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 Sierra EV Denali Edition 1 teased before tonight's debut

GMC says its Sierra EV Denali Edition 1 battery-electric pickup is "Built to tower above everything you thought an electric truck could be. That’s why itÂ’s the only EV that deserves the name Denali." We will know what the marketing speak means tomorrow (Thursday), when GM's third electric pickup in a year debuts at 5 p.m. Eastern. GMC teased the face of the Ultium-powered Sierra Denali nearly a year ago with an animated rendering. This second teaser on the eve of the debut gives us a better feel for what to expect. The front fascia advertises the product with illuminated GMC lettering at the center of a grille panel defined by an illuminated border. Upside down L-shaped LED lights frame three LED charging status bars. Below those at the bumper edges are what look like four fog lights, two round units above two squared oval units. In back, a glimpse of taillight reminds one of the Hummer EV's spendy rear lights, a Denali badge informing tailgaters what kind of truck they're following. A panoramic glass panel takes up just about the entire roof, save for some sheetmetal at the back where the shark fin antenna rests. Under that roof, one of the seating options will be a ventilated, quilted fabric with "Denali" embroidered in the headrest.  All the other intel must wait another 24 hours. This truck's Chevrolet Silverado EV sibling has been pitched as pricing between $40,000 and $105,000. We've been told the Sierra EV will only come in Denali trim, so expect the feature set and pricing to align more with the Hummer EV, from close to $100,000 once all trims are rolled out to sums well over $100,000. The furnishings could set a new benchmark in glitz for GMC, brand VP Duncan Aldred saying, "We now have an opportunity to evolve SierraÂ’s capabilities and technologies, as afforded by transitioning to an all-electric propulsion while also elevating the luxurious design and comfort associated with Denali." The playbook established so far leads us to believe the Ultium platform will provide a 200-kWh battery and an estimated range of 400 miles, and an output of something like the 664 horsepower and 780 pound-feet of torque in the top Silverado EV trim. Or this limited Edition 1 trim could split the power gap between the Silverado EV and the 1,000-hp Hummer EV.  Reservations open after the debut.

GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.
