2022 GMC Hummer EV dimensions, clearances and off-road features explained

There are two things that almost everyone immediately thinks of when they hear the word "Hummer." And they are size and off-road capability. Looking at the numbers on the 2022 GMC Hummer EV, it seems the electric pickup has literal truck loads of each. One of the most prodigious numbers is the truck's width. See those clearance marker lights on the roof? They aren't just there for style, they're required by law due its width. At 86.7 inches, it's just a bit wider than a Ford F-150 Raptor, which is itself 6.4 inches wider than a comparable F-150. The Hummer is also 5.5 inches wider than a GMC Sierra. Length is more reasonable at 216.8 inches, which is much less than a full-size crew cab pickup (a Sierra 1500 is 231.7 inches with its 5-foot-8-inch box or 241.2 with the 6-foot-6 one). It's even 3 inches less than the Raptor SuperCab and only 4.4 inches longer than a GMC Canyon with the standard 5-foot-2-inch box. In other words, the Hummer EV is roughly as long as a midsize pickup but is wider than a heavy-duty one.  What does that mean for the cabin? With 38.9 inches of rear legroom, it falls well short of a Sierra Crew Cab's 43.4, but it's important to remember that crew cab pickups have an overkill amount of limo-like legroom. The Hummer's amount is still 3.7 inches longer than a Sierra Double Cab and 3.1 inches longer than a Canyon Crew Cab. Headroom, which was rather pathetic in the old Hummer H2, is 38.6 inches in the back seat – less than both its GMC truck siblings, but not by much. In other words, there should be plenty of space back there. Note that GMC didn't indicate bed length, frunk volume, or importantly, curb weight. We will update this should we find out answers to any of those.  Although it's big, the Hummer has plenty of features to make it nimble off road, both traditional and high-tech. One of the primary features is the height-adjustable air suspension, which offers 13 inches of travel and automatically adjusts damping for driving conditions. It has three main levels, a lowered setting for Aero Mode that helps with improving highway energy use, a default height for the normal driving modes, and a higher setting for the off-road Terrain Mode.

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.

GM recalls 330,000 fullsize trucks for airbag replacement

General Motors has announced a recall of 330,198 fullsize pickups in the US in the aftermath of the announcement made on May 19 that doubled the number of vehicles being called in to replace Takata's defective airbag inflators. That announcement expanded the nationwide recall to an estimated 33.8 million vehicles in the US. Heavy Duty versions of the 2007 and 2008 Chevrolet Silverado and GMC Sierra are included in GM's move, for the purpose of replacing the passenger airbag inflators. The announcement made by the National Highway Traffic Safety Association cited long-term exposure to moisture as a possible cause of the inflator issues. GM says it isn't aware of any problems with the recalled pickups due to moisture, nor has it had any reports of crashes, injuries, or fatalities, and has not received any complaints. GM will notify owners, who can then take their trucks to the dealers to have them repaired free of charge. You'll find a statement from GM and the recall notice from NHTSA below.
