HEMI® V8
This is the standard engine for a reason. It is a proven, naturally aspirated workhorse that uses Variable Valve Timing (VVT) and Fuel Saver Technology (cylinder deactivation) to balance massive power with reasonable efficiency.
Best For: Daily driving, hauling payloads (gravel, lumber), and towing lighter campers (under 12,000 lbs).
The Transmission Update: For 2026, the Hemi is paired with the refined ZF 8-speed automatic. This transmission shifts smoother and hunts for gears less than the older 6-speed, helping you stay in the power band while towing up bridges or on-ramps.
Option 2: The 6.7L Cummins® Turbo Diesel I6
This is the legend. The inline-six architecture provides naturally balanced torque that V8 diesels can't match. It doesn't just pull; it accelerates under load.
Best For: Towing heavy fifth-wheels, livestock trailers, or construction equipment (15,000+ lbs).
The Difference: The Cummins produces nearly double the torque of the Hemi. When you hit a steep grade while towing, the Hemi needs to downshift and rev high; the Cummins just builds boost and maintains speed without drama.
Spec Showdown: Gas vs. Diesel
Why Is the Gas Payload Higher?
This is a common point of confusion. The Hemi V8 payload is higher (4,010 lbs vs. 3,160 lbs) because the engine itself is much lighter.
The Cummins diesel engine block is massive cast iron. That extra engine weight eats into your Gross Vehicle Weight Rating (GVWR).
- Champion Tip: If you plan to put a heavy slide-in camper in the bed, the Hemi V8 is often the safer legal choice due to its higher payload capacity.
Which Engine Should You Choose?
- Choose the Hemi V8 If: You want a lower purchase price, you drive short distances (diesels hate short trips), or you need maximum payload for a truck bed camper.
- Choose the Cummins Diesel If: You tow over 12,000 lbs regularly, you drive high highway miles (better range), or you want the resale value retention that only a diesel offers.
