Comparison of Duramax, Cummins, and Power Stroke Engine Technologies

Enthusiasts and consumers of pickup trucks tend to demonstrate a strong loyalty towards a particular brand, particularly those who opt for brands in the American diesel truck market are General Motors’ Duramax, Ford’s Power Stroke, and Cummins, each known for their high-quality engines.

The EcoDiesel engine, a 3.0-liter V6, has primarily been used in Fiat Chrysler’s (FCA) Ram 2500 and 3500 trucks, but it has also been featured in the Nissan Titan XD. FCA, which owns VM Motori S.p.A., the Italian company engine, has also implemented it in the Jeep Wrangler’s first diesel model in recent years.

The choice between these three diesel pickup truck brands depends on the consumer’s specific needs and preferences. While there are some differences between the engines, it’s not necessarily a matter of one being superior to the others. consider the unique features and capabilities of each brand to determine which one best meets your requirements. Here’s a breakdown of the key differences between the three options.

Which engine is the oldest?

Cummins has a rich history that spans over a century, having been established Its association with Chrysler Corporation’s Ram pickup vehicles began in 1988. In contrast, the GM Duramax range is a relatively newer entity, introduced in 2001. The Ford Power Stroke moniker, on the other hand, has been in use since 1994. When pitting Duramax engines against Cummins and Power Stroke engines, the latter’s seniority is undeniable.

Which engine generates the most torque?

The main purpose of large, heavy-duty trucks is for towing. Towing requires torque, which diesel engines can provide more of compared to gasoline engines due to their longer and more consistent combustion process, enabling longer connecting rods.

The 2021 Ford F-Series Super Duty, when equipped with the available 7.3-liter turbocharged V8 engine producing 475 horsepower, boasts a torque capacity of 1050 lb.-ft., thanks in part to its advanced fuel-injection technology that operates at an impressive 36,000 pounds per square inch. This significant upgrade results in more torque than the 2019 6.7-liter Power Stroke turbodiesel engine, which produces 935 lb.-ft. of torque.

Simultaneously, the 2021 Chevrolet Silverado HD and its equivalent, the GMC Sierra HD, boast a Duramax diesel engine that churns out a staggering 910 pounds per foot of rotational force. In contrast, the 2021 GMC Yukon and Yukon XL rely on a 3.0-liter turbodiesel engine, which generates 277 horsepower and 460 pounds per foot of rotational force, significantly less than its heavy-duty counterparts.

In contrast, the Ram Heavy Duty’s powerful 6.7-liter Cummins turbo diesel engine produces an impressive 930 pound-feet of torque. Meanwhile, the larger and more abundant Ram 3500 Laramie takes it to the next level, churning out a staggering 1,000 pound-feet of torque.

With the exception of the smaller GMC, domestic manufacturers offer similar torque capabilities. However, factors such as weight and additional equipment loads can affect overall performance.

What about power?

When it comes to towing, torque takes precedence, but horsepower remains a crucial factor. A higher horsepower rating enables a vehicle to achieve quicker acceleration, even when unladen. Having extra horsepower on tap can be beneficial when you need to rapidly accelerate while hauling a heavy load. The Power Stroke and Duramax engines are closely matched in terms of horsepower, with the former producing 450 and the latter 445. Ram trucks’ Cummins engines, meanwhile, deliver 400 horsepower. While the Power Stroke engine edges out the competition in this category, its lead is slim.

Towing Capability

The amount of weight a truck can carry is influenced by both torque and horsepower, but other factors also play a role. the truck and the power of its engine are significant considerations. It’s worth noting that in the United States, a’s license is required for towing loads exceeding 26,000 pounds.

The Power Stroke outperforms again, boasting a towing capacity of 34,000 pounds compared to the Ram’s 31,210 pounds. While both the Ram Cummins and Ford Power Stroke can handle heavier loads, the Duramax lags behind with a towing capability of 23,300 pounds. Despite these differences, for everyday truck owners without a commercial license, any of these would definitely be suitable for their needs.

Is Fuel Economy Important?

Ultimately, heavy-duty diesel trucks are built for productivity rather than fuel efficiency. Due to their size, the EPA doesn’t evaluate their fuel economy like they do for smaller trucks, making it difficult to determine. Nevertheless, diesel engines are generally more effective than gasoline engines, potentially resulting in a greater driving distance in typical conditions.

Both General Motors and Ford, two of the top three manufacturers of diesel engines, have expanded their engine offerings to smaller vehicles. Chevrolet Colorado and GMC Canyon from General Motors are equipped with a 2.8-liter four-cylinder diesel engine that achieves 30 mpg on the highway. On the other hand, Ford’s F-150 is powered by a 3.0-liter V6 Power Stroke diesel engine, which gets 26 mpg on the highway. The choice between the two ultimately depends on the buyer’s priorities.

Diesel Trucks to Consider in 2021

When it comes to the latest generation of diesel vehicles, the market is ripe for the taking. According to U.S. News & World Report study, some of the top factors include both light- and heavy-duty pickups, such as:

Duramax Chevrolet Colorado A 2.8-liter turbo diesel 4-cylinder Chevy Duramax engine with 181 horsepower and 369 pound-feet of torque is available.

Duramax GMC Canyon It has a towing capacity of 7,700 pounds and a torque output of 369 ft.-lb. From its 2.8-liter 4-cylinder engine.

EcoDiesel Ram 1500 The Ram 1500 for 2021 can tow up to 12,560 pounds and has 480 pound-feet of torque. A 3.0-liter EcoDiesel V6 engine powers the Ram.

2500/3500 Chevrolet Silverado This massive Chevy truck can tow 36,000 pounds and is powered by a 6.6l Duramax turbo V8 with 445 horsepower and 910 ft.-lb. Of torque.

The 6.7l Cummins engine produces an outstanding 420 horsepower and 1,075 lb.-ft. 2500/3500 Ram. of best-in-class torque. The American love affair with diesel vehicles is on the mend, partly owing to the availability of diesel engines in smaller and lighter-duty trucks. These cars not only have the torque required for towing and appropriate payload capabilities, but they are also associated with remarkable fuel efficiency rankings, exhaust-cleaning systems for reduced emissions, and drivetrains that make them cleaner to drive than ever before.
