GMC and AEV reveal Sierra Grande upfit SEMA concept

If there was any question as to whether GMC was dedicating resources to its off-road models, it was dismissed the instant American Expedition Vehicles entered the conversation. The two have already partnered to produce a GMC-branded alternative to the Chevrolet Colorado ZR2 Bison. The 2024 GMC Canyon AT4X AEV Edition is midsize pickup perfection, but the collaboration is far from over. With GMC now pushing the AT4X package on its heavy-duty pickups, AEV is looking for ways to explore the space.  "The Sierra Grande Concept represents AEV’s creative vision of how the company would further elevate the adventure-ready foundation of the GMC Sierra HD AT4X into a legendary overlanding rig," AEV said in its announcement The Sierra Grande is all Sierra HD AT4X underneath. The steering knuckles, control arms, rear suspension and butter-smooth DSSV dampers are all lifted directly from the production truck. This SEMA-bound concept is the quintessential upfit smorgasbord, boasting everything from add-on lighting to upgraded underbody protection. There are even two winches — one for the front and one for the back. If you ask us, they should have gone ahead and put one on each side too.  The snorkel pairs nicely with the 40-inch BF Goodrich tires, and the onboard air system guarantees you're never in a pickle when you hit pavement to head home. The bed is aluminum, but the skid plates are stamped steel (as is the brush guard). The front winch is rated for 12,500 pounds; the rear for "just" 9,500.  Unlike the Canyon AT4X AEV Edition, the Sierra Grande is merely an exercise — for now, anyway. We suspect that GMC has plenty more in store for its off-road trucks.  Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

GM looks to combat high theft rates on SUVs with added tech

The Cadillac Escalade has been at or near the top of most-stolen and insurance-loss lists for more than seven years, until it dropped to number six earlier this year. In 2011 it was fitted with a host of new security features to address its easy-to-override features and that has brought the number of thefts down, but when eight of the ten most stolen rides are large SUVs from General Motors, no one will argue that something else needs to be done.
Thus, GM has fitted this same theft-deterring tech to the 2015 Suburban, Tahoe and Yukon. The Suburban and Tahoe will get the steering lock that the Escalade and Yukon already get, plus bolted-down third-row seats to deter thefts like this, stronger door lock cylinders and shields, and side-cut keys to inhibit picking.
Additional security measures in a Theft Protection Package can be purchased for $395, consisting of sensors on the greenhouse glass and interior, an incline/tilt sensor and added "key control systems" to make it more difficult for the men in black balaclavas to steal what you bought.

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.
