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.

Red Bull may seek engines from Ferrari after Mercedes snub

Red Bull and Renault's fractured relationship is pushing the Austrian F1 team to find a new engine provider. But after a trip across the German border to chat with Mercedes-Benz proved fruitless, the team is apparently set to head across its home country's southern border, and into Italy. Yep, Red Bull Ferrari could be a thing next season. According to RBR boss Christian Horner, the company is just doing "necessary due diligence" in contacting other engine suppliers, although he's willfully admitted to Germany's Bild newspaper that the "idea of Mercedes is finished," BBC Sport reports. It wasn't so much that Mercedes and Red Bull couldn't come to financial agreement – Red Bull owner Dietrich Mateschitz views throwing money into F1 in much the same way you or I toss pennies into the mall fountain – but rather that the Germans had no interest in supplying the best engines on the grid to the factory team's perennial rival. BBC Sport seems to think that fact, along with what the outlet calls Red Bull's "antagonistic" relationship with engine suppliers, killed the Mercedes deal. Honda and RBR aren't likely to happen either, thanks to McLaren (not that we think Red Bull would approach the Japanese, which have struggled mightily all season long). By process of elimination, that just leaves Ferrari. Scuderia Ferrari Team Principal Maurizio Arrivabene confirmed that his team can accommodate Red Bull's engine needs, and that he wasn't concerned with the idea of a Ferrari engine in an Adrian Newey-designed body. "In theory they have big names, with Newey as chief designer and it is easy to think that if you give them the engine they will build a scary chassis, which means they will be really competitive," Arrivabene told BBC Sport. "Concerning my team, my engineers and aerodynamicists know their own jobs. For that reason I don't have a problem, and competition is nice when you have a stronger competitor." "This doesn't mean tomorrow morning we will give our engines to Red Bull or Toro Rosso," Arrivabene added. And it's that statement we'd suggest remembering. There are, after all, still seven races left in the 2015 season, which is quite a lot of time for new and different developments within the sport's notoriously gruesome political process. In other words, don't count on an announcement from any team or manufacturer for at least a few more races. Related Video:

Daimler boss says fuel cell vehicles will be disappointing for at least 10 years

Daimler AG CEO Dieter Zetsche is pretty confident about the imminence of self-driving cars. Hydrogen fuel-cell vehicles? Not so much. He didn't even get into the possibility of self-driving fuel-cell vehicles, but we're okay taking future technologies one at a time. Zetsche, in an interview from the Detroit Auto Show last week, said the automotive industry is about a decade away from avoiding disappointing experiences with production fuel-cell vehicles, In Auto News says. Zetsche was quick to note that the Mercedes-Benz parent entered into a fuel-cell partnership with Ford and Nissan early last year in an effort to split costs and speed things along, with the expectation that the group would develop something together by 2017, but even that won't be able to smooth things out fully. Toyota and Hyundai have said they'd have their own production vehicles on the road sooner than that. Multi-corporation-partnerships notwithstanding, Zetsche bemoaned the high costs, lack of vehicle volume and minimal refueling infrastructure as the proverbial roadblocks to more rapid development and adoption of fuel-cell vehicles. As it is, the US has just 10 publicly accessible hydrogen refueling stations, eight of which are in Southern California, according to the US Department of Energy. As for autonomous automobiles, Zetsche was more upbeat. Daimler already has what it calls the "Distronic" cruise control system that includes an automatic braking feature and has successfully driven a car 60 miles with "with relatively modest adjustments to the existing onboard technology."
