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.

Weekly Recap: Toyota propels hydrogen fuel cells

Toyota is serious about hydrogen fuel cells, and it wants the auto industry to follow suit. The Japanese automaker said this week it's releasing 5,680 fuel cell patents from around the world, including technologies used on its upcoming sedan, the 2016 Mirai. The move is unusual, but not unprecedented, as Tesla similarly released its electric vehicle patents last year. The idea for Tesla, and now for Toyota, is to spur development of alternative propulsion. "By eliminating traditional corporate boundaries, we can speed the development of new technologies and move into the future of mobility more quickly, effectively and economically," said Bob Carter, Toyota Motor Sales senior vice president of automotive operations, in a statement. Toyota's fuel cell patents will be free to use through 2020, though patents related to producing and selling hydrogen will remain open forever. Toyota said it would like companies that use its patents to share their own hydrogen patents, but won't require it. "What Toyota's doing is really a logical move, and really a good move for the industry," Devin Lindsay, principal powertrain analyst with IHS Automotive, told Autoblog. The announcement was made at the Consumer Electronics Show in Las Vegas. It comes as Toyota prepares to launch the hydrogen-powered Mirai in a limited number late this year in California. The launch will be extended to the Northeastern United States next year. Toyota also has announced plans to support networks of fueling stations in each region to try to smooth consumer adoption. The Mirai has a 300-mile range on a tank of hydrogen, and it takes about five minutes to refill. Fuel cells have been receiving increased attention recently, and Audi and Volkswagen debuted hydrogen-powered cars at the 2014 Los Angeles Auto Show. Honda, another proponent of the technology, also showed its updated FCV concept in November in Japan. The company, however, has delayed its fuel cell sedan a year until 2016. Like Toyota, Honda says its hydrogen-powered car will have a range of 300 miles or more. Meanwhile, Hyundai currently offers leases for fuel-cell powered Tucsons, which have a 265-mile range, in Southern California. Despite the optimism some automakers have for fuel cells, the technology still faces barriers. A lack of filling stations has long held it back, and many consumers are not familiar with the potential benefits.

Mercedes-Maybach rolls out new S, GLS and EQS SUV Night Series

Mercedes-Maybach is embracing a new look for what it hopes will be a new generation of buyers — one keen to embrace its new electrified luxury models. The new Night Series will be offered on all three models in the current Maybach lineup, with the S-Class and EQS SUV variants arriving later this year and the GLS following in early 2024. While the execution off each Night Series is dependent on the model in question, they share a few common elements. Their headlights, for instance, are all embellished with dark chrome Maybach logos on rose gold trim. You'll find that dark chrome just about anywhere you'd normally spot bling, from the grille and exterior trim to the coating on the rear exhaust finishers. And then there are those wheels. I don't know what to say, quite honestly. Just look at them. And while you're at it, peep at the running boards on the EQS SUV.  While the cars shown here are quite uniform, differentiation will come in the form of finish choices and further individual customization. All three are offered with the Obsidian Black/Mojave Silver two-tone combination shown here. The EQS SUV will also be available in Obsidian Black and Manufaktur Diamond White finishes, the S-Class can be done up in various grey, black and white hues, and the GLS can be had in white or Obsidian Black.  Inside you'll find herringbone-patterned, open-pore wood with aluminum accents along with another smattering of dark chrome. The EQS SUV and GLS can optioned with with Nappa leather in two-tone Crystal White/Black Pearl or just plain Black Pearl. In the S-Class, you can do Nappa leather in either Deep White/Black Pearl or straight Black Pearl.  Look for more on the Mercedes-Maybach S-Class and EQS SUV Night Series soon, with more to come on the GLS variant as its arrival draws closer.  Related video: 2022 Mercedes-Maybach S 580 walkaround
