GM may have teased a whole group of electric vehicles

During GM's big CES press conference, the automaker highlighted a number of its upcoming electric car-related projects from delivery vans to the upcoming flagship Cadillac Celestiq. In the middle of it all, a collection of mystery cars sat in the background behind speakers. They were in the dark, lit only with their running lights, and while it's possible they're just generic filler cars or concepts, we think they could be future products. Our best shot of the cars together is shown above, and we can pretty easily identify three of the vehicles. In the center is obviously the GMC Hummer EV. On either side of it are Cadillacs. To the left seems to be the Lyriq crossover, and to the right is the Celestiq sedan. Two of these cars have production dates, and the third has been confirmed for eventual production, just without timing. This is why we think the rest of the cars are upcoming models. The next most easily identified car is on the near right behind the Cadillac Celestiq. It very clearly has a Chevy bowtie illuminated in the running lights. And looking closely, it appears to be a pickup truck. It's difficult to make out anything more than that. The nose does look a bit more rounded and swept back than the brick-like designs of the Silverado truck line. That also squares with what seemed to be the upcoming truck that appeared in the background of yet another GM presentation. GM previously said this electric Chevy truck will be a full-size model with up to 400 miles of range. That leaves us with three more mysterious models. Over to the left behind the Cadillac Lyriq are what appear to be a pair of crossovers. The one on the far left looks low, curvy, and possibly with a fastback roof. The one on the right is taller, boxier, and probably more of a full-size people hauler. It's hard to say much more beyond that. They could be new electric Buicks, which would fit in nicely with that brand's crossover portfolio, and would likely be highly successful in China, where Buicks, crossovers and electric cars are all rather hot commodities. As for the mystery car on the far right, it's quite a puzzle. We can at least rule out Buick and Cadillac, and GMC since it's definitely a car, and a rather small one compared with the other cars on display. That leaves Chevy, and possibly the autonomous division Cruise. We're leaning toward it being a Chevy, since the first Cruise vehicle is going to be a boxy pod of sorts.

Sunday Drive: Performance comes in many shapes and sizes

The Chevrolet Corvette has always stood out as a bastion of reasonably priced performance, and the latest 'Vette has that in spades. And while its expected starting price of around $120,000 certainly isn't cheap, it's an undeniable deal in the supercar world – remember, this thing'll do 210 miles per hour thanks to its 755-horsepower supercharged V8 engine. And did you get a load of that massive rear wing? Team Corvette's longtime foe, the Porsche 911, is similarly hellbent on ultimate performance. And as a reminder of how long the Corvette/911 rivalry has been melting tires we present the 1990 Porsche 911 as reimagined by Singer you see below. It's beautiful, it's green, and it's packing 500 air-cooled horsepower. You don't have to burn gasoline to go fast, as proven by the second-generation Tesla Roadster, which was revealed as a surprise late last week. Elon Musk says it'll be the quickest car in the world with a 0-60 time of just 1.9 seconds. And while you may not think of a semi truck when you think speed, the Tesla Semi can do 0-60 in 5 seconds flat unloaded, or in 20 seconds with a load of 80,000 pounds. Compared to today's crop of diesel semis, that's amazing. Continuing the truck theme, we present an artists rendering of what the next-generation Ram 1500 pickup may look like. Spoiler alert: Ram's mini-semi look is giving way to something much more modern. There may even be a first-of-its-kind split tailgate at the rear. And if you don't think the Ram 1500 has anything to do with performance, we should remind you that it's one of the cheapest ways to get a tire-shredding Hemi V8 engine in America. 2019 Chevy Corvette ZR1: All hail the 755-horsepower C7 king This is the first Porsche 911 to get Singer and Williams' 500-horsepower engine Tesla Roadster surprise reveal | 'Quickest car in the world' Tesla Semi Truck revealed: Here are the key details This could be the next-generation 2019 Ram 1500 2019 Ram 1500 spotted with split tailgate

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.
