2024 GMC Sierra HD AT4X and Extreme AEV muscle their way into the lineup

The new AT4X variant of GMC's 2024 Sierra HD pickup series officially joins the stable this week, giving pickup truck box-checkers yet another off-road trim to chase. Well, two trims, technically, as GMC took the opportunity to announce that the AT4X will also be offered with an upfit package from American Expedition Vehicles, appropriately named the Extreme AEV Edition that takes its cues from the same package offered on the Sierra 1500 AT4X. And with its introduction, the 2024 GMC Sierra HD lineup is now complete.  GMC's Sierra AT4X models mirror the ZR2 packages offered on the updated Chevrolet Silverado. If you paid any attention at all to the Silverado HD ZR2's introduction earlier this month, you'll be familiar with the formula. Key upgrades include a 1.5-inch factory lift, standard electronic locking rear differential, Multimatic DSSV shocks and 35-inch Goodyear Territory all-terrain tires. It also gets beefier skid plates —  both the steel protecting the transfer case and the aluminum piece up front. With the updated 6.6-liter Duramax diesel, GMC says it'll tow up to 18,500 pounds.  "GMCÂ’s AT4X trim, which will be available across the entire GMC truck lineup, offers customers more premium and capable choices when it comes to ‘do-it-allÂ’ capabilities," said GMC VP Duncan Aldred. "Each model delivers unique strengths, with the all-new Sierra HD AT4X taking it to the max, enabling you to go virtually anywhere, with the towing power to bring your recreational toys, gear or camper along for the journey." And by "do it all," he means all the luxury stuff too, judging by the Obsidian Rush interior, which GMC says includes massaging leather front seats and real ash wood trim. The better from which to feel the shove of the AT4's two available 6.6-liter engines, one a gasoline-burner rated at 401 horsepower and 464 pound-feet of torque, the other a Duramax turbodiesel making 470 horsepower and 975 pound-feet of torque. You'll need the latter if you want to hit GMC's advertised towing capacity.  And don't forget the Extreme AEV Edition, which will surely come with a Denali-rivaling (and still TBA) price tag. The stamped steel bumpers stand out right away, as do the integrated front recovery points and winch mount. The package also adds more skid plates protecting the steering gear and transfer case. Its 18-inch "Salta" wheels are also unique.  GMC says it will be cranking out 2024 Sierra HD AT4Xs and Extreme AEV Editions by the third quarter.

2022 GMC Sierra Preview | GM's 'premium truck' is actually now premium

Pros: Quiet and torque-rich Duramax diesel; big touchscreen on most trims; great trailering tech; versatile MultiPro tailgate Cons: Worse ride than most rivals; AT4X priced like a Raptor but doesn't go like a Raptor The 2022 GMC Sierra 1500 is GM’s upmarket half-ton pickup, with a supposed emphasis placed on interior quality and materials rather than bare-bones durability. Supposedly, at least. In reality, the most recent generation hardly lived up to that promise as it showed few upgrades over its Chevy Silverado sibling, which itself possessed a ho-hum, not-really-trying interior clearly overshadowed by Ram and Ford that at least match it in most other respects. It was particularly noticeable when comparing top trim levels. GMC's supposedly premium entry, and especially the Denali, just didn't cut it. That changes in a huge way for 2022. First, thereÂ’s not just one new and massively improved interior, there are two. The SLE, Elevation and SLT once again share their interior design with the Silverado, but that includes a more visually appealing design, better materials, smarter storage and a significant technology upgrade thanks to the standard 13.4-inch touchscreen running the user-friendly Android Automotive OS. The AT4 and Denali trim levels, including the new AT4X and Denali Ultimate, step things up even further with a different dash design and upgraded interior materials. The Ultimate definitely lives up to its name with a characterful and, yes, premium vibe that stands tall against the best of Ford and Ram. Other welcome updates include the option of Super Cruise on top trim levels and a massively more powerful base turbo four-cylinder engine (it produces more torque than the 5.3-liter V8!). Effectively, the 2022 GMC Sierra is now the truck it shouldÂ’ve been since the beginning of this current generation and definitely worth a look – especially if youÂ’re in the market for a premium truck. Now, a bit of housekeeping. While the massively updated model shown here is officially the 2022 GMC Sierra, thereÂ’s a chance you could come across something called the "2022 Sierra Limited.” That was just last year's truck with the 2022 model year stapled to it. There are many reasons for this, but suffice it to say, if you see a Â’22 Sierra Denali with the ugly robot-face dashboard (below right), youÂ’re looking at a Limited. Also, the availability of Super Cruise and other features have been hampered by supply shortages.

GM delays 3.0-liter Duramax diesel in Silverado and Sierra pickups

Stricter testing protocols around the world are making it harder for automakers to predict launch timelines. GM is the latest to get caught in emissions nettles, the Detroit carmaker forced to delay the launch of its new Duramax 3.0-liter inline-six diesel for the Chevrolet Silverado 1500 and GMC Sierra 1500. That's what company reps told dealers in a memo seen by Automotive News this week. Dealers and buyers had been promised the Flint, Mich.-built oil-burner in early 2019, but AN wrote that the EPA certification hiccup has turned into a "slight delay." A GM spokesman told Motor1, "[We] did not attribute [the delay] to a single entity, as the truth is this is a collaborative effort between GM and several government entities. We will make the 2020MY Duramax available for dealers orders soon, and expect to deliver the first trucks to customers soon after emissions testing is complete." We know the new 3.0-liter Duramax diesel has 277 horsepower and 460 pound-feet of torque, outdoing Ford's 3.0-liter PowerStroke diesel by 27 hp and 20 lb-ft. But without final EPA paperwork, GM can't release the numbers that will show how the two engines stack up when considering fuel economy and tow ratings. The certification process has been sticky for a few other makers of late, especially since the Volkswagen Group situation in 2015. BMW had to delay the launch of four diesel models in 2016 over EPA testing. The new Ram 1500 dribbled out in a trickle last year for reasons thought to deal with EPA testing, coming as it did a year after the EPA investigated Ram's EcoDiesel engines in 2017 and 2018. More recently, WLTP testing in Europe caught out just about every automaker over there. Since we're almost halfway through 2019, the delay until the 2020 model year is only a few months. Still, GM told dealers to cancel any orders for the engine for this model year. Dealers will need to resubmit the orders once opening begins, but GM hasn't said when production will begin other than "soon." The company said that it will offer 2020-model-year replacement vehicles to customers and dealers. If prices hold into the next model year, the 2020 Silverado 1500 and Sierra 1500 with the inline-six diesel will come at a $3,890 premium over the 2.7-liter turbo four-cylinder, and a $2,495 premium over the 5.3-liter V8.
