2024 GMC Hummer EV SUV First Drive Review: Still impressive, even out of its element

SAN FRANCISCO – Our first experience with the GMC Hummer EV in any form was spent in an environment clearly ideal for such a vehicle. That first drive of the production-ready truck was in Arizona, a place with large, open freeways and rocky, desert terrain. Notably, they were areas that could showcase the Hummer's strengths: enormous power and acceleration, a lack of trees or narrow lanes to hinder its size, and sufficiently rocky terrain to demonstrate its remarkable off-road abilities. So it was particularly strange that the media's first experience with the Hummer EV SUV would involve the tight streets and twisty mountain passes of San Francisco and Napa Valley, locations that certainly would seem to put the Hummer on the back tire. In some ways they certainly did, but at the same time, they revealed the Hummer is surprisingly capable out of its element, and maybe even a good fit for the area. The start of our driving time involved leaving downtown San Francisco and heading up Highway 29 to Napa where GM had set up a number of demonstrations like those at the truck first drive, and where our winery hotel was. In the birthplace of Tesla, where Models of all letters and number are ubiquitous, the monster black Hummer definitely stood out. And not just for its sheer size: it is the technological flagship of General Motors, perhaps the most traditional of American car manufacturers. On the other hand, the locale also felt appropriate given that flagship status, from its flashy instrument and infotainment displays, to its acrobatic suspension and steering systems. This is as good a time as any to go over what makes the Hummer EV SUV different from the truck. Obviously it has a solid roof over a cargo area instead of an open bed. It's also the smaller of the two giants: total length is 20 inches shorter (excluding the spare tire) and the wheelbase is 8 inches shorter. That pays a few dividends in maneuverability both on and off road. The turning circle of the SUV is 1.7 feet smaller, at 35.4 feet, which is almost 3 feet tighter than that of the Chevy Bolt EUV. The breakover angle is also improved by 10.6 degrees (49 at max ride height) and the departure angled by 2.2 degrees (34.4 at max ride height). Though the bed is gone, the interior cargo space is certainly spacious, with maximum capacity of 81.8 cubic feet with the rear seats folded perfectly flat into the admittedly high load floor.

GM delaying additional Silverado EV and Sierra EV production to Q4 2025

This looks like more "Gotcha!" news about storms in the EV sector, but the word "additional" is key here. The Detroit News reported today that GM is pushing delaying production of the Chevrolet Silverado EV and GMC Sierra EV pickups at the Orion Assembly Plant to late 2025, about a year behind expectations. The Silverado EV Work Truck is already in production at GM's Factory Zero in Detroit, which won't change. Retail versions of the Silverado EV are still planned for production at Factory Zero before the end of this year, and the Sierra EV is expected to enter production at Factory Zero early next year. This new plan simply means GM won't add more production of those electric trucks at Orion.  GM builds the Chevrolet Bolt at Orion right now, assembly of that groundbreaking car to end this year. GM's original idea was to spend $4 billion to convert Orion to EV pickup production in time to get its two giant profit makers rolling down lines in early 2025. The move to late 2025 could mean the plant is out of commission for about two years. The facility's 1,261 employees are being offered spots in other plants, including Factory Zero.  The automaker gave several reasons for the move, a spokesperson telling The Detroit News the company wants "to better manage capital investment while aligning with evolving EV demand," and telling the Detroit Free Press, "We're looking at EV demand and the trendline for EVs is stabilizing. ... It is not rising as fast as originally forecasted." On top of that, engineers "have identified engineering improvements that we will implement to increase the profitability of our products." The spokesperson also made it clear that the delay has nothing to do with the UAW strike, now in its 32nd day.  Factory Zero's working up to a near-term production capacity of about 600,000 units annually, GM saying it wanted to get capacity to 1 million EVs annually by the end of 2025. At the moment, the site builds the Silverado EV Work Truck, the GMC Hummer EV pickup and SUV, and the Cruise Origin shuttles — not the Bolt taxis, the autonomous pods. The Detroit News reported GM sold 18 Silverado EV Work Trucks in Q3 this year, GM Authority says GMC Hummer EV production has ramped up to about 3,000 units per month, and Cruise Origin is still waiting on approval from the National Highway Safety Traffic Administration to mass-produce the autonomous shuttles because the shuttles need an exemption for not having steering wheels.

GMC Sierra AT4X reportedly on the way, nameplate could be GMC's ZR2

In 2016, GM filed an application with Mexico's Institute of Industrial Property to reserve the name AT4X, and in 2019, the automaker made the same request to the U.S. Patent and Trademark Office. Seeing that GMC's current AT4 trim replaces the former All Terrain trim used on the last-gen Sierra pickup, there have been suspicions ever since those trademark filings that GM would use the AT4X name to replace GMC's former All Terrain X trim. GM Authority reports that this is precisely what's going to happen, citing "sources familiar with the matter." The outlet even gleaned an equipment group number: 4SG for AT4X, whereas AT4 is equipment group 4SB.  The surmise is that GMC is again developing its versions of Chevrolet's dirt-clobbering pickups that wear the ZR2 name. Spy shooters caught the GMC Canyon earlier this month trotting around on Multimatic's DSSV dampers and a set of 33-inch tires like its Colorado ZR2 sibling. The Canyon already offers an AT4 trim, it's thought this beefier setup will roll into the lineup as an AT4X.  Stepping up to the half-ton league, at the end of last month Chevy released a teaser for the Silverado ZR2, which had been caught in prototype guise (pictured at top) around Detroit on at least two occasions. We've mused that the production Silverado ZR2 could take some hardcore off-roader cues from the factory-upgraded Silverado ZR2 race truck like a lifted stance, long-travel front suspension, four-leaf springs instead of three-leaf, electronic locking front and rear differentials, and a wider track. One of the production prototypes was caught on 33-inch tires, but we wouldn't be shocked to see 35-inchers on the spec sheet. That size would match the race truck and the rubber fitted to the cross-town rivals Ford Raptor and Ram 1500 TRX. A GMC Sierra AT4X would be the plusher, pricier, chrome-ier version of the ZR2. The aforementioned Multimatic shocks could also be on the docket. We'd expect the GMC Sierra AT4X to bow with the heavily updated 2022 pickup, whenever that arrives. Events around the world of late delayed the pickup, its launch now thought to happen late next year or in early 2023. Related Video:
