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.

A car writer's year in new vehicles [w/video]

Christmas is only a week away. The New Year is just around the corner. As 2014 draws to a close, I'm not the only one taking stock of the year that's we're almost shut of. Depending on who you are or what you do, the end of the year can bring to mind tax bills, school semesters or scheduling dental appointments. For me, for the last eight or nine years, at least a small part of this transitory time is occupied with recalling the cars I've driven over the preceding 12 months. Since I started writing about and reviewing cars in 2006, I've done an uneven job of tracking every vehicle I've been in, each year. Last year I made a resolution to be better about it, and the result is a spreadsheet with model names, dates, notes and some basic facts and figures. Armed with this basic data and a yen for year-end stories, I figured it would be interesting to parse the figures and quantify my year in cars in a way I'd never done before. The results are, well, they're a little bizarre, honestly. And I think they'll affect how I approach this gig in 2015. {C} My tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015 it'll be as high as 73. Let me give you a tiny bit of background about how automotive journalists typically get cars to test. There are basically two pools of vehicles I drive on a regular basis: media fleet vehicles and those available on "first drive" programs. The latter group is pretty self-explanatory. Journalists are gathered in one location (sometimes local, sometimes far-flung) with a new model(s), there's usually a day of driving, then we report back to you with our impressions. Media fleet vehicles are different. These are distributed to publications and individual journalists far and wide, and the test period goes from a few days to a week or more. Whereas first drives almost always result in a piece of review content, fleet loans only sometimes do. Other times they serve to give context about brands, segments, technology and the like, to editors and writers. So, adding up the loans I've had out of the press fleet and things I've driven at events, my tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015, it'll be as high as 73. At one of the buff books like Car and Driver or Motor Trend, reviewers might rotate through five cars a week, or more. I know that number sounds high, but as best I can tell, it's pretty average for the full-time professionals in this business.

Audi considers a rugged SUV — maybe on the Scout platform

Audi engineers are formulating plans to possibly build a “super saloon” luxury off-roader SUV in 2027, It would compete in a segment that now includes the Land Rover Defender and Mercedes-Benz G-Class, according to a report in BritainÂ’s Autocar. According to Audi designer Marc Lichte, quoted in the story, the platform for the new model could be borrowed from the Volkswagen GroupÂ’s recently announced sister brand, Scout Motors, which is currently developing electric-powered concepts and prototypes. While Audi has developed a PPE (Premium Platform Electric) architecture for its base EV lineup, that would be replaced in the planned model with ScoutÂ’s ladder chassis to provide the steep departure angles and ground clearance needed to negotiate tough terrain, as well as with the latest generation of AudiÂ’s Quattro four-wheel-drive technology, Autocar reports. Audi is well into development of its Activesphere project, an enticing design blend of coupe and hatchback. The Activesphere uses PPE, co-developed by Audi and Porsche, and will appear in a production Audi product by the end of this year. Audi says. Beyond that, “I think there is space" for a rugged SUV in AudiÂ’s passenger car lineup,  Lichte said. “There is potential because there are only two premium players” in this particular segment" (Mercedes-Benz and Land Rover) “and I think there is a space for a third one.” The upscale Defender was by far Land RoverÂ’s best-selling car last year, with 66,805 sold, and the G-Class set a new sales record the previous year with 41,174 moved worldwide. Audi obviously would like to capitalize on this popularity of the rugged 4x4 segment. The proposed competitor, said Lichte, “will not look like a G-Class and it will not look like a Defender, I can promise you. It will be something else."
