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.

Former Fisker CEO has some advice for Tesla Motors

Former Fisker Automotive CEO and ex-Chevrolet Volt vehicle-line director Tony Posawatz has some words of caution for Tesla Motors. The long-time automaker executive questions the California automaker's long-term viability – and gives some praise – in a talk with Benzinga, which you can listen to below. While the all-wheel-drive D that Tesla unveiled earlier this month in Southern California wowed a packed crowd, Posawatz (starting at around minute 4:45 in the interview) says Tesla would've been better off taking the resources it expended toward that Model S upgrade and directed them towards speeding up the development of a more affordable plug-in. Perhaps a number of investors agreed, since the company's stock fell the day after the D was announced. Posawatz says Tesla has been over-reliant on the sale of ZEV credits. Posawatz also says that Tesla has been over-reliant on the sale of zero-emissions vehicle credits in California for its earnings and questions whether the automaker will ever work at a large enough scale to sufficiently drive down costs and make consistent profits. Tesla CEO Elon Musk would take issue with this characterization. Posawatz first made his mark in the plug-in vehicle world when he was the vehicle-line director at General Motors for the Volt extended-range plug-in from 2006 to 2012. Later that year, he joined extended-range plug-in maker Fisker Automotive as its CEO, though quit that job during the summer of 2013 as the company was descending into insolvency. He joined the Electrification Coalition this past March. News Source: Benzinga Green Chevrolet Fisker Tesla Electric PHEV Tony Posawatz

2018 Hyundai Accent vs subcompact sedans: How it compares on paper

Hyundai first revealed the new 2018 Hyundai Accent a few months ago, but that debut was in Canada for the Canadian-market car. We didn't get our look at the U.S. version until just recently, which is when we also finally got plenty of specifications on the little car. So as we did with the Genesis G70, we've brought you a breakdown of the Accent's specs and some of the segment's best and most popular: the Nissan Versa, Kia Rio, Chevrolet Sonic and Toyota Yaris iA. Before we get to the chart, let's give you a quick reintroduction to the 2018 Accent. The subcompact is completely new this year, and under the hood is again a naturally aspirated 1.6-liter four-cylinder engine. It makes 7 fewer horsepower and 4 fewer pound-feet of torque than the outgoing model with totals of 130 horsepower and 119 pound-feet. This drop in power probably won't be noticeable, though. It's also available with either a manual or automatic transmission, both featuring six speeds. Fuel economy hasn't been announced, but the Rio's numbers below are probably a good indicator as they share powertrains. The one thing that isn't available with an Accent is a hatchback. According to Autoweek, the hatchback was canned with the assumption that hatch buyers would simply purchase an example of the upcoming Kona crossover. But if you want a traditional subcompact hatch from South Korea, Kia is happy to oblige, as the Rio is still available as a hatchback. Learning that the Kona may have killed the Accent hatch causes us to wonder if Kia brought the Rio hatch to the U.S. because it wasn't planning on offering the Stonic.
