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.

Hyundai tops VW and Buick in China, survey says

You may be aware of the long-time competition in China between Volkswagen and Buick, but another brand apparently should be in that conversation too: Hyundai. In a recently published annual consumer survey, the Korean company actually took the top spot to beat out its German and American rivals in second and third, respectively. The results were part of the China Brand Power Index that interviewed 11,500 people around the nation and was paid for by the country's Ministry of Industry and Information Technology. While Hyundai proved popular with voters, its sales haven't necessarily shown that yet. According to Bloomberg, the brand had falling numbers in China for the first quarter of the year. Even Ford outsold the South Korean automaker in the same period, despite scoring lower on the survey. Meanwhile, Audi ranked as the populace's favorite luxury brand, which is hardly a surprise given the Four Rings' strong sales in China. In January alone the automaker saw a 15-percent boost in volume there. Parent company VW's strong performance was somewhat more surprising, though. State media severely criticized the German automaker in March, and customers protested last year for the allegedly poor handling of a recall.

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.
