2014 Mercedes-Benz SLS AMG Black Series [w/video]

Now Even Sharper Than The Razor's Edge
There have been five Black Series models since the Mercedes-Benz SLK55 AMG Black Series introduced itself to European audiences in 2006. Following that, the Black Series club has hosted appearances by the 2008 CLK63 AMG Black Series, the 2009 SL65 AMG Black Series and last year's 2013 C63 AMG Black Series. The sixth member of the group is one we would have thought already was a Black Series car in its standard guise. Right out of the box, the SLS AMG is loud, frenetic, cozy, boisterous and frightfully easy to oversteer. How much more Black did it need to get?
Quite a bit so, apparently. The SLS AMG Black Series has lost weight, gained power and been refitted with upgrades and aero bits from front to rear. If you liked the way it looked before, you'll probably be an even bigger fan of this one. If you thought it looked ungainly, well, this one should stay even further away from pageants. Regardless of where you come down this is the best SLS AMG variant we've driven.

YouTube's Super Bowl commercial buzz list dominated by automakers [w/videos]

After Sunday's big game, YouTube will be the place to watch every commercial that you missed when you left your seat for an emergency guac refill or, as we say in Cleveland, took the Browns to the Super Bowl. That makes YouTube the nation's water cooler on Monday, and it's got some preliminary stats to share in the lead up to kickoff.
As you know, Super Bowl advertisers, particularly automakers, like to endlessly tease their big budget commercials in the weeks before the game, many times revealing them outright days in advance. Because of this, YouTube can tell us which commercials have been viewed the most so far, and their top five list is all automakers.
Kaley Cuoco appears to have been a good investment for Toyota, as her ad for the RAV4 has garnered the most YouTube views - six million and counting - among Super Bowl commercials so far. Second place goes to Mercedes-Benz, though not its actual Super Bowl commercial, but rather the teaser for it. You know, the one with Kate Upton and the car washing, which is up to 5.6 million views. Third place is Audi's Prom commercial (3.3M views), fourth goes to Volkswagen's slightly controversial Get In, Get Happy ad (3.3M views), and the fifth and final spot is bookended by the teaser video for Kaley Cuoco's commercial (3.2M views). You can watch all five in order below.

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.
