GM resumes production of its 3.0-liter turbodiesel straight-six

General Motors temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine in August 2021 due to a supplier shortage. Reports claimed the pause would last through 2021, but the engine is already back in production. Enthusiast website GM Authority learned from sources inside General Motors that the straight-six is once again coming off the assembly line at the Flint Engine Plant in Flint, Michigan. There's no official word on precisely what the problem was linked to and whether it was related to the on-going chip shortage that's wreaking havoc across the automotive industry. All we know is that the pause lasted for about two weeks. Called LM2 internally, the six is available in Chevrolet's Tahoe, Suburban, and Silverado 1500 and in GMC's version of these trucks. It's also an option in the Cadillac Escalade. It develops 277 horsepower at 3,750 rpm and a V8-like 460 pound-feet of torque at 1,500 rpm in every application, and it allows these big behemoths to post surprising fuel economy numbers. Fitted to a rear-wheel-drive Tahoe, the Duramax returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make it more efficient than a Blazer. Demand for the diesel-powered trucks is relatively high. While the shortage undoubtedly took a toll on sales, the Duramax represented 8% of Suburban sales and 6% of Tahoe sales in May 2021. There are no other diesel-burning full-size SUVs available new so they have the market to themselves. On the truck side, Ram still makes the EcoDiesel available on some 1500 trims but Ford abandoned the segment.

2018 Ford Expedition vs other big SUVs: How it compares on paper

With our Alex Kierstein rightly impressed in his first-drive review of the new 2018 Ford Expedition, we decided to dig a little deeper into the numbers, and we came up with the spreadsheet below to highlight how the new 2018 Expedition compares on paper to its main full-size SUV competitors: the 2018 Chevy Tahoe and Suburban (and therefore the 2018 GMC Yukon), 2018 Toyota Sequoia and 2018 Nissan Armada. We also threw in the new, even bigger 2018 Chevrolet Traverse since, as you'll see, its massive dimensions should put it on the radar for anyone who needs loads of passenger and cargo space but doesn't care as much about towing. A few notes about the chart above. First, the 6.2-liter V8 that's included with the new-for-2018 Tahoe RST trim level is the standard engine on the GMC Yukon Denali. You can apply most of the Tahoe's numbers to the entire Yukon and Yukon XL lineup. Second, though we highlighted categories where the Traverse led, we also highlighted the runner-up full-size SUV, since this was ultimately about that segment. Traverse numbers are broadly applicable to the new Buick Enclave.

Hummer EV SUV overland camper teased from GMC and EarthCruiser

At the end of March this year, GMC announced a collaboration with EarthCruiser. The automaker's Hummer team would work with the Oregon overlanding company's research and design division to develop an upfit for EVs, initially integrated into the Hummer EV pickup. For those not familiar with EarthCruiser, they’ve made wild overlanding vehicles like the Terranova, FX and EXP, pretty rad and pretty expensive stuff. The preview back then was a shadowy render that looked much like the silhouette of the Hummer SUV thanks to the living quarters slid into the pickup bed. The most apparent changes were solar panels integrated into the roof, and a cargo bay on the side of the slide-in. The duo's just put a much better tease on Instagram revealing the campfire-lit outline of what this version of an overland Hummer will look like. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. EarthCruiser is known for its pop-up roofs. This looks like a choice execution here, with near 360-degree visibility and integrated LEDs. Also, dig what looks like a platform off the back of the rig. We're going to guess that's either a slide-out or the rear flap on the camper top locked into the raised position. The cargo boxes on the side look neat, we look forward to finding out how they work and what they store. We also wonder if they'll be optional and whether they extend beyond the wheel arches, making a really wide pickup truck even wider.  We're not sure it will be "every overlanderÂ’s dream," but we are sure some stargazers are going to have some very sweet dreams in it. Slated for debut this month, look for it at Overland Expo Mountain West in Colorado, the same place the GMC Canyon AT4X OverlandX made its public debut in 2021, and where in Arizona last year the GMC showed the Sierra's outdoor potential with an Ultimate Overland Vehicle built on the Sierra 1500 AT4X.  Related video: This content is hosted by a third party.
