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.

2015 Bahrain F1 Grand Prix puts a dark horse in the desert [spoilers]

Ferrari's Kimi Raikkonen had said after Malaysia that Ferrari can challenge Mercedes-AMG Petronas purely on pace, beyond the scope of tire wear, in the dry. We didn't see that in China, where Lewis Hamilton easily kept everyone behind and Ferrari's Sebastian Vettel only got close to Mercedes' Nico Rosberg when Rosberg slowed down to conserve his tires. But the Iceman's words seemed prescient during qualifying for the Bahrain Formula One Grand Prix. At the front, nothing has changed so far this year: four races, four pole positions for Lewis Hamilton. Instead of teammate Rosberg next to him, though, he'll look over to see the scarlet Ferrari of Vettel, who took advantage of Rosberg's cautiousness to snatch second place on the grid. In Q2, Rosberg tried to conserve the tires he'd start the race on and said he couldn't get into a groove in Q3, putting in a time 0.147 seconds slower than Vettel. The second Silver Arrows will share his row with the second Ferrari, Raikkonen – yet again – saying he might have left some time on the table during his hot lap but getting around just one tenth off Rosberg's time. Williams is established as the best of the rest behind two teams this year instead of just one last year, Valtteri Bottas claiming fifth ahead of Felipe Massa. Daniel Ricciardo of Infiniti Red Bull Racing said he wants to fight with the Williams', he'll be helped with a good start off the line for the first time this year. Nico Hulkenberg got Force India into Q3 for the first time since the Italian Grand Prix last year and into eighth on the grid, ahead of Carlos Sainz in the Toro Rosso and Romain Grosjean putting in another excellent day's work for Lotus. Come race time, it turned into Mercedes power against Ferrari strategy. When Sky F1 commentator Martin Brundle talks about the Mercedes-AMG Petronas team he often mentions how their engine advantage leads to other advantages throughout the car. Not having to use aerodynamic changes to make up for power unit deficiencies, for instance, means they can run the aero setup they want, which optimizes speed and tire wear throughout a lap. It equates to advantage on top of advantage on top of advantage. That's where Lewis Hamilton is right now, so fundamentally dialed in to his car and his racing that he run the races he wants to run. From the front spot, the Brit ripped off another perfect start and led the field into Turn 1, relinquishing the lead only during pit stops.

Recharge Wrap-up: liquid-cooled Tesla Supercharger, Acenta+ Leaf

A new video offers a close look at Tesla's updated Supercharger. Recently, Elon Musk spoke about the new charging station with a thinner, suppler liquid-cooled cable that is not only easier to manage, but has the potential to handle larger loads and offer quicker recharging. The first examples have been installed in Mountain View, CA, which we can see in this video. Besides the new cable, the new Supercharger also features a solid "button" on the charging handle as well as vents around the bottom of the unit. The video even shows thermal imaging of the new Supercharger, which shows the cable to be cooler than the cameraman usually records. See for yourself in the video above, and read more at Treehugger. Nissan has added a new trim level to the Leaf in the UK. The Acenta+ slots above the Acenta and just below the range-topping Tekna. It comes standard with the 6.6-kW onboard charger and Mode-3 32-amp (EVSE) cable. Using a fast charger, the Acenta+ Leaf can charge to 100 percent in just four hours. "We're delighted to add a new member to the Leaf family in the UK," says Nissan Motor GB Managing Director James Wright. "More than 9,500 Leafs have already been sold here and Nissan is the undisputed leader in the EV market. This new model delivers exceptional value and showcases the Leaf's incredible technology and engineering." Read more at Next Green Car. Mercedes-Benz Malaysia says its vehicles are compatible with B10 biodiesel blend. Malaysia recently announced a mandate for diesel to be sold blended with 10 percent palm-oil based biodiesel, after which, carmakers like BMW and Mercedes-Benz came forward with concerns over compatibility with their vehicles. "We have evaluated carefully the influence of B10 Biodiesel blends on our current diesel vehicles for the Malaysian market and we are now able to confirm its compatibility," says Mercedes-Benz Malaysia President and CEO Roland Folger. "We have service intervals of 12,000 km to ensure that our customers are not affected by the diesel quality. Our diesel-powered vehicles currently sold in Malaysia were seen to have run both smoothly and safely with the use of the B10 biodiesel blend." Read more from Paul Tan's Automotive News.
