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.

Weekly Recap: GM plans massive new paint shop at Chevy Corvette factory

General Motors is laying out some serious green to maintain the Chevy Corvette's expansive color palette. The automaker is breaking ground on a new paint shop this summer that's part of a $439-million investment to upgrade the 34-year-old Bowling Green, KY, factory that builds the Stingray. The massive new structure will total 450,000 square feet, nearly half the size of the current 1-million square-foot facility. Construction is expected to take two years and won't impact Corvette production. The upgrades include new robots that save paint and create a better finish, longer, more efficient ovens to bake in the finish, and LED lighting. There's also a dry scrubbing booth technology with a limestone handling system that eliminates waste. GM has invested $135 million in the factory in last four years for the changeover to build the C7 and to relocate its Performance Build Center to Bowling Green. The improvements continue to modernize the Kentucky factory, which has become a tourist attraction in its own right, as more than 56,000 enthusiasts visited it last year. The upgrades are part of a $5.4-billion investment GM confirmed in April that will remake its US footprint in the next three years. The Bowling Green expansion underscores GM's continued commitment to the Corvette, which sold nearly 38,000 copies around the world last year, an eight-year high. "With this major technology investment, we can continue to exceed the expectations of sports car buyers for years to come," North American manufacturing manager Arvin Jones said in a statement. OTHER NEWS & NOTES Takata recall hits 34 million vehicles The National Highway Traffic Safety Administration expanded the Takata airbag recall to an almost unthinkable 34 million vehicles on Tuesday. The recall is part of an agreement reached by the two sides where Takata admitted some of its airbag inflators have a defect, and the deal compels the company to comply with all future regulatory actions and investigations. Takata's airbag inflators were produced with "a propellant that can degrade over time" and lead to ruptures, NHTSA said. Six deaths have been attributed to the flaw worldwide. Investigations conducted by Takata, automakers, and others have not determined the exact cause of the inflator problem, but NHTSA said moisture appears to alter the propellant's chemical structure. It then ignites too rapidly, creates too much pressure that ruptures the inflator, and blasts shards of metal at passengers.

2016 Chevy Corvette Z06 C7.R Edition brings track style to the road

The Chevrolet Corvette has a long history of excelling at endurance racing, and continues to dominate today. To celebrate that legacy, Chevy is bringing some of the look of its track machine to the road with the 2016 Corvette Z06 C7.R Edition. These machines might be gone faster than the racecar's lap time around Le Mans, because the company is building just 500 of them. All of these track-inspired, special editions are based on the 650-horsepower, supercharged Z06 in the top 3LZ trim, and they also come equipped with the Z07 Performance Package that includes carbon-ceramic brakes, adjustable aero elements, and Michelin Pilot Sport Cup 2 tires. Offered as a coupe or convertible, these 'Vettes use some tricks to match the style of the C7.R. They're available in the racer's traditional bright yellow livery, but black is optional. Unpainted carbon fiber trim (including material for the hood) and grilles that are painted Spectra Gray Metallic also add to the motorsport look. The car rides on a set of black wheels with Corvette Racing logos on the center caps. Inside, buyers of this limited edition are nestled in Competition Sport Seats that are upholstered in Jet Black leather. Suede microfiber accents with yellow stitching cover the steering wheel, gearshift, instrument panel and doors. Plus, there's some additional carbon fiber trim for good measure. Each car also comes with a cover with C7.R graphics. Chevy isn't disclosing the price for the Z06 C7.R Edition yet, but the limited edition model is slated to hit the market later this year.

It's offered in Corvette Racing's signature yellow livery – or black – with coordinated exterior and interior accents. Only 500 examples of the C7.R Edition will be built and all will include the Z07 Performance Package with carbon ceramic brakes, as well as a specially serialized vehicle identification number. They go on sale later this year. "Corvette Racing's legacy and technology were significant influences on the development of the Corvette Z06 and the new C7.R Edition honors the direct link between the racecar and the production model," said Harlan Charles, Corvette product and marketing manager.
