GM pauses 3.0-liter turbodiesel production due to a supplier shortage

General Motors confirmed it has temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine. It blamed the last-minute pause on a supplier-related shortage. Website TFL Truck first reported the news, and a representative from General Motors quickly confirmed it. The spokesperson explained the issue is due to a "temporary part shortage" and added that production will resume "as soon as possible," meaning the Duramax engine (which is called LM2 internally) is not going away permanently. Additional details are not available, so we don't know if the issue is related to the ongoing chip shortage. Rather than delay deliveries and create a backlog, General Motors is reportedly asking its dealers to encourage buyers who want a turbodiesel engine to instead select either the 5.3-liter V8 or the 6.2-liter V8, depending on the model selected. Both are gasoline-powered units. There's no word yet on when Duramax production will resume. The shortage affects several models, including Chevrolet's Tahoe, Suburban, and Silverado 1500 and GMC's variants of these trucks. Cadillac's Escalade is temporarily diesel-less as well. Heavy Duty variants of the Silverado and the Sierra are not affected because they're powered by a different Duramax engine with eight cylinders. Motorists seeking a full-size SUV powered by an efficient turbodiesel engine are temporarily out of options because the Tahoe/Yukon and the Suburban/Yukon XL had the segment to themselves. The Duramax was surprisingly popular, too: in May 2021, GM Authority reported that the turbodiesel straight-six represented 8% of Suburban sales and 6% of Tahoe sales. Installed in a rear-wheel-drive Tahoe, the engine returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make the body-on-frame behemoth more efficient than the unibody, front-wheel-drive Chevrolet Blazer that's 20 inches shorter and approximately 1,700 pounds lighter.

2022 GMC Sierra Denali Ultimate Interior Review: Better by a million miles

We were right. So were customers. Basically, everyone who took one look at the interior of the current GMC Sierra/Chevrolet Silverado generation and immediately went "not good enough." Possibly followed by "not even close" and/or laughing. The Silverado cabin was especially egregious in the top-of-the-line Sierra Denali, which slapped some token bits of "wood" to the doors and center console sides and called it a day. It didn't even get the Silverado High Country's bronzey trim surrounding the touchscreen. Absolutely nothing about it said, "I am competitive with just about any Ram 1500 or, to a lesser extent, a Ford F-150 King Ranch or Platinum." That changes with the 2022 GMC Sierra. Do I really need to explain why the "After" (up top) is so much better than the "Before" (above)? I do not. The better question is: is it better or at least as good as the Ram and F-150 now? Yes! And! GMC actually upped the game further for 2022 by adding a level beyond the Denali: the Denali Ultimate. While both Denalis share a common design with each other and the also-new Sierra AT4X, that design is different than what you'll find in other Sierras and every redone Silverado. Please correct me if I'm wrong, but this is the first time the Silverado and Sierra have had such substantially different interiors. True, they're still awfully similar, but by GMC/Chevy standards, it might as well be night and day.  You can see the difference below: Denali Ultimate left, Silverado High Country right. Is one design better than another? I don't think so, but they are indeed different, which is great. BUT! Remember, this is the new Denali Ultimate we're talking about here. That means it goes beyond the regular Denali.  First, this "Alpine Umber" color with "Forge perforated leather seat trim" is only available on the Denali Ultimate and the only color available for the Denali Ultimate. It has a bit of the King Ranchy/Long Horny feel to it without going so far into cowboy land. I dig it. The regular Denali offers Jet Black or "Atmosphere/Brownstone" (shades of brown).  This leather then features white piping and super-cool baseball-ish contrast stitching. I would like to reiterate at this point that the Sierra Denali's previous idea of a luxury aesthetic upgrade was strips of wood-looking plastic. What's the word I'm searching for? Ah yes. "Effort." But wait, there's more!

The GMC Hummer EV could spawn a smaller electric truck

Over 90,000 motorists have reserved a GMC Hummer EV, and the truck's relative popularity has convinced executives to consider launching a smaller and presumably more affordable model. While nothing is official yet, the Hummer EV's smaller sibling could be a midsize pickup. Citing "people familiar with the matter," Automotive News reported a smaller Hummer EV exists in the design studio that General Motors operates in California. There's no word on what it looks like yet, though it presumably borrows at least some of the rugged-looking styling cues that characterize the controversial, 9,200-pound truck. Interestingly, the smaller model could bring the Hummer name to Europe. It's too early to provide technical specifications. The model hasn't received the proverbial green light for production but Automotive News added that it's a "priority project" and that it has "a good chance of going into production." If and when it does, it's reasonable to assume the truck will use the Ultium battery technology found under the full-size Hummer EV, among other electric models from General Motors. GMC hasn't commented on the report, and it hasn't announced plans to launch a second Hummer-branded electric pickup. If the report is accurate, the baby Hummer is at least a couple of years away from hitting showrooms. First, the Hummer EV SUV will enter production. We've been here before: a downward expansion is exactly how the now-defunct Hummer brand was born. The military-bred H1 spawned the H2 for 2002 and the H3 for 2006. An even smaller off-roader previewed by the 2008 HX concept was planned but ultimately canned. Related video: This content is hosted by a third party.
