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.

Chevy Colorado and GMC Canyon get trim levels reworked again

GM Authority reports that GM has fiddled with trim packages on the Chevrolet Colorado and GMC Canyon for the 2021 model year, eliminating the base trims on both pickups and implementing small price changes. When the new model year goes on sale, the Chevy will lose the rear-wheel drive Base Extended Cab with the automatic transmission that starts at $22,395 after a $1,095 destination charge. The new entry-level is going to be the Work Truck model with the extended cab in rear-wheel drive, starting at $26,595 assuming the destination charge holds steady. That represents a $4,200 jump over the base 2020 model. MSRPs for the entire Work Truck lineup, from base to the Crew Cab Long Box, rise by $400. Elsewhere in the Colorado line, the four Z71 trims go down by $100, while the two ZR2 trims increase by the same amount. Only the six LT trims don't see any change.  The GMC side is a bit more involved due to previously announced changes. The 2020 Canyon comes in SL, Base Canyon, SLE, SLT, All Terrain, and Denali steps. Last month, GM Authority reported the 2021 Canyon would give all that up for the new names Elevation Standard, Elevation, AT4, and Denali. Since the SL base model retires in 2021, the Elevation Standard takes over at the entry level. Unlike on the Colorado, which sheds one trim, the Canyon lineup gets pared from 20 total combinations of trims, cab sizes, and bed lengths, to 14 total combinations. But like the Colorado, due to the loss of the cheapest configuration, the least expensive 2021 Canyon becomes $4,200 more expensive than in 2020, assuming the destination price remains the same. What's more, the 2021 Elevation Standard pricing adds $700 or $800 to the prices of the 2020 Canyon base and SLE models. There are more increases up the range. The 2021 Elevation trim replaces a combination of SLE and SLT models, bumping prices up by up to $900. In 2020, the least expensive All Terrain model is the Extended Cab Cloth for $37,695. For next year, the least expensive AT4 trim is the Crew Cab Short Box for $39,295. Like-for-like, though, the AT4 represents a $300 premium over the 2020 All Terrain Crew Cab Short Box. Three Denali trims will still stand at the top of the heap, each one going up by $400 in 2021. Until GM details the equipment changes, we won't know how the new pricing equates to value.

Recharge Wrap-up: NEDC's NOx problems, autonomous Chevy Volts

The International Council on Clean Transportation (ICCT) found a significant difference in NOx emissions in Euro 6 diesel cars in NEDC and WLTC testing. While 88 percent of the cars tested met emissions standards for NEDC, NOx emissions averaged five times higher under WLTC, with only 27 percent of vehicles under the limit. WLTC is considered to be a more realistic driving cycle, using hot starts and factoring a higher top speed as well as harder and more frequent accelerations than the NEDC.

Employees will be able to use a carsharing app to reserve a car, which will then drive itself to the set destination. The project will allow GM to collect important data and experience to help the company more quickly develop autonomous driving technology.

The lithium-ion batteries used to power the EV were recycled from other Renault EVs. With the electric Trafic, Carwatt – a company that converts vehicles to use electric power – aims to demonstrate the "circular economy" of batteries, which can provide more value through a longer lifecycle. Read more in the press release below. Carwatt presents a unique automotive application for second-life batteries from electric vehicles. On the sidelines of the COP21 summit, in the Solutions Gallery running from 2 to 9 December 2015 in Le Bourget near Paris, Carwatt and its partners —Renault, Paris City Council, BPI France, the Ales Ecole des Mines Engineering School, and the Bobigny Business Campus — are showing a very special electric Renault Trafic. This prototype vehicle, the only one of kind in the world, is powered by second-life lithium-ion batteries recycled from Renault electric cars. Circular economy at work with electric vehicles When, over time, the batteries of a Renault electric vehicle fall the performance threshold specified for their initial automotive power duty (around 75% of initial capacity), they can still provide valuable service in "second-life" applications before end-of-life disposal at a recycling centre. Experiments are already under way on power storage applications, for example.
