Why all of this year's F1 noses are so ugly [w/video]

If you're a serious fan of Formula One, you already know all about The Great Nosecone Conundrum of 2014. Those given to parsing each year's F1 regulations predicted the strong possibility of the so-called "anteater" noses as far back as early December 2013. Highly suggestive visual evidence first came after Caterham's crash test in early January, with further proof coming as soon as Williams showed a rendering of the FW36 challenger for this year's championship. That car earned a name that wasn't nearly so kind as "anteater."
Casual followers of the sport - or anyone who gets the feed from this site - probably don't know what's happening, except to wonder why the current year's F1 cars are led by appendages that would make Cyrano de Bergerac feel a whole lot better about himself.
The short answer to the question of ugsome F1 noses is "FIA regulations and safety." The reason there are various kinds of ugsome noses is simpler: engineers. The same boffins who have given us advances including carbon fiber monocoques, six-wheeled cars, double diffusers and Drag Reduction Systems are bred to do everything in their power to exploit every possible freedom in the regulations to make the cars they're building go faster - the caveat being that those advances have to work within the overall philosophy of the whole car.

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 to roll out S65 AMG Coupe in July

We're still a couple of weeks away from the public debut of the new Mercedes S63 AMG Coupe at the fast-approaching New York Auto Show, but already we're receiving word of an even more powerful version in the works. That, of course, would be the S65 AMG Coupe - the twelve-cylinder version of the latest S-Class Coupe, two-door counterpart to the S65 AMG sedan and replacement for the outgoing CL65 AMG.
Like the four-door version rolled out back in November, the S65 AMG Coupe would be distinguished from less powerful vehicles (which, lets face it, is just about everything) principally by its engine: a massive, 6.0-liter twin-turbo V12 that produces 621 horsepower, 738 pound-feet of torque and cares as much about global warming as an oil-shipping mega-tanker.
Because Merc's 4Matic all-wheel drive system can't handle that much torque, the ne plus ultra coupe would (like the S65 sedan but unlike the S63 coupe) be offered only in rear-drive form. That means it will have that much more trouble getting the power down to the road, but since the Magic Body Control suspension is similarly incompatible with 4Matic, the flagship coupe will get that trick suspension.
