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.

Range Rover versus Mercedes-Benz: Which makes a more appealing SUV?

From time to time — truth be told, all the time — the Autoblog staff enjoys a good debate on the merits and demerits of the cars and trucks we drive each week. This week, we spent some time in a brand-new Land Rover Range Rover Supercharged SUV, a model some of us think sits at the pinnacle of the luxury utility vehicle segment. Others disagree. The following is a real-life online debate that took place over the course of a few hours. Have a read, and feel free to take sides. There's a poll at the end so you can make your voice heard. Consumer Editor Jeremy Korzeniewski: Strange as it may sound, Jeremy Clarkson and I have a few things in common, most obvious of which is that we share a given name. But we also both love cars so much that we decided to turn our automotive passion into a career — with varying degrees of success, of course — and we both have come to realize over time that there's no point in trying to topple the Land Rover Range Rover as the world's best luxury off-road utility vehicle. Thing is, this universal truth isn't quite as universally shared as I think it should be. In fact, my esteemed colleague Alex Kierstein believes that Mercedes-Benz makes the most desirable four-wheel-drive off-road vehicles. He's clearly wrong, but I feel obligated to let him explain his choice, though it won't go without a rebuttal. Senior Editor Alex Kierstein: That's correct, and so am I in this regard. I'm sorry, Jeremy, but it's an irrefutable fact that Mercedes-Benz is doing the best interiors in the business now. And the interior is where you're going to spend most of your time, at least when the thing's running. The Range Rover's interior simply isn't as special, and frankly it'll be in the shop enough that you won't enjoy it. Now, stepping into pretty much any contemporary Mercedes sedan interior is a "wow" moment. They seem special — posh, exclusive, luxurious. The SUVs, all older vehicles coming due for total redesigns at some point in the future, are lagging a bit, but it's still a premium and upscale experience. Especially since performance is almost academic at this point. Anything in this class is going to be powerful, almost absurdly so. So why not go for the one that makes you feel like royalty, rather than your mechanic? JK: I just want to point out that it was you who brought reliability into this discussion.
