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.

2016 GMC Terrain refresh revealed

Posting its best-ever sales year in 2014, the GMC Terrain is hauling in sales, conquest buyers, and profits for the brand. GMC wants that to continue with its refresh for the 2016 model year, which sees the underlying formula left untouched under a raft of cosmetic and trim changes. There will be four trim levels: SL, SLE (SLE-1 and SLE-2), SLT, and Denali. They all get a front fascia with a lot more character, sculpted with chrome-outlined, C-shaped ornamentation, and all but the base SL version feature chrome accents on the grille. Flanking that, the headlights get new LED DRL signatures and the hood gets a power dome. The Denali gets new 19-inch alloys, models below it get new 18-inch wheel designs, and the sheetmetal color palette expands with the addition of White Frost Tricoat and Crimson Red Tintcoat. Beyond a revised center console, a mix of cabin offerings spice up the various trims. Premium cloth is the go-to for the SL and SLE, "Saddle Up" leather is an option on the SLT as well as an eight-way passenger seat, and a two-tone, dual-material Light Titanium and Jet Black interior is possible inside the Denali. Assistance features migrate down, with Side Blind Zone Alert and Rear Cross Traffic Alert available on the Terrain SLE and SLT for the first time. Engine choices remain the 182-horsepower Ecotec 2.4-liter inline-four, and the 272-hp 3.6-liter V6. The press release below has more details, and we'll have more on it live from the show floor. GMC Introduces 2016 Terrain New appearance, features build on success in growing compact SUV segment NEW YORK, March 31, 2015 – Distinguished by a new, more contemporary front-end appearance, the 2016 GMC Terrain and Terrain Denali were introduced today, ahead of their public debut at the New York International Auto Show. The 2016 Terrain lineup features new front and rear fascias, new grille designs, a power dome hood, light-emitting diode (LED) daytime running lamps and additional updates. Side Blind Zone Alert and Rear Cross Traffic Alert are offered on SLE and SLT models for the first time. "Terrain is a popular choice in the growing compact SUV segment, introducing drivers to GMC's professional grade design and features," said Duncan Aldred, vice president of GMC Sales and Marketing.

GMC teases rugged 2021 Canyon AT4 pickup

GMC promised every model in its lineup would get the AT4 treatment by 2021. Having introduced AT4 versions of the Sierra, Acadia and Sierra HD already, that leaves the Canyon, Terrain and Yukon waiting their turn for the procedure. During a press even for the Sierra HD in Jackson Hole, Wyoming, GMC teased Canyon AT4 as next in line to receive upgraded off-road chops. The automaker had a camo'ed prototype Canyon AT4 in a trailer hooked up to a Sierra HD. When Sierra occupants pulled up the feed from the trailer-mounted camera on the infotainment screen, said occupants got a view of the masked midsize pickup between two walls reading, "The first ever Canyon AT4" and "Coming early 2020." The main mysteries are how extensive the pickup's AT4 transformation will be, and when it will go on sale. The AT4 kit changes depending on model. The Sierra AT4 upgraded performance and looks, with features like a two-speed transfer case, locking rear differential, a two-inch lift and Rancho monotube shock absorbers, skid plating, black-chrome grille and body-colored grill surround. The 2020 Acadia AT4 is mostly about looks, pairing standard all-wheel drive with black trim and wheels, and all-terrain tires. The Canyon's expected to weigh in on the Sierra end of the overhaul, and slide into the lineup between the SLT and top-tier Denali trims. The mods will put it beyond the current All Terrain trim being phased out across the lineup, but leave space between the Canyon AT4 and its Chevrolet sibling, the Colorado ZR2. GMC VP Duncan Aldred said, "They’re going to have different capability levels. The ZR2 is extreme capability. AT4 isnÂ’t positioned as extremeÂ… not intended to rival the ZR2." And the Colorado gets the even chunkier Bison version on top of that. The Canyon AT4 is predicted to join the lineup for the 2021 model year, so although it's "coming early 2020," it might not go on sale until much later in the year. GM's midsized pickup twins will be endowed with changes so mild that neither brand will classify the work with the term "midcycle enhancement." Figure a refining around the grille and lights and a few minor fillips otherwise. Next-generation models of the Canyon and Colorado aren't due until 2023, and there's apparently debate inside GM about an interior refresh for both trucks before then. The Terrain should mirror changes to the Acadia, and it would be a pleasant surprise to see the all-new Yukon also due in early 2020 get serious off-road teeth.
