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.

2015 Mercedes-Benz CLS400 [w/video]

Rocky IV debuted in 1985 but it was a few years later that I first watched it, on video. I loved every second of that terrible movie. I loved Drago's super-high-tech demonstration of punching power. I loved Rocky training in a Russian barn, with ropes, and yokes, and wagons. But mostly I loved Brigitte Nielsen. My 10-year-old brain sweated her impossible combination of curves and sharp edges, demure eyes, and sculpted bone structure. The perfect woman, but evolved by the power of the dark-hearted Soviet Union (or Denmark, whatever, I was ten). Red Sonja has a lot in common with the latest version of the Mercedes-Benz CLS, as I see it. Mercedes created a new market niche with its first four-door coupe, a sedan so well-proportioned, flowing, and femininely curved that it could pull off its inaccurate moniker. The third evolution of the CLS you see here has Nielsened up the shape into something altogether more angular and edgy, but like 1985's Brigitte, retains an undeniable sex appeal. It's a more opinionated piece of auto design than was the original CLS. And also a car that bifurcates the space between luxury coupe and luxury sedan. Ludmilla Drago would undoubtedly understand. Driving Notes For the base engine of a 4,200-pound car, the CLS400's two-turbo V6 does better than just get out of its own way. The full 354 pound-feet of torque is available way down at 1,600 revs, and plateaus until 4,000, giving you a fat band in which to call up power. Acceleration is available in the form of a quiet, gracious, but not aggressive push at just about every speed. From inside the cabin, the engine and exhaust noises are pleasantly rumbling, though muted. But do yourself a favor and try not to listen to the CLS tick over while standing around the driveway. When the car first pulled up in mine, warm from some 40 miles of highway, it still sounded an awful lot like a 2.0T on a mid-March morning. Not to belabor the Brigitte metaphor, but I found as much Neilsenian dichotomy in the ride and handling as I did the exterior styling. Especially with Mercedes' 4Matic system spreading out the grip, I found the CLS to be sharp when pushed, and rather excellent in terms of making quick corrections while under a cornering load. And yet, you've got to push through an initially soft suspension response to reach that hard edge. The CLS will initially resist being tossed around a winding backroad, but press on and she'll do as you ask.

US buyers show little interest in big hybrids

The idea of producing large, luxury-vehicle hybrids is turning into a "what were they thinking?" exercise in futility, USA Today reports. General Motors is discontinuing hybrid versions of the Cadillac Escalade, Chevrolet Tahoe and GMC Yukon SUVs, while Mercedes-Benz and Toyota's Lexus division are doing the same with their S-Class hybrid and LS hybrid sedans, respectively. The culprit? Big price increases for fuel economy improvements that border on the unimpressive. Granted, the Escalade hybrid gets 31 percent better fuel economy than the standard version, but that still maps out to a combined fuel-efficiency rating of just 21 miles per gallon. That can be seen as a worthwhile increase, if it didn't cost over $8,000 extra. The 2014 Escalade Hybrid, for example, starts at $74,425 while the non-hybrid can be had for $66,295. Meanwhile, the Lexus full-size hybrid costs $6,000 more than the regular version but only gets 1-2 mpg better combined fuel economy. The result of all these high costs? Low sales. Through April, GM sold 82 of its hybrid SUVs and pickups, down from 541 a year earlier. And the LS hybrid sales were in single-digit territory for April. That isn't stopping Lexus from promoting its hybrids as the right solution (with the wrong facts), though. There are still automakers giving big hybrid vehicles a shot, though. Nissan's Infiniti division is selling a hybrid version of its QX60 and says an impressive 10 percent of QX60 buyers choose the hybrid, which costs just $3,000 more. Looks like money talks.
