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.

2020 GMC Sierra 2500 HD and 3500 HD spied on public roads

We saw spy shots of the Chevrolet Silverado HD a short time ago, and now it looks like GM has got the 2020 GMC Sierra Heavy Duty trucks running around in public too. The one we're looking at here appears to be a 2500 Denali Crew Cab, distinguished easily by the same Denali grille on the 2019 Sierra 1500. Aesthetic differences between the front fascias on the 1500 and 2500 HD are small, but the 2500 is a bit more muscular in the hood and lower trim treatment. GMC doesn't look like it's hiding a whole lot with this camouflage, since the sheets over the grille and headlights are mostly transparent. The black tarp over what appears to be a hood scoop leads us to believe it will have the same type of hood design as the 2018 HD. Other interesting bits revealed here are around the rear of the pickup. We can see the same interface for the MultiPro six-way tailgate on this truck as the 1500, so at least the Denalis will have the trick tailgate (we'd expect every trim to have it, though). Just like we saw on the Silverado, the Sierra HD gets the stepside feature just ahead of the rear wheels. LED taillights are clearly visible through the thin veiling, and GM's rear steps remain as well. in addition to this 2500 HD, our spy photographers also caught a 3500 HD model. This one isn't a Denali, as the grille shows its hand again. The grille is different than any of GM's designs on the new trucks we've seen thus far, actually. GMC showed us a teaser of what a new Silverado HD grille would look like months ago, but this differs even further than that. It looks rather minimalistic under the sheet for now, with strong horizontal slats. The actual shape and design of the truck is revealed for the most part, since it's just wearing a thin body wrap. Its mirror design appears to be different from last year's, as the arm is completely solid. A sidestep right in front of the rear wheels carries over from the 2500 HD too. We imagine both this truck and the Silverado HD will debut early next year during auto show season. Related video: This content is hosted by a third party.

2024 GMC Acadia gets bigger, goes entirely turbocharged

For an entire generation now, the GMC Acadia, the brand's largest unibody SUV, has sat in an unusual zone in between the typical midsize two-row and large three-row segments. But the completely redesigned 2024 Acadia is stepping confidently into the latter camp, growing to roughly match its cousin, the also fully redesigned 2024 Chevy Traverse. And adding to its greater size and performance, the Acadia brings unique exterior and interior design. The size increase is impressive. The wheelbase has grown 10.6 inches, overall length by 8.4, and overall height by 3.2. GMC claims this has increased cargo space by 80% and second-row seat room by 27%. These changes all make it about the same size as the Chevy, too, instead of a smaller option.  This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. That doesn't mean the two look the same, though. The front fascia clearly borrows heavily from the GMC Sierra 1500 with a tall grille and C-bracket headlights. The flanks really depart from the aggressive shape of the Traverse. It also skips the fat C-pillar. GMC designers noted they specifically worked to reduce the size of that pillar, in part to improve visibility for third-row passengers. Conversely, the D-pillar is relatively large and is finished in body color to reveal it. But to keep it from looking overly large, there's a black plastic panel that helps give the rear window a bit of a wraparound effect. The taillights also have a gloss black panel to blend them into the rear window area and reduce the visual mass of the hatchback. The interior is the biggest differentiator between the Traverse and Acadia, though. The entire dashboard is unique to the Acadia. The 11-inch instrument display sits under a cowl that extends horizontally to meet the unique vertical 15-inch infotainment screen. That screen overlaps a squared-off, horizontal dash design, and it's flanked by vertical air vents. The Acadia picks up a column-mounted shifter, too, freeing up space for storage in the center console. There are practically no parts directly pulled from other GM products. And unlike GM's upcoming EVs, the Acadia will have Apple CarPlay and Android Auto functionality. Individual Acadia models even have unique features. The luxury Denali trim and off-road focused AT4 trim both return. The AT4 stands out the most with an extra inch of ground clearance in part from the all-terrain tires on 18-inch wheels.
