VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

Car dealers, factories and ports close in the path of Hurricane Florence

Hurricane Florence has caused CarMax to close four stores in North Carolina, South Carolina and Virginia. The closed locations are in Myrtle Beach, Charleston, Winterville and Virginia Beach. It is possible for the company to close more stores, reports Automotive News. Daimler and Volvo have also shuttered their manufacturing facilities in the region to prepare for Florence. The storm is expected to reach North Carolina and South Carolina today or tomorrow. Automotive News says every coastal car dealer it reached on Tuesday was closing, and others not in the projected landfall area were monitoring the situation. There are approximately nine million vehicles in operation in the area that Florence is expected to hit, with a vehicle density of 162 vehicles per square mile. It is likely that not as many vehicles will be lost as during hurricanes Harvey and Irma, as population is less dense; areas affected by those storms had over 300 vehicles per square mile. The chief economist of Cox Automotive told Automotive News that some 20,000 to 40,000 vehicles could end up flooded if Florence keeps its path; however, recent reports have indicated Florence has weakened to a category 2 hurricane on Thursday. Tesla has again unlocked more range for some of its older models to make evacuation easier; the same was done a year ago in preparation for Hurricane Irma. As well as automotive manufacturers and dealers, automotive transport providers are readying for the storm and clearing cargo away. The container and auto terminals at Port Charleston will be closed from Thursday to Saturday, affecting part shipments to the BMW manufacturing facility in Spartanburg; BMW's spokespersons have said no production disruption is expected. Parts are delivered via railroad to Spartanburg by Norfolk Southern, which is also suspending operations for the time being. Vehicle hauler United Road has moved its rigs to safer regions and suspended deliveries, and car carrier vessels are trying to make it away from the storm's path in time.

These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.
