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.

Chris Harris and David Coulthard wring out a Mercedes Fintail at the N"urburgring

If there's one thing we've learned from the latest video from Drive, it's that the combination of Chris Harris and David Coulthard will produce some very quotable moments. Take this exchange, for example.
DC: "We are by some way the slowest."
CH: "But we're in a class of three cars, apparently."

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.
