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.

Hyundai plans Level 4 autonomy by 2021 in a fuel-cell car

SAN FRANCISCO — Silicon Valley startup Aurora announced on Thursday partnerships with Volkswagen AG and Hyundai to develop a self-driving system within their vehicles, the latest tie-up between global automakers and Silicon Valley tech companies. Aurora was founded in 2016 by robotics expert Drew Bagnell, Chris Urmson, who came from Alphabet Inc's Google, and Sterling Anderson, who formerly worked at Tesla. For Hyundai, Aurora's technology will be incorporated into custom-developed models and tested in markets including China. Hyundai said the first model to be used in testing will be its latest generation fuel-cell vehicle, debuting at the CES technology conference in Las Vegas next week. The model name of the car, shown above, will be announced then. Under the alliance, Hyundai plans to commercialize level 4 autonomous vehicles — which can operate without human input or even human oversight under select conditions — in unidentified "pilot smart cities" by 2021. This is the first announcement on a self-driving technology partnership by the South Korean carmaker, which has traditionally shunned tie-ups in favor of developing technology in-house. The strategy has raised investor concerns that it may be left behind in the race for self-driving and electric cars. A company spokeswoman said Hyundai has "various collaborations" under way in self-driving technology and would continue to pursue cooperation. In a statement, Volkswagen said Aurora's self-driving technology can be integrated over time across the automaker's brands and in different product categories, whether self-driving pods, shuttles, delivery vans or self-driving trucks. Aurora and Volkswagen said they had been working together over the past six months to integrate Aurora's sensors, hardware and software into the German carmakers' electric vehicles to develop self-driving ride services in cities. The non-exclusive partnerships mark the first deals for the young Silicon Valley company and show how some carmakers have chosen to partner with technology companies with more experience in artificial intelligence, deep learning and robotics in order to save time and money bringing self-driving cars to market. Within the self-driving car space, Waymo — formerly Google's autonomous program headed by Urmson — is offering something similar. The tech company has been working with Fiat Chrysler since 2016 to outfit its Chrysler Pacifica minivans with autonomous technology.
