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.

Cadillac XT5 caught uncovered during photo shoot

It's only been a few weeks since Cadillac announced that its replacement for the SRX, the new XT5, is on its way. Now, we have images of it out in the open and completely free of camouflage. Obtained by a reader at Jalopnik's Opposite Lock forum, the Caddy was spotted during what user Saw930 believes was a photo shoot in New York's trendy SoHo neighborhood. There's only a pair of images, from the front and rear three-quarters, but it's enough to give us a very thorough overview of the exterior styling on the new CUV. In short, the design language that has been seen on Escalade, CTS, and upcoming CT6 has indeed made its way to the SRX replacement. The broad, egg-crate grille is perhaps the cleanest iteration of Caddy's latest styling, while the CT6-inspired headlights look sharp, as well. Expect a similar headlight pattern to the CTS, with strong LED character accents on the outside of the headlights that integrate seamlessly with the lower DRLs. In back, the taillights curve over the rear haunches and blend into an extremely strong shoulder line. It's a dynamic and aggressive piece of design that we'll need to see in person before signing off on. The rear bumper, meanwhile, is a nicely styled piece, complete with twin, integrated, rectangular tailpipes that flank a piece of (probably faux) skid plating. There's a similar off-road treatment in the front bumper, as well. While we wait for scour for more news on the XT5, have a look at the two images Saw930 captured and posted at Oppo and let us know what you think in Comments.

GM says EVs are the future — but trucks are going to take it there

In the PowerPoint deck for the General Motors Capital Markets Day presentation, one of the more disturbing things comes early on, during GM President Mark Reuss' initial remarks, in an area where he is discussing the company's overall strength in trucks. The point being made is that GM has a truck for all and sundry. And there it is, a phrase on a slide that should send chills up the spines of those who still pine for the old Bob Seger "Like a Rock" Silverado ads: "Little bit country. Little bit rock 'n' roll." That's right. Donny and Marie. Somehow the Denis Leary snark in the F-150 ads is all the more appealing. The Capital Markets Day presentation was chock full of observations about electrification and automation (Reuss and CEO Mary Barra both noted that the corporation's vision is one of "Zero Crashes. Zero Emissions. Zero Congestion." Dan Ammann talked about the progress being made at Cruise Automation; Reuss rolled out the plan for an array of electrified vehicles, with a luxury EV and a compact SUV being the "Centroid Entries" for the modular bases of many others). But it is worth noting that there is no getting away from the power of pickups in the U.S. market, as that was the central topic in Chief Financial Officer Dhivya Suryadevara's comments, with "Truck Franchise" being flanked by "Key Financial Priorities" and "Financial Outlook." Clearly, to gloss the old phrase, the truck segment is where the money is. Suryadevra enumerated how the truck segment is significantly different than other types of light vehicles. Among her points: GM, Ford and FCA have more than 90% of market share. The truck parc has been growing and aging over the past 10 years. Customers are fiercely loyal to the segment—as in 70% of truck buyers are truck buyers. A good number of the vehicles are for commercial use (40 percent). Trucks are "less prone to. . .mobility disruption." Trucks offer high margins. Translaton: The segment is one that they're solidly positioned in. There are lots of old trucks on the road that will need to be replaced by new ones. Perhaps buyers may switch from a Sierra to a Canyon, but it will be a truck. If your livelihood depends on that type of vehicle, even if gas prices go up or the economy begins to go south, you're going to stick with it. Most of the country isn't San Francisco, so trucks will continue to be essential. And, well, they're profitable in the extreme.
