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 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.

Daimler employees can set email to auto-delete during vacation

The Internet has shrunk the world in terms of the way people communicate by making it possible to send an email from Oslo and have it show up in Cleveland almost immediately. But that instant contact has wrecked the work/life balance for many. They get home from a long day at the office, yet they can never fully put their feet up and relax because another hour or more of checking and replying to emails awaits. However, German automotive giant Daimler is putting an end to that churn, at least while its employees are on vacation.
About 100,000 Daimler employees in Germany are eligible to opt-in to a new program called Mail on Holiday, according to The Atlantic. When the workers go on vacation, they can switch it on, and the service auto-deletes all of their incoming email. "Our employees should relax on holiday and not read work-related emails," said Wilfried Porth, board member for human resources, to The Financial Times as cited by The Atlantic.
Mail on Holiday puts a thumb on the scale of work/life balance in favor of a little more free time. The system means that Daimler employees shouldn't even be tempted to check their email on vacation because there's nothing there - and it also avoids them coming back from a relaxing holiday only to find a mailbox packed full of hundreds of unread messages. These days, people are absolutely obsessed with their work, often to the detriment of their health, not to mention spending time with their families and friends. On one hand, Mail on Holiday sounds like the sort of vacation breakthrough we'd need to truly unplug and unwind, but on the other hand, it makes our skin crawl just thinking about the lack of communication.
