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.

2020 Chevy Trax spied sporting design cues from the new Blazer

We saw spy shots in August for what we thought was either a redesigned Chevrolet Trax or new GMC subcompact crossover. At the time we were leaning Chevy. But after this latest batch of spy shots taken near GM's proving grounds, we're now thinking this one is the Trax replacement and the other one was a GMC. For one, the thin row of LEDs looks remarkably similar to the 2019 Chevy Blazer's LED strip. The additional light slightly below that is similar to the Blazer as well, leading us to believe that the next Trax will have a Blazer-esque front end. At first glance, this vehicle looks slightly larger than today's Trax with a much brawnier shape than the current blob-like design. The rear roof cladding could be hiding the same sloped rear window with spoiler hangover we see on the Blazer. Circling back to the other small GM crossover we caught testing, this one doesn't have those Blazer elements. The curved windshield and sloping roof are like those of the GMC Terrain, as are the horizontal grille bars. By contrast, the above car has a straighter windshield and a roof shaped more like the Blazer. One element that does seem to diverge from the new Blazer are the taillights, but they don't exactly look production-ready anyway. If we're right about this being the next Trax (and we're pretty sure we are) then this looks to be a more distinctive vehicle than what it will replace. The mirrors have left their awkward spot on the doors, and it's shaping up to be a much sportier looking crossover as a whole. This vehicle will most likely end up being a 2020 model year car, and if so, we would expect to see undisguised photos of both it and the assumed GMC version next year.

GM follows Ford and Honda in skipping SEMA

The list of automakers skipping SEMA has become longer. First reported by Muscle Cars and Trucks, and confirmed to us by a company representative, General Motors will not have an official presence at the aftermarket show. It joins Ford and Honda in leaving the show. It will be a large hole in the show, with the GM brands typically filling a significant swath of available show space in one of the main halls. GM hasn't provided much explanation for the move, either. The GM representative provided Autoblog with the same statement that Muscle Cars and Trucks got: "GM has made the decision not to participate in the 2022 SEMA Show. The SEMA show has always inspired us, and accessories and performance parts remain an important part of our business." We also asked if we would see any sort of announcements around the time of the show — Ford said it has plans to share some things around that time — however, the GM representative said that the company has no immediate plans for announcements. Certainly things could change between now and the November show, though. SEMA had previously noted that other exhibitors would help fill in some of the space vacated by these major OEMs. Another OEM, Volkswagen, is returning to the show after an absence, which will also help with the display deficit.
