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.

Aston Martin signs Letter of Intent for technical partnership with AMG

A little over two months ago came reports that Daimler and Aston Martin were in talks, again, about "supply and technical-cooperation agreements." The next step has been taken with Aston Martin announcing that it has signed a Letter of Intent that looks "towards a technical partnership" with Mercedes-AMG GmbH, and the two companies aiming to have definitive agreements done by year's end.
While it will get to use certain electric and electronic components from AMG, the true golden egg for the maker of the Vanquish will be the ability to develop a new line of "bespoke V8 powertrains" that will be fitted to "a new generation of models." In return for opening up the larder, Daimler will get a non-voting stake of up to five percent of Aston Martin.
Nothing else is being said about the tie-up for the moment, but there's a press release below with a few more details.

Porsche teams with Delta airlines to woo VIP passengers

The next time you're waiting for a flight at Hartsfield-Jackson Atlanta International Airport, see if you can spot a Porsche Cayenne or Panamera zipping between aircraft on the busy tarmac. The high-performance German vehicles aren't there practicing for an upcoming autocross; they are tasked with whisking some of the airline's most important customers between flights so they can keep their busy schedules intact.
Launched nearly two years ago, the program has proven popular with the automaker, airline and passengers as all benefit from the unique arrangement. Atlanta-based Porsche is able to showcase its cars to Delta's frequent-flying Medallion members, the airline is recognized for providing unusual perks to its high-value customers and those fortunate enough to be surprised with a quick lift are able to make connections without a stressful run through the terminal. Based on its success, the airline is rolling our similar programs in New York, Los Angeles and Minneapolis this month.
And don't think Porsche is the only automaker working with an airline to entice its frequent flyers. Mercedes-Benz ran a program over the summer that offered purchasing and leasing incentives to MileagePlus Premier members of United Airlines, and the two are currently shuttling top fliers around Houston's George Bush Intercontinental Airport in the automaker's S-Class and GL-Class models.
