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.

2019 GMC Sierra spied sporting just a thin wrapping

A new Chevy Silverado is on the way, and along with that comes it's fraternal twin, the GMC Sierra. We've seen spy shots before, but, like the Silverado we saw a few days ago, this is our best look yet. Nearly all of the loose-fitting camouflage has been removed, giving us a decent view of the bodywork. A brief look shows that the Sierra and Silverado will have significant styling differences for this generation. In the past, GMC trucks have been little more than rebadged Chevrolets. That's been changing in recent years, and the divide seems to be growing larger. The grille looks much larger than the Silverado's and there appears to be a small inlet right where the hood meets the front. From the side, we can see that the two trucks have different fenders and beds. The wheel wells on the GMC are squared off at the rear. Compare that to the round wells on the Chevy. Out back, the design is far more similar. Both trucks appear to have rear-facing exhaust outlets. The taillights, too, look to have close to the same shape. A big bulge in the center of the tailgate likely hides a large GMC badge. We still don't have a firm reveal date, but look for some further news this auto show season. Related Video:

GM trademarks 'GearOn,' possibly for pickups

On May 27, a week before General Motors applied for a trademark for the word "Zora," GM filed a trademark application at the US Patent and Trademark Office for "GearOn," characterized as a "truck bed cargo system comprised of tiered storage cross rails, utility rack stanchions, cargo dividers and cargo tie down rings."
We have no idea what it will be or if we'll see it used on anything, but GM Authority reckons it could be GM's name for a pickup truck feature to rival the BoxLink system Ford introduced on the 2015 F-150. BoxLink has been described as having "dozens of configurations of stowable cargo ramps and lockable die-cast aluminum tie-down cleats," giving owners the ability to arrange the bed in they way they need and load unwieldy items like motorcycles without needing extra equipment.
Getting purely speculative, a month ago GM pickup truck engineers said there would be more and more regular updates for the Chevrolet Silverado and GMC Sierra starting next year. Beyond the suspected capability and fuel economy changes GearOn could be one of the "neat things coming in a whole host of areas."
