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.

2023 Chevy Equinox price goes up a few hundred bucks

Chevrolet and GMC have uploaded the configurators for sibling crossovers the 2023 Chevy Equinox and 2023 GMC Terrain. Both get a few changes to improve performance, and new paints. GM jettisoned the turbocharged 1.5-liter gas engine making 170 horsepower and 203 pound-feet of torque in both vehicles. Replacing it is a different turbocharged 1.5-liter gas engine making 175 hp and 203 lb-ft. The Equinox sends its power through a six-speed transmission, the Terrain fits a nine-speed transmission. On the Equinox, fuel economy in standard front-wheel drive trims holds steady, but the AWD trims lose one mile per gallon in their city and combined EPA ratings. On the Terrain, FWD trims lose one mile per gallon across the board, the AWD trims lose one mile per gallon in the city only. Both models also upgrade to an electro-hydraulic brake system, leaving vacuum-assisted braking behind. The Equinox color palette drops Cherry Red Tintcoat, Seaglass Blue Metallic and Silver Ice Metallic for replaces with Harvest Bronze Metallic, Radiant Red Tintcoat, and Sterling Gray Metallic. Buyers who want the razzle dazzle of the Equinox's optional Blackout and Redline Edition Packages are out of luck at the moment, both appearance flourishes unavailable to order. The Terrain's paint menu drops Cayenne Red Tintcoat, Hunter Metallic, and Quicksilver Metallic for Deep Bronze Metallic, Sterling Metallic, and Volcanic Red Tintcoat. All-wheel drive can be added to any Equinox and Terrain trim for $1,600, save for the Terrain AT4 and Denali that come standard with AWD. Prices for the 2023 Chevy Equinox after the $1,395 destination charge, and their differences from 2022, are: Equinox LS: $27,995 ($300) Equinox LT: $29,095 ($300) Equinox RS: $32,095 ($100) Equinox Premier: $33,195 ($300) New pricing for the 2023 GMC Terrain can only be seen when you visit the configurator's Summary page. The initial Build & Price page shows MSRP before the $1,500 premium on every trim to that pays for the mandatory OnStar with Connected Services plan. After the $1,395 destination charge, the new prices are: Terrain SLE: $31,295 Terrain SLT: $35,295 Terrain AT4: $37,395 Terrain Denali: $39,995  

GMC introduces off-road performance package for Sierra AT4

GMC is giving its off-road-focused Sierra AT4 pickup even more performance with some factory-installed upgrades. The package is called the AT4 Off-Road Performance Package. With it you'll get the 6.2-liter V8 engine upgrade, cat-back performance exhaust system, performance air intake and 18-inch aluminum wheels shod in Goodyear Wrangler DuraTrac tires. The upgraded performance comes in the form of extra power. Thanks to the bolt-ons, you gain 15 horsepower and 9 pound-feet of torque over the 6.2-liter in stock form. This increases output to 435 horsepower and 469 pound-feet of torque — not too shabby. This package is priced at $4,940, and available for order now. That's a hefty price for what amounts to some minimal bolt-on modifications you could easily do yourself. However, buying it through GM means you get to keep your warranty in place. The Sierra AT4 already has more off-road features than a normal Sierra 1500. You're getting a two-inch lift, four-wheel drive with two-speed transfer case, locking rear differentials, skid plates, Rancho off-road shocks and hill descent control. Both the wheels and tires are available as options already, but this package just bunches related stuff together. It'll be up to you to decide if an exhaust and intake are worth the extra dough.
