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-Benz GLE Coupe is ready to tackle BMW's X6

Under the chiseled hood of the GLE 450 AMG sits a 3.0L, twin-turbo V6 with 362 hp and 384 lb-ft. Years after the polarizing BMW X6 originally hit the market, Mercedes-Benz has finally unveiled its slope-roofed challenger, and much like Munich's Sport Activity Vehicle, we think the new GLE Coupe will split opinions rather dramatically. While it clearly shares its form factor with BMW's X4 and X6, the GLE Coupe's styling is all Mercedes, borrowing the more organic shapes used on the company's most recent new model, the AMG GT. Strips of chrome and the iconic silver arrow logo bisect a large, rectangular grille, while the fascia on the GLE 450 shown above features three rather dramatic lower air intakes. The headlights, meanwhile, fit in with MB's latest styling language. In back, slim, wraparound taillights share some resemblance with the new S-Class Coupe. The cabin is recognizable and looks to be of extremely high quality, with the featured vehicle showing off quite a lot of carbon-fiber trim. A thick-rimmed, flat-bottomed steering wheel dominates the driver's area, while a large, tablet-like display crowns the center stack. The same sort of touch-controlled interface and input dial found on the new C-Class controls the information on that screen. Under the chiseled hood of the GLE 450 AMG, the first of Mercedes' AMG Sport models, sits a 3.0-liter, twin-turbocharged V6. Unlike the 329-horsepower unit in the C400 and E400, the force-induced V6 generates 362 hp and an equally robust 384 pound-feet of torque. It's mated up to a new nine-speed automatic transmission and Mercedes' 4Matic all-wheel-drive system. A new version of the popular Airmatic suspension is being offered with the ADS Plus continuously variable dampers while Mercedes is also fitting its Active Curve System, complete with active roll stabilization. Mercedes doesn't provide many additional details on the GLE Coupe range, as it were. We know about the 450 AMG, but it's not clear whether there will be a GLE 400 or non-AMG 450, or if Mercedes will move it down market and offer a GLE 350 to compete with the X6's xDrive35i. There's also no mention of when or where the new model will debut, although previous reports point to the 2015 Detroit Auto Show. Prices and an on-sale date, meanwhile, have not been revealed.
