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.

Volkswagen CrossBlue previews a three-row future, diesel-hybrid power [w/video]

Volkswagen looks to be getting ready to jump into the large three-row crossover game. The automaker has officially pulled back the curtain on the CrossBlue Concept at the 2013 Detroit Auto Show.
Designers and engineers penned the machine specifically for the Canadian and US markets, and with a plug-in diesel electric hybrid drivetrain, the hulking five-door, at least in concept form, should offer substantially better efficiency than anything else on the market. The drivetrain pairs a 2.0-liter turbo diesel four-cylinder engine with two electric motors for a combined output of 305 horsepower and a ludicrous 516 pound-feet of torque. A six-speed dual-clutch gearbox handles shifting detail, while one electric motor spins the front wheels. The second motor spins the back axle independently, make the CrossBlue a through-the-road hybrid.
As a result, the crossover can pop to 60 mph in 7.2 seconds. Perhaps more impressively, the CrossBlue can whir around on all-electric propulsion for up to 14 miles at up to 75 mph. Once the diesel four kicks in, the drivetrain can yield up to 39 mpg, though Volkswagen says the hardware can hit 89 MPGe on a full charge thanks to a 9.8 kWh lithium-ion battery pack.

Five reasons to love, or hate, the culture of German cars

A few months back, we took a 500-foot view of the culture of American cars, dissecting prides and prejudices on our way to the conclusion that automotive allegiances can be simultaneously embraced and derided. We had so much fun with the narrative that we decided to do it again, this time taking a look at Germany and its world-renowned lineup of automakers, including the likes of Audi, BMW, Mercedes-Benz, Porsche and Volkswagen, among others. Join us below as we discuss the points and counterpoints that make or have made the German auto industry what it is today. And remember, Germany did pretty much invent the automobile, after all... The V12 Engine If America is known for the proliferation of the V8 engine, an argument could be made that Germany owns the V12. Yes, of course, other companies have created V12 engines – Ferrari, Jaguar and Lamborghini immediately come to mind – but the big 12-cylinder powerplants from BMW and Mercedes-Benz, in particular, have proven to be some of the most effortless, luxurious and downright over-built engines the world has ever seen. These days, having 12 cylinders is more a case of wretched excess than ever before, and yet, you can still stroll into your local BMW or Mercedes dealership and get a brand-new 760i, S600 or even an over-the-top G65 AMG, efficiency be damned. Best of all, since the majority of these German powerhouses depreciate as fast as an anchor sinks, nearly any auto enthusiast who dreams of a dozen cylinders can satisfy their carnal desires. Current Star: 2016 Mercedes-Maybach S600 View 28 Photos Diesel Engines Remember how we talked about those glorious V12 engines? Well, you can even get one from Audi that runs on diesel. If your compression-ignition fantasies err more on the side of fuel savings, that's no problem, either. Audi, BMW, Mercedes and Volkswagen have got you covered, with engines starting as small as 800 cubic centimeters (Smart Fortwo). If you want something a little more practical, it's hard to argue with a VW Golf TDI, which will provide plenty of space for you and three of your best friends, plus a fair bit of luggage, all while returning 50-ish miles per gallon. For the purposes of this discussion, we'd rather focus on the asinine levels of torque provided by Germany's high-end diesel engines than the lower-end fuel sippers.
