Mercedes-Benz GLK coupe to get 2016 intro

Radio chatter around the emerging small, premium crossover coupe genre has thus far been dominated by the Land Rover Evoque and the Mini Paceman. According to a report in Car, the Mercedes-Benz GLK-Class (shown above) has received its invitation to the party and will spend the next three years getting ready: it's said that two-door variant of the crisply-angled CUV is coming in 2016, along with a redesign befitting its sleeker intentions.
To be based on the MRA platform - the rear-drive version of the company's three new modular platforms, it will also support the coming 2013 S-Class and could eventually get an AMG version to help it compete with segment offerings like the forthcoming Porsche Macan. Not much else is known about it beyond its name: Car says it will be called the GLC, a friendly nomenclature we remember best as a Mazda hatchback (allegedly for "Good Little Car"). Internet oldtimers may remember the Mazda GLC as the predecessor to the 323 (which in turn came before today's Mazda3). Either way, the GLC is not to be confused with the larger upcoming BMW X6 rival based on the ML-Class (reportedly called GLS) which is also said to still be in the works, or the front-drive based GLA, a model also edging toward production.

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.

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.
