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.

VW going turbo-only in 3 to 4 years

This really was a matter of when, rather than if. Volkswagen will apparently be the first manufacturer to phase out naturally aspirated engines in favor of turbocharging its full slate. VW is kind of responsible for ushering in this push towards small-displacement, turbocharged engines that's taken the industry by storm. When it dropped its direct-injection, 2.0-liter turbo in the 2005 GTI it demonstrated that strapping an iron long to an engine can enhance the powertrain as a whole. VW made fuel economy gains, while also giving a linear, non-laggy turbo experience that it has replicated, model-after-model, to this day.
Speaking with The Detroit News, Volkswagen's executive Vice President of Group Quality, Marc Trahan, told the paper that, "We only have one normally aspirated gas engine, and when we go to the next generation vehicle that it's in, it will be replaced. So three, four years maximum."
Really, it's hard to get teary-eyed about either of these engines going away. VW has access to smaller powerplants that could easily match the performance of the 2.5 five-cylinder and the 3.6 V6, while gobbling up less fuel and providing a better driving experience. What we are sad about is that a similar statement about the extinction of NA engines came from the Vice President of Powertrain Engineering at Ford, Joe Bakaj. We'd certainly get teary-eyed over a world without Ford's excellent 5.0-liter V8.

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.
