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.

2020 Chevy Trax spied sporting design cues from the new Blazer

We saw spy shots in August for what we thought was either a redesigned Chevrolet Trax or new GMC subcompact crossover. At the time we were leaning Chevy. But after this latest batch of spy shots taken near GM's proving grounds, we're now thinking this one is the Trax replacement and the other one was a GMC. For one, the thin row of LEDs looks remarkably similar to the 2019 Chevy Blazer's LED strip. The additional light slightly below that is similar to the Blazer as well, leading us to believe that the next Trax will have a Blazer-esque front end. At first glance, this vehicle looks slightly larger than today's Trax with a much brawnier shape than the current blob-like design. The rear roof cladding could be hiding the same sloped rear window with spoiler hangover we see on the Blazer. Circling back to the other small GM crossover we caught testing, this one doesn't have those Blazer elements. The curved windshield and sloping roof are like those of the GMC Terrain, as are the horizontal grille bars. By contrast, the above car has a straighter windshield and a roof shaped more like the Blazer. One element that does seem to diverge from the new Blazer are the taillights, but they don't exactly look production-ready anyway. If we're right about this being the next Trax (and we're pretty sure we are) then this looks to be a more distinctive vehicle than what it will replace. The mirrors have left their awkward spot on the doors, and it's shaping up to be a much sportier looking crossover as a whole. This vehicle will most likely end up being a 2020 model year car, and if so, we would expect to see undisguised photos of both it and the assumed GMC version next year.

2021 Chevy Silverado, GMC Sierra fuel economy to go down due to global chip shortage

Production of the 2021 Chevy Silverado and 2021 GMC Sierra is continuing, but the global semiconductor chip shortage is resulting in a mid-year change. Or rather, an omission.  Basically, the availability of cylinder deactivation for the 5.3-liter V8 will be significantly reduced, resulting in a reduction of 1 mpg combined for affected models. This applies whether that engine has the six- or eight-speed automatic, as well as to both the regular Active Fuel Management and the more advanced Dynamic Fuel Management cylinder deactivation systems. DFM does remain with the pairing of 5.3-liter V8 and 10-speed automatic that comes standard on the LT Trail Boss and High Country. "Due to the micro controller shortage, the components that control AFM/DFM in the engine control module (ECM) have been removed," GM spokesperson Michelle Malcho told Autoblog. She also indicated that the engines will still have the AFM/DFM hardware in place, but that GM will not allow activation of the systems in the future with an ECM change.  Malcho also confirmed to Autoblog that the Silverado and Sierra's other engines will continue to have AFM and DFM, including the 2.7-liter turbo inline-four, 4.3-liter V6 and 6.2-liter V8. In an earlier statement to Reuters, she declined to say the volume of vehicles affected. "By taking this measure, we are better able to meet the strong customer and dealer demand for our full-size trucks as the industry continues to rebound and strengthen," Malcho wrote Reuters in an email. The change runs through the 2021 model year, she said. Malcho told Reuters it would not have a major impact on the Detroit automaker's U.S. corporate average fuel economy (CAFE) numbers. "We routinely monitor our fleet for compliance in the U.S. and Canada, and we balance our portfolio in a way that enables us to manage unforeseeable circumstances like this without compromising our overall (greenhouse gas) and fuel economy compliance," she said. GM's fleetwide fuel economy in the 2018 model year was 22.5 miles per gallon and was projected to rise to 22.8 mpg for 2019, according to a report by the Environmental Protection Agency. To meet federal CAFE requirements, automakers like GM often use credits from either earlier years where they faced less stringent rules and performed better than the requirements or buy credits from other automakers. GM said last month the chip shortage could shave up to $2 billion from this year's earnings.
