Mercedes shows off more of the S-Class Cabriolet

Mercedes has been very much into teasing lately, providing various kinds of peeks at the recently revealed Mercedes-AMG C63, the coming 2017 E-Class sedan, and the S-Class Cabriolet. We've seen the least of that latter car but it could be the one we know the most about. The sixth member of the S-Class family after the standard sedan, the long-wheelbase sedan, the Maybach models, the Pullman, and the coupes, this one puts a fabric top on that two-door model and then lets owners take it off. After the sketched rendering from two weeks ago, this latest photo from Mercedes shows us pretty much what we're going to get, and since we're huge fans of the coupe it looks like we'll be huge fans of this, too. It will certainly come heaped with techno gizmos like heated armrests, and a set of Burmester speakers in the tonneau cover. In case you're wondering, those screen-looking things behind the front seat headrests are fans for the Airscarf neck warming system. The press release below has a bit on the history and demise of four-seater Mercedes droptops, which helps remind us why we should care about the trim being resurrected 45 years later.

Unmistakeable, exclusive design, fine materials with maximum high-class appeal in the interior and state-of-the-art technology in the S-Class characterise the concept behind both cabriolets. "After 44 years we can again offer friends of our company an open variant of the S-Class. The new S-Class Cabriolet symbolises our passion for individual and timelessly exclusive mobility, which we share with our customers", remarks Ola Kallenius, Board Member of Daimler AG, Mercedes-Benz Cars Sales. With the new S-Class Cabriolet Mercedes-Benz is setting itself the standard of building the most comfortable cabriolet in the world. When it comes to climate comfort the enhanced automatic wind protection system AIRCAP, the AIRSCARF neck-level heating system, the heated armrests, the seat heating also in the rear plus the intelligent fully automatic climate control ensure that this is indeed the case.

Mercedes CLA facelift spotted in Germany

It's only been a couple of years since Mercedes launched the CLA-Class, but it appears the German automaker is already preparing mild revisions for the compact four-door. Spotted undergoing testing at the company's R&D center in Sindelfingen, Germany, this disguised prototype is likely packing many of the updates that were recently applied to the A-Class hatchback with which the CLA shares most of its underpinnings. As you can see, the front end is camouflaged to disguise the shape of a new grille, bumper, and headlights. Expect similar revisions to be applied to the back as well. Don't expect any drastic mechanical changes in most of the models, which will surely cut the svelte model's fuel consumption and carbon emissions incrementally. We can likely look forward to the arrival of the new AMG version that will hopefully pack the revised 2.0-liter turbo four that produces 381 horsepower and 350 pound-feet of torque in the updated Mercedes-AMG A45 – a not-insignificant boost of 36 hp and 18 lb-ft over the existing version. Mercedes won't pass up the opportunity to update the interior with new trim and equipment. That should mean a bigger infotainment screen, a new instrument cluster, and even more comfortable seats. Look for all this and more when the revised CLA arrives sometime next year, likely as a 2017 model. Related Video:

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.
