2022 GMC Sierra AT4X First Drive Review | Luxury off-roader

BORREGO SPRINGS, Calif. – What does the 2022 GMC Sierra AT4X have in common with the Aston Martin Vulcan, Mercedes-AMG GT, Camaro ZL1 and Ford GT? The answer: Multimatic DSSV spool-valve dampers. These dampers – or shock absorbers as theyÂ’re also called – are a lot like the adaptive dampers found in many sport and luxury vehicles. In a general sense, they allow drivers to select how soft or firm a ride they want, but the Multimatic dampers are quicker to respond and have additional benefits related to off-roading.  Off-roading is the main reason this new AT4X model has been added to the Sierra lineup this year, along with its elevated levels of luxury. ItÂ’s a big step up from the existing less-capable AT4 trim, which misses out on the DSSV dampers, electronically locking front and rear differentials, and 32-inch Goodyear Wrangler DuraTrac Mud-Terrain tires. The timing of this debut coincides with a significant overhaul for the entire 2022 Sierra lineup, including revised styling, a more muscular 2.7-liter turbo-four engine, and most notably, an interior overhaul that replaces this generationÂ’s dull and outdated dashboard with a fresh, modern and more competitive interpretation bolstered by a large 13.4-inch touchscreen powered by the Android Automotive OS. Upping the luxury further is a new, fully-loaded Denali Ultimate trim that includes the Super Cruise automated driving system, though our time in the revised 2022 Sierra was almost entirely in the AT4X. In addition to the off-road equipment and interior improvements listed above, the Sierra AT4X features the 420-horsepower 6.2-liter V8 as standard equipment, improved underbody skid plates, and a new Terrain drive mode. But thatÂ’s not all, because the AT4X is also differentiated by the X-less AT4 with a cabin thatÂ’s almost as extravagant as that luxurious Denali model, minus the availability of Super Cruise. Ventilated seats with massage functions, premium leather upholstery, wood trim and Bose audio are all standard. Altogether, this big truck could be the perfect way to get to your next glamping adventure. We had the opportunity to check out the AT4XÂ’s capabilities within the Anza-Borrego Desert State Park, a few hours east of San Diego. There, we encountered long stretches of dried riverbeds, narrow chokepoints as well as steep climbs and descents. After dropping pressures in the Goodyear mud-terrain tires to a flaccid 15 psi, we skimmed through the silted riverbeds with ease.

2023 GMC Sierra AT4X could swipe a few parts from the AT4X AEV

GM recently expanded its collaboration with American Expedition Vehicles beyond the Bison herd with the 2023 GMC Sierra AT4X AEV. This Jimmy takes matters further than the standard AT4X by increasing ground clearance, approach and departure angle, and breakover angle, improvements made possible by new stamped steel bumpers and a set of 33-inch mud-terrain tires wrapping 18-inch AEV Salta wheels. GM Authority says the AT4X AEV won't be the only Sierra to get special parts, crediting sources for the news that the standard 2023 Sierra AT4X will get some of the equipment from the special trim. According to the report, at some point for the coming model year, the off-road-focused Sierra will bolt on the AEV's stamped steel front and rear bumpers, stamped steel front skid plate, and 33-inch Goodyear mud terrains. If this is true, it's an intriguing move; the equipment list is nearly everything found on the proper AEV model. Going by that list, the only bits left off would be four additional skid plates, wheels, gloss black door handles, gloss black tailgate accent, and AEV logos. Judging from the GMC retail website, the grille that debuted on the AT4X AEV will also be on the standard AT4X.  GMC hasn't announced pricing for the 2023 range yet. The pickup will be carryover, but we would expect various well-known issues to increase the $78,300 price of the regular AT4X over the 2022 model. GMA believes "it's reasonable to assume" that a standard 2023 Sierra AT4X with some AEV parts would go up even more, whenever it hits the market — and this is on top of the Sierra's $1,500 price increase from making OnStar standard equipment. And after that, of course, the proper AT4X AEV would be more again.

NHTSA, IIHS, and 20 automakers to make auto braking standard by 2022

The National Highway Traffic Safety Administration, the Insurance Institute for Highway Safety and virtually every automaker in the US domestic market have announced a pact to make automatic emergency braking standard by 2022. Here's the full rundown of companies involved: BMW, Fiat Chrysler Automobiles, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Subaru, Tesla, Toyota, Volkswagen, and Volvo (not to mention the brands that fall under each automaker's respective umbrella). Like we reported yesterday, AEB will be as ubiquitous in the future as traction and stability control are today. But the thing to note here is that this is not a governmental mandate. It's truly an agreement between automakers and the government, a fact that NHTSA claims will lead to widespread adoption three years sooner than a formal rule. That fact in itself should prevent up to 28,000 crashes and 12,000 injuries. The agreement will come into effect in two waves. For the majority of vehicles on the road – those with gross vehicle weights below 8,500 pounds – AEB will need to be standard equipment by September 1, 2022. Vehicles between 8,501 and 10,000 pounds will have an extra three years to offer AEB. "It's an exciting time for vehicle safety. By proactively making emergency braking systems standard equipment on their vehicles, these 20 automakers will help prevent thousands of crashes and save lives," said Secretary of Transportation Anthony Foxx said in an official statement. "It's a win for safety and a win for consumers." Read on for the official press release from NHTSA.
