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.

Maybach officially discontinues all models for 2013

The word "Maybach" has joined the long list of synonyms for the word "kaput." Mercedes-Benz released the price list for the 2013 models of its super-luxury sedans, with the price column simply stating "Discontinued" for each one of them.
The 2012 models, should there be any left for 11th-hour buyers, maintain the increased MSRPs that Daimler slapped on them late last year after it was known the brand would be terminated next year. But you might still be able to wrangle that $100,000 rebate if you ask nicely, or in Russian, or have Rick Ross ask for you.
It shouldn't be too long before we see the ultimate version of the next generation S-Class, the S600 Pullman, that will replace Maybach. Intriguingly, it's said the Pullman will be offered with every S-Class engine, even the four-cylinder diesel.

Infiniti shows Q30 interior ahead of Frankfurt debut

Infiniti is supposed to debut the all-new Q30 hatchback at the 2015 Frankfurt Motor Show, but as the show is still a couple of weeks away and the company has elected to release yet another image, we aren't sure there'll be all that much to see come Sept. 15. With that in mind, then, we give you the first images of the entry-level hatch's cabin, and they're, um, wow. We knew the Q30 had a lot in common with the Mercedes-Benz A-Class but as these images show, this is far more than a common platform. The steering wheel, instrument cluster, switchgear, and shifter are direct from the Mercedes parts bin. From the looks of the images, the Q30 will even have a Mercedes-style key. This might not garner much attention in the budget ranks – take the Scion iA and Mazda2, for example – but this degree of parts sharing in the premium market is sure to raise some eyebrows. It's also a rather bewildering move for Infiniti. The company is, in effect, selling a Mercedes-Benz to any new customers it attracts. That'll certainly make a Q50 a hard sell when it comes time for an upgrade. Now, in Infiniti's defense, there are some differences in the layout here. The triple nozzle-style HVAC vents have been replaced with a more conventional pair of outlets, and the instrument cluster hood extends over the built-in navigation screen. That design decision, in particular, will certainly appeal to critics of the tacked-on-tablet look offered by Mercedes. The analog buttons for the multimedia system have also been tweaked, with the result looking far cleaner than the mess of buttons offered on Mercedes' products (we wouldn't be shocked to see this layout arrive on a facelifted A-, CLA-, or GLA-Class in the near future, though). Beyond those changes, though, there are multiple Mercedes design hallmarks here, including the location of the controls for the seat adjustments. You can check out the Q30's cabin in both right- and left-hand drive varieties courtesy of the images above. And for comparison's sake, we also included our most recent gallery of the Mercedes-Benz GLA-Class at the bottom of the page. Have a look and be sure to scroll down for the official press release.
