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.

This week in EVs: Electric Jeeps, Chevy Equinox, reborn VW bus

There's going to be tons of car news next week as the Detroit Auto Show makes its return after 48 years. OK, so the pandemic and the show's shifting calendar only made it feel like 48 years, but January 2019 was still a long time ago. As we await that wave of headlines, let's look back at the substantial week that already was, specifically in terms of the electric car news that broke. Electric Jeep Recon and Wagoneer S blaze trail to brand's EV future Jeep declared Thursday to be 4xe Day as it revealed loads of previously unknown information about its future electrification efforts. The biggest surprise was the extremely cool and 100% electric Jeep Recon. Although it looks like a Wrangler, it's absolutely not a Wrangler replacement, and is indeed quite different for reasons besides its powertrain (independent front and rear suspension, fully enclosed fenders, fixed roof). As the photos attest, though, you'll be able to remove the doors and rear-quarter windows just like a Wrangler. And again, it's electric. Expect the Recon to be one of the most eagerly anticipated new vehicles over the next couple of years. Yes, years, plural. Production will start in 2024 with reservations accepted starting early next year. Jeep Recon View 5 Photos   There was then the Wagoneer S. Despite the name, it isn't a sportier Wagoneer variant or even an electric Wagoneer. In fact, the name is temporary according to chief designer Ralph Gilles. This sleek SUV, which sure looks like Jeep's attempt at a Range Rover Vilar (not a bad thing), will apparently have a 600-horsepower electric powertrain. It too will be produced in North America starting in 2024 with reservations starting early next year. Jeep Wagoneer S View 4 Photos   There actually WILL be an electrified Wagoneer, however: the Grand Wagoneer 4xe PHEV. That's good since the Grand Wagoneer gets pretty atrocious fuel economy. Details were light regarding specs, but we did get a half-decent photo. Finally, the first of these electrified Jeeps to launch will be the Avenger. Yes, Chrysler/Stellantis is dusting off an old Dodge name for a Jeep. That Dodge in question wasn't sold in Europe, though (good for them), which is important since the Jeep Avenger will only be sold on the other side of the pond. It's mechanically based on the same platform as several French Stellantis EV SUVs, and only goes 249 miles on the far more generous European WLTP test cycle.

Nissan Leaf sales drop, new Chevy Volt climbs in November

This is probably just how things are going to be from now on. With the second-gen Chevy Volt available in some states and Nissan dragging its heels on getting a true new version of the Leaf onto dealer lots, it's no surprise that plug-in vehicle shoppers are turning to the Volt in a big way. Yes, we know that a pure EV and a PHEV are not the same and that the Volt and the Leaf are quite different cars, but after all of this time tracking the two plug-in sales champions, we feel obliged to continue our monthly look at who's selling how many of what. Here goes. We'll start with the mediocre news. That'd be the Leaf sales, which came in at just 1,054 units last month. That's the lowest monthly sales total for all of 2015 and, in fact, the lowest month of Leaf sales since February 2013. It's also a 60.8 percent drop from November 2014's sales of 2,687. This despite the fact that you can now get a new Leaf with a longer range of 107 miles (vs. 84) for a higher cost. The new Volt (along with the first-gen Volts that are still being sold out there), on the other hand, was up 49 percent, to 1,980 sales. That gave the Volt its best November ever, "on both a total and retail basis," GM says. The Volt beat the Leaf in October, too, and we suspect this is going to be the story until Nissan figures out how to get people excited about a five-year-old model or introduces the second edition. As always, we'll have a fuller wrap-up of US green car sales in our By The Numbers report soon. Green Chevrolet Nissan Electric Hybrid ev sales
