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.

Daimler chairman agrees with German Greens on reducing emissions

Daimler Chairman Dieter Zetsche spoke at a Green Party congress in Germany earlier this week and said he agreed with the party's urge to dramatically cut transportation-based greenhouse-gas emissions by expanding plug-in vehicle sales, Reuters says. Zetsche stopped short of backing the Greens' suggestion to ban gas- and diesel-powered vehicles by 2030, though. The man must keep his job, after all. Zetsche did say that reducing greenhouse-gas emissions from the transportation sector was "necessary," and his company has made plans to do just that. Daimler representatives said at the Paris Motor Show earlier this year that Smart and Mercedes-Benz both planned to debut more than 10 electric vehicles within the next decade, and that plug-ins may account for as much as 25 percent of Mercedes-Benz's sales by then. Moreover, Dr. Thomas Weber, Head of Group Research and Mercedes-Benz Cars Development, said in June that Mercedes could be selling as many as 100,000 EVs a year by the end of the decade. Last month, Mercedes-Benz announced that its EQ electric-SUV concept would go on sale by 2020, and that the Bremen factory that's producing the model will broaden its plug-in vehicle production further. Zetsche's cautious support notwithstanding, the German government appears to be doing its own part to reduce emissions from the country's light-duty vehicles. Earlier this year, Germany enacted a plan that provides as much as 4,000 euros ($4,270) in perks for people who buy new electric vehicles, with German automakers agreeing to foot about half of the estimated $1.4 billion bill. German lawmakers had also floated the idea of a 10-year moratorium on electric-vehicle taxes for cars purchased before 2020.

McLaren, Red Bull and Ferrari call for unfreezing F1 engines

Formula One is a hugely expensive sport. Not only do you have enormous salaries and logistical expenses, as you would in any other sport, but each team also spends huge sums developing their own chassis from the ground up – and so too do the participating automakers in developing the engines. One of the ways the series organizers mitigate those costs is by freezing development. So once the new crop of V6 turbo hybrid powertrains were developed, that was it. But now three of the of the sport's leading teams are calling on the FIA to unfreeze engine development. Their reason? Unfair advantage. There's little question that Mercedes did the best job of developing its "power unit" to meet the new regulations that took effect at the beginning of this past season. That's how the Mercedes team won all but three of the grands prix this season and finished with at least one car on the podium at every single race. It's also a big part of how the teams that bought their engines from Mercedes this season managed to consistently outperform the other non-works-supported teams. That clear advantage is why Red Bull, Ferrari and now McLaren are calling for engine development to be unfrozen. Their argument is that, under the current locked-down status quo, their engine suppliers (Renault, Ferrari and Honda, respectively) cannot possibly catch up. So unless the FIA and Formula One Management want the next few seasons to be the kind of absolute blow-outs that this past season was, these leading teams argue, the powers that be are going to have to make some changes. For its part, Mercedes naturally counters that unfreezing engine development would send costs spiraling out of control. But then of course it stands to lose the most by re-opening engine development. If those three teams, however, closely intertwined as they are with the three other engine suppliers participating in next year's championship, manage to solicit enough support from the other customer teams and bring the matter to a vote, Mercedes may very well find itself out-numbered.
