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.

Consumer Reports selling its road-tested roadsters [w/video]

Here's a chance to acquire a celebrity-owned vehicles, and this time at a discount instead of a premium. So the celebrity in this case is Consumer Reports, that magazine that could be equally adored and abhored by car enthusiasts. CR buys all of its test vehicles and usually finds willing second owners within its own ranks, but its opening its small used-car lot to the public. On the forecourt are four roadsters: an automatic 2012 Audi TT 2.0 TFSI Quattro S-Tronic with 6,600 miles for $36,500, a manual 2012 BMW Z4 sDrive28i with 8,400 miles for $45,000, a manual 2012 Mercedes-Benz SLK250 for $39,500 and a manual 2013 Porsche Boxster with 7,000 miles for $48,000.
Those numbers mean a savings of $9,000 to $10,000 before haggling - each car is listed with an "Asking price" so there could be some wiggle room if you show up with pockets full of dough and eyes full of serious intent. Since the money CR earns from the sales go back into the magazine's budget to buy more test cars, however, it probably won't take any oddball trades, so you can forget about getting any purchasing help from that track-day AMC Javelin project on blocks in the back yard.
The vehicles have been taken care of and spiffed up for sale; buyers will take delivery at the CR test track in East Haddam, Connecticut and get a tour of the facilities. While you're there they'll even take you on a lap around the track so you can feel how your car handles when driven by one of its testers. They will probably not help you with advice on which toaster and dehumidifier to buy - you'll still need to get a subscription for that. Have a look at the video below to see a day in the life of a CR test car.

Mercedes-Benz killing Maybach in 2013, replacing with S600 Pullman

According to an unnamed Mercedes-Benz source speaking with AutoWeek, the German automaker is killing off its Maybach line in 2013.
The unsurprising news comes after the brand was resurrected in 2002, but failed to meet sales expectations with its two core models, the Maybach 57 and 62. Further solidifying its fate, a deal with Aston Martin to aid in the development of future Maybachs fell through earlier this year.
According to the AutoWeek insider, the plan is to continue to sell both Maybach models through the end of 2013, after which the fifth-generation S-Class will go on sale. When that happens, three new variants of the S-Class will be available, including an all-new, range-topping S600 that brings back the Pullman moniker and may be better suited to competing with the likes of Bentley and Rolls-Royce.
