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.

2024 GMC Acadia to go big again for third generation

In July, spy shooters caught prototypes of the next-gen GMC Acadia wrapped up tight in camouflage. We couldn't make out any useful aspects but one: The coming third-gen Acadia is larger than the current second-gen. Remember, GMC debuted a smaller Acadia for the 2017 model year, lopping eight inches of length and three inches of width from the first-gen large mid-size SUV to create a smaller mid-size three-row SUV. The new prototypes appeared to show that decision would be reversed, now we have proof thanks to more comments unearthed from GM's recent Investor Day presentations in New York. Caught by GM Authority, automaker president Mark Reuss said, "Alongside the Traverse, we’ll move the GMC Acadia to a little bit different size standpoint. This comes in a little bigger than the old Acadia, so itÂ’s a big transformation for GMC and its part of the market." In a 2016 Automotive News piece about how GMC planned to increase sales volume, AN reported, "One potential avenue: venturing into Jeep's terrain. Industry sources believe GMC is drawing up plans for an SUV based on the same body-on-frame platform that serves as the bones of the GMC Canyon and Chevrolet Colorado midsize pickup. It's in the early stages — it doesn't appear to have been sourced to suppliers yet and the SUV's arrival isn't expected until 2020 or later." The first-gen 2016 GMC Acadia was 200.8 inches long, while a 2016 GMC Canyon Crew Cab with the roughly 5-foot bed was 212.8 inches long. It's thought that truncating the second-gen GMC Acadia to 193.4 inches long and 75.4 inches wide was intended to leave plenty of room for the planned SUV on the Canyon platform. However far that SUV project got, it was reportedly canned in 2018.   Hence an upsized Acadia returns. Reuss' comment about the Chevrolet Traverse could imply what's coming for the GMC, the Chevrolet being 205.9 inches long and 78.6 inches wide. A bigger Acadia could make a better sales proposition against the two-row Terrain, too. The Terrain costs almost $9,000 less than the Acadia and is 182.3 inches long and 72.4 inches wide. It's not clear when GMC plans to show the new Acadia, but the consensus is that it will go on sale for the 2024 model year. Expect an all-new cabin, Super Cruise capability and a front fascia reminiscent of the new Canyon. Powertrain options are a mystery.

GM dealers unhappy about pickup prices

The backlash is beginning. Following General Motors' price hike of the Chevrolet Silverado and GMC Sierra last week, dealers across the country are expressing their ire over increasing prices in the face of rebates and discounts on trucks from Ford and Ram.
Speaking to Automotive News, Sam Pilato, the general manager at Dimmitt Chevrolet in Clearwater, FL, Silverados are "selling very poorly." W. Carrol Smith, the president of Monument Chevrolet in the heart of truck country, Texas, said, "[GM's] position is that the vehicle stands on its own and it doesn't need a bigger rebate. That's not what the market is telling us."
According to AN, that's the general attitude amongst Chevy and GMC dealers across the country, where the twin pickups are getting butchered in sales by competitors offering up to $9,000 off their sticker prices. Part of the problem for GM is that its trucks are arriving on the market near the end of the current F-150's lifecycle, a fact that Ford has taken advantage of.
