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 Beetle special edition concepts hit NY [w/poll]

Buying a retro hatchback or convertible like a VW Beetle is nothing if not a fashion statement, and nobody knows that better than Volkswagen itself. Which is likely why the German automaker is bringing four concept versions of the Bug to the New York Auto Show this year. Most intriguing of the quartet – to our eyes at least – is the Beetle R-Line concept, which takes a more performance-oriented approach. It's got 20-inch alloys riding on a wider track, an aero pack including a rear diffuser and spoiler, and black trim that looks great in contrast to the white pearl finish. The interior has been upgraded, as well, with sport buckets, carbon trim and yellow details, and the concept is powered by the 2.0-liter TSI engine with 217 horsepower. The R-Line concept won't be taking the stage alone, however, joined as it will be by the magenta-sprayed Pink Color Edition hatch, the beach-themed Wave and jeans-wearing Denim edition convertibles. Though all are billed strictly as showcars for the time being, VW admits it will be gauging public reaction to all four to determine potentially putting them into production for public consumption. So, that in mind, have a look at all the concepts in the gallery above, and tell us which one you like best in the poll below. VOLKSWAGEN AT THE 2015 NEW YORK INTERNATIONAL AUTO SHOW - Four Beetle Special Edition concepts introduced: Beetle Convertible Denim, Beetle R-Line, Beetle Convertible Surfer, and Beetle Pink Color Edition - All-wheel-drive Golf SportWagen Alltrack announced for production in 2016 - Volkswagen celebrates 60 years of Beetle heritage New York, New York - Volkswagen of America, Inc., today announced that it will produce the all-wheel-drive Golf SportWagen Alltrack for the U.S. market beginning in 2016, and showed four unique Beetle and Beetle Convertible models that help to commemorate Volkswagen of America's 60th anniversary. Golf SportWagen Alltrack Coinciding with the arrival of the all-new Golf SportWagen, currently available in dealer showrooms, Volkswagen is pleased to announce that the all-wheel-drive Alltrack model will go on sale in 2016 as a 2017 model. "We have heard from dealers and customers that they want to see a Golf SportWagen with the all-terrain capability that comes from all-wheel drive," said Michael Horn, President and CEO of Volkswagen Group of America, Inc.

VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.
