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 names Bernd Pischetsrieder to supervisory board

Some executives in the automotive industry stay with one company for their entire careers, while others bounce from one to the other, often leaving their indelible mark on each automaker at which they serve. Bob Lutz is certainly an example of the latter. So is Lee Iacocca, having presided over Ford and later charing the Chrysler board. Carlos Tavares was chief operating officer of Renault before being nominated as chief executive at PSA Peugeot Citroën. But as far as the Germans go, nobody's jumped from the leadership of one automaker to the next quite like Bernd Pischetsrieder - especially now that he's been named to the supervisory board of Mercedes-Benz parent company Daimler.
An engineer by training, Pischetsrieder started his career at BMW in 1973, eventually rising to the office of CEO after twenty years. There he remained until 1999, only to be dismissed after orchestrating BMW's takeover of the Rover Group (of which only the Mini brand remains in the company's portfolio, the other brands having been sold off after his dismissal).
The next year he was named chairman of Volkswagen's Seat brand, and rose to the chairmanship of the entire Volkswagen Group two years later. Despite a largely successful four-year tenure (that gave birth, incidentally, to the Bugatti Veyron), disagreements with supervisory board chairman Ferdinand Piëch saw him leave the helm at VW AG, focusing his attention on the Scania truck division. He's since been touted as a potential chief executive for Opel and for Continental, but neither potential was apparently realized.

Next Mercedes S-Class stretching into this 600 Pullman limo

To the concern of nobody in particular, Mercedes-Benz will not be re-upping its Maybach line of ultra-luxury limousines. No, instead the German automaker will be stretching its already roomy S-Class, to make this upcoming 600 Pullman version of the decked-out beast.
The car in our new gallery of spy shots is sporting beefy B-pillars and a massive set of rear doors that should allow perfectly graceful ingress and egress from what is likely to be a palatial rear space. (In one photo we can even see a long-wheelbase S-Class in line with the new Pullman, handily exhibiting the size of the new variant.) The exterior modifications are otherwise obscured, though we can guess at revised front and rear fascia and lighting elements, based on both end being heavily taped for these test runs.
It's a good bet that the Pullman will make use of M-B's twin-turbocharged V12 engine, though sources indicate that a hybrid version might eventually be in the offing, as well.
