Demand for Chev Tahoe and Suburban Diesels Is Growing

How many manufacturers of full-sized SUVs offer a diesel engine alternative? Toyota does not. Nor does Nissan. And neither does Ford. GM alone seems to own this space with a trio of large SUVs -- the Chevy Tahoe, Suburban and the GMC Yukon. GM has evidently identified an unmet need that its competitors have neglected, or simply or created a demand that consumer have been waking up to.

According to the article in GM Authority, when GM made a decision to insert its 3.0-liter I-6 LM2 turbo-diesel Duramax into their 2021 Chevy Tahoe and 2021 Chevy Suburban, both models saw an increase in orders for the diesel engine option. And that is the point this article strives to bring home.

Whereas gasoline-powered full-sized Tahoe and Suburban SUVs still garner more than 90 percent of sales, the story is about the significant growth taking place in the diesel category. Sales numbers reflect the highest take rates since the Duramax became an option.

What is it that is causing this increased interest in the full-sized diesel SUVs? Some surmise that the SUV body styling is preferred over the Chev Silverado 1500 or GMC Sierra 1500, which both offer the same engine. There is certainly a place for each in the lineup. Different strokes for different folks, as they say.

The article proceeds to outline the special characteristics of the 3.0-liter LM2 Duramax engine, which features a duel overhead cam (DOHC) configuration and direct injection, enabling it to produce 277 hp at 3,750 rpm with 460 pound-feet of torque at 1500 rpm. For it size the fuel economy looks good, too. Both are "significantly more efficient" than their gasoline-powered counterparts.

When it comes to towing, the Tahoe diesel is able to tow more than four tons or carry a max payload of 1717 pounds. The Suburban likewise can tow four tons and carry a payload of 1,625 lbs. These are essentially workhorses dressed in their Sunday best.

As you might expect these brands have been keeping pace with the stylish requirements of a futuristic contemporary vehicle. Check our this interior shot of the cockpit. It's NASA Mission Control for civilians. 

Without a doubt the bottom line in this story is that diesel engines are being embraced by a broader portion of the market. The benefits have been increasingly recognized, and sales numbers are confirming it.

2021 Yukon Diesel Brings Back Memories of the Gold Rush Era

Shortly before the end of the 19th century, gold was discovered in an inhospitable corner of Northwest Canada. As word got out, more than 100,000 prospectors migrated there in what became known as the Klondike Gold Rush. The famous American author Jack London was one of these. Through stories like Call of the Wild and White Fang the rest of America learned how challenging and dangerous this terrain could be.

By understanding the Klondike, its terrain and its history, we might gain a greater appreciation for the the Yukon name when it was introduced in 1991 for the '92 model year. The terrain is rugged, and half the year downright treacherous. You have to learn how to be a survivor there or you're a goner. Hence the Yukon name speaks of a toughness the exceeds the normal.

The Gold Rush image speaks of value. When you "strike gold" it is something you longed for but seldom really expect. So the Yukon name goes along with a search for something of value, and perhaps the joy of finding it. 

One of the nice "discoveries" of this year's crop of SUVs was that of finding a new Duramax diesel engine under the hood of the 2021 Yukon. This story by Fox News focused on yet a third way that the Yukon parallels the Gold Rush of 1896-99, its temporary duration. The title of the article is The 2021 GMC Yukon Diesel is built for the long haul, but may be short-lived. The meaning behind these words is that yes, it is exciting to have a diesel Yukon, but by 2035 GM will only be producing EVs.

The article by Gary Gastelu begins by noting, "It’s the same 3.0-liter turbocharged inline-six-cylinder offered in the Sierra pickup and an alternative to the 5.3-liter and 6.2-liter V8s that are also available in both trucks." Then he switches gears to address the "Why now?" question. The answer is clear. Not everyone is ready to go electric yet. Gastelu cites a stat from the Diesel Technology Forum that diesel pickup and SUV sales were up 28% in 2020. 

After noting the excellent fuel economy of the Yukon the author highlights the hefty towing capacity. (8100 pounds with 2-wheel drive and 7800 with 4-wheel drive.) One gets the impression that Mr. Gastelu likes this compact big boy. 

After a look under the hood, the author takes us inside the cockpit with its unique interior dashboard design. The electronic goodies are many, but it all comes with a price. Then again, gold has value, and this Yukon does, too.

2021: What's New In Diesel This Year

A couple weeks ago Rick Popely assembled a story for Cars.com titled What’s New With Diesel Vehicles for 2021?

Popely begins with the disappointing observation of what is not new this year. If you love diesel power and fuel efficiency, you won't find it in a passenger car anymore. Diesel passenger cars are no longer an option in the U.S. market. Part of this pullback is due to recent scandals regarding emissions tampering, as highly publicized in a January NYTimes story. This issue has been a long time coming though. 

It's really too bad since, as Popely correctly notes, "diesels generate far more torque than gas engines, and that low-end grunt makes them the engine of choice for many who need to tow heavy trailers, so you’ll still see this powertrain option in truck and SUV lineups."

Fortunately, there are some pretty stylish SUVs on the market. As for the trucks, we have all the usual suspects, each one amping up their game to not only capture eyeballs but to satisfy the performance standards we've come to expect. Here's what's available for the year 2021. You should go to the Cars.com site (link below) to read about each in more detail and, if you're looking for something to buy, see what's available in your neck of the woods.

The 2021 Escalade and Escalade ESV

As we noted in January, this is the first year Cadillac has offered a diesel engine in more than three decades. The 2021 Escalade is completely redesigned. Both the Escalade and the stretched ESV offer a turbo-diesel 3.0 inline-six-cylinder power plant that delivers 277 horses and 460 pound-feet of torque. 

The 2021 Chevrolet Silverado

The Silverado 1500 has increased its towing capacity significantly for 2021. Not only that, this ability to tow more is going to cost less, almost as if we're being nudged into the diesel engine option. The 3500 has also bumped up its guidance for hauling. Additional features include some tailgate refinement and rear cameras, which have benefits as well.

The 2021 Chevrolet Tahoe/Suburban

Both the Tahoe and Suburban tout roomier interiors. Pickups have a long history of being workhorses, but a little cramped. This trend of making our "living space" inside the can more luxurious has been going on for quite some time.  Popely notes that the Suburban has an added 15 inches of length over the Tahoe, which initially doesn't sound like much, but can make a difference. Purportedly it has 22 more cubic feet for cargo than the Tahoe.

The 2021 Ford F-150

According to Edmund's the Ford F-150 has been the best selling truck and vehicle in America for 40 years. This year's Ford truck has six engine options and the truck itself has had a complete makeover. Popely notes that its more luxurious inside the cab and has a host of new features.

The 2021 GMC Sierra

As with all the others, we get options and more options.The turbo-diesel 3.0-liter six-cylinder gives you more power on the 1500 and the 3500 is no slouch either. Ultimately, the Sierra is described as an upscale Silverado. Which it is.

The 2021 GMC Yukon and Yukon XL

The Yukons share the same drivetrains as their GM/GMC siblings, but differ in style and interior treatment. In keeping with the desire for more space, these are designed to be roomier as well. There are noteworthy dashboard features cited in the Cars.com article as well.

The 2021 Jeep Gladiator

When we first wrote about the 2021 Jeep Gladiator in September we were jazzed by the engineering. The 4WD Jeep has fans coming back for more. 

The 2021 Ram Trucks

Popely makes observation about both the 1500 and the 3500. "The Ram 1500 adds a more efficient diesel model, the Tradesman High Fuel Efficiency EcoDiesel, with an EPA combined rating of 26 mpg, 2 mpg more than the best of the 1500’s other diesel models. On the heavy-duty side, torque on the Ram 3500's Cummins turbo-diesel 6.7-liter rises to 1,075 pounds-feet, and gooseneck towing capacity increases to 37,100 pounds, both best-in-class numbers.
