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.

2017 Aston Marin Lagonda could live on Mercedes M-Class platform

A few weeks ago, we brought you news from the launch of the Aston Martin Vanquish Volante that the British brand, which is formally known as Aston Martin Lagonda, was still planning on going ahead with a Lagonda-badged crossover. Now comes word that that vehicle could very well be based on a Mercedes-Benz M-Class.
When the first Lagonda Concept debuted at the 2009 Geneva Motor Show, it sat on a Mercedes-Benz GL-Class platform, some four years before Aston Martin and Mercedes-AMG deal was inked. And with that partnership, which will see Aston Martin gain access to AMG electrics and "bespoke, V8 powertrains," the opportunities for platform sharing are many.
Dr. Ulrich Bez, the boss of Aston Martin, told the UK's AutoCar, "I look at what Porsche is doing with the 911 as its core business and then it is able to do models like the Cayenne based on the Volkswagen Touareg. It is good business." We've said many times that we'll tolerate exotic CUVs and SUVs if it means keeping the beloved core models alive, which has been the case with Porsche. We see no reason Aston Martin wouldn't be able to do the same.

Autoblog drives to the Arctic Circle

In Which Mercedes' Sprinter Becomes A Long-Distance Sherpa
In the wintery wilds of northern Alaska, even the cute little critters want to kill you.
As I am about to nod off on my long leg flight from Minneapolis to Anchorage ahead of driving to the Arctic Circle, the friendly twenty-something Alaskan knitting furiously in the seat next to me pauses and says, "When you're driving up there, don't open your windows." In the dead of winter? I hadn't planned on cruising alfresco, but her warning to keep the glazing snugged against the weatherstripping is one I would take to heart. She continues: "If you leave 'em open, a fox is liable to jump right in. There are lots of rabid foxes up there, and they leap into your car and just Go. To. Town." And here I was, thinking that a curious bear or maybe an ill-placed moose in the road was going to be my biggest potential four-legged threat. In the wintery wilds of northern Alaska, even the cute little critters want to kill you.
