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 confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models. Scroll down for a press release highlighting the automaker's future fuel-saving initiatives.

Weekly Recap: Volkswagen moves forward under Muller

Most stunning was the speed of it all. On the morning of September 18, Volkswagen AG stood atop the automotive world. It was profitable and sold more cars than Toyota and General Motors, its two main rivals for global supremacy. By nightfall, the company would be embroiled in scandal. Revelations the German auto giant cheated on diesel emissions testing in the United States reverberated from Washington to Wolfsburg, Germany. What started out as a problem with 482,000 VWs and Audis in the US exploded into an international scandal. Millions of vehicles have the rigged software, meaning VW broke environmental rules as its cars spewed pollutants all over the world. The fallout began immediately. Volkswagen CEO Martin Winterkorn – one of the most respected and capable executives in the business – apologized on Sunday and Tuesday. On Wednesday he resigned. As the week progressed, the company's stock took a beating and credit agencies threatened to drop their ratings. VW dealers and owners said they felt betrayed. The automaker hired a law firm that defended BP after the Deepwater Horizon oil spill. The EPA is already extending its testing procedures to look for "defeat devices" like the ones used by Volkswagen. On Friday the company announced a major restructuring. Matthias Muller, Porsche's chief for the last five years, took over as CEO of Volkswagen and is charged with picking up the pieces of a shattered company facing regulatory action and lawsuits. With GM, Toyota, and Takata scandals still fresh, Volkswagen will likely experience unprecedented levels of scrutiny. Additionally, VW's markets in the United States, Canada, and Mexico will be combined into a North American region under the leadership of former Skoda boss Winfried Vahland, though US chief executive Michael Horn will stay on. The company is also realigning its brands by specialty and streamlining its board. Firings, government action, restructurings, and international outrage – things that usually build up over months or years – all occurred in about a week. With dizzying speed, Volkswagen's future has changed dramatically. It all happened, it's still happening, so fast.
