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 brings back Midnight Edition Colorado and Silverado for 2016

Chevrolet is capitalizing on the popularity of last year's shadowy Midnight Edition pickups with new versions at the Chicago Auto Show. The package's darker trim allows buyers to make their trucks look a little more menacing straight from the dealer. The 2016 Midnight Editions don't deviate from last year's monochromatic theme. The trucks feature blacked-out trim from the grille, badges, bumpers, and headlight bezels. The obsidian shades also appear on the side moldings and painted wheels. Chevy completes the dark theme with a black spray-in bedliner. Available with the Z71 package, customers can also get off-road equipment like an upgraded suspension, locking rear differential, and hill descent control – depending on the model. Chevy offered the Midnight Edition for the Silverado and Colorado last year, in addition to other models, and customers couldn't get enough of the dark trucks. "The Silverado 1500 Midnight was by far the most popular model in 2015, as demand outstripped supply in a matter of months. It only made sense to expand our special-edition offerings for 2016, including new Midnight editions," Sandor Piszar, Chevy's truck marketing director, said in the models' announcement. Chevy spokesperson Monte Doran told Autoblog the 2016 Midnight Edition pickups will be available this spring, but he wouldn't comment on pricing. You can get a good look at what to expect in the gallery above and expect live photos soon.

They join a growing portfolio of special-edition trucks whose popularity helped Chevrolet truck sales increase 27 percent last year – double the increase for the total truck market. "We introduced several special-edition trucks in 2015 – each combining equipment and appearance packages designed for specific enthusiasts in mind," said Sandor Piszar, Chevrolet truck marketing director. "They clearly resonated with buyers, as the special editions sold in one-third the time, and to younger, more affluent buyers than the industry average. "The Silverado 1500 Midnight was by far the most popular model in 2015," Piszar continued, "as demand outstripped supply in a matter of months.

GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.
