2022 Chevy Tahoe, Suburban and GMC Yukon get updated transmission

General Motors' full-sized SUVs have slipped in one more change before the year turns. GM Authority reports that the 2022 Chevrolet Tahoe and Suburban, and the 2022 GMC Yukon and Yukon XL equipped with gas V8 engines, will pick up a revised ten-speed automatic transmission. The new unit carries RPO code MHS, and Chevrolet communications rep Catherine Scales told GMA the updated gearbox "allows our manufacturing and dealer teams to more easily align the specific calibration needed for the transmission and can enable OTA updates in the future." It seems GM wants to make it easier to update the transmission's tuning and calibration in the future with the automaker's networked Vehicle Intelligence Platform/Global B electronic architecture. The 10-speed auto comes bolted to the 5.3-liter V8 and the 6.2-liter V8. The 3.0-liter inline-six Duramax diesel continues with the 10-speed automatic already in use. To recap the other changes for the full-sizers, we'll start with the 2022 Tahoe and Suburban, which get a new 12.3-inch digital instrument display to replace the former 8-inch unit and physical gauges. Navigation will be standard equipment displayed on the 10.2-inch infotainment touchscreen on all trims barring the base LS. Lane-keeping assist and parking sensors are also now standard, while reverse automatic braking is added to the Enhanced Display and Alert package on the top trims. Finally, the 6.2-liter V8 option is expanded to the Z71, RST and Premier trim levels, but it requires selecting one or more packages on the Z71 and RST. Moving onto the 2022 Yukon, availability of the 6.2-liter V8 expands to the AT4 trim, and the big V8 comes with a shiny pair of exhaust finishers. Redwood Metallic paint joins the exterior color palette, more wheel options are on offer, and illuminated sill plates can gussy up the rocker panels . An Enhanced Trailering Technology Package adds 13 cameras with the option for an interior accessory camera for those with enclosed haulers. On the safety side, expect reverse automatic braking to join the list of available driver assistance features. Inside, the Yukon welcomes the 12.3-inch digital cluster, the Yukon Denali welcomes the power sliding console as a standard feature instead of a $350 option.  Related Video:

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.

Chevrolet Malibu could last until 2024 before joining the dodo

Automotive News pieced together all available intel on the Chevrolet and GMC lineups, trying to ascertain how much life each model might have left. Concerning the Chevrolet Malibu, the answer is not too much, and the historic nameplate's final years don't look like the glory kind. After a major overhaul in 2016 boosted sales for the ninth-generation sedan to 227,881 units, the 2018 sales fell to 144,542, and this year's are down almost 15% through the end of June. The Malibu is one of two Chevrolet sedans still breathing - the other being the Impala for now - but only for about five more years. AN says there'll likely be a refresh in 2022, followed by a visit from the Reaper in 2024. After that, it could be "indirectly replaced" by an electric vehicle, one of the 23 EVs that GM is working on for 2023.     The Impala will meet the ax earlier despite a recent stay of execution. Production is still set to close in January 2020. In the entire GM stable, Cadillac might soon be the only marque with sedans. The Buick LaCrosse has a date with death, and Groupe PSA won't supply Opels-as-Regals forever.  The Sonic hatchback should say goodbye at the end of 2020, a year before the seemingly eternal Spark is thought to die. Two years after that, according to one report, the Camaro will go back into cold storage, perhaps forever, and AN says an "expected redesign of the car in 2021 was reportedly canceled." Finally, let's give one final shout-out to the Chevrolet Cruze, a global nameplate, which in the United States alone outsells the Malibu, outsold the Camaro by a factor of three last year, and absolutely trounces the Impala, Sonic, and Spark. Even that couldn't get a stay of execution. In more uplifting news, everything's happening on the crossover and truck side in the next few years. The Chevy Bolt is due for a refresh next year, even though it has "become more important for self-driving ride-hailing fleets that GM Cruise plans to operate than for consumers." In 2021, the Bolt-based crossover should bow, first in China, then here. It's said to look like "a mix of the Bolt and Trax" in spy shots. Still waiting for a green light: a possible subcompact GMC crossover called Granite that might make it to market by 2023. The full-sized SUV triplets Tahoe, Suburban, and Yukon could show their new faces in 2020. The Silverado might get an updated interior in 2020 or 2021, while the Colorado and Canyon mid-sized pickups won't get attention until perhaps 2023.
