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.

2014 Chevy Silverado High Country spied wearing trappings of new luxury trim

Spy photographers have spotted the new Chevrolet Silverado High Country and GMC Sierra Denali out on public streets for a little testing. From the looks of things, the Silverado will receive a much-differentiated front fascia along with special badges and those honking 20-inch chrome wheels. Expect to find a more posh interior as well. Likewise, the Sierra Denali will wear a tweaked nose with the familiar Denali bling. The one of the GMC trucks spotted here rolls on 21-inch gunmetal wheels instead of the 20-inch chrome pieces of the High Country.
Word has it both trucks will go on sale after the Texas State Fair this summer. While General Motors hasn't said for certain what we can expect to find under the hood, we'd be surprised to see anything outside of the range of engines found in the standard Silverado and Sierra models. That means buyers should be able to get their hands on the efficient, 23-miles per gallon 5.3-liter V8.

2016 Chevrolet Camaro: Notes from the reveal

The 2016 Chevrolet Camaro debuted Saturday evening in Detroit at an enthusiast-oriented event near the city's IndyCar course. While the big news was the Camaro's 200-pound weight loss, tighter chassis, and a snorting new V8, plenty of other morsels of Camaro info came out. Here's some of the more interesting stuff we heard. • The 2.0-liter inline four-cylinder is the first turbocharged engine in a Camaro. • The LT1 borrowed from the Corvette Stingray marks the third time a Camaro has used an engine with that badge. It was previously used in 1970-72 (Z/28), 1993-97 (Z/28), and 1996-97 (SS). • The Camaro was revealed in a tent before nearly 1,000 enthusiasts, General Motors executives (including CEO Mary Barra) and mere feet from the Grand Prix course where IndyCars will run in two weeks. • Chevy hopes to continue to attract new customers with the Camaro and said 63 percent of the fifth-generation buyers were new to the brand. • GM product boss Mark Reuss neatly summed up the Camaro's handling character. "It's wicked fast and extremely nimble." • Reuss on the design goal: make it "look like a car for tomorrow instead of a car from yesterday." • Reuss' first car was a 1967 Camaro, and he's reiterated his passion for the car. "People want to be seen in a Camaro, and that never goes away." • Chevy North America president Alan Batey said he plans to line up a red Camaro as soon as the order bank opens. We assume he'll have early access to that. • Though the appearance is similar, the sixth generation of the Camaro appears a little sleeker and is more aerodynamic thanks to 350 hours in the wind tunnel. Only two parts, the SS badge and the rear bow-tie emblem, are carryover. • Al Oppenheiser, the Camaro's chief engineer, said most of the options (except Magnetic Ride Control, which is SS exclusive), will be offered on the inline four. The engine will be capable of propelling the Camaro to a sprint to 60 miles per hour in well under six seconds. "We don't want to ... make it feel like an excuse car," he said. • Without revealing specifics, Oppenheiser said every Camaro variant will be faster than the model it replaces. •The interior is vastly improved. We got an up-close look in the cabin of one of the cars revealed with a red and white layout, and the materials are much better. The setting is more colorful, and 24 different ambient lighting shades are available. Related Video:
