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 apprentices prep Golf GTI Dark Shine, Variant Biturbo for Worthersee

Volkswagen not only cooks up some pretty tempting concepts of its own for the GTI-Treffen at Worthersee every year (and encourages its sister brands to do the same), but also gives its apprentices the opportunity to do it. And here's what they came up with this year. Called the GTI Dark Shine edition, the show car features an upgraded 2.0-liter turbo four, pumping out 389 horsepower and 359 pound-feet of torque through its dual-clutch transmission. But that's not all. As you can see, it also has a striking two-tone livery of metallic gray and yellow pearl, along with a stainless steel exhaust, carbon air box, an upgraded aero kit, a 3,500-watt audio system with eight speakers and a thoroughly reworked interior done up to match the bodywork in black Alcantara and carbon leather with yellow trim. The team of 13 apprentices built the show car from a body-in-white over the course of nine months. It follows in a long line of GTI concepts done each year by VW apprentices that stretches back to 2008. This year, however, another team of 14 interns at the plant in Zwickau, Germany, worked up a blue Golf Variant wagon called the Biturbo Edition with the twin-turbo diesel from the Passat good for 236 hp and 368 lb-ft. Another team in the Czech Republic was responsible for the Fabia FUNstar pickup concept. And of course the automakers themselves showcased the radical Golf GTE Sport, GTI Clubsport, Skoda Fabia Combi R5 and Audi TT Clubsport. The lake is calling ... world premiere: Volkswagen apprentices present their Golf GTI Dark Shine at Worthersee event - Other show car premieres: Golf Variant Biturbo Edition (Zwickau) and SKODA FUNstar (Mlada Boleslav) They have followed the call of the lake: 13 Wolfsburg apprentices from Volkswagen and group company Sitech Sitztechnik have traveled to the 34th Worthersee GTI meeting today to present their 395 PS (290 kW) Golf GTI Dark Shine to the public for the first time. Their sporty two-door Golf features a two-tone color scheme. The front is painted in dark Daytona Grey Metallic and the rear in unique R-yellow pearl effect – giving rise to the name "Dark Shine". The Golf GTI Dark Shine is impressive confirmation of the high-quality practically oriented training provided by Volkswagen.

Hyundai tops VW and Buick in China, survey says

You may be aware of the long-time competition in China between Volkswagen and Buick, but another brand apparently should be in that conversation too: Hyundai. In a recently published annual consumer survey, the Korean company actually took the top spot to beat out its German and American rivals in second and third, respectively. The results were part of the China Brand Power Index that interviewed 11,500 people around the nation and was paid for by the country's Ministry of Industry and Information Technology. While Hyundai proved popular with voters, its sales haven't necessarily shown that yet. According to Bloomberg, the brand had falling numbers in China for the first quarter of the year. Even Ford outsold the South Korean automaker in the same period, despite scoring lower on the survey. Meanwhile, Audi ranked as the populace's favorite luxury brand, which is hardly a surprise given the Four Rings' strong sales in China. In January alone the automaker saw a 15-percent boost in volume there. Parent company VW's strong performance was somewhat more surprising, though. State media severely criticized the German automaker in March, and customers protested last year for the allegedly poor handling of a recall.
