2020 Chevy and GMC HD truck spy shots reveal LED lighting

With Chevy and GMC's 1500 series pickups just starting to roll into dealerships, our attention naturally turns to the Heavy Duty 2500 and 3500 series trucks. We've seen these HD trucks testing already, but thes latest spy photos give us our first good glimpse of the two HD trucks' headlights through some translucent camouflage, and their designs appear very interesting and quite different from each other. The 2020 Chevrolet Silverado HD looks to be getting a striking set of LED lights that flank the grille. A previously released teaser image of the truck shows that the front lighting elements are split by a bulky wing that branches out from a big, upright chrome face, and both top and bottom units seem to incorporate LED slashes. If you look closely at the images, you can easily make out the Chevrolet script cut into the grille's top edge. Amidst a bevy of Chevy test trucks was one lone GMC model in a dually configuration, and the Sierra HD also appears to have some LED accent lighting up front. Unlike the boomerang-shaped Chevy LEDs, GMC's version sports a shoulder-like right angle of light bars. Assuming these are production-level lighting units, it seems the Sierra HD will stick pretty close to the face of GMC's latest light-duty pickup truck. We're still waiting for confirmation on what range of powertrains will be available in GM's next-gen HD trucks, but we're sure there will be both gasoline- and diesel-burning engines on the ordering sheet. We expect to hear official details on the trucks sometime soon.

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.

GM investing $2 billion in Tennessee plant to build Cadillac Lyriq, other EVs

DETROIT — General Motors said on Tuesday it will invest $2 billion to convert its Spring Hill, Tennessee, factory to produce electric vehicles, starting with the new Cadillac Lyriq, alongside existing combustion-engine Cadillacs. Spring Hill will be GM's third U.S. electric vehicle factory, along with existing plants in Detroit and Orion Township, Michigan. The Tennessee plant was built in 1990 as the exclusive source for GM's now-defunct Saturn brand. The Cadillac Lyriq crossover is slated to go into production in Spring Hill in late 2022, according to AutoForecast Solutions (AFS), which tracks industry production plans. AFS said it expects some electric vehicle production will be announced at a later date for a factory in Mexico. Among additional investments, GM on Tuesday said it will spend $32 million at its truck plant in Flint, Michigan, to increase production of the Chevrolet Silverado and GMC Sierra heavy-duty pickups. GM will spend $100 million to shift production of the redesigned GMC Acadia crossover from Spring Hill to a plant near Lansing, Michigan. Spring Hill will continue to build the gas-engine Cadillac XT5 and XT6 crossovers. The plant also will build other future electric vehicles in addition to the Lyriq. The automaker's plans for investing in U.S. factories comes with two weeks left in the U.S. presidential election campaign. President Donald Trump and Democratic rival Joe Biden are competing for support from auto workers in Midwestern swing states. GM Chief Executive Mary Barra has outlined plans to invest $20 billion by 2025 in new electric vehicles and battery technology. The automaker is spending $2.2 billion to overhaul and retool its Detroit-Hamtramck factory to build a GMC Hummer EV electric pickup truck in late 2021, followed by an automated robotaxi and other electric vehicles. GM builds its electric Chevrolet Bolt at a large assembly plant north of Detroit.
