2026 Ram 2500 Engine Choices
If you’re searching for the most complete breakdown of the 2026 Ram 2500, including every engine choice, trim level, towing and payload rating, bed size, and tech feature, you’ve found it.
🔧 Engine Lineup & Performance
The 2026 Ram 2500 offers two powerhouse engines that define heavy-duty versatility — the proven 6.4-liter HEMI V8 gas and the legendary 6.7-liter Cummins Turbo Diesel I6. Both are mated to refined 8-speed automatic transmissions, tuned for strength and smoothness.
⚙️ 6.4-L HEMI V8 Gasoline
- Output: 405 horsepower / 429 lb-ft of torque
- Transmission: 8-speed automatic
- Towing Capacity: Up to ~17,750 lb (when properly equipped)
- Payload: Up to ~4,420 lb
This V8 provides immediate throttle response, linear torque delivery, and a traditional gasoline driving feel that many fleet buyers and recreational haulers prefer.
Its lower upfront cost and easier maintenance compared to diesel make it attractive for general contractors and light-duty towing applications.
⚙️ 6.7-L Cummins Turbo Diesel High Output
- Output: 430 horsepower / 1,075 lb-ft of torque
- Transmission: 8-speed TorqueFlite HD automatic
- Towing Capacity: Up to 20,000 lb (2500 configuration)
- Payload: ~2,740 lb in select trims
The Cummins diesel remains a benchmark for torque and endurance. It’s ideal for fifth-wheel trailers, horse haulers, and commercial loads.
When paired with the Ram 2500’s heavy-duty chassis, this engine delivers confident highway pulling, strong compression braking, and excellent longevity.
The available 6.7L Cummins turbo-diesel remains one of the most trusted powerplants in the segment, praised for its durability and torque delivery. Car and Driver
🚛 Towing, Payload & Tongue Weight
Official towing ratings are published by Ram for each configuration, confirming diesel models can reach up to 20,000 pounds when properly equipped. Ram Trucks Official Site
Towing is where the Ram 2500 defines its reputation.
- Gas model: Up to 17,750 lb towing capacity
- Diesel model: Up to 20,000 lb towing capacity
- Payload range: ~2,700 – 4,400 lb depending on engine and trim
⚖️ Understanding Tongue Weight
A safe and stable towing setup requires maintaining 10–15 percent of your trailer’s total weight as tongue weight.
For example:
- 15,000-lb trailer → ~1,500–2,250 lb tongue weight.
That load counts toward your truck’s payload capacity.
⛽ Fuel Economy
Because the Ram 2500 is a heavy-duty truck with a GVWR over 8,500 lb, the EPA does not rate its fuel economy. However, owners and fleet data suggest:
- Gas 6.4 L HEMI: ~14–16 MPG combined (unloaded)
- Diesel 6.7 L Cummins: ~17–19 MPG combined (unloaded)
🛋️ Interior Comfort & Cabin Design
The 2026 Ram 2500 continues to lead the segment for interior refinement. Even base models offer excellent fit and finish, while higher trims introduce luxury-grade materials and technology.
Higher trims like the Limited and Longhorn deliver premium leather, open-pore wood, and real metal accents. MotorTrend
