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.

New Mercedes-Maybach concept set to debut at 2018 Beijing Motor Show

Mercedes-Maybach builds some of the most kitted out and opulent production cars in the world. Think of the Maybach S 560 and S 650 as a Mercedes S-Class taken to the next level of luxury. Today, Mercedes-Maybach revealed a new teaser for what looks like a concept for a new EV. The car is set to debut in just a few weeks at the 2018 Beijing Motor Show. This might be the Maybach SUV we reported on a few weeks back. It's difficult to make out too many details, but it definitely looks different than the Vision Mercedes-Maybach 6 that we've seen floating around for the past couple of years. A close-up shot of the steering wheel shows the soft blue glow that Mercedes has put on the EQ-branded concept cars. Other images show clean white leather, rose gold trim and a pair of seats flanking a flower-encrusted panel. All the shots appear to be of the concept's interior, so we can't say for sure that this is the rumored Maybach SUV. Either way, it's sure to be just as luxurious and formidable as anything the automaker currently has on the road. We're hoping they come up with another G-Class Landaulet.

Mercedes out to defend its F1 crown with new W06 Hybrid Silver Arrow

They say there's only one way to go when you're on top, and that's down. That's the direction in which every other team on the Formula One grid will be trying to push Mercedes this season, but the defending champions will be doing their best to stay on top. What you see here is the embodiment of that effort. After taking pole position at all but one race last season, the checkered flag at all but three and an impressive dozen one-two finishes, the new Mercedes AMG F1 W06 Hybrid will have one heck of an act to follow. In accordance with the only major change to the sporting regulations for 2015, the most obvious difference over last year's W05 is the revised front end, but the team insists it worked hard over the winter to optimize everything underneath that silver and teal bodywork, from the suspension to the turbocharged hybrid power unit and everything in between. One of only two teams (alongside Ferrari) on the grid this season to develop its own engine in-house, the Mercedes PU106A proved practically unbeatable last season. And with engine development all but completely frozen in the off-season, its innovations are likely to prove just as insurmountable this year. But as team principal Toto Wolff puts it, in quoting Babe Ruth, "Yesterday's home runs don't win today's games." While nothing's for certain in one of the world's the most competitive arenas, chances are still high that Mercedes will continue to dominate this season just as it did the last. The most gripping battle, then, may very well be waged once again between Lewis Hamilton and Nico Rosberg, whose rivalry started long before either got their start in F1, from karting and up through the ranks of the lower formulae. Though Lewis was just crowned world champion for the second time, Nico has been with the Mercedes team for longer, has been in F1 for longer and didn't give up on chasing Lewis all of last season – so don't expect him to this year, either.
