Is Cummins really a better diesel engine than Power Stroke?
Comparing the diesel engine models found in Ram trucks versus Ford trucks brings us to the heavy-duty models on the market. When you want power, performance and longevity in the big truck you drive, diesel power is the way to go. The question we want to answer today is whether or not you should consider a Ram with the Cummins diesel engine or a Ford with the Power Stroke model.
What are the diesel engine sizes of the Ford Super Duty and Ram heavy duty trucks?
Kelley Blue Book tells us that Ford Super Duty trucks use a 6.7-liter Power Stroke turbocharged diesel V8 engine mated to a ten-speed automatic transmission. This truck produces 450 horsepower and 1,050 lb-ft of torque. Peak torque occurs at 1,800 rpm.
Ram heavy-duty trucks use a six-cylinder Cummins 6.7-liter turbocharged diesel engine linked to a six-speed automatic transmission. Ram 2500 models produce 370 horsepower and 850 lb-ft of torque, while Ram 3500 diesel trucks deliver 420 horsepower and 1,075 lb-ft of torque. Peak torque occurs at 1,800 rpm in high-output 3500 models according to Kelley Blue Book.
These motors are the same size, which one is better?

The Ford Power Stroke diesel engine offers only one power level, but it has the most power. This power helps the truck accelerate to faster speeds when pulling a heavy load. In addition, the difference in the transmissions favors the Ford. With two extra cylinders and four extra gears, the Ford Power Stroke should offer a smoother ride from standstill to highway speeds.
Which diesel engine comes with a better warranty?
The answer is neither. Power Stroke and Cummins engines both offer a standard warranty covering the engine and other powertrain components for 250,000 miles, according to Pro Source Diesel. This warranty gives you the confidence you need to get the ride off to a good start while enjoying many miles of great driving in either brand of truck.
How much can you tow with these diesel powered trucks?
If you drive the Ford Super Duty with the Power Stroke diesel engine under the hood, you can tow up to 37,000 pounds when properly equipped. If you drive the Ram 2500 with the Cummins engine, towing reaches 20,000 pounds, while the Ram 3500 offers up to 37,100 pounds of towing. The Ram 3500 beats the 100-pound Ford Super Duty if you’re looking for the highest towing rating.
Which diesel engine to choose?
Truck buyers tend to value brand loyalty, which is often passed down from generation to generation. It might sway your purchase decision, but there are some factors to consider once we rule out this factor.
- Higher horsepower and additional ratios of the Power Stroke diesel powertrain provide a smoother ride and acceleration
- The Cummins diesel engine is offered in two heavy-duty truck sizes, giving you two different power levels
To note: A smaller engine, a 3.0-liter EcoDiesel six-cylinder, is available in the Ram 1500, while the Ford F-150 no longer has a diesel engine in the lineup. This smaller diesel engine is not a Cummins model but offers the benefits of diesel power for this half-ton truck.
Overall, the two 6.7-litre diesel powertrains are extremely similar, with almost exactly the same towing capacity, torque and warranty. These two engines might be similar enough to bring you back to brand loyalty to make your final decision when looking for the right diesel truck to drive.
