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.

GM plans to restart production in Mexico on May 20

MEXICO CITY — General Motors is tentatively planning to restart operations at its auto assembly plant in the Mexican city of Silao on May 20, according to a message to workers seen by Reuters on Sunday, as the car industry prepares to exit the coronavirus lockdown. Separately, the president of GM's Mexican unit advised suppliers to prepare to resume operations. “We are now beginning a new phase given the Mexican governmentÂ’s official announcement earlier this week to consider the transportation manufacturing industry as essential for the countryÂ’s economy,” Francisco Garza, president ofGeneral Motors de Mexico, wrote in an email to suppliers dated on Friday that was viewed by Reuters. The reopening of the plant  in Silao would be a positive signal for the auto sector in North America, whose supply lines are highly interconnected between the United States, Mexico and Canada. The plant in the central state of Guanajuato has been idled for weeks due to the coronavirus outbreak. Workers had previously been told to plan to return to their jobs on May 18. A GM spokeswoman said the company could not confirm when it would restart operations at any of its facilities in Mexico because it is awaiting more guidance from the government. The message to the plant's workers came after the government on Friday clarified when the industry could begin easing restrictions imposed because of the health emergency. On Wednesday, the government said automakers could start going back into production from May 18. It then withdrew that advice and suggested the new start date would be June 1. Finally it indicated the sector, which forms the backbone of Mexican manufacturing, could begin operating as soon as next week if companies had the required safety measures in place. U.S. officials and its auto industry have pressed Mexico's government to get its factories open again because American operations depend heavily on parts from south of the border. However, some politicians are wary of opening too fast. Mexico registered its first case of coronavirus weeks after the United States and Canada and the toll of daily infections and deaths in the country reached new peaks over the past few days. The Silao production facility, which makes highly profitable pickup trucks for GM, is one of the biggest automotive plants in Guanajuato, a major Mexican carmaking state. Related Video:

Conquest and controversy conclude the 2014 Rolex 24 at Daytona [spoilers]

If you don't wish to know who won the 2014 Rolex 24 at Daytona, you should avert your eyes right now. We'll even give you a double-space to skedaddle...
For those of you still with us, the first race in the United SportsCar Championship (USCC) is done, but the discussions about it certainly won't end for a while. Daytona Prototypes claimed the first four overall places, the top spot taken by the No. 5 Action Express Coyote-Chevrolet Corvette DP driven by Joao Barbosa, Christian Fittipaldi, Sebastien Bourdain and Burt Friselle. The 16th and final caution of the race bunched the field up for an eight-minute sprint to the flag, so the first place getter finished just 1.4 seconds ahead of the No. 10 Wayne Taylor Racing Dallara-Chevrolet Corvette DP driven by Max Angelelli. Third place went to Brian Friselle in the No. 9 Action Express Chevrolet Corvette DP, 20 seconds down. Chevrolet power hasn't taken the overall win since 2003, eleven years later it scores a one-two-three-four. The No. 6 Muscle Milk/Pickett Racing ORECA-Nissan 03 scored fifth place, the top LMP2 finisher.
The Prototype Challenge class win went to the No. 54 CORE Autosport team of Colin Braun, Jon Bennett, Mark Wilkins and James Gue.
