GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

GM recalls Chevy Express, GMC Savana over rollaway concern

The National Highway Traffic Safety Administration has issued a recall notice for a small number of General Motors fullsize vans due to possible rollaway concerns. On certain 2013 Chevrolet Express and 2013 GMC Savana models, it is possible to remove the key from the ignition without the shifter being in park.
Only 980 total units are being affected by this recall, and GM is fixing the issue by replacing the ignition cylinder and associated keys. Affected Chevy vans were built during most of November and December while its GMC counterpart was only built for a week in November. The recall goes into effect on January 23, and to find out if your vehicle applies to the recall, the GM and NHTSA contact numbers can be found on the official recall notice, which is posted below.

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.
