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.

VW stock plummets as Euro markets open

The fallout from Volkswagen's installation of an emissions "defeat device" on nearly 500,000 diesel-fueled models in the US is already hitting the automaker hard on the German stock exchange. At one point, the share price plummeted 23 percent to erase the equivalent of $17.6 billion in value. Things eventually bounced back slightly to a still severe 19.23 percent loss, according to Bloomberg as of this writing. The scandal couldn't come at a worse time for chairman Martin Winterkorn. The VW supervisory board takes up the issue of renewing his contract on September 25, Bloomberg reports. If things get bad enough, the door could be open for a new boss to step in. Dealers in the US might start feeling the pain from this, as well. Affected 2015 VWs that are still at showrooms are now under a stop sale. Until the issue is straightened out, the Environmental Protection Agency isn't certifying the company's 2016 diesel models with the 2.0 TDI, either. The diesel emissions problem was first discovered by research from West Virginia University and the International Council on Clean Transportation. In some cases, the engines can produce 40 times more nitrogen oxides than allowed. The automaker could be on the hook for $18 billion in fines for the breach, but the actual figure is expected to be lower. In response, Winterkorn has issued a public apology and ordered an independent investigation into what happened. The EPA and California Air Resources Board have also been looking into the situation. This could become an international problem, though. According to The Detroit News, European authorities might begin similar inquires to check the automaker's diesel emissions there.

VW Golf GTI wrung out by Chris Harris

Enthusiasts like nothing more than to crucify modern interpretations of their favorite performance models for failing to live up to some imagined ethos. Even the Volkswagen GTI has suffered its fair share of slings and arrows for growing in size and curb weight. Chris Harris recently spent some time with the all-new MK VII GTI to find out if growing up means giving up on what makes the machine so special.
Judging by his comments, Harris certainly doesn't think so. Yes, the new GTI is considerably more comfortable than its predecessors, but that's hardly a bad thing. The multitude of driving modes actually seem to add depth to the car rather than simply try to force one tool to do many jobs, and Harris even finds the machine's electronic power steering tolerable. As a result, Harris goes so far as to call the Volkswagen GTI "one of the best cars to actually own." How's that for high praise? You can watch the video for yourself by scrolling below.
