2025
Given that 70% of RAM heavy-duty customers opt for the diesel engine, it’s no surprise that a new diesel engine joined the 2025 RAM Heavy-Duty lineup. This model year, those Ankeny drivers looking to upgrade their old diesel workhorses for something new can opt for the 2025 RAM 2500, which can now be had with the time-tested gas-operated 6.4L HEMI® V8 or the new 6.7L Cummins High-Output Turbo Diesel engine.
In this performance overview, DeYarman CDJR Ames presents details on the 2025 RAM 2500 Cummins specs to show you how much this engine improves the performance of this heavy-duty pickup compared to the steadfast HEMI® V8. From the 2025 RAM 2500 horsepower output to the RAM 2500 0-60 times and more, we’ll compare the 2025 RAM 2500 diesel specs with its well-known gas-powered mainstay so you can decide which engine is most appropriate for your Boon needs.
2025 RAM 2500 Gas Engine Specs: The 6.4L HEMI® V8
Those who have driven a RAM Heavy-Duty pickup for a while will undoubtedly reminisce fondly about the 6.4L HEMI® V8 engine. Solidly constructed using a mixture of cast iron, aluminum, and forged steel, this gasoline-powered standby has proved its worth through more than a decade of rigorous use. Check out its specifications below:
- Horsepower: 405 hp @ 5,600 rpm
- Torque: 429 lb-ft of torque @ 4,000 rpm
- Maximum Engine Speed: 5,800 rpm
- Compression Ratio: 10.0:1
- Fuel Requirement: Unleaded, regular, 87 octane
- Oil Capacity: 7.0 quarts (6.6 liters)
- Coolant Capacity: 16.6 quarts (15.75 liters)
- Maximum Trailer Weight Rating: 17,750 pounds
2025 RAM 2500 Diesel Specs: The 6.7L Cummins High-Output Turbo Diesel I6
Boasting a best-in-class standard 1,075 lb-ft of torque straight out of the gate, the 2025 RAM 2500 Cummins specs are impressive indeed. Let’s see how the specs of this powerful inline 6 engine compare to the 6.4L HEMI® V8 in terms of the 2025 RAM 2500 horsepower specs and more:
- Horsepower: 430 hp @ 2,800 rpm
- Torque: 1,075 lb-ft of torque @ 1,800 rpm
- Maximum Engine Speed: 3,200 rpm (maximum high-idle engine speed)
- Compression Ratio: 16.2:1
- Fuel Requirement: Ultra-low sulfur diesel
- Oil Capacity: 12.0 quarts (11.3 liters) w/ filter
- Coolant Capacity: 23.8 quarts (22.5 liters)
- Maximum Trailer Weight Rating: 20,000 pounds
While the new 6.7L Cummins engine only improves on the 2025 RAM 2500 horsepower specs of the 6.4L HEMI® by 25 ponies or so, keep in mind that the former is a diesel-powered engine and therefore achieves this with far lower engine speeds (5,600 rpm for the HEMI® versus 2,800 rpm for the Cummins). This makes the 6.7L Cummins a far more powerful engine than the HEMI® V8. While the latter certainly still has a place, for high-intensity projects where tremendous amounts of torque and power are required, it appears that the Cummins engine has a leg-up on the HEMI®.
In addition, the latest Cummins diesel engine also improves the RAM 2500 0-60 times, pushing it down to 6.9 seconds from 8.0 seconds in the 2024 model year So, not only does the 6.7L Cummins provide a legendary amount of towing power with the RAM 2500, it also quickens the pickup, potentially increasing its maneuverability on crowded %target_city_3%% roads.

2024 RAM 2500 Engine
The standard RAM 2500 engine powering the lineup is the famous 6.4L HEMI® V-8. While powerful and reliable, those seeking even more power can opt for the 6.7L Cummins Turbo Diesel I-6. Optional for all trims other than the Power Wagon®, losing 40 hp by switching from the HEMI® seems trivial when you gain over 400 lb-ft of torque with the Cummins!

- Paired with automatic eight-speed automatic transmission
- Maximum towing capacity: 17,420 pounds

Loading and unloading is a different matter entirely, but with a payload capacity of 3,150 pounds and a spacious interior, we’re sure you’ll have enough room to take a helpful crew along!
2024 RAM 2500 Fuel Tank Size
