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.

Consumer Reports declares most and least loved cars [w/video]

Consumer Reports is crunching the numbers from its annual owner-satisfaction survey, and part of that process is finding out how attached drivers are to their cars. CR simply asks readers of models up to three years old if they would buy the same vehicle again in light of their entire ownership experience, and tallies the results. After looking at the responses for about 350,000 vehicles, it turns out that people really love a certain California-built, electrically powered luxury sedan. That's right, this year's the overall winner was the Tesla Model S with a whopping 98 percent of owners saying they would purchase another one (the Model S also won this award last year, with 99 percent satisfaction). The Chevrolet Corvette Stingray came in a close second with 95 percent of drivers hoping to park another one in their garage. A few models weren't quite so favored, though. The Nissan Versa Sedan was the least loved model among its owners; a mere 42 percent said that they would purchase another. The aging Jeep Compass didn't do much better, with just 43 percent of drivers willing to buy the softroader again. On average, about 70 percent of owners say they would buy their car again, and only four cars ranked below 50 percent in CR's findings. Check out the video above to see some of the winners and losers in a few of CR's categories. If you're a subscriber, you can check out the full list on its website.

GM recalls 64k 2011-2013 Volts over carbon monoxide fears, stop sale on Trax and Encore

General Motors is recalling 50,249 Chevrolet Volts from the 2011-2013 model years in the US and an additional 13,937 exported examples because of fears over carbon monoxide buildup. According to a statement, if a Volt is accidentally left on while running on electric power, its internal combustion engine would eventually kick on to charge on the battery. If this happens in an enclosed space, then carbon monoxide can fill the area, leading to a potential exposure to the dangerous gas. According to GM, there have been two injuries reported due to this issue. To fix the problem, there's a software update to limit the time the vehicle can idle. According to Automotive News, GM is also issuing a stop sale on about 2,300 examples of the 2015 Chevrolet Trax and Buick Encore. In these compact crossovers, it's possible that the steering column assembly could touch the power steering circuit board and cause damage over time. This could potentially cause the system to stop working. Automotive News indicates that the automaker is still working with the supplier to get the necessary parts to repair this problem. General Motors is recalling 50,249 Chevrolet Volts in the U.S. from the 2011-2013 model years to implement a software update that will limit the amount of time a vehicle can be left idling in the "on" or "run" position. If a driver exits the vehicle and inadvertently leaves the vehicle "on" by failing to react to cues and warning chimes emitted by the vehicle, the vehicle's high-voltage battery will drain after a period of time and the gasoline engine will begin to run. If the gas engine runs for a long period of time within an enclosed space, such as a garage, carbon monoxide could build up. GM is aware of two injuries, both related to carbon monoxide build up. The total recall population including Canada and exports is 64,186. Related Video:
