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.

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.

Luxury car brands scrambling to avoid a blue Christmas

DETROIT — When financial markets surge to new records, sales of luxury cars usually rise, too. Instead, October U.S. auto sales reports on Wednesday showed that a collapse in sales of luxury sedans is accelerating. Consumers have gradually shifted over to luxury sport utility vehicles from sedans in the past decade, but the trend — which has occurred in both the non-luxury and luxury sedan segments of the auto market — was particularly pronounced in October. Sales of Daimler AG's Mercedes-Benz S-Class, long a global benchmark for large, premium sedans, plunged 49 percent in October, and are down 24.8 percent for the year to date. General Motors' Cadillac brand said it sold just 779 of its CTS sedans in October. Demand for that car, designed to compete with German luxury sedans, is down nearly 33 percent for the year. "There's still a significant portion of the market that wants a car, but I'm sure there were people who preferred a horse to a car at one point." Cadillac's best-selling model this year is the XT5 compact SUV, which has more than doubled sales from a year ago. The shift within the luxury vehicle market away from sedans toward SUVs of all sizes is forcing some of the most prestigious brands to scramble to add SUV models to their lineups or boost SUV production to meet demand. "In the short term, there will be pressure to add (consumer) incentives, cut production or both," said Cox Automotive analyst Michelle Krebs. "And we just don't see an end in sight to this trend." The Dow Jones Industrial Average has been trading at all-time highs, usually a good sign for luxury sedans, but as major automakers reported new U.S. vehicle sales for October on Wednesday, sales for passenger cars continued their slide while luxury SUV and crossover sales rose again. According to Kelley Blue Book data, in 2007 luxury sedans made up 7.6 percent of U.S. new vehicle sales, while luxury SUVs made up 4.2 percent. Through September this year, luxury SUVs made up just over 7 percent of the market, compared with 4.9 percent for luxury sedans. In the short term, luxury brands could use holiday season sales promotions to clear slow-selling sedans off dealer lots, analysts said. Toyota's Lexus brand said on Wednesday it will launch its "December to Remember" year-end sales promotion for the 18th straight year.
