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.

Autoblog fan favorite car ads from Super Bowl XLIX

Super Bowl XLIX is in the books, and the New England Patriots emerged victorious. Of course, if you're like us, the big game wasn't so much about the battle between the east coast and west, so much as a fight between the world's automotive advertisers. We collected and collated all of last night's new ads and put them together for you to vote on. And yes, we're limiting this year's contest to last night's new features. That's why you aren't seeing Dodge's epic Wisdom among our collection of commercials, and it's a similar story with Chevrolet's Truck Guy Focus Group series, which highlights the new Colorado. You can still vote for your favorites. We won't be closing the voting on our Super Bowl page, so while the winners and losers are correct as of this writing, it's entirely possible that there could be some changes in the rankings as time goes on. So, without any further ado, here are the winning ads based on your voting. Nissan: With Dad Fiat: Ready For Action Jeep: Beautiful Lands BMW: Newfangled Idea Mercedes-Benz: Fable NASCAR: America Start Your Engines As for those ads that failed to impact you, loyal readers, Toyota was the absolute, undisputed loser. The Japanese brand ran four ads in total – two for Toyota and two for Lexus – and all of them have negative tallies as of this writing. Lexus' Make Some Noise and Lets Play and Toyota's One Bold Choice and My Bold Dad both had very weak showings among the commercials that aired, although they weren't alone. Neither Mazda nor Kia scored particularly well, despite featuring celebrity magic act Penn and Teller and former James Bond, Pierce Brosnan, respectively. Chevrolet was the winner of the losers, as of our writing, recording the fewest downvotes for its audience-punking The Big Game ad. If you want to take a second look at the losing ads, you can head back to our Super Bowl page for the complete collection. But for now, head into Comments and let us know what you think of the results.

Geely chairman is now the single biggest investor in Daimler

Li Shufu, the chairman and main owner of Chinese carmaker Geely, has built a stake of 9.69 percent in Daimler AG, the German carmaker said in a regulatory filing on Friday. The stake, worth nearly $9 billion at the current valuation for Daimler shares, makes Li the biggest single shareholder in the maker of Mercedes-Benz cars, trucks and vans headquartered in the German city of Stuttgart. A Daimler spokesman called the stake purchase a private investment by Li. "We are delighted, with Li Shufu, to have won over another long-term investor who is convinced of Daimler's innovative prowess, strategy and future potential," the spokesman said in response to a request for comment. "Daimler knows and respects Li Shufu as a Chinese entrepreneur of particular competence and forward thinking." Li's stake purchase makes him the top shareholder in Daimler ahead of the Kuwait Investment Authority, which owned 6.8 percent as of Sept. 30, according to Thomson Reuters data. Earlier this month, the German newspaper Bild am Sonntag reported that the Chinese industry giant was seeking to become Daimler's biggest shareholder, likely exceeding the 6.8-percent stake of the Kuwait Investment Authority. The paper said Daimler had reportedly turned down Geely's $4.5 billion offer for a 5-percent stake via a discounted share placement, saying that Geely could buy shares in the open market. Institutional investors currently own 70.7 percent of Daimler, and the company already has strong ties to Chinese automakers BAIC and BYD. Bild am Sonntag said the move was intended as a strategic alliance against Apple, Google and Amazon on autonomous and connected cars. And Reuters reported that Daimler wants to have bespoke "robo taxis" on the road quicker than Google's Waymo, and views Geely as a strong partner for that. Geely conversely is interested in Daimler's electric car battery technology, and sources quoted by the German paper say there are plans to establish joint electric car manufacturing in Wuhan, China, to meet China's smog-reducing quotas. Geely is developing the Lynk & Co. brand of electric and hybrid cars. Geely owns Volvo, which has enjoyed a renaissance under the arrangement, as well as the maker of London's black cabs. In December, it bought a stake in AB Volvo, the maker of Volvo trucks.
