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.

2015 Malaysian F1 GP springs hot, humid surprises [spoilers]

In the two weeks since Australia both Mercedes and Ferrari spoke of the improved performance from their respective cars. In Malaysia, Ferrari showed it. Lewis Hamilton still put his Mercedes-AMG Petronas on pole position, but Sebastian Vettel got within two whiskers of the Brit, lining up second just 0.074 behind. Afterward, Vettel said Ferrari could win the race if everything went well. But in qualifying we didn't know how much of Ferrari's performance was truly down to the car and how much was down to the wet weather that struck near the beginning of Q2. The rain didn't hamper Nico Rosberg's run – the German said "I just didn't drive good enough" – and he took third spot in the second Mercedes-AMG Petronas. Showing what the Infiniti Red Bull Racing chassis can do when the power unit is working properly, teammates Daniel Ricciardo and Daniil Kvyat grabbed fourth and fifth. Whippersnapper Max Verstappen, in his second race, qualified in sixth with an excellent drive through the rain; just 0.030 behind Kvyat, he said he could have got fifth if he hadn't had a running problem with his brakes. Williams head of vehicle performance Rob Smedley said he wouldn't complain about Mercedes' advantage, but Felipe Massa has spent the whole season so far banging the alarm about Ferrari's pace. He says Williams has lost its straight-line advantage, part of the reason the first Grove car is back in seventh, while Valtteri Bottas is in eighth. Between them was Romain Grosjean in the Lotus, but he got dropped two positions for a pit-lane infraction in Q2, so he'll be tenth. Ahead of him is Marcus Ericsson in the Sauber, who would lead the charge to turn in another surprise for the Swiss team. But the real surprise came from the Scuderia Ferrari, who, on a bright, sunny day proved that they don't need to add water for race-winning pace. While Hamilton got made usual awesome start at the lights, Vettel channeled that other famous German Ferrari driver and immediately cut across the track to intimidate Rosberg, maintaining his second place position into the first turn. Arguably the race-winning move came three laps later at that same turn, when Ericsson plunged in too fast and swapped ends, beaching the rear of his Sauber in the gravel trap. The safety car came out when the recovery truck emerged to retrieve the Sauber, and nearly all of the front-runners took to the pits to swap out of the medium tires. Vettel, however, didn't.

Mercedes-Benz C-Class scores well in TUV lifecycle analysis

Mercedes-Benz drivers and treehuggers don't always go hand in hand, but, like a lot of other companies, the German automaker is looking to boost its green cred. This time, it's all about the car's lifecycle carbon footprint. The Daimler AG unit is using its new C-Class sedan as an example of how it's making progress in that department. Mercedes-Benz, citing the inspection authority TUV Sud, says the 2015 C-Class has a 10-percent lower lifecycle carbon footprint than its 2014 predecessor, based on driving about 125,000 miles over the life of the car. About 95 percent of the car (by weight) is recyclable, slightly higher than the average for most vehicles, and the model has upped its amount of recyclable materials up by 23 percent and increased its use of "natural materials" by 55 percent. Better aerodynamics also helps things out on the fuel-economy front, Benz says. Taking a longer view, the 2015 C-Class's carbon footprint is 28 percent better than the 2007 version that launched the vehicle line. The 2015 C-Class hasn't received a fuel-economy rating from the US Environmental Protection Agency, which tagged the 2014 C350 with a combined fuel-efficiency rating of 24 miles per gallon from its 3.5-liter 6-cylinder engine.

TUV Environmental Certificate: The new C-Class makes its mark with an exemplary life cycle assessment Stuttgart, Mar 28, 2014 The C-Class sets efficiency benchmarks for its class, helped by an intelligent lightweight concept, excellent aerodynamics and new, frugal engines. The neutral inspectors from the TUV Sud technical inspection authority have confirmed the high level of environmental compatibility of the new Mercedes-Benz C-Class. Besides a sensuous, clean-cut design, a top-class interior and a host of technical innovations, the premium saloon also boasts an exemplary life cycle assessment, which is why it has been awarded the Environmental Certificate in accordance with the ISO 14062 standard. Professor Dr. Herbert Kohler, Chief Environmental Officer at Daimler AG: "Our engineers have pulled out all the stops in an effort to lower fuel consumption while at the same time further accentuating the car's sporty character. By employing an intelligent lightweight design with a high proportion of aluminium, for example, it has been possible to make the new C-Class up to 100 kilograms lighter than its predecessor.
