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.

This or That: Mercedes S-Class 350SD vs. 2003 Jaguar XJR [w/poll]

Budget. It's a wretched word, whether you're going out to eat, shipping for a new outfit or, more relevant to today's discussion, buying a car. Massive marketing machines have convinced us, as a population, to buy the best you can afford, repercussions be damned – If you've saved up some money, spend it! All of it, on whatever it is that currently sits atop your personal Amazon wishlist, be it a Timex that takes a lickin' and keeps on tickin', a $17,000 Gold Apple Watch or a $60,000 Rolex Cosmograph Daytona. But what if the best you can afford is... say, $12,815? For that price, you can buy a brand-new 2015 Nissan Versa (including destination), assuming you're happy with zero options and a manual transmission. For that price, you'll get standard air conditioning, a CD player and... well, a warranty. Pretty sensible choice, Captain Frugal. But also ridiculously uninspired. And so that brings us to today's edition of This or That, in which two Autoblog editors pick differing sides of an argument and duke it out to see which one of us can convince you, dear reader, is better. Or at least less wrong. You be the judge. As a refresher, I'm two-and-two on these challenges, having lost the first and second editions before storming back in rounds three and four. Today, as alluded to above, we decided to throw our collective brainpower (oh lord, what have we done?) at what may be the single most difficult question currently confounding the best minds our planet has to offer: What is the best used used luxury car you can buy for the price of a 2015 Nissan Versa? Shall we meet our contenders? Allow me to introduce you to the most perfect luxury car money can buy (assuming the amount of money you're holding is equal to the amount of the cheapest new car currently sold in America, the Nissan Versa). My pick is the 1991 Mercedes-Benz S-Class. Not just any S-Class, but the legendary W126, which was produced between 1979 and 1992. And not just any W126, either, but one powered by a 3.5-liter turbodiesel engine. And with that, I send the argument to my esteemed colleague, Associate Editor Chris Bruce. Bruce: Jeremy, we had over $12,000 to budget for this challenge, and the best you can manage is a 24-year-old diesel Mercedes? I love oil-burners as much as any other auto writer with their mountains of torque and huge cruising range, but you're making this too easy on me. Also, you're really choosing a brown, diesel, German luxury sedan?

Brabus 800 Roadster is a power-mad aristocrat

If we're being completely honest, we haven't exactly been in love with the aesthetics of the sixth-generation Mercedes-Benz SL-Class. It's mostly a front-end issue, with its glowering eagle-eye headlamps and upright, dinner-plate-sized Three-Pointed Star coming across to us as overwrought. That's particularly troublesome for a roadster whose history has of the most elegant designs of all time in its back catalog. Somehow, the new R231 generation's brash visuals seem more at home on this Brabus 800 Roadster to us.
That's probably because the high-dollar German tuner has turned up the wick on the SL's visuals even further, with carbon fiber bodywork, a more aggressive aero kit, matte hood scoop and complex two-finish wheels. It's all-the-way committed to its brashness, in other words - and justifiably so. Anything with 800 horsepower and 1,047 pound-feet of torque has earned the right to look however it wants, right?
Brabus started with the SL65 and its not-exactly-underpowered 6.0-liter twin-turbo V12, and went to town, fitting their own turbocharger and intercooler system, along with a less-restrictive exhaust system with driver-selectable sound levels and new engine electronics. The result is a 3.7-second 0-62 mph time, an electronically limited top whack of 217 mph... and one seriously compromised toupée.
