GMC Lands Two on US News & World Report's List of 13 Most Powerful Diesel Trucks

GMC Sierra 1500 -- standing strong in 2021.

Making lists -- whether Top 10 Video Games or Top 100 Album Covers -- seems to be one of those things we never weary of. Top 10 state colleges. Top 5 investments for coming out of the pandemic. Billboard Top 100 for any year. Forbes' Top 400 Billionaires always grabs a lot of eyeballs. And the subject of this blog post, U.S. News & World Reports' Most Powerful Light-Duty Pickup Trucks of 2021.

My first thought in reading this list is to ask, "Why 13?" The answer that comes readily to mind is that by making the list longer, it can be more inclusive. Thus, U.S. News & World Report is able to include Nissan, Toyota and Honda offerings, in addition to the major U.S. manufacturers' offerings. 

In this post I want to introduce the two GMC trucks, then close by listing the top five on USN&WR's powerful trucks list.  Number 8 on the list is the 2021 GMC Canyon AT4 Off Road Performance Edition. The GMC Sierra 1500 muscled its way into the Number 3 slot.

GMC Sierra 1500
The truck division of General Motors covers a lot of territory. GMC makes military vehicles, motorhomes, SUVs, vans, buses, and trucks--heavy duty, medium-duty and light duty. This year's Sierra is available with five engine options, out favorite being the Duramax 3.0-liter Turbo-Diesel. This engine produces 277 horsepower and 460 lb-ft of torque. 

If you know your Spanish, you might be aware that the word sierra means saw. We've come to associate it with mountains, but those High Sierras and Sierra Madres obtained their names from their ragged sawtooth appearance. GMC adopted the name to no doubt correspond to the rugged requirements for vehicles in this kind of terrain.

In addition to the engine options, the Sierra comes with three different drivetrain options that correspond with engine selection. GMC also offers buyers three different can configurations as well. Just looking at this truck, with is expansive grille and staunch design, gives you the impression that it's ready and able to go to work.

2021 GMC Canyon 

Like the Sierra, the Canyon also has a name that speaks of ruggedness. The GMC Canyon took a respectable 8th place on the USN&WR top 13 list. This truck has three engine options. It's Duramax Turbo-Diesel is a four-cylinder power plant that puts out 181 horsepower and 369 lb-ft of torque. This is a more compact machine that one can dress up with trim options.  

Car & Driver summed up its take on the Canyon with this verdict: "The Canyon has fancier styling than its Chevy sibling, but they both have tremendous capabilities."

The Top 5 
Here are the five USN&WR selected as their highest rated favorites, though all of these trucks have been turning heads and pulling strong reviews. 

(5) 2021 Nissan Titan

(4) 2021 Silverado 1500 

(3) 2021 GMC Sierra

(2) 2021 Ford F-150

Numero Uno: 2021 Ram 1500

GMC liked seeing both these trucks make the USN&WR Top 13 Powerful Light Duty Trucks list. This blog post was inspired by a story highlighted on The News Wheel website.

New Cummins Diesel Engine Fires Off Fabulous Numbers: Clean Diesel Keeps Getting Cleaner with a Little Help from Silicon Valley

Cummins X15: expanding diesel's possibilities.

A recent story by Michael Coates in the Clean Fleet Report was reprinted on SHIFT, a website devoted to sustainable mobility. The article is about Cummins' efforts toward clean diesel.

The author begins by noting what we've been saying many times. There are seemingly countless articles claiming that the internal combustion engine is dead or dying. While investors are throwing their money behind EVs, there are significant advances taking place with the internal combustion engine. While the world prepares for an electric future, there are great strides being made in the realm of diesel.

Coates writes: "While 2045 may still be more that two decades away, emissions advances in internal combustion engines (ICE) are continuing. A new technology may take the already quite clean (especially compared with engines of just a little more than a decade ago) engines to a level that reduces smog-producing emissions while increasing fuel economy and yet not losing any performance."

The new engine concept is a joint effort by Cummins and a Silicon Valley tech innovator, Tula Technology. The two firms  released a study this past month showing how Tula's diesel Dynamic Skip Fire (dDSF) technology reduced NOx by 74% and CO2 by 5% when applied to a current Cummins engine. The Tula software uses algorithms to fire or deactivate a given cylinder on a cylinder event basis. As a result it is able to control exhaust temps that are critical for optimizing emissions control equipment. It reportedly clicked off a savings of 20% in fuel. 

The specific Cummins diesel was the X15, a state-of-the-art engine used in many Class 8 trucks. dDSF is essentially a micromanager of the engine's cylinders. The engine was first put through the paces on the dyno and then road tested, testing that is ongoing. 

According to the Clean Fleet Report, Cummins is not the first to employ dDSF technology. GM began working with Tula in 2018. The joint effort with Cummins, however, has now been going on for a year or more.

The selection of the X15 was quite intentional. This is Cummins' most fuel efficient diesel engine in the Cummins lineup and possibly the most fuel efficient they've ever produced. The target for this Tula-Cummins team-up is to hit 2024 NOx standards without losing this fuel-efficiency milepost.

For long haul trucking fleets that average 100,000 miles a year, even the slightest gains become significant when added up. This is just one more event in an ongoing series of incremental improvements through the application of technology. We look forward to the road ahead.

How to Read Diesel Smoke Signals

In early April, XDP published a useful tech talk article on how to diagnose what's going on in your engine by what your smoke is telling you. This article is a brief summary of the highlights from that story. We'll include a link at the end here so you can read further.

The article begins by stating flat out that there should be no smoke coming out of the tailpipe of a properly running diesel engine. The exception might be a small burst of black smoke upon acceleration in older diesels.

If you do have smoke, it will be either black, blue or white.  

Black Smoke is indicative of a problem with the air/fuel ratio. The culprit is often the fuel injectors, though not always. Fuel injector issues can include damaged nozzles, worn parts, over-fueling or incorrect injector timing. Sometimes there's a problem with injectors sticking open too long with common rail diesels.

Other areas to explore with a black smoke problem include clogged air cleaner, malfunctioning turbocharger, faulty injection pump, low compression, sludge buildup, excessive carbon in the intake manifold, and even low quality fuel.  

White Smoke will signal a different set of issues. Often it means that not enough fuel is being burned, or that unused fuel has slipped through to the exhaust. It could also mean that your engine is too cold on startup, or that coolant has somehow seeped into the combustion chamber.

With white smoke you may also have an injector issue, either damaged or incorrect timing. Other potential issues can include damaged rings or cylinder liners, water in the fuel due to a head gasket leak, low cylinder compression, malfunctioning glow plugs, or even a fuel pump issue.

Blue Smoke is the least common of the three.  It means you're burning oil in your engine. Not good. Underlying causes can include damaged, worn or sticking rings, damaged or worn cylinders, oil too thin for your application, worn seals, too much oil in the engine or a damaged lift pump. 

Whatever the cause, excess smoke is not something you really want to see. Here's the full article at XDP: Diesel Smoke Diagnosis

Today is Memorial Day. To all veterans, current service members, and their families – thank you.

Memorial Day: A Day for Honoring Those Who Have Served

Memorial Day, which usually falls on the last Monday of the month, falls this year on the very last day of the month. Most of us are aware that Memorial Day was designed to honor the men and women who have died in the service of our country. Did you know that the entirety of May is National Military Appreciation Month? It is a season for honoring our veterans and military communities for their service to our country. 

This holiday, which began after the Civil War, was originally called Decoration Day. On the first official Decoration Day, General James Garfield gave a speech at Arlington National Cemetery. 5000 people helped lay decorations on the graves of 20,000 Civil War soldiers who were buried there. 

It wasn't until 1971 that it became an official national holiday, making this year the 50th anniversary of this official designation. Many Americans observe this day by visiting cemeteries, holding family gatherings and participating in parades.

Throughout this last weekend of Military Appreciation Month we want to make time to honor our veterans and all those associated with the military for their service to our country. 

We're grateful for your dedication to preserving our freedom and making this world a better place. To each and every one of you: Thank You.

Champion DOT 5 Brake Fluid is Purpose-Built for Classic, Antique and Collector Diesel Vehicles

When we think about the vehicles we've loved over the years, a host of memories might pop into our heads. Speed, style, cruising, drive-ins, exploring trails, drag racing and a host of other memories compete for attention. 

I'm willing to bet, though, that brakes were not part of most of those reflections. Yet, brakes are as essential as the diesel engine that rumbles under the hood. When you want to go, you gotta know how to stop as well.

This week Champion Brands announced a DOT 5 brake fluid specifically designed for classic antique and collector diesel vehicles. Here's the story I saw.

Champion DOT 5 Brake Fluid is Purpose-Built for Classic, Antique and Collector Diesel Vehicles 

Champion, a globally recognized industry leader in specialty products for over 65 years, has recently introduced Champion DOT 5 Silicone-Based Brake Fluid.

The new fluid is a polysiloxane-based fluid designed for use in non-ABS hydraulic braking applications. It was developed to be used in older gas and diesel vehicles where moisture will be prevalent and unavoidable due to lack of use.

Brakes run on a hydraulic system that requires fluid to make them work. Placing your foot on the brake pedal transfers pressure through the brake fluid to the brake calipers which then apply pressure to the brake pads and rotors or the brake shoes and drums.

This process creates friction that stops the vehicle and, in some applications, creates heat. Different brake fluids react to heat in different ways, which is why there are different types of DOT brake fluids available. Dot 5 has a very high boiling point and has more compressibility than most glycol ether-based fluids.

Champion DOT 5 Brake Fluid (Part #4055) is a silicone-based high-temp brake fluid used primarily in applications like gas or diesel classic, antique and collector vehicles which are primarily kept in storage or used only occasionally. It will not blister, peel, or harm painted surfaces and acts as a weather barrier for your brake system, preventing rust.

Unlike glycol-based fluids, Champion's silicone-based brake fluid has a much more consistent viscosity profile, thereby providing excellent lubrication of brake system components -- leading to more consistent brake feel and longer component life. A Champion DOT 5-filled brake system will last longer and works well in cold temperatures.

Do not use Champion DOT 5 Brake Fluid in ABS-equipped braking systems. When DOT 5 brake fluid is used in an ABD system it will become foamy and unreliable. This is a result of the pulse high-pressure action that ABS brake systems exert on air bubbles, greatly reducing the reliability of the brake fluid.

There are some other systems that may not work with silicone brake fluids because of the chemical composition of silicone rubber external components, such as caliper piston boots. DOT 5 brake fluid could break these down. 

Champion DOT 5 Brake Fluid does not mix with DOT 3, DOT 4, DOT 5.1 or racing brake fluids.

Champion DOT 5 Brake Fluid Properties
Purple liquid
Dry boiling point: 530 degrees
Viscosity: 900cSt @ -40°F 
Conforms to FMVSS 116 (DOT 5) and MIL-PRF-46176B
Contains Polydimethylsiloxane, Tribultylphosphate and Dioctyl-Sebacate

Hauling Away Garbage with Clean Diesel in Miami-Dade County, Plus Four Takeaways

EPA to upgrade Miami-Dade County waste removal fleet.

Garbage disposal is a big part of our lives that we pretty much take for granted. It's hard to imagine where we'd be if we simply piled up our trash in the back yard. Apartment dwellers would be in an even bigger predicament. 

Waste removal is as old as civilization. Before motorized transports, people hauled their solid waste to the dump in wagons. The first motorized dump truck was produced by the Thornycroft Steam Wagon Company in England in 1897. Garbage trucks saw increased deployment in the 1920's. Initially they were open on top. The foul odors soon led to the revolutionary enclosed style that we're all familiar with today.

Here's an interesting story from Waste Today. Miami-Dade County has won a grant for $1.9 million from the EPA to upgrade their a portion of their waste removal fleet to cleaner diesel. The grant will enable them to purchase 25 new vehicles, 23 of them side-loaders, the article said. The grant will be used for replacing older vehicles that cough pollutants into the atmosphere. The new clean diesel technology will significantly reduce emissions. 

For decades garbage removal vehicles have been diesel-powered beasts of burden. Their muscular ability to haul tons of trash to landfills, as well as their durability over their long stop-and-go lifespan, made diesel the logical power plant of choice for these vehicles. 

This specific grant was awarded through the EPA's special program called the Diesel Emissions Reduction Act (DERA) with its ongoing mission for a "clean and healthy environment and clean air." 

“This grant from the EPA is an important step forward to build a more sustainable Department of Solid Waste Management, reducing emissions and protecting our environment as we serve our neighborhoods," said Miami-Dade County Mayor Daniella Levine Cava.

are recognizable because they revolve around a single basic concept. 

TAKEAWAYS  
There are a number of important takeaways for the diesel community in this story.  

1. The EPA recognizes that diesel continues to play an important role in our world today and that diesel will continue to do so. If the EPA is investing in the employment of diesel technology today, it is sending a signal that diesel will not be suddenly gone tomorrow.

2. Local politicians like any help they can get from Federal government to make their communities cleaner. Clean diesel reduces toxic emissions and politicians like to be associated with progress of this type. 

3. While EVs capture headlines in the larger media, diesel power remains the humble, unheralded workhorse that keep America going -- delivering vaccines, transporting our necessities, removing our trash. Fans of diesel tech have much to be proud of, nothing to be ashamed of.

4. When you hear that there's money on the barrelhead for upgrading equipment, go for it. You can't always get what you want, but sometimes you get what you need.

The Diesel High Performance Truck Market Is Still Growing

President Biden puts F-150 Lightning through the paces.

It has to be fun to be a president. Fun might not be the most apt word when you think about hostile critics and the need to have a thick hide. Nevertheless, there are some perks that come with the job. For example, last week President Joe Biden took a ride in the new EV Ford F-150 Lightning. His little cruise on the Ford test track made headlines across the country.

That news story brought to mind another story that got headlines when Teddy Roosevelt was president at the beginning of the last century. Roosevelt had approved the development of a new submarine for the U.S. Navy. It was called The Plunger. Some people were critical of the submarine as a weapon because it seemed un-American to use stealth to sneak up on enemies rather than fight face-to-face.

When the submarine was completed and tested, the president used his executive authority to go take it for a spin. That is, President Roosevelt wanted to see what it was like to be submerged underwater, to check it out and experience it first hand rather than simply get reports from the captains. The day he went out there was a storm, but with the Plunger twenty or forty feet underwater (depending on which account you read), it was a perfectly smooth excursion, ever though the surface was turbulent.

There were critics (this is where the thick skin is useful) who castigated him for risking his life for a unique nautical expedition. Nevertheless, he thoroughly enjoyed the experience.

ALL THIS CAME TO MIND as I read about a new report on the global growth of the diesel high performance diesel truck market. EVs are making headlines, but analysts who look at what is really happening (as opposed to what is generating buzz) acknowledge that the diesel market is still in a growth mode. 

An April MarketWatch report states that the diesel engines market was $7,921 million in 2019 and will be $9743 million in 2025. Part of this growth is driven by a surging demand in construction and auxiliary power equipment. 

Another report by Industry Growth Insights is projecting continued growth through 2028. Though their data analysis sees a tapering of the growth rate, the diesel engine market will not see a decline for quite some time. A report by The Shot Caller has similar expectations. Their report predicts growth to the end of 2026, with an implied continuation into 2027. 

No one can say for sure how quickly the adoption of EVs will occur. For now, there's limited infrastructure and a multitude of hurdles for EVs. 

The news stories regarding the unveiling of the EV Ford F-150 Lightning have focused on Ford's bold embrace of the EV future, making a risky bet on their number one selling truck. There's another side to the story, however, which we covered earlier this month. Ford engineers are developing a new diesel engine design utilizing an old-style concept. (See The Next Ford F-150)

In other words, Ford management is preparing for a future that can go either way. For now, the need for diesel power is continuing to grow, and the leaders recognize this.
