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.

Sunday Drive: A new Rambo Lambo takes center stage

Surprise! Autoblog readers love fast cars. Doesn't matter what shape; doesn't matter what size. As long as it's got big power, wicked acceleration, and ludicrous speed, you're interested. Take, for instance, the brand-new Lamborghini Urus. It's got a 4.0-liter twin-turbocharged V8 sending 641 horsepower and 627 pound-feet of torque through an 8-speed automatic transmission to all four wheels. It hits 62 miles per hour in 3.6 seconds, and has a top speed of 189.5 mph. Ludicrous speed? Check. And although you'd be hard pressed to draw a line straight back from the upcoming Urus to the old, off-road-ready LM002, at least you can say that Lamborghini does have a history of producing overpowered SUVs. A 5.2-liter V12 engine producing 444 horsepower and borrowed from the Countach certainly qualifies as big power, especially considering this was in the 1980s and '90s. A prime example just sold for nearly half a million bucks. Moving along to more traditional sportscars, we got a sneak peek at the next Porsche 911's interior, thanks to some intrepid spy photographers. And we spy with our little eyes some major changes to the quintessential German sportscar. Finally, we round out this Sunday Drive with two First Drive reports. Both are German, but past that, they couldn't be more different. Either way, ludicrous speed is all but guaranteed by either one.

Recharge Wrap-up: KillaJoule hits 270 mph; Mercedes B-Class ED gets PlugShare

The Mercedes-Benz B-Class Electric Drive will get its own version of the PlugShare charging-station locator app. Developed by Recargo with the help of Daimler, the vehicle-specific app will be integrated into the car's navigation system. The system maps the location of nearby charging stations from various networks. So far, Mercedes-Benz doesn't offer a universal pay service for the various charging networks, like those offered by BMW and Nissan. Read more at Green Car Reports. HyperSolar uses solar energy to make hydrogen from water. Without using electrolyzers, HyperSolar uses a photochemical process to separate and capture the hydrogen in the water, which can then be used for clean energy, such as automotive fuel cells. The solar devices are submerged in water inside a container, and sunlight powers the device to free the hydrogen. HyperSolar claims that its process is more efficient and cost effective than other methods used to produce hydrogen from water. See some demonstrations in the videos below and learn more at HyperSolar's website. Eva Hakansson drove the KillaJoule electric motorcycle to a top speed of 270.224 miles per hour. After a computer model showed a possibility of about 270 mph, the team took the motorcycle with sidecar out to the salt flats for Mike Cook's Shootout. Everything went smoothly, and Hakansson easily surpassed speeds of the 249.1-mph world record she set a few weeks ago. The team is calling it quits for the season, but will make some tweaks to the KillaJoule in hopes of getting 300 mph out of the red bullet next year.
