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.

Next-generation GMC Canyon, Chevy Colorado spied together

With the debut of the next-generation GMC Canyon coming in a couple of months (in off-road-ready AT4 guise no less), it's no surprise that both it and the Chevy Colorado are out testing without the heavy coverings of early prototypes. One of our spy photographers caught examples of both trucks with close-fitting vinyl wraps. This gives us a great opportunity to see each pickup more clearly, but also to compare and contrast the designs. From the front, the GMC features a narrower, but seemingly taller grille. At the top are slender lamps. They seem to be daytime running lights, though, and below them are much larger units that will function as the actual headlights. The prototype shown seems to be one of the AT4 variants, based on the lack of a lower air dam and the opened up corners of each bumper. Small fog lights show up in the lower bumper, too. As for the Chevy, its grille is wider, and it blends into the headlights. The lights are at the top of the grille, and they seem to incorporate the actual headlights, not just running lamps. The grille mesh has some interesting detailing, and there are auxiliary lights below the main headlights. This one seems to be a more mainstream Colorado model since it still has a front air dam, possibly a Z71 model, considering the chunky tires. Not surprisingly, the two trucks are very similar from the sides and the rear. They have cabins that look lower, longer and more squared-off than the current models. The fenders look more punched out and aggressive, too. The main differentiator between the Chevy and GMC are the wheel openings. The GMC has sharp corners and the Chevy has more rounded ones, as is the case with the full-size trucks. As previously mentioned, the GMC Canyon AT4 will be revealed this summer, so likely in just a month or two. The Colorado will likely be revealed this summer, too. It's expected that it will use the turbocharged 2.7-liter four-cylinder shared with the Silverado. Naturally, it will be available with two- and four-wheel drive and a variety of trim levels including the AT4 and ZR2 off-road versions. Related video:
