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.

Vision Mercedes-Maybach 6 teases gullwing doors in video

Because these are the times we live in, automakers tease their biggest and best debuts mercilessly before finally dropping the curtain. That's why we're writing about the Vision Mercedes-Maybach 6 Concept again. Here's a new video, posted on Mercedes' Instagram page, showing even more of the hulking two-door coupe. For one, it looks like Mercedes is revisiting gullwing doors. There's a brief snippet of the doors in the open position with a red light – possibly a brake light – bisecting the roof. The video also gives us a couple of good looks at the taillights, which are super-model skinny, just like the lamps up front. Look close at the rear three-quarter cut, and you'll spot a strong chrome strip that accentuates and breaks up those beefy rear haunches. It's hard to tell where they fit in with the chrome strips on the front fenders and hood, so we'll probably need to wait until the big debut to see how it all works out. As we've said twice already, the Vision Mercedes-Maybach 6 debuts on August 18. Stay tuned. This content is hosted by a third party. To view it, please update your privacy preferences.

Daimler, Geely mull China as production hub for hybrid powertrains

FRANKFURT — Daimler and Geely on Friday said China could emerge as a manufacturing and export hub for hybrid powertrains jointly developed for Volvo and Mercedes-Benz cars. Earlier this week, Daimler said it would cooperate with China's Geely to build next-generation combustion engines for use in hybrid vehicles. The engines will be produced in China as well as in Europe, and Geely and Daimler will cooperate in engineering, sourcing and production, the companies said in a joint press release. "The export of the engine from China is considered to be an option," the release further said. Mercedes-Benz aims for more than half of its passenger car sales to be comprised of plug-in hybrids or purely electric vehicles by 2030. Geely is ChinaÂ’s most internationally known automaker. It owns Volvo Cars and Lotus, almost half of Proton and 9.7% of Daimler. Through wholly owned company Polestar, it builds low-volume Polestar 1 hybrid performance cars in the western city of Chengdu and Polestar 2 volume sedans in Taizhou in the east. "The companies plan to develop a highly efficient modular engine," a spokesman for Daimler said, adding that it would be used in hybrid drivetrains and manufactured in Europe and China. The modular engine will be used in cars under different marques at Geely and Daimler, a person familiar with the matter said on condition of anonymity as the companies are still in the early stages of developing the engine. An Conghui, President of Geely Holding Group, President and CEO of Geely Auto Group said: “This project reflects the need for economies of scale and targeted research and development investment in clean and highly efficient powertrains and hybrid drive systems and their applications." Geely also plans to build a plant with annual manufacturing capacity of 30,000 premium EVs in the western city of Chongqing, run by a wholly owned, newly registered company, according to documents on its website. Geely and Polestar declined to comment. The plan comes as foreign automakers including BMW AG and Tesla expand EV production in the worldÂ’s biggest market, sourcing major EV components such as batteries locally and often even exporting a portion of the vehicles it builds.   Auto News Earnings/Financials Green Plants/Manufacturing Mercedes-Benz Volvo Green Automakers Future Vehicles Hybrid
