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.

2017 Mercedes-AMG C63 S Coupe First Drive

Remember 2008? The government said companies could make food from cloned animals. Derrick Rose became a Bull, Michael Phelps killed it at the Beijing Olympics, the Giants killed gamblers everywhere by beating the Patriots in the Super Bowl. The money that banks had been dousing in lighter fluid for years finally caught fire courtesy of Lehman Brothers. General Motors admitted it got torched for a $38.7-billion loss in 2007. Oil hit $147 a barrel. Tata introduced the Nano. And Mercedes-Benz gave us the W204 C63 AMG, a sedan we didn't know we'd been waiting for until we drove it. It was hammer in front and hell in back, that naturally aspirated 6.2-liter V8 with 451 horsepower and 443 pound-feet of torque swearing in Beelzebub's childhood tongue through four oval pipes jutting from a heart of black diffuser darkness. It was everything AMG had always been, howling mad in a straight line. And everything AMG hadn't been, sharp and fast through a turn. AMG booked a lot of goodwill for that endeavor, a substantial success that bred huge expectations. Not only would we not be surprised by the 2017 AMG C63 S, we would expect it to be outstanding. And it is. But not in the way we expected. What we love about the W205 C-Class sedan is the same thing that gives us pause about the AMG C63 S: they both grew up. The coupe shares only the doors, roof, and decklid with the sedan. The C63 Coupe shares only the doors, roof, and decklid with the standard production car. The hood is 60 millimeters longer, and there's a front splitter ready to make nasty crunching noises around town. The trunk gets a trim blade of a spoiler, strengthening the design connection to the S-Class Coupe. Blistered wheels broaden the C63 S Coupe by 2.5 inches in front and 2.6 inches millimeters in back, putting needed muscle on that otherwise svelte rear end and visually bolting the car to the road. Track is wider, too, and standard 19-inchers fill the wheel wells. It's a beautiful machine, and when draped in one of the 80 bazillion shades of matte silver AMG is known for, it's devastating. Our subjective take is that it's swapped personas with the BMW M4. Now it's the C63 S that channels muscular grace, while the M4 takes Bluto as its spirit animal. What's left to be said about Mercedes interiors, other than to give way for the heckling about the COMAND touchscreen placement? This interior does it like all the rest, with the exception of a small steering wheel with an absurdly fat rim.

Formula One's Valtteri Bottas can turn it up to 11 in Spain

BARCELONA - Valtteri Bottas can add his name to one of Formula One's longest sequences by following up his breakthrough win in Russia with another triumph when the European season starts in Spain this weekend. The Finn, fresh from his first Grand Prix victory with champions Mercedes in Russia, is the man most likely to become the 11th different winner in a row at Barcelona's Circuit de Catalunya. No other track on the calendar has had such a variety of winners over the past decade, an ironic fact given that it is the most familiar to drivers from winter testing and was once famed for its predictability. Last year it was Dutch 18-year-old Max Verstappen who became the sport's youngest winner when he triumphed for Red Bull, on his team debut, after both Mercedes drivers collided at the start. In 2012, it was now-departed Venezuelan Pastor Maldonado -- a one-hit wonder -- who handed Williams a surprise victory that remains their most recent. Ferrari's championship leader Sebastian Vettel and Mercedes rival Lewis Hamilton, 13 points behind the German, will start as favorites and success for either could be an omen given that both went on to take the title last time they won in Spain. But Bottas, who joined Mercedes from Williams in January as replacement for retired 2016 world champion Nico Rosberg, is the best bet to continue the streak of different winners in Spain even if he has yet to finish higher than fourth there. "Getting that first win definitely gives me a lot of confidence that I can do it, even though I always knew I had the ability," he said after Sochi. "And now it's done, I just want to do it again and again." RICCIARDO REVIVAL The only other driver from the leading trio of teams yet to triumph in Barcelona is Verstappen's Australian team mate Daniel Ricciardo, but the Red Bull has lagged Mercedes and Ferrari on pace so far this year. That will surely change, with the flow of upgrades set to speed up now that teams are closer to their factories, and Red Bull have some big chassis modifications in the pipeline with engine improvements still to come. "I hope the upgrade will give us a chance to really fight with Mercedes and Ferrari or at least get us closer," said Ricciardo. The driver of car number 11, Force India's Mexican Sergio Perez, has racked up 14 successive points finishes and he too will have aerodynamic updates on his car.
