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.

Recharge Wrap-up: Tesla's Europe plans, Chevy Bolt details

Hybrid Cars takes a close look at the battery cooling system and gearbox in the 2017 Chevrolet Bolt. While information is still limited, we can make educated guesses about the car's inner workings. The Bolt's liquid battery cooling system appears simpler than that of the Chevy Volt, eschewing active inter cell cooling plates for what appear to be bottom cooling plates. The Bolt has a coaxial gearbox, with the electric motor and the drive shaft on the same axis. It uses a simpler parallel-helical gear set rather than the planetary reduction set used in the Chevy Spark EV. These simplifications have the benefit of helping lower the cost of the Bolt.

While a handful of countries in western and central Europe have an established Supercharger network, many European countries still have no Tesla presence. That should change this year, as a map of planned locations includes Spain and Portugal, Ireland, Scandinavian and Italian expansions, and the first Superchargers in many eastern European nations, including Poland, the Balkans, Russia, Ukraine, Romania and even Moldova. By the end of the year, you should be able to take that electric road trip from Lisbon to Moscow you never knew you were planning. Read more at Teslarati. National Biodiesel Board CEO Joe Jobe sat down for an interview with the Tampa Bay Times. In the interview, Jobe discusses biodiesel's environmental impact and relationship with the fuel market. He talks about its production, and its differences from the other major biofuel, ethanol. Jobe says the biggest challenge is dealing with the petroleum industry, which biodiesel needs to work with despite their differences. "It's a threat when you have the largest, wealthiest most powerful industry in human history making it a top priority to eliminate policy that is aimed at helping incentivize renewable energy," says Jobe.

2015 Chevy Tahoe gets Police Patrol Vehicle treatment

That was fast. Mere days after showing a Police Concept based on the 2015 Tahoe at the SEMA Show, Chevrolet has announced that it will build a PPV model based on the SUV to do battle with the Ford Police Interceptor Utility (Explorer) and Dodge Durango Special Service.
You'll recall that the Tahoe has been police staple for several years, predating both the Explorer and Durango police variants, so the fact that the new model would spawn a police variant is hardly surprising. Like the civilian model, the 2015 PPV benefits from a more efficient 5.3-liter, direct-injection V8 that pumps out 355 horsepower and 383 pound-feet of torque. It also features more high-strength steel, offering better crash protection, on top of optional safety items like lane departure warning, forward collision alert and a Safety Alert Seat.
The press release is rather light on police-specific items, aside from the auxiliary battery, which keeps the myriad of electronics in a modern police car running even when the engine isn't. Lightbars, 17-inch steel wheels on Goodyear Eagle RS-A tires and a push bar round out the mods for the Tahoe PPV. The cabin features a revised center console and room for laptop and other equipment mounts.
