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.

2023 GMC Hummer paint choices are out of this world

The 2022 GMC Hummer EV Edition 1 came in one color: Interstellar White. Despite production issues potentially pushing Edition 1 builds into the 2023 model year, the Edition 1 will stick to being bathed in that single brilliant shade. GM Authority says it got access to the color palette on the way for the standard series Hummer EVs due next year that shows seven new galactic-themed choices on the way. Interstellar White carries on, joined by Void Black as the only no-cost colors. The others are: Afterburner Tintcoat, said to be an orange hue; Deep Aurora Metallic, said to be some kind of bronze; Meteorite Metallic, said to be a gray; Moonshot Green Matte, which we've seen on early shots of the Hummer EV SUV; Supernova Metallic, said to be dark blue; Tide Metallic, said to be a different shade of blue. GMA didn't get intel on pricing for the cost-extra colors; right now, the most expensive palette option for GMCs is White Frost Tintcoat for $1,095. However, the outlet believes Moonshot Green Metallic will be "extremely limited" and charge a super premium price. If that ends up being the case, it suggests GM has a thing about getting big green for special greens. Cadillac made Dark Emerald Frost a late option on the 2022 CT4-V and CT5-V Blackwings and charged $3,925 for the matte paint job. The brand ended production of Dark Emerald Frost in January, making the color doubly exclusive since it was offered for less than a year at the same time as customer demand far exceeded the number of Blackwings available. Anyone wanting Moonshot on their Hummer should get in line early.  The 2023 GMC Hummer EV will begin production later this year. Last month, GM raised prices for the coming model year by $6,250, and raised the destination fee to $1,995. For the moment, that makes the Hummer EV 2 start at $86,245, the EV 2X at $96,245, and the EV 3X at $106,245. Related video: This content is hosted by a third party.

GM extends production cuts, affects Cadillacs, Camaro and Acadia

General Motors is extending production cuts at some of its North America factories due to a chip shortage that has roiled the global automotive industry, the U.S. carmaker said on Thursday. The move's impact has been baked into GM's prior forecast that the shortage could shave up to $2 billion off this year's profit. GM's Lansing Grand River assembly in Michigan will extend its downtime through the week of April 26. The plant makes Chevrolet Camaros and Cadillac CT4 and CT5 sedans. It has been out of action since March 15. GM's Spring Hill assembly in Tennessee will shut down for two weeks starting the week of April 12. The plant makes the Cadillac XT5, XT6 and GMC Acadia. The company said it has not taken downtime or reduced shifts at any of its more profitable full-size truck or full-size SUV plants due to the shortage. The news was first reported by CNBC.
