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 AMG and Cigarette Racing debut 2,220-HP electric motor boat

Take the Mercedes-Benz SLS AMG E-Cell, stretch it and take off the wheels then make it float and you've basically got the just-unveiled Cigarette AMG Electric Drive Concept. Powered by an all-electric powertrain that offers 2,200 horsepower and 2,213 pound-feet of torque (and uses "numerous components" taken from the not-quite-as-yellow SLS AMG Coupé Electric Drive), the sleek concept is being called the "world's most powerful electric drive powerboat." What that means is a top speed of over 100 miles per hour from four 60-kWh lithium-ion batteries and two banks of six liquid-cooled, permanent-magnet synchronous electric motors. And the 240 kWh of total energy should provide plenty of juice out on the water.
Launched (but not literally) at the Miami International Boat Show today, the Cigarette AMG Electric Drive Concept is the result of a partnership between Mercedes-AMG and Cigarette Racing. The boat is 38 feet long (much longer than the 15-foot SLS) and is plastered with AMG branding on the sides and top of the bow above the matte chrome yellow paint (officially called AMG Electricbeam mango). Two 220-kW chargers can refill the batteries, dockside, in about seven hours.
The idea of a powerful electric boat is nothing new (Henrik Fisker talked about a plug-in hybrid watercraft late last year), but this is the first time we've seen Mercedes put its EV technology on the water. Anyone who's afraid of driving an EV in the rain should take note. Check out the complete press release below.

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.
