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.

GMC Hummer EV hits Neiman Marcus Christmas catalog for twice the price

This winter season, Nieman Marcus is getting into the true meaning of Christmas by offering a bunch of seriously expensive stuff in its annual holiday catalog. There's usually at least one automotive offering, and this year it's a 2022 GMC Hummer EV Edition 1 for an eye-watering $285,000. That's $172,405 more than the regular Edition 1 crab-walker, which is priced by GMC at $112,595. And what does one get for more than 2.5 times the cost of the most expensive electric Hummer? Well, hold your 1,000 horses, because this isn't just any Hummer EV Edition 1. No, it's a one-off Barrett-Jackson Hummer EV Edition 1. The interior of this Barrett-Jackson edition Hummer has been "curated" by Craig Jackson himself. And by curated, they mean it has a bunch of red trim everywhere and is garnished with a Neiman Marcus logo. Aside from that, there is nothing appreciably different about it. No performance upgrades, no special paint job. You do get an electric charging station at home, though, which might be the most useful addition to this whole enterprise. If that's not worth the price of an entire 1.5 extra Hummers to you, there's more. You get two VIP passes for the opening gala of the Barrett-Jackson auctions in exotic Scottsdale, Ariz. During the auction, you'll get access for two to Carolyn and Craig Jackson's personal skybox from where you can watch 1,500 cars trade hands. But don't get too comfy, because at some point you'll be invited on stage to receive your Hummer EV in front of a gaggle of inebriated fishing boat dealership owners. Oh, and you'll also get to bang the little auction hammer. You can pair the Hummer with other gifts in Nieman Marcus' "fantasy" catalog, like a $6.1 million dollar diamond ring. However, if you go with the $395,000 Great Gatsby-style roaring '20s party, make sure it doesn't end with the 9,000-pound Hummer Daisy Buchanan-ing any bystanders.

GM removes start/stop from full-size trucks and SUVs with V8 engines

GM is removing start/stop technology from a number of its popular full-size SUVs due to the ongoing chip shortage. This follows the removal of cylinder deactivation technology from some of its trucks, which was also due to the chip shortage. GM Authority first reported the news, but we’ve just confirmed everything with a GM spokesperson.  The following 2021 model year vehicles will be affected: Chevy Tahoe, Chevy Suburban, GMC Yukon, Cadillac Escalade, Chevrolet Silverado 1500 and GMC Sierra 1500. Only versions of those vehicles built with the 5.3-liter V8 or 6.2-liter V8 and mated to the 10-speed automatic will have the tech removed from them. Only vehicles manufactured on or after June 7 will be affected. “By taking this measure, it will enable us to continue production of our high-demand full-size SUV and pickups as the industry continues to rebound and strengthen,” GM said in a statement. Those who ultimately buy one of these vehicles without start/stop technology will receive a $50 discount off MSRP for their troubles. Losing this fuel-saving tech could be a big negative for some, but we know many folks turn it off anyway. Not having to press the button to deactivate start/stop every time could actually be a positive if youÂ’re part of the camp who does that already. 2021 Cadillac Escalade Sport Platinum View 27 Photos On the downside, GM says “most of the affected vehicles will experience a minor reduction in fuel economy.” We donÂ’t have revised window stickers in hand to know how each model will be affected, but any 1 mpg reduction will be rather impactful for vehicles rated as low as these trucks already are. Any reduction will be seen in the city mpg rating, so take the kind of driving youÂ’re going to be doing into account before purchasing. When it comes to greenhouse gas compliance rules, GM says it doesnÂ’t foresee this impacting the companyÂ’s average fleet score. It also intends to begin adding start/stop back to these models as soon as possible, but there will be no retrofit effort made to fit the tech to vehicles already built without it. “Our supply chain organization continues to make strides working with our supply base to mitigate the near-term impacts of the semiconductor situation,” GMÂ’s statement reads. “GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including our highly profitable full-size trucks and SUVs for our customers.
