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.

There are still 6,000 first-gen Chevy Volts on dealer lots

The next-gen 2016 Chevrolet Volt looks to be a pretty fantastic vehicle with more electric driving range, better fuel economy than its predecessor, and a lower starting price. However, if you're looking for a deal, the 2015 model of the plug-in hybrid might not be a bad place to check because Chevy has a ton of them to get rid of. According to The Detroit Free Press, there are around 6,000 examples of the 2015 Volts that are still sitting on dealer lots. That might not sound like a lot, but Chevy only sold 905 of them in April and 2,779 through that month in 2015. It moved 18,805 of the PHEVs for all of 2014. Buyers are in a pretty good spot to haggle at the moment, too, with the a new Volt right around the corner. According to The Detroit Free Press based on TrueCar figures, the current average closing price for a 2015 model is $30,607 before any federal or state tax credits. You can also lease one for 39 months for $299 a month and $1,649 due at signing. In April, Chevy was reportedly offering customers 2.9-percent financing for 48 months and leases with no money down for buyers trading in a vehicle from a competitor. Of course, there's also always the option to buy a pre-owned example. Just a few months ago, prices for used Volts were reportedly as low as $13,000 at auction.
