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.

Weekly Recap: Takeaways from the Frankfurt Motor Show

We obsessively covered the 2015 Frankfurt Motor Show, and naturally, we selected our favorites from this fall's biggest automotive event. Now that the dust has settled, we're looking ahead to what it all means. Here are three takeaways from the floor in Frankfurt. The Germans are serious about electric vehicles: It's a bit cliche to say BMW, Mercedes, and Audi have downplayed electrics in favor of other technologies, like diesels. For a time that may have been true, but those three companies, along with Porsche and Volkswagen, are emerging as leaders in EV development. That was on display in Frankfurt, when all of them revealed either all-electric or plug-in hybrid models. Gas prices are relatively low in the United States, but clearly the Germans are thinking long-term and globally. Everyone is serious about SUVs: You gotta have one, even if you're Bentley or Jaguar. It's 2015 and it's what consumers want. As Jaguar design director Ian Callum put it, "Not to be in the sector would be a little naive for the sake of purity." It's not just the flashy exotic luxury makers. Nissan showed the Gripz concept, which is rakish, radical, and meant to blend traits of SUVs and sports cars into a vehicle that really crosses over. Look for more, especially in the luxury sector, as Rolls-Royce, Lamborghini, and Aston Martin ramp up their own SUV efforts. There's no ceiling to the luxury market: Speaking of high-end cars, companies are continuing to invest in extravagant wares beyond just SUVs. Even during the recession, ultra-luxury makers remained relevant, and now they're back at full stride. In Frankfurt, that was illustrated by yet another S-Class model, the cabriolet, which will come in S550 and S63 AMG variants in the United States. Ferrari also showed off the 488 Spider, and Lamborghini opened up the Huracan LP 610-4 Spyder. Meanwhile, Bugatti's Vision Grand Turismo concept reminded enthusiasts that it's plotting life after the Veyron. European auto shows always draw the glitziest reveals from luxury makers, and this year didn't disappoint. OTHER NEWS & NOTES 2016 Honda Civic redesigned with snazzier style, turbo power The 10th-generation of the Honda Civic debuted this week at events in Los Angeles and Detroit ahead of its launch in the United States this fall as a 2016 model.

Mercedes raises the roof on new CLA Shooting Brake [UPDATE]

UPDATE: As we feared, the CLA Shooting Brake is not currently slated for US availability. The text below has been adjusted accordingly. Of all the variants in Mercedes' smallest line, only one doesn't have a liftgate, and that's the CLA-Class. But don't worry, the German automaker is out to fix that too with the reveal of the new CLA Shooting Brake you see here. Based on the same platform that underpins the CLA four-door coupe, the A-Class hatchback, B-Class minivan and GLA crossover, the new Shooting Brake applies a similar formula we've already seen on the bigger CLS Shooting Brake but in a much smaller form – which is to say, it's a wagon, but a shapely one. The revised roofline means more headroom in the back seat and significantly more cargo capacity than the four-door's trunk. Mercedes will offer the CLA with a variety of engine choices, including a 2.1-liter turbodiesel with either 136 or 177 horsepower, a 1.6-liter four with 122, 156 or 211 horsepower. That last model will even be available with 4Matic all-wheel drive for those not enamored by the idea of a front-drive Benz, but the top of the range, of course, is the CLA45 AMG Shooting Brake that carries the same 2.0-liter turbo four – all 360 horsepower of it – as the four-door CLA45 as well as the A45 and GLA45. Driving once again to all four wheels, Daimler says it'll reach 62 in 4.7 seconds (even quicker than the crossover) and top out at the usual 155 miles per hour. Of course those options only apply to markets where the new Shooting Brake will be offered. And unfortunately, Mercedes-Benz USA confirmed to Autoblog that (like the CLS wagon) the CLA Shooting Brake won't be making the transatlantic voyage to US showrooms (where the E-Class is the only low-slung Benz wagon on offer). That leaves the four-door CLA and the GLA crossover still holding down the pint-sized fort for Mercedes. THE NEW MERCEDES-BENZ CLA SHOOTING BRAKE: SPACE FOR SOMETHING NEW Stuttgart. Breathtakingly sporty proportions and a powerfully dynamic design idiom with sensuously shaped surfaces already made the CLA unmistakable in its four-door Coupe guise. It is now followed by a further design icon, the CLA Shooting Brake, with a unique look all of its own. The lower overall height and the elongated coupe-style roof contour line, the low greenhouse and the sweep of the high beltline are the key design features of its distinctive profile.
