2021 GMC Sierra 1500 Review | More towing, same truck

The 2021 GMC Sierra 1500 and the Chevrolet Silverado 1500 are close siblings, and they’re getting closer every year. One of the SierraÂ’s previous standout features, the Multi-Pro tailgate, can now be found on the Silverado for 2021, providing even fewer reasons to choose the GMC instead of the Chevy. Really, if youÂ’re looking at the more modest SLE and SLT models, the choice between the two largely depends on styling preference. The Sierra Denali is a slightly different story, as its available adaptive suspension is exclusive to GMC and notably improves both the ride and handling.  Of course, it still can't match the Ram 1500 in either regard, plus the Denali cabin continues to be a rather half-hearted attempt at luxury. Especially considering the genuinely high-lux offerings of Ram and Ford. The gap isn't so huge between the Sierra's lower trim levels and its non-Chevy competitors, but the cabin's design, quality and functionality still leave something to be desired. True, that often isn't a priority for truck buyers, but the Sierra isn't superior in enough other ways to balance it out. It's a capable truck with a compelling variety of powertrains, but it generally just doesn't go that extra mile beyond the competition as well as its Silverado sibling. What's new for 2021? Changes for 2021 are mostly equipment-related, but there were some vital towing and pricing changes made for the new year, too. All 2021 Sierra 1500s come with a suite of new towing tech detailed here. New technologies include a trailer length indicator, jack-knife alert, trailer backup guidelines, and camera enhancements that include a rear side view and cargo bed view. GMC expanded availability of the Multi-Pro tailgate, now allowing folks who opt for the lower SLE and Elevation trims to option it. The AT4 adds new Goodyear Wrangler Territory all-terrain tires and an off-road high-clearance step. Diesel buyers will be delighted to hear that GMC has lowered the price by $1,500 to $995, and raised the trailering capacity by 1,900 pounds to a more competitive 9,300. Maximum towing for the 2.7-liter turbo-four-cylinder is also up by 2,300 pounds to 9,200 pounds. GMC says the increase for the diesel is due to “better-than-expected rear axle durability,” and the four-cylinder is up because GM found the engine possesses “better-than-expected cooling performance.” What's the interior and in-car technology like?

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.

2021 GMC Canyon gets AT4 trim and a 'more upmarket' Denali

The AT4 train continues at GMC, with the 2021 Canyon AT4 climbing to altitude in Vail, Colorado, to announce its arrival. The off-road package, teased during the Sierra HD launch last year and already rolled out on the Sierra and Acadia, replaces the Canyon All Terrain trim. The rectangular grille goes away, the new rig picking up a larger, Sierra-like grille with a dark chrome surround and vertically-oriented fog lights. And because nothing says off-road badass like red recovery hooks, of course there's a pair peeking out from under the tweaked lower bumper. Otherwise, all the All Terrain kit carries over, like the tuned suspension with Advanced Hill Descent Control, transfer case skid plate, automatic locking rear differential, and 31-inch Goodyear Wrangler DuraTrac® tires on 17-inch aluminum wheels. Inside, the headrests are embroidered with AT4 logos, and Kalahari stitching is exclusive to this trim. GMC also announced a more polished Denali trim, without providing any photos. The coming pickup adopts a grille with a "more sculpted and layered pattern," plus five-inch chrome assist steps, and 20-inch Diamond Cut aluminum wheels that we'll assume come in a different pattern than the current 20-inch Diamond Cut aluminum wheels. The cabin goes upscale with open-pore ash wood trim and aluminum trim, a new Cocoa/Dark Atmosphere color theme, and unique stitching. Both the AT4 and Denali offer the same two engine choices. There's either the 3.6-liter V6 throwing out 308 horsepower and 275 pound-feet of torque, shifting through an eight-speed automatic, or the 2.8-liter Duramax diesel producing 181 hp and 369 lb-ft, shifting through a six-speed auto. The 2021 trucks will be available later this year, pricing to be announced closer to the on-sale date. The 2020 Canyon All Terrain starts at $37,695, the 2020 Canyon Denali starts at $41,595.
