Mercedes-Maybach GLS prototype caught testing with its big new grille

The new Mercedes-Benz GLS is a massive tech fortress on wheels, so the Maybach GLS is bound to be a massive tech castle. Last we heard from the gigantic Benz SUV was that it was going to be built at Mercedes’ Alabama plant. With a starting price expected to be around $200,000, itÂ’ll probably be the most expensive vehicle produced in the U.S. These spy shots give us an idea of what weÂ’re going to be looking at when the production SUV is finally revealed. Our first hint that this prototype is a Maybach is the grille. It looks suspiciously similar to the grille on the Vision Mercedes-Maybach Concept with all the vertical slats running down the big maw. Minimal camouflage is disguising the exterior for the most part, but we imagine Mercedes is hiding any of the gaudier parts of the car itÂ’d like to save for a big reveal. The exhaust outlets sure do look a bit different than the regular GLS, but the outside is generally the same as what we see today. As for the interior, thatÂ’s where most of the magic is expected to happen. A significantly overhauled look is inevitable, with the focus on even more luxurious materials than the most expensive norm-core GLS. A rear seat that's fit for a king or two is likely, along with Maybach-exclusive tech to boot. For now, we canÂ’t see in the heavily camouflaged and taped-off windows, leaving us to wonder about the luxury within. This Mercedes-Maybach is expected to compete with other massively expensive SUVs like the Bentley Bentayga or a fully decked-out Range Rover.  Everything thatÂ’s optional on the GLS should come as standard here, including the trick E-Active Body Control suspension. Look for a reveal coming in the not-so-distant future, as this prototype doesnÂ’t look terribly far from production to us.

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.
