Sunday Drive: Subaru Ascends up to the hottest market segment in America

Utility vehicles – in other words, crossovers and SUVs – are so hot right now. Two of our top stories from last week revolve around the utilitarian vehicle, but besides their jacked-up, five-door bodystyles, they couldn't be more different. The 2019 Subaru Ascent is headed into an extremely crowded and competitive segment, where it'll have to go up against industry stalwarts like the Toyota Highlander and Honda Pilot, not to mention upstart contenders like the Volkswagen Atlas. The Mercedes-AMG G63, on the other hand, has very little competition – there simply aren't very many ultra-luxurious, off-road-ready SUVs in the world vying to attract the dollars of the wellest-to-do customers across these United States. Moving on from crossovers and SUVs, our readers remain attracted to classic front-engine, rear-wheel-drive sportscars. The Toyota Supra's upcoming rebirth earns two places on our list of stories worth highlighting from the week that was; one with leaked information from a Japanese magazine, and another with rumors indicating that maybe we shouldn't be quite so excited. And finally, there's the strange case of the long-lost 2009 Chevy Corvette Z06 that one lucky individual happened to find squirreled away in a storage container with just 720 original miles. A high-horsepower head scratcher if we've ever seen one. As always, stay tuned to Autoblog this week for all the latest automotive news that's fit to print. 2019 Subaru Ascent vs Honda Pilot vs Toyota Highlander: How they compare on paper 2019 Mercedes-AMG G63 set to bare its 577-horsepower heart in Geneva Toyota Supra leaks in Japanese magazine ahead of Geneva debut Toyota Supra to be little more than a rebodied BMW Z4?

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.

Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
