Cummins standard output vs high output has a short answer for 2027: there is no choice to make on a new Ram 2500 or 3500 pickup, because Stellantis Canada lists one diesel for both, the 6.7 litre Cummins High Output turbo diesel at 430 horsepower and 1,075 lb ft of torque. The standard output Cummins belongs to earlier model years, so the comparison matters most when you shop a used heavy duty. To see what is listed now, browse new Ram 2500 inventory at Dunn Ram Trucks, or look through our used vehicle inventory if an older Cummins is on your list.

Our 2027 figures come from Stellantis Canada's 2027 Ram Heavy Duty Canada press kit, dated July 27, 2026, and from Ram Canada's 2027 Ram 2500 and Ram 3500 pages. The earlier figures come from Stellantis Canada's 2024 Ram Heavy Duty Canada press kit, dated September 7, 2023, and its January 7, 2025 release on the 2025 Ram 2500 and 3500. We read all of them on November 1, 2026.
Key Takeaways
- The verdict: a 2027 Ram 2500 or 3500 pickup has one Cummins, the High Output, rated at 430 horsepower and 1,075 lb ft in Stellantis Canada's July 27, 2026 press kit.
- The split was real in 2024. The 2024 press kit lists the standard output at 370 horsepower and 850 lb ft for the Ram 2500 and 3500, and the High Output at 420 horsepower and 1,075 lb ft for the Ram 3500.
- 2025 changed it. Stellantis Canada's January 7, 2025 release says the 2025 Ram 2500 now offers the Cummins High Output, available in all Heavy Duty variants.
- The other 2027 engine is gas. It is the 6.4 litre HEMI V8, and in Canada the 2027 Ram 2500 Power Wagon is gas only.
- On a used truck, read the original window sticker. For a 2024 or earlier truck, the model year alone does not always tell you which Cummins it has: a 2024 Ram 3500 diesel could have either output.
Cummins Standard Output vs High Output, Year by Year
Here is how the two outputs line up across the years Stellantis Canada documents.
| Model Year | What Stellantis Canada Lists |
|---|---|
| 2024 | Standard output: 370 hp and 850 lb ft (Ram 2500 and 3500). High Output: 420 hp and 1,075 lb ft (Ram 3500). |
| 2025 | High Output: 430 hp and 1,075 lb ft, available in all Heavy Duty variants, Ram 2500 included. |
| 2027 | High Output: 430 hp and 1,075 lb ft, with a TorqueFlite HD eight speed automatic. No standard output is listed. |
The 2024 row comes from the 2024 press kit, the 2025 row from the January 7, 2025 release, and the 2027 row from the July 27, 2026 press kit. For a 2023 or earlier truck, look up that model year's own Canadian release or read the truck's original window sticker, because the split by model and output changed over the years. This post covers the 2500 and 3500 pickups; a Ram Chassis Cab carries its own Cummins rating, so read its window sticker.
The 2027 Cummins High Output
Power and torque. Stellantis Canada's July 27, 2026 press kit rates the 6.7 litre Cummins HO turbo diesel at 430 horsepower and 1,075 lb ft, paired to a TorqueFlite HD eight speed automatic, and lists it under both the Ram 2500 and the Ram 3500.
How Ram Canada describes it. Ram Canada's 2027 Ram 2500 page calls 1,075 lb ft best in class available base diesel torque, with the class based on 250/2500 pickups and the latest available competitive information. Ram Canada's 2027 Ram 3500 page describes the same figure as 1,075 lb ft of available base diesel torque. Both pages describe the 6.7L diesel as available.
Canada's longest lasting line. Ram Canada's 2027 Ram 2500 and 3500 pages call Ram's heavy duty diesels Canada's longest lasting heavy duty diesel pickups, based on S&P Global Mobility Canadian vehicles in operation and new registration data as of July 1, 2025, for model years 2002 to 2026.
Warranty. A 2027 Ram with the Cummins carries Ram Canada's separate 5 year or 160,000 km Cummins engine warranty, whichever comes first, on top of Ram Canada's standard 2027 warranty terms. Ram Canada's 2027 pages list the basic warranty at 3 years or 60,000 km.
If you are shopping a new one, new Ram 3500 inventory sits beside the 2500. The figures above belong to the 2027 model year; a 2026 truck has its own window sticker, and that sticker names its engine.
The Standard Output Cummins
Where it sat. Stellantis Canada's 2024 press kit lists the 6.7 litre Cummins standard output turbo diesel at 370 horsepower and 850 lb ft for the Ram 2500 and 3500. The High Output in that kit, at 420 horsepower and 1,075 lb ft, is listed for the Ram 3500 only. So a 2024 Ram 2500 diesel is a standard output truck.
What changed after it. Stellantis Canada's January 7, 2025 release says the 2025 Ram 2500 now offers the Cummins High Output, and in the same sentence credits the 2025 Ram 2500 with 0 to 96 km/h in 6.9 seconds against 8.0 seconds on the 2024 model year.
What it still means for you. A standard output truck is a used truck. Its towing and payload ratings belong to its own model year and configuration, so ask our team to confirm them for the exact truck, not against a 2027 figure.
Fuel Consumption: No Official Figure for Either
Natural Resources Canada's 2026 Fuel Consumption Guide says manufacturers are not required to submit fuel consumption data for pickup trucks with a gross vehicle weight rating of more than 3,856 kg (8,500 lb) and an interior bed length of 183 cm (72 in) or more. If the GVWR on a truck's door label is above that and its box is that long, there is no Natural Resources Canada rating to set one Cummins against the other, so a precise figure quoted for either output is not an official rating. Keep a fuel log over a season with your own trailer and roads instead.
Who Should Buy Which
Buy a 2027 Ram with the Cummins High Output if you pull a gooseneck or fifth wheel out of Portage la Prairie: a grain or stock trailer down a grid road to the Trans-Canada Highway, a camper to Lake Manitoba, or equipment west to Brandon into a headwind. The 1,075 lb ft is what does that work, and for 2027 it is the only Cummins Stellantis Canada lists, so the decision is diesel or gas, then 2500 or 3500. Ask our team to confirm the towing rating of the exact build against your trailer before you buy.
Look at a used standard output truck if your trailer sits well inside that truck's own rating and you want a Cummins with kilometres on it. A 2024 Ram 2500 diesel is a standard output truck at 370 horsepower and 850 lb ft by the 2024 press kit, so read the door label and the original window sticker before you hook up.
Look at the 6.4 litre HEMI V8 if your heavy duty mostly commutes to Winnipeg, plows the yard and pulls lighter loads. It is the other engine on the 2027 Ram 2500 and 3500, and the 2027 Ram 2500 Power Wagon in Canada comes with it only.
A Minus 30 Start With Either Cummins
A minus 30 morning is hard on any diesel. Stellantis Canada's January 7, 2025 release says that, to help customers in extremely cold environments, Ram Heavy Duty trucks equipped with the Cummins High Output turbo diesel use glow plugs. Our wait to start light explainer, which covers what changes by model year, walks through the preheat on older and newer trucks.
If your truck has a block heater, plug it in the way its manufacturer directs before a cold start; if it does not, our service department installs block heaters, and you can book a block heater installation with our service team. Fuel matters as much as the engine on that first deep cold morning, and our post on diesel fuel gelling in Manitoba covers winter blends and additives.
FAQs
Is there a standard output Cummins on the 2027 Ram 2500?
No. Stellantis Canada's July 27, 2026 press kit lists one diesel for the 2027 Ram 2500 and 3500, the 6.7 litre Cummins High Output turbo diesel at 430 horsepower and 1,075 lb ft. The standard output, rated at 370 horsepower and 850 lb ft in the 2024 press kit, belongs to earlier trucks.
How much power does the 2027 Cummins High Output make?
430 horsepower and 1,075 lb ft of torque, by Stellantis Canada's July 27, 2026 press kit, paired to a TorqueFlite HD eight speed automatic. Ram Canada's 2027 Ram 2500 page calls the 1,075 lb ft best in class available base diesel torque, with the class based on 250/2500 pickups.
Did a Ram 2500 ever come with the High Output Cummins?
Yes, from the 2025 model year. Stellantis Canada's January 7, 2025 release says the 2025 Ram 2500 now offers the Cummins High Output. The 2024 press kit lists the High Output for the Ram 3500 and the standard output for the 2500 and 3500.
Can I get a 2027 Ram Power Wagon with the Cummins?
No. The 2027 Ram 2500 Power Wagon in Canada is gas only, with the 6.4 litre HEMI V8, and Stellantis Canada's July 27, 2026 press kit describes the Power Wagon with HEMI power.
Where can I see a new 2027 Ram 2500 or 3500 near Portage la Prairie or Winnipeg?
On our new Ram 2500 inventory page and our new Ram 3500 inventory page, which show the trucks listed today at Dunn Ram Trucks in Portage la Prairie; each listing's window sticker names its engine. We deliver anywhere in Manitoba with road access; ask our team about the details.
The Bottom Line
For 2027 the choice between Cummins outputs is made for you: the Ram 2500 and 3500 pickups carry the High Output at 430 horsepower and 1,075 lb ft, and your real decision is diesel or gas, then 2500 or 3500. The standard output question lives on the used side, where a 2024 or earlier truck's original window sticker settles which Cummins it has.
