2019 GMC Sierra AT4 First Drive Review | Off-road overkill

The road ahead is dirt with a rut here and a rock there. Brush keeps a respectable distance on the right side, the edge on the left gradually falls away into the valley below. The grade is nothing your treadmill couldn't duplicate and traction is pretty good. Honestly, a couple in their Subaru Crosstrek could pop up here for a picnic. The 2019 GMC Sierra AT4 we're driving is therefore complete overkill. But at least it looks the part as it trudges up this uncharacteristically verdant mountain with San Diego in the distance to the north and Mexico to the south. Its special, dechromed AT4 grille has a purposeful appearance, but tastefully lacks the show-off machismo of Ford and Ram's off-roading models. The red tow hooks are a nice touch and the dark-accented 20-inch wheels wrapped in all-terrain rubber are just the right size beneath a suspension that is raised an extra 2 inches from every other Sierra. That would be one of the key elements that differentiates the AT4 as the Sierra's off-roading model – GMC's answer to the Chevy Silverado's Trail Boss trims. In fact, their mechanical enhancements are identical. Besides the 2-inch lift, the suspension features off-road-tuned Rancho monotube shocks. There's also a locking rear differential, a two-speed transfer case, skid plates and those tow hooks. The 5.3-liter V8 with Dynamic Fuel Management is similarly standard, but unlike the Silverado Trail Boss, the Sierra AT4 offers the 6.2-liter V8 good for 420 horsepower and 460 pound-feet of torque as a roughly $2,500 option. That's the engine we have and it delivers the expected punch, complete with a satisfyingly snarling exhaust note. However, as observed in back-to-back drives with these two available engines during the Silverado launch, the 6.2 certainly isn't necessary. The 5.3-liter is seriously capable and the bigger engine is largely for those who want to have the biggest number possible emblazoned on the fender. It's overkill, which in this particular environment, is fitting. Besides the available engine upgrade, the AT4 also goes beyond its Trail Boss counterpart by dipping into the Sierra Denali's tool box. Its MultiPro tailgate is standard equipment, allowing for six different configurations, the most notable of which include a means of more easily reaching into the bed and a drop-down step that eases entry into the bed. GMC's considerable touting of that last element is rife with hypocrisy given GM advertisements that mocked Ford's similar feature.

GMC's electric, 1,000-horsepower Hummer SUV makes a surprise appearance

We knew the GMC Hummer pickup would spawn an SUV, but we didn't expect to see it so soon. It quietly appeared in a marketing presentation about electric cars that General Motors streamed online in November 2020. The camera never focused on the SUV, there was always an executive sitting in front of it, but we see enough to tell it's closely related to its pickup sibling. Both battery-powered off-roaders are nearly identical from the tip of the front bumper to the edge of the rear doors. The SUV's overhang is a little bit shorter than the pickup's, though there's presumably space for a third row of seats. Its rear end doesn't appear in the presentation. Nothing suggests GMC made major powertrain changes to the SUV, so it's likely identical to the truck underneath the sheetmetal. Range-topping models will receive three motors zapped into motion by a 24-module Ultium battery pack. Motorists will have 1,000 horsepower and approximately 350 miles of driving range to play with. GMC plans to start building the Hummer pickup in late 2021, and the SUV might not enter production until early 2022. We expect pricing will initially start above $100,000, but more affordable variants will gradually join the lineup during the first half of the 2020s. When it lands, the off-roader will compete directly against the Rivian R1S. General Motors will invest $27 billion into electric and autonomous cars by 2023. Its portfolio of EVs will also include a Silverado-sized pickup, a crossover based on the Bolt, and a high-end Cadillac crossover named Lyriq. "We want to be number one in EVs in North America," affirmed company boss Mary Barra.

2024 GMC Acadia gets bigger, goes entirely turbocharged

For an entire generation now, the GMC Acadia, the brand's largest unibody SUV, has sat in an unusual zone in between the typical midsize two-row and large three-row segments. But the completely redesigned 2024 Acadia is stepping confidently into the latter camp, growing to roughly match its cousin, the also fully redesigned 2024 Chevy Traverse. And adding to its greater size and performance, the Acadia brings unique exterior and interior design. The size increase is impressive. The wheelbase has grown 10.6 inches, overall length by 8.4, and overall height by 3.2. GMC claims this has increased cargo space by 80% and second-row seat room by 27%. These changes all make it about the same size as the Chevy, too, instead of a smaller option.  This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. That doesn't mean the two look the same, though. The front fascia clearly borrows heavily from the GMC Sierra 1500 with a tall grille and C-bracket headlights. The flanks really depart from the aggressive shape of the Traverse. It also skips the fat C-pillar. GMC designers noted they specifically worked to reduce the size of that pillar, in part to improve visibility for third-row passengers. Conversely, the D-pillar is relatively large and is finished in body color to reveal it. But to keep it from looking overly large, there's a black plastic panel that helps give the rear window a bit of a wraparound effect. The taillights also have a gloss black panel to blend them into the rear window area and reduce the visual mass of the hatchback. The interior is the biggest differentiator between the Traverse and Acadia, though. The entire dashboard is unique to the Acadia. The 11-inch instrument display sits under a cowl that extends horizontally to meet the unique vertical 15-inch infotainment screen. That screen overlaps a squared-off, horizontal dash design, and it's flanked by vertical air vents. The Acadia picks up a column-mounted shifter, too, freeing up space for storage in the center console. There are practically no parts directly pulled from other GM products. And unlike GM's upcoming EVs, the Acadia will have Apple CarPlay and Android Auto functionality. Individual Acadia models even have unique features. The luxury Denali trim and off-road focused AT4 trim both return. The AT4 stands out the most with an extra inch of ground clearance in part from the all-terrain tires on 18-inch wheels.
