Mercedes-Benz Concept GLA gets official ahead of Shanghai

Mercedes-Benz has something special planned for the Shanghai Motor Show - a new CUV concept that we first saw when it leaked on the internet yesterday. The GLA Concept compact crossover will hit the show stand with a turbocharged 2.0-liter four-cylinder engine producing 208 horsepower and 258 pound-feet of torque mated to a seven-speed dual clutch transmission and 4Matic all-wheel drive, and likely previews a new production model that we've already spotted testing.
That's not news, but the laser-based headlamps with video-projecting capability certainly are. Mercedes-Benz says the array can project any image or video onto a screen, which is handy since there are a pair of HD cameras mounted to the roof rack. The cameras can be removed and taken with you on all sorts of adventures. The lamps also feature a visible cooling system comprised of a series of fans, and the system helps give the headlights their "sparkle" effect.
Step indoors and the GLA offers up the interior of a high-quality crossover, complete with contrasting leather and plenty of aluminum. The automaker says the cabin was inspired by saddle craftsmanship with "more than 65 feet of hand-stitched seams to hold the raw edges of the leather together."

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.

2014 Mercedes SL and SLK add small expansion to Takata airbag recall

Mercedes-Benz is the latest automaker to be affected by Takata's massive airbag recall. The company has announced a voluntary recall campaign on a small number of model-year 2014 SLK- and SL-Class roadsters.
In Mercedes' case, 300 vehicles are affected, 200 of which are in the hands of customers. According to spokesperson Donna Boland, the affected roadsters were built between March and April of this year.
The issue, which is apparently the fault of one of Takata's subcontractors, rests with some improperly installed fasteners, which could keep the airbag from performing the way it's supposed to. According to Boland, Mercedes isn't sure what, if any, injuries the recalled airbags could cause, but simply claims there's an increased risk in these particular vehicles. There's been no reported instances of the faulty airbags deploying on a customer and the original issue was found in a production test.
