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.

Best Convertibles for 2022

The past decade has not been kind to the drop-top enthusiast. No matter which dealer you walk into, convertible models have been biting the dust left and right. Nissan Z? Audi TT? Buick Cascada? Volkswagen Eos? All gone. Remember the humble Chrysler Sebring/200? Well, you do now. Fortunately, though, the news isn't all bad. There are still plenty of options out there for those who absolutely must have a convertible. Whether you need something to haul behind your retirement cruiser, a performance car that can go toe-to-toe with the best in the world or just something that allows you to sling the roof back after a long day of on-location business meetings before catching the flight back to your everyday hustle and bustle, there's at least one cabriolet out there to suit your needs. Here are our picks and starting prices for the top convertibles in several categories for 2022.  For the frugal open-top lover: 2022 Mini Convertible ($34,650) Let's face it; gas ain't cheap. But open-top motoring doesn't need to be a wallet killer. The Mini is cheap (at least by 2022 standards) and an absolute joy to drive, so there's really no downside here ... except for the roof. Get it?    For the hardtop lover: 2022 Mazda MX-5 RF ($37,260) / 2022 Chevrolet Corvette Convertible ($69,695) The number of hardtop convertibles has seriously dwindled due to weight concerns and the fact that fabric roofs have gotten so quiet, but there are still some options for those who prefer a more coupe-like look with the roof up. Our picks here are the delightfully Targa-like MX-5 Miata RF and literally any Corvette Stingray — even the hardtop has a removable roof!    For long road trips: 2022 Ford Mustang Convertible ($34,100) The first image that comes to mind for many who are told to visualize an American convertible is the classic Ford Mustang. It's not the only drop-top pony car out there, but thanks to the Camaro's tiny trunk, it's much harder to see the USA in a Chevrolet when a drop-top enters the equation. The Mustang has much more cargo space and a much larger opening, which is likely the difference between keeping your bags under lock and key or leaving them exposed in the back seat.    For towing behind an RV: 2022 Jeep Wrangler ($31,590) While many small runabouts make sense for towing behind a motor home (or nestled up inside a fancier one), the Wrangler has a serious advantage when it comes to RVing: it can easily be flat-towed.

2014 Chevrolet Cruze TD fires up its new diesel motor

Ever since General Motors confirmed plans to produce a diesel-powered Cruze back in 2011, we've been eagerly awaiting its arrival. And as part of the 2013 Chicago Auto Show, Chevrolet has pulled back the cover on its oil-burning compact sedan, set to go on sale in the near future with a starting price of $25,695, not including $810 for destination.
The heart and soul of the Cruze TD (that's its official name) is a 2.0-liter turbo-diesel inline four-cylinder engine rated at 148 horsepower and 258 pound-feet of torque, mated solely to a six-speed automatic transmission. The engine also has an overboost function that will increase torque to 280 lb-ft for up to ten seconds. The full brace of official specs haven't been released, but GM tells us that highway fuel economy will come in at 42 miles per gallon. If that number sounds familiar, it's because the Volkswagen Jetta TDI has the exact same rating. Unlike the Jetta, however, the Cruze TD can run on B20 biodiesel, where as the Volkswagen can only accept B5.
Model-specific changes to this 2014 Cruze TD include an aero kit and unique 17-inch alloy wheels. Inside, there's a full leather interior, and Chevrolet will provide two years of complimentary scheduled maintenance, not to mention a 100,000-mile powertrain warranty.
