2015 Austrian F1 Grand Prix switches to alternating current

It's called the Red Bull Ring, guests are welcomed by a statue of a leaping bull, and dominating its layout demands powerful cars that can run it hard. Perhaps all that aggression is what led both Mercedes-AMG Petronas cars to run off the track in the final qualifying session on their final hot laps, a little too aggressive on the charge. Lewis Hamilton was first into the gravel at Turn 1 when he lost his car under braking, but he was still fast enough to get pole ahead of teammate Nico Rosberg, who spun at Turn 8. Rosberg started second. Or perhaps it wasn't the red bull but the scarlet horse that caused The Silver Arrows to muck it up: Ferrari driver Sebastian Vettel had Mercedes' attention all weekend, and he'd line up in third just 0.355 off Hamilton's time. Williams truly rediscovered its power, Felipe Massa going fourth fastest, teammate Valtteri Bottas in sixth. Between them was newly-minted Le Mans winner Nico Hulkenberg, yet again – can we say that enough? – pulling the still-not-updated Force India to fifth place on the grid. Max Verstappen led the Renault-powered top-ten duo in his Toro Rosso in seventh, Infiniti Red Bull Racing driver Daniil Kvyat behind him in eighth. Kvyat, however, would start down the order because of a ten-place grid penalty for needing a fifth Renault engine. After that it's back to Mercedes Ferrari power, Felipe Nasr in the Sauber in ninth, Romain Grosjean in with Mercedes power in the Lotus in tenth – but fellow Lotus driver Pastor Maldonado actually started in tenth because of Kvyat's demotion. Before we get to the race, can we take a moment to talk about the shenanigans and gaudy penalties? Kimi Raikkonen waved the Ferrari flag in Canada after a season that's been full of "We didn't get it right this time," and we thought he was back. But no. In Austria the refrain returned, the Finn kicked out of Q1 after another miscommunication with the team – he qualified 18th. If the scenario plays to form, we'll now wait for team boss Mauricio Arrivabene to issue a clarification that suggests Raikkonen missed a step. Daniel Ricciardo parachutes ten spots back for the same reason as his teammate Kvyat, needing a fifth Renault power unit, dropping him to 18th on the grid and forcing him into a five-second time penalty when he comes in to pit.

Mercedes testing C-Class plug-in hybrid modes in Germany

Testing appears to be underway for what would be the first Mercedes-Benz C-Class with a hybrid powertrain. We can see a pair of the prototypes undergoing testing in Germany, with one, a C-Class Wagon, still heavily clad in camouflage and featuring a more noticeable outlet on the passenger side of its rear bumper.
There's also a more production-looking sedan, which features a not-so-discreet flap over its rear-bumper outlet. It's difficult to speculate on power outputs for this fuel-sipping C-Class, although our spies seem to think that this car will feature some combination of a four-cylinder gas engine with an electric motor, although just which four is unclear (note, we wouldn't mind if MB fit its 2.0-liter turbo with some batteries and motors). Regardless, the four-pot/electric motor seems like a pretty reasonable combo, although it probably means that Mercedes won't be challenging the six-cylinder-powered system of the BMW ActiveHybrid3 any time soon.
When the plug-in C-Class arrives later this year as a 2015 model, it will likely offer a full range of driving modes, including both gas or electric, only, as well as a more traditional hybrid mode.

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.
