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.

New Takata problem results in recall of 414 GM vehicles

An airbag-inflator rupture discovered by Takata during testing has resulted in a new recall affecting 414 vehicles from General Motors, including 395 of them in the US. This latest campaign covers 2015 model-year examples of the Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Equinox, Malibu, and GMC Terrain. There are no reported breaks in any of these vehicles on the road, and the company estimates only one percent of them actually have the faulty parts. According to documents submitted to the National Highway Traffic Safety Administration (as a PDF), one side-airbag inflator failed a cold test at -40 Fahrenheit "releasing high pressure gas and propelling the separated components apart." The supplier told GM about the failure the next day. In these vehicles, the safety device might not only burst but the bag could inflate incorrectly, as well. GM and Takata say that a cause is not yet known, but they are "conducting an investigation." GM will begin notifying affected owners via overnight mail on Oct. 19. Dealers will replace the side airbag modules on all of the affected vehicles with new components outside of the suspect lot. All of the removed parts will also be collected for further study. Takata's faulty front airbag inflators have resulted in a serious scandal for the supplier. Initial figures indicated 34 million US vehicles are need of repair, though more recent figures have knocked that down to 23.4 million bad parts in 19.2 million automobiles. GM was already among the dozen automakers with models to fix, and some of its pickups were affected, along with the Saab 9-2X and Pontiac Vibe. GM Statement: General Motors is recalling 395 cars and crossovers in the U.S. because one of the front seat side air bags inflators may be defective. In the event of a deployment, the air bag's inflator may rupture and the air bag may not properly inflate. The rupture could cause metal fragments to strike the vehicle occupants, potentially resulting in serious injury or death. GM is unaware of any incidents involving vehicles with these components, which were part of a lot in which one inflator failed acceptance testing at the supplier. Dealers will replace the side air bag module or modules in affected vehicles. Including Canada, Mexico and exports, the total population of the recall is 414, GM estimates 1 percent of the recalled vehicles may have the defect.

Chevy dials up the razzle dazzle for Special Ops concept

Inspired by naval camouflage schemes used during the First World War, Chevy created the 2016 Silverado Special Ops concept, which is on display this week at the SEMA Show in Las Vegas. Based on the 1500 Z71, this Silverado wears a three-tone paint job that mixes different shades of blue, which Chevy says gives the concept visual depth. The appearance is a riff on early 20th Century color configurations used by the US and British navies. Called razzle dazzle, the look is meant to disguise ships' size, speed, and direction. On the Silverado, it simply adds character and gives the truck a more military bearing. The concept also gets flared wheel arches, a sport bar in the bed with LED lights, and a utility storage system. The grille is fitted with black accents and has a thin LED strip running across the top. Inside, orange is used for the door pulls and glove box handle, and the instrument panel and arm rests have more dazzle coloring. The truck also gets an upgraded exhaust kit, six-piston brakes, and a performance air intake. Chevrolet Introduces Silverado Special Ops Concept Military-inspired truck reinforces capability with go-anywhere style LAS VEGAS – Chevrolet's 2016 Silverado Special Ops concept imagines a unique rescue vehicle for special-operations forces. 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. "This Silverado concept is a multipurpose truck that reflects the go-anywhere, do-anything commitment of special-forces teams," said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports. The naval-inspired camo appearance, called Razzle Dazzle, was developed more than 100 years ago to disguise a ship's speed, direction and profile to the enemy's eye. It is based on a three-tone blue exterior color, marked by a distinctive array of varying colored lines and shapes intended to mask the ship. "We created light, medium and darker shaded areas within camouflage bands flowing down the hood, body sides and tailgate," said Todd Parker, director of design, Chevrolet Accessories.
