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 releases 6x6 G63 AMG specs and pics [w/video]

Mercedes-Benz has finally dropped full details on its insane G63 AMG 6x6. The machine puts 544 horsepower to all six wheels thanks to a twin-turbocharged 5.5-liter V8. A seven-speed gearbox shuttles power to the ground via three sets of portal axles, which helps give this machine a full 15.75 inches of ground clearance. By comparison, the standard G63 AMG sits with just 8.27 inches of ground clearance. The extra lift allows this 6x6 to ford nearly 40 inches of water and run massive 37-inch tires. All told, there are five differential locks on this thing, all controlled by a special "locking logic" that provides the best traction possible for any given situation.
The controls offer up three stages of locking, which we can only assume range from JKLOL to OMGWTF. Right now, AMG says this monstrosity is only a show vehicle, but we imagine it wouldn't take much to convince the team to whip up one of your very own. Check out our full gallery and the press release below for all the nitty gritty. While you're down there, you can also check out the video on the machine one more time.

Weekly Recap: An '80s encore in the auto world

The '80s returned in a big way this week, as National Lampoon's, Ghostbusters, Miami Vice, and even Tetris were back in the news. While there were far more serious topics (see below), nostalgia mingled with modern marketing to put these Reagan-era favorites back in the spotlight. The '80s were alternately cold and corny at times, but their cultural touchstones can still generate big money. That's why Infiniti recreated an iconic scene from National Lampoon's Vacation (1983) for an advertisement that hawks the QX60 crossover. Actor Ethan Embry, who played Rusty Griswold in a later Lampoon's movie, pilots the Infiniti – which is serving as a modern Family Truckster – for a trip to Walley World. A blonde pulls alongside in a red Lamborghini. They flirt, and she drives on. Christie Brinkley, who played the original girl in the red sports car (she drove a Ferrari in the '83 flick), is riding shotgun and chides Embry with: "A blonde. In a convertible. Seriously?" Okay, it's hardly on the level of "here's looking at you," or even "you can't handle the truth," but it should resonate with '80s babies, many of whom are now having children of their own and moving into three-row SUVs like the QX60. Naturally, Hollywood is going back to the well, too, with a Vacation remake that premiers July 29. Meanwhile, Ghostbusters is returning next year, and director Paul Feig offered a peak at the new Eco-1 in this tweet. In the 1984 classic, the team drove a modified 1959 Cadillac. Now, it will drive a late '80s Cadillac. As expected, the announcement generated support and controversy from movie and car enthusiasts. His tweet had generated several thousand retweets and favorites in the days following the news. Though the '80s Caddy looks, uh, less elegant in comparison to the now-iconic fins and curves of the original Ecto-1, it's about the same time lapse into the past as the '59 Caddy was to viewers in 1984. Speaking of 1984, Miami Vice, which debuted that year on NBC, is seeing one of its hero cars hit the auction block, Mecum Auctions announced this week. The 1986 Ferrari used on the show will be offered for sale Aug. 15 during Monterey classic car week. The white supercar runs a 390-hp flat 12-cylinder engine paired with a five-speed manual transmission and was in storage after the show ended in 1989 until earlier this year. It has 16,124 miles on the odometer and is authenticated by Ferrari North America and Classiche.
