Redesigned 2021 GMC Yukon gets a diesel, AT4 model, Denali-exclusive interior

GMC's most robust family hauler is getting a complete redesign for the 2021 model year, including a new, off-road centric AT4 model, an upscale interior exclusive to its luxurious Denali model, an available air suspension, and, last but not least, a diesel engine.  With Americans obsessing over trucks, it's no surprise that GMC is going hard with its AT4s-for-everybody strategy; the Yukon is no exception. This will be the first model year for the new trim on GMC's largest SUV. This off-road model gets all the goodies you'll need to veer off the beaten path with confidence, including an extra 2.0 inches of ground clearance with the adaptive suspension option (more below), a two-speed transfer case, standard Goodyear all-terrain tires, an off-road mode for GMC's "Traction Select" drive mode system, hill descent control, and some extra underbody skid plates. Since GMC is a premium brand, even the AT4 gets some luxury appointments, such as a heated steering wheel, heated and ventilated front seats, and heated outboard second-row seats. The interior is also adorned in black leather with tan accents and "AT4" embroidery in the seat backs.  Speaking of premium, GMC will introduce an air-ride adaptive suspension with an off-road ground clearance mode as a late-availability option for several Yukon models, and this feature will be included on the Denali trim.  The Yukon and Yukon XL are GMC's variants of Chevrolet's full-sized SUVs, the Tahoe and Suburban. Their fundamental body-on-frame architecture is also shared with GM's half-ton pickup trucks, and thanks to that common engineering, they can also share powertrains. That's normally just a trivial side note when it comes to a new GM SUV announcement, but this time around, it's a bit more meaningful thanks to the introduction of a new light-duty, inline-six diesel in GM's truck lineup last year.  Yep, that means that for 2021, like the Tahoe and Suburban, the Yukon is getting a diesel option. The 3.0-liter Duramax makes the same 277 horsepower and 460 pound-feet of torque as it does in GM's trucks.  GMC's standard engine is still the 5.3-liter V8 that makes 355 hp and 383 lb-ft of torque. The 6.2-liter V8 is also an option like before, producing 420 hp and 460 lb-ft of torque. All engines come with a 10-speed automatic and a choice of rear- and four-wheel drive.

GMC Acadia goes big again? Spy photos show next-gen prototype

GMC is testing what looks a lot like a new full-size SUV, signaling the likelihood that it will return to full-size segment after the current generation has run its course. GM downsized the Acadia for the 2017 redesign, carving nearly 10 inches off its length and 3 inches from its girth. For the next generation, it appears that script will be aggressively flipped.  The hierarchy of GM's unibody family SUVs was already a bit wonky before the Acadia's 2017 redesign, and continues to be now. While it would be logical for the Chevrolet Traverse, GMC Acadia, Buick Enclave and Cadillac XT6 — all three-row crossovers — to be different skins on the same fundamental chassis, that's not actually the case. The Acadia is a full foot shorter than either the Traverse or Enclave, with the XT6 falling in between. Based on these photos, that will no longer be the case when the new GMC Acadia debuts. Since the current one went on sale in 2016 as a 2017 model, it's about due for a replacement.  We can't see much beyond basic proportions here, but those tell a clear story. It's pretty obvious that the hood on the prototype is wider and sits higher than on the current car, with perhaps less slope to the now-wider nose. We can also see the faintest impressions of creasing on the flanks, likely leading to the same broad, angular hip treatment present on the current car. Viewed side-by-side, we can see a little more front and rear overhang. There's no obvious hint of substantially longer wheelbase here (the rear doors line up almost perfectly), so we're probably looking at something that is wider but not necessarily much longer.  In any event, we shouldn't have to wait too long to find out exactly what GM has in store for its "Pro" brand.  Related video: This content is hosted by a third party.

Train derailment leaves Jeep, GMC, Chevy pickups damaged in Nevada

An unfortunate train derailment is causing some inevitable delays for pickup truck customers west of Nevada. Yesterday morning, 33 train cars derailed in Lincoln County, and the cargo that was being transported consisted of new Jeep Gladiators and Wranglers along with Chevrolet Silverados and GMC Sierras, judging from the photos released by the Lincoln County Sheriff’s Office. The train derailment also caused the adjacent road to be closed, and local law enforcement recommends the area is to be avoided as long as it takes to clean it all up. In the photos, damaged Jeeps and other trucks sit either on their wheels or shiny-side-down as the incident is being assessed. Available information says there were thankfully no personal injuries, but itÂ’s not likely any of these trucks will end up in customer hands, even with a significant discount. Pre-registration transport damage, significant or not, has often resulted in scrapping complete vehicles so that manufacturers can steer clear of liability issues. Hooniverse.com, which also reported on the incident, notes a couple of interesting things. Firstly, the upended Gladiator seems to have a pretty sturdy support structure for its glasshouse, thanks to its new rollbars. Another matter is that the GM trucks, also pictured, wear discreet and temporary transport steel wheels instead of fancier items, perhaps to deter thieves eager to grab a shiny set from trucks on their way to the dealer. Still, itÂ’s a shame these vehicles could never fulfill their hauling purposes in the hands of new owners. Perhaps the manufacturers can at least use the damage for data-gathering purposes.
