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 adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.

The Volkswagen Group switches official language to English

The Volkswagen Group can't be fairly thought of as entirely German anymore, so the news that the company is switching its official language to English to help attract managers and executives is a rational, if surprising, decision. While many VW Group companies are still staidly German in character and culture, consider the other companies that it controls: Bentley (British), Bugatti (French), Ducati and Lamborghini (Italian), Skoda (Czech), Scania trucks (Swedish), and SEAT (Spanish). Not to mention the large Volkswagen Group of America operation, which constructs cars in Chattanooga, TN. Volkswagen's explicit motivation is to improve management recruitment – making sure the company isn't losing out on candidates for important positions because they can't speak German – and that's inherently sensible in a globalized economy. Particularly considering, like it or lump it, that English is the lingua franca of said global economy. It also should make it inherently easier to communicate between its world-wide subsidiaries and coordinate operations. It's hard to say for sure if this will have any impact on the consumer, although it's easy to see the benefits if, say, VW Group hires some American product planners or engineers and they push for features and designs that more closely suit American needs. After all, the US is a hugely important market for any manufacturer, and so the switch to English almost certainly has something to do with the outsized influence of the US in the global economy. And there doesn't seem to be a downside from a purely rational perspective, although it could mean that the Group's corporate culture becomes less German. Whether that's a good or a bad thing depends on your perspective.
