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.

Which car should win 2015 World Green Car of the Year?

There were three finalists for the World Green Car of the Year announced about a month ago at the Geneva Motor Show: the BMW i8, the Mercedes-Benz S 500 Plug-In Hybrid and the Volkswagen Golf GTE. With the New York Auto Show upon us and the winner scheduled to be announced tomorrow, we thought it's high time to ask our readers which one should win. There were seven other vehicles named to the finalists list: the Hyundai x35/Tucson Fuel Cell, the Volvo XC90 T8 Twin Engine, the Audi A3 Sportback E-Tron, the BMW X5 xDrive40e, the Kia Soul EV, the Nissan e-NV200 and the Opel Adam 1.0 Direct Injection Turbo ecoFLEX Start.

Horn, Hackenburg, Hatz to be fired as VW diesel scandal deepens

Volkswagen will sack three more high ranking executives, including the head of its US division, as the company's diesel scandal deepens. Reuters reported Thursday morning that the executives are: Michael Horn, who has led VW's US operations since January 1, 2014; Ulrich Hackenberg, who oversaw Audi's research and development; and Wolfgang Hatz, who was in charge of R&D for Porsche. A VW spokesman wouldn't comment in response to an Autoblog email. The moves come in the wake of longtime VW chief executive Martin Winterkorn stepping down on Wednesday. Volkswagen's board said at the time that it expected more personnel changes to follow. Volkswagen's board is scheduled to meet Friday, and Porsche CEO Matthias Muller has reportedly been named as Winterkorn's successor. The German auto giant was plunged into crisis last Friday when the EPA charged that the company manipulated software in its diesel-powered cars to pass US emissions tests. About 482,000 vehicles in the US are affected, and VW estimates 11 million around the world could have the rigged software. The revelations have prompted outcry from governments and regulatory agencies, and in the US, Volkswagen could face a fine of up to $18 billion. The departure of Horn, Hackenberg, and Hatz is a stunning downfall for three of the company's top and most visible executives. Horn had led US operations for less than two years, taking over from Jonathan Browning, who was well-respected but failed to reach VW's ambitious sales targets. Before overseeing Audi R&D, Hackenberg was hailed as a visionary for work in developing VW's modular architectures, which allow the company to save time and money by building many vehicles off the same chassis. Hatz had led Porsche R&D since 2011 and also was in charge of engines and transmission development for all of Volkswagen.
