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 Cadillac thinks it needs to succeed in Europe to sell cars elsewhere

Ward's Auto has taken an interesting look at the renewed focus General Motors is showing towards Cadillac in Europe. Susan Docherty, president and managing director of Chevrolet and Cadillac in Europe (pictured), says in order for the luxury brand to thrive in China, it first needs to succeed in the old country. The reason? Chinese buyers look to Europe for cues as to what's deemed worthy of the term "luxury." There are hurdles to the plan, however. In addition to the fact that the EU is flooded with high-end nameplates, GM doesn't necessarily have the distribution network in place to put buyers behind the wheel.
Combine that with persistent economic woes and Cadillac's checkered past marred by a lack of diesel engine options and a bankrupt distributor, and the road ahead for the brand looks like less of an uphill climb and more like a straight-up cliff face. But Docherty is optimistic and says she has a plan for the brand. We recommend heading over to Ward's for a closer look at the full read.

Chevy monitors drivers' biometrics while experiencing new Corvette Stingray

We tell you about what a car is like to drive every day, remarking on throttle response, steering weight and feedback, squat, dive, brake fade and a dozen or more other factors of performance. What we can't tell you, though, is what the car does to us - how its performance impacts us, physically. That's what makes this video series from Chevrolet so darn cool.
The Bow-Tie brand rented out Spring Mountain Motorsports Ranch, got several (very) different individuals together, strapped a bunch of sensors to their bodies to record biometric data ranging from heart rate to respiration to brain activity, and then handed them keys to the new Chevrolet Corvette Stingray. The results are explained in a series of videos, devoted to each driver, showing how different people react to the Corvette's performance.
If, like your author, you're a nerd for medical science, this is going to be a fascinating set of videos. If not, it's still pretty cool to see how the body of someone with racing experience, like Gran Turismo creator Kazunori Yamauchi, reacts to tracking a car like the Corvette Stingray compared to the owner of legendary Detroit barbecue joint, Slows BBQ. Take a look below for all six videos from the series, or hop over to the Corvette Vimeo channel for the interactive experience, where you can see all the different metrics.
