The Duramax 6.6-liter (Chevy/GM), Cummins 6.7-liter (Dodge), and Powerstroke 6.7-liter are widely regarded as the best diesel engines for pickup trucks in 2021-2022.
When evaluating engines, horsepower is a typical criterion. People pay special attention to peak horsepower. Only when the engine reaches a certain number of revolutions per minute does it reach peak horsepower (rpm). The purpose of an engine is to generate and deliver power to the truck. As a result, more horsepower often equates to better acceleration and top speeds.
Torque is a another way of measuring power. Torque is the force required to propel a truck from a halt and to transport big cargo. Torque is measured in pound-feet, or lb-ft for short, as previously stated.
At 3,200 rpm, the Duramax 6.6-liter diesel engine produces 360 horsepower and 650 pound-feet of torque at 1,600 rpm. At 2,800 rpm, the Cummins 6.7-liter produces 385 horsepower and 865 lb-ft of torque at 1,700 rpm. The Powerstroke has 275 horsepower at 2,800 rpm and 525 pound-feet of torque at 1,600 rpm.
Remember that while fuel economy saves money on gas, it is also more expensive. Your truck’s fuel efficiency is also influenced by a number of other factors. Your truck will be less fuel efficient if you put an engine in it with a crew cab, extended bed, and other similar upgrades.
Comparing the base model of the Chevrolet Silverado 3500 (Duramax) against the Dodge Ram 3500 (Cummins) and the Ford 350 is one way to do it (Powerstroke).
The Silverado 3500 gets 17 mpg on the freeway, 23 mpg on the motorway, and 19 mpg on the highway (city and highway combined). The Ford F-350 gets 9 mpg, 15 mpg, and 11 mpg, while the Dodge Ram gets 13 mpg, 16 mpg, and 15 mpg.
Being a great engine requires a high level of dependability. When the engine is in the shop, performance is irrelevant. All three of the aforementioned engines are said to be trustworthy, but continue reading for more information on potential issues.
Because replacing an engine is expensive, longevity is crucial. All three of these engines are said to have a lifetime of over 300,000 miles. These models’ predecessor engines (those that have been on the road for more than a decade) have been reported to endure more than 500,000 kilometers.
What is the most reliable diesel engine for a truck?
The 7.3L Powerstroke is still widely regarded as one of the most dependable diesel engines ever produced. With 500 pound-feet of torque and 235 horsepower, it offers enough power for most purposes. With an air-to-air intercooler, oil-based fuelling, and long-lasting internal hard parts, it was built to last. When properly maintained, the Super Duty from 1999 to 2003 may travel much beyond 500,000 miles. If you’re looking for a secondhand 7.3L Powerstroke, you can get a fair deal on one with 150,000 to 250,000 kilometers.
Which is better Duramax or Cummins?
The Cummins engine is currently a 6.7-liter inline-six, whilst the Duramax is a 6.6-liter V8. The Duramax is the most powerful engine in terms of horsepower, but the Cummins is the most powerful in terms of torque, with values up to 1,000 ft-lbs depending on the truck.
What is the most reliable diesel engine ever made?
The 5.9L 12-Valve engine is designed to last a million miles. It came with a 230hp engine, 440lb/ft of torque, and an inline P7100 injection pump from the factory.
In the period of the 5.9 Cummins 12-Valve diesel engine, diesel enthusiasts were on the road. They could easily boost horsepower to over 500hp.
The 5.9L Cummins 12-Valve engine delivered excellent performance and fuel efficiency.
Is Cummins better than Powerstroke?
Although most diesel aficionados seem to agree that the Cummins Turbo Diesel is the more reliable engine, Ford pickups last longer and are more reliable than Ram pickups. The following are the most serious issues with these two engines:
On trucks with the CTD that do a lot of towing, the exhaust manifold issue with shrinking and cracking is most common.
The Powerstroke Diesel turbocharger issue primarily affects tuned engines, as the increased horsepower and torque causes the turbo’s ball bearings to wear out.
Why is Cummins better than Power Stroke and Duramax?
Pickup truck owners and buyers are frequently devoted to a single brand, and this is especially true with diesel truck buyers who purchase trucks solely on their engines. General Motors’ Duramax, Ford’s Power Stroke, and Cummins are the top three brands in the American diesel truck market.
The latter is mostly found in Fiat Chrysler’s (FCA) Ram 2500 and 3500 trucks, although its engines can also be found in Nissan’s Titan XD. FCA also owns VM Motori S.p.A., an Italian business that makes the EcoDiesel engine, a V6 with a 3.0-liter displacement that Jeep Wrangler began employing in its first diesel model a few years ago.
Is one engine superior to the other, or are there only minor differences? The best option is determined by the consumer’s needs. The following is a list of all the distinctions between these three diesel pickup truck brands.
Which Engine is Older?
Cummins was founded in 1919, and in 1988, it began supplying diesel engines to Chrysler Corporation’s Ram pickup vehicles. The GM Duramax range, on the other hand, has only been around since 2001. Since 1994, the Ford Power Stroke moniker has been in use. Even if you look past the GM and Ford engine brand names, Cummins is still older. When you compare Duramax engines to Cummins and Power Stroke engines, it’s clear that Cummins engines are the older of the two.
Which Engine Produces More Torque?
Towing is a major cause for the existence of huge, heavy-duty trucks. Torque is required for towing. Diesel engines may generate far more torque than gasoline engines. This is because their combustion process is longer and more consistent, allowing for longer connecting rods.
Due to a new fuel-injection system, the torque of the 2021 Ford F-Series Super Duty with the optional 7.3-liter 475-horsepower turbocharged V8 engine has been increased to 1050 lb.-ft (36K PSI). This is greater torque than the 6.7l Power Stroke turbodiesel engine in the 2019 Ford F-150, which produces 935 lb.-ft.
Meanwhile, the Duramax diesel engines in the 2021 Chevy Silverado HD and GMC Sierra HD are both capable of 910 lb.-ft. of torque. The 277-horsepower 3.0-liter turbodiesel engine in the 2021 GMC Yukon and Yukon XL produces only 460 ft.-lb. of torque.
The 6.7-liter Cummins turbo diesel engine in the Ram Heavy Duty, on the other hand, delivers 930 lb.-ft. of torque. The Ram 3500 Laramie, which is larger and more luxurious, produces 1,000 lb.-ft. of torque.
Apart from the smaller GMC, all of the domestic models have similar torque levels. Other elements, like as how much they weigh and how much optional equipment they must carry at all times, have an impact on performance.
What About Horsepower?
Torque is more crucial for towing than horsepower, but horsepower is equally important. Whether or not the truck is hauling anything, greater horsepower allows it to accelerate faster. You’ll welcome the extra horsepower if you need to accelerate rapidly while pulling a hefty load. Power Stroke and Duramax are fairly close in this category, with 450 for the former and 445 for the latter. Ram trucks use a Cummins engine that delivers 400 horsepower. Again, Power Stroke wins this category with the greatest horsepower, albeit by a razor-thin margin.
Torque and horsepower are important considerations when determining how much a truck can haul. Two other factors, though, play a role. The first is the truck’s structural design, and the second is the engine’s strength. Towing above 26,000 pounds in the United States, on the other hand, necessitates a commercial driver’s license.
The Ram Cummins and Ford Power Stroke can also tow that much, but the Duramax falls short with a total towing capacity of 23,300 pounds. The Power Stroke triumphs once more, with a total towing capacity of 34,000 pounds vs 31,210 pounds for the Ram. If you don’t have a commercial license and are looking at these stats, any of these trucks will certainly meet the needs of the average truck owner.
Is Cummins the best diesel engine?
Cummins diesel engines are known all over the world for being exceptional truck engines, not only because they provide the horsepower and torque a work truck requires to carry a heavy load, but also because they are known for their unparalleled durability.
Who makes the best diesel truck 2021?
As Chevy prepares a future vehicle for the market, the Chevrolet Silverado 1500 LTD is a carryover of the previous-generation Silverado. Due to its obvious elegance, accessible turbo-diesel engine, and user-friendly trailering technology, the old model is still in high demand. On road trips and other activities, the Silverado 1500 LTD also boasts the spacious interior that owners have always liked.
Which is better Cummins or Caterpillar?
Cummins has a strong technological advantage over the competition, according to Cramer, because the company is designing engines that are years ahead of future emissions regulations. For example, the business is already putting 2010-compliant on-highway engines through their paces.
Cummins engines outperform Caterpillar engines by 6% in terms of fuel efficiency. CMI isn’t the only one who excels in this area. It’s also stealing market share from CAT in other heavy-duty engines. Cummins is gaining market share from all of its competitors, and it is currently Paccar’s leading supplier.
