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.

Chevy Silverado gets star-studded treatment at SEMA

Chevrolet has quite a presence ready for the 2015 SEMA Show, including custom takes on the Camaro and Spark. As one of the company's most popular models, the Silverado isn't left out of the fun, either, thanks to a trio of concepts to highlight what's possible for the aftermarket event. Camouflage is supposed to blend in, but the naval-inspired, Razzle Dazzle design on the Silverado Special Ops Concept should make the truck pop under the lights at the Las Vegas Convention Center. Based on a Silverado 1500 Z71, the pickup is conceived as a "rescue vehicle special-operations forces." To get behind enemy lines, it packs extra LED lighting, wheel flares for off-road tires, and a GearOn utility rack in the bed. Plus to help get away, Chevy Performance fits an air intake, exhaust kit, and concept six-piston brakes. The Silverado Realtree Bone Collector Concept (above) also wears camo for SEMA, but it's for enjoying the outdoors rather than getting out of battle. Camouflage company Realtree and The Bone Collector host Michael Waddell help with the design for this custom truck that features 22-inch black wheels, a front push bar, LED light bar, and assist steps all from Chevy Accessories. With leather upholstery, Apple CarPlay, and Android Auto inside, the drive to and from the woods should be comfortable, as well. The Silverado 3500HD Kid Rock Concept rounds out this trio and features patriotic styling from the eponymous rock star. "I wanted the design for the truck to be bold, but with features and elements that wouldn't be out of reach for working-class guys," he said about the design, and Kid Rock even visited the factory in Flint, MI, to meet members from UAW Local 598 for some inspiration. The result features a custom chrome grille with a Born Free logo and chrome exhaust stacks. For added excitement, two Gibbs Sports Quadskis are hooked up on the trailer behind it.

It is based on the Silverado 1500 Z71, which features a new front-end design and new technologies built into its strong, high-strength steel body structure and fully boxed frame, and draws its design inspiration from naval design aesthetics.
