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.

Mercedes FWD platform to last until 2018, convertible and two-seater future uncertain

Mercedes-Benz seems to be expecting a lot of success from its front-wheel-drive CLA-Class. Automotive News is reporting that the sub-C-Class sedan could grow when its second generation arrives in 2018.
The current FWD platform for MB underpins the CLA, the B-Class, the GLA-Class, and the A-Class. The B-Class will arrive in North America as an EV for spring of 2014, while the production GLA crossover will arrive three to four months after that. The five-door A-Class won't be crossing The Pond. Sad faces all around.
According to AN, another model will be based on the front-drive architecture, but it won't be coming to the US market. Set to arrive next year, rumors are that it'll be a wagon version of the CLA, sort of like the ill-named five-door CLS Shooting Brake that is also a Europe-only item.

The 10 car brands most expensive to maintain over 10 years

Car maintenance has got to be one of the least fun things you can do with your free time, right behind going to the dentist and filing your taxes. However, depending on the brand you buy, your time spent at the shop could be much more than you bargained for. Consumer Reports’ new study on the most- and least-expensive-to-maintain car brands found that European car companies are most likely to break your wallet with costs nearly five times that of the automakers at the other end of the spectrum. Land Rover had the highest ten-year maintenance costs, at an average of $19,250. Porsche was second worst with $14,090 in costs. 10 car brands most expensive to maintain over 10 years: Land Rover: $19,250 Porsche: $14,090 Mercedes-Benz: $10,525 Audi: $9,890 BMW: $9,500 Volvo: $9,285 Infiniti: $8,500 Acura: $7,800 Mini: $7,625 Subaru: $7,200 The Euro brands at the “top” of this list arenÂ’t all that surprising. Land Rover has consistently landed as one of the most expensive vehicle brands to maintain for years now, though Porsche is generally viewed as being one of the more solid performance brands. That could suggest that some models donÂ’t always require more repairs, but the fixes they do need are significantly more expensive. Tesla, Buick, and Toyota were the three cheapest to maintain car brands, with 10-year maintenance costs of $4,035, $4,900, and $4,900, respectively. Consumer Reports noted that these numbers could be slightly skewed due to the fact that some automakers offer free maintenance for the first few years of ownership, and all companies cover their new vehicles for at least a few years after the purchase. Routine maintenance is a great way to avoid costly repairs over time, as itÂ’s much cheaper to catch a problem before it starts causing other issues. Check your oil, rotate your tires, and avoid driving like a wild person, and youÂ’ll likely fare much better than others, even if you own one of the scarier-to-maintain brands.
