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.

Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.

Mercedes gets handy with Apple Watch app

Whether you yourself have been caught up in Apple Watch fever or not, automakers have been embracing the new wearable device one after the other. The latest is Mercedes-Benz. The MB Companion App for the Apple Watch initially focuses on seamless navigation. Punch in your destination on your watch or iPhone and it'll port over to the onboard navigation system in your Merc. Park the car, get out and the directions will switch back over to the Apple Watch to guide you from your parking spot to your destination on foot. It's similar to the app Mercedes had designed for Google Glass, only in this application it actually stands a chance of catching on. Designed by Benz's Silicon Valley R&D center, the Apple Watch app is being rolled out this fall in the new C-Class and S-Class equipped with the COMAND Online navigation system. It's earmarked to to spread to other models as well, with further updates to the app planned to allow it to display the vehicle's fuel level, range, odometer and maintenance code. Of course, Mercedes isn't the first automaker to release an app for the Apple Watch. It's not even the first German automaker to do so: BMW previewed its app for the device back in September, and Volkswagen got on board earlier this month. Mercedes-Benz to introduce new App: Guided all the way: Mercedes-Benz is one of the first to introduce Door-to-Door Navigation with Apple Watch May 15, 2015 Stuttgart/Sunnyvale. Mercedes-Benz creates an intelligent integration between Apple Watch and Mercedes-Benz vehicles with its new MB Companion App. The MB Companion App allows Mercedes-Benz costumers to search for directions on the Apple Watch or on iPhone initiating a complete door-to-door experience. A seamless integration unfolds: giving walking directions to the car on the Apple Watch, driving directions on the vehicle navigation system and again walking directions on the Apple Watch from the car to the final destination. The destination that the driver selects on Apple Watch is passed to Mercedes-Benz COMAND Online once the driver starts the vehicle. He then receives safe and non-distracting driving directions to his selected destination from Mercedes-Benz navigation. When the driver parks and leaves his car, Apple Watch gives him walking directions to the final destination making it the perfect guide for "Last Mile Navigation".
