2017 GMC Sierra 2500HD All Terrain X eyes Ram Power Wagon

If where you're going, you don't need roads, you're spoiled for choice by American automakers. Ford has the F-150 Raptor, Jeep the iconic Wrangler, and Ram offers Power Wagon. And that's just the tip of the factory off-road iceberg. General Motors is getting in on the off-roading action with the Canyon and Sierra 1500 All Terrain X. Now, the automaker is adding another notch on its belt with the Sierra 2500HD All Terrain X. On the outside, GMC continues to the all-black trend as the rest of its off-roading-oriented lineup, which includes 18-inch aluminum wheels finished in black, a bespoke grille surround, black sport bar that's mounted in the truck's bed, and four-inch side steps in black. The All Terrain X will only be offered in two colors – Black Onyx and Summer White. Those looking for more off-roading capabilities and tack the Z71 off-road suspension package as an option on the All Terrain X, adding performance Rancho shocks, Hill Descent Control, and a shield for the underbody transfer case. Two engine choices lie under this crew cab pickup's massive hood - the 6.0-liter gas V8 or the all-new Duramax 6.6-liter turbo-diesel V8. The gasoline-powered V8 continues to make 360 horsepower and 380 pound-feet of torque, while the new Duramax turbo-diesel generates 445 horsepower and 910 pound-feet of torque. While the All Terrain X may not have the same murderous look as the Ram Power Wagon, it makes off-roading a luxurious affair. And it's blacked out. The 2500HD power wagon will be on sale early next year, with a pricing announcement coming sometime in the next few months.

GMC Hummer EV recalled over improperly sealed battery pack

Over 700 units of the GMC Hummer EV built during the 2022 and 2023 model years will be recalled due to an improperly sealed battery pack that lets water in. The firm issued a stop-delivery order at the same time as the recall, and it hasn't found how to fix the problem yet. Assigned recall number 22V-771 by the National Highway Traffic Safety Administration (NHTSA), the campaign includes 735 examples of the Hummer EV and 89 units of the BrightDrop Zevo 600 van. These two vehicles are pegged on opposite ends of the automotive spectrum, but they're affected by the same problem: "the high-voltage battery pack enclosure in some of these vehicles may not have been properly sealed," GMC notes, adding that "flanges on the battery pack enclosure may not have been properly primed or electrocoated." Water can wreak havoc in a high-voltage battery pack. GMC told NHTSA that it has found three EVs with this problem: an internal test vehicle that lost power while driving and two customer-owned vehicles that wouldn't start. As of writing, the firm is not aware of any accidents, injuries, or fires related to the issue, and GMC estimates that only about 1% of the recalled EVs are affected. GMC began notifying dealers of the recall in October 2022, and it plans to start reaching out to owners on November 28, 2022. However, a fix hasn't been found yet. In the meantime, the company issued a stop-delivery order and asked dealers not to attempt their own repairs. This isn't the Hummer EV's first run-in with water-related problems. In August 2022, General Motors voluntarily recalled 424 units of the Hummer EV and the Zevo 600 van due to a high-voltage connector that can prematurely corrode. The problem also let water leak into the battery pack, though it sounds like fixing it was reasonably straight-forward and involved applying sealant to the connector.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.
