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 could build plug-in hybrids in China

When you're Europe's largest automaker and your largest global market happens to be the one most notorious for its pollution (China), some solutions just present themselves. Volkswagen may be heeding that call. During the upcoming Beijing Motor Show, the company is expected to announce plans to produce plug-in hybrid electric vehicles in China, Reuters says, citing sources within the company. Few details have emerged, though the plug-ins will likely be produced at VW's Foshan factory in South China, which currently makes the Golf and Audi A3 and has plans to eventually make 600,000 vehicles annually. News has been percolating for a while, as Oliver Schmidt, general manager engineering and environmental office for Volkswagen Group of America, said last March that the company was planning at least two plug-in hybrid lines under the VW badge (and another three with its Audi and Porsche affiliates), including possibly a Touareg and Jetta PHEV. VW said late last month that it was looking to speed up development of "particularly eco-friendly models" made by Shanghai Volkswagen as well as developing a "new, very eco-friendly vehicle" with First Automotive Works (FAW). Earlier this year, VW unveiled its Golf GTE plug-in hybrid at the Geneva Motor Show. That model has a 1.4-liter turbocharged four-cylinder engine and an electric motor to provide 201 horsepower and 258 pound-feet of torque. The car can travel as many as 81 miles on electric power alone.

Volkswagen planning Up! hybrid model using XL1 powertrain

Even though we've finally gotten a look at the production version of the 261-mile per gallon Volkswagen XL1, this aero-shaped two-seater was never intended for high-volume sales. Fortunately, it sounds like the same isn't true for the car's diesel plug-in hybrid powertrain, which, according to a report from AutoCar, could make its way under the hood of another Volkswagen model: the Up! minicar (shown above).
A potential Up! Hybrid would likely be able to return some of the same impressive fuel economy numbers as the XL1, but it would be a more realistic car with more passenger space and greater production capacity. The hand-built XL1 will use a 47-horsepower, two-cylinder TDI engine paired to a seven-speed dual-clutch transmission, and the 27-hp electric motor and lithium-ion battery helps deliver an all-electric driving range of 31 miles.
One of the core pillars of the XL1's design is its lightweight construction with a 1752-pound curb weight, which makes the Up! a perfect recipient for using this powertrain since it weighs just 300 pounds more. The report says that the Up! Hybrid is still in the developmental phase, so a production version isn't expected for at least another 18 months.
