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.

Mercedes could make EV batteries with Audi, BMW

It's not a big leap from digital maps to batteries, it turns out.The head of Mercedes-Benz parent Daimler said recently that he envisions his company working together with German automotive competitors BMW and Volkswagen to further accelerate electric-vehicle battery technology. The three automakers recently worked together to enhance their in-car maps systems. Daimler CEO Dieter Zetsche talked about "commonalities" between automakers, not the least of which is the need for all of them to achieve increasingly stringent fuel-economy requirements in the European Union, at the Frankfurt Auto Show last week, according to Reuters. While these companies have made their own inroads as far as plug-in vehicles go, they are all behind the Renault-Nissan Alliance when it comes to public deployment of electric vehicles. This summer, Daimler, Audi and BMW hooked up to acquire the Nokia Here digital-mapping service for about $2.8 billion. The triad of automakers beat out companies such as Apple and Uber to buy the entity, which was founded in 1986 as Navteq. Nokia bought the company in 2007. The acquisition makes sense as the automakers work on improving their products with features like cloud-based data to warn drivers of icy roads and traffic jams. The technology will likely also eventually be used in autonomous vehicles. Automakers working together for a common goal of improved technology is nothing new, of course. General Motors and Honda agreed in 2013 to work together to accelerate hydrogen fuel-cell drivetrain development. Earlier that same year, Daimler said it would work with Ford and Nissan in a separate collaboration to speed up the development of hydrogen fuel-cell technology. Related Video:

Recharge Wrap-up: BMW i8's Engine of the Year, biodiesel producer guilty

BMW has won International Engine of the Year for the hybrid system in the i8. The i8 PHEV uses a 1.5-liter, three-cylinder gasoline engine with a hybrid drive unit including a 96-kilowatt electric motor. BMW beat Ford's 1.0-liter EcoBoost engine by a small margin to win the award for best overall engine. It also took the award for the 1.4-liter to 1.8-liter category, as well as best new engine. Tesla beat BMW to win the green engine category for the electric powertrain of the Tesla Model S.

The head of Audi powertain development is quitting as the automaker steps up electrification. Stefan Knirsch has worked at Audi since late 2013, and previously worked at Porsche as the head of quality management and engine development. Germany's Auto Motor und Sport magazine had reported that Knirsch was leaving Audi, which Audi confirmed without giving a departure date or saying if he would be working elsewhere. Audi has been feeling pressure from its competitor Mercedes-Benz, and has been working on improving its EV offerings and autonomous vehicle technology. Read more from Reuters. The owner of a biodiesel company has pleaded guilty to fraud. Philip Joseph Rivkin, aka Felipe Poitan Arriaga, took part in a scheme to defraud the EPA, falsely claiming to be producing millions of gallons of biodiesel. This allowed his company, Green Diesel, to receive renewable fuel credits and sell them to oil companies and brokers. "These crimes are a serious threat to an important program that helps combat climate change," says Cynthia Giles of the EPA. "Companies and individual managers should get the message that there are serious consequences for breaking the rules and undermining the integrity of this program." Rivkin faces over 10 years in prison and $51 million in restitution. Read more in the press release below.
