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.

Mercedes has already booked 30k orders for new S-Class

When Toyota snags 30,000 Corolla orders over a three-month span, it's entirely possible we're in the midst of a global economic collapse and that the end is nigh. That's because the scale for Toyota is so very large. Mercedes-Benz, on the other hand, operates on a much smaller scale, particularly when we talk about its higher-end models, like the S-Class.
In 2012, Mercedes sold 65,000 of its flagship sedans in Germany and the EU. That's 178 units per day, for 365 days. Based on that, you can imagine the excitement at Stuttgart when it accepted 30,000 orders for the new S-Class in just three months. That's an average of 333 per day on a continent with a notoriously shaky economy. Now, admittedly, this enthusiasm could wane as the refitted S-Class becomes more common and Mercedes achieves market saturation in Europe's many chauffeur and livery services, but Mercedes isn't choosing to look at it that way.
"The new S-Class has already jumped back into the lead in terms of new vehicle registrations in Germany and its neighboring European countries," Mercedes-Benz head of sales and marketing, Ola Kaellenius, said in a statement last week.

2016 Mercedes-Benz GLC250 Quick Spin

The 2016 Mercedes-Benz GLC is an all-new luxury crossover that replaces Benz's compact GLK. We're driving it right now, and will have a full first drive soon. But before this, we were granted some early access on a drive from Lithuania to Latvia – just enough to form some initial impressions. As part of Mercedes' expansion with new models (and old models taking on new names) the GLC will no longer be the entry-level CUV for Mercedes – that title has been assumed by the GLA crossover. The GLC moves up not only in the hierarchical range, but grows 4.6 inches in the wheelbase, and is more roomy overall. Most evident, the GLC gets completely new styling, something that is immediately clear upon first glance. Mercedes says the 2016 GLC represents the future design direction for all its SUVs. Continuing the "Sensual Purity" design language of the new S-Class and C-Class, our Euro-spec GLC prototype is curvier, cleaner, and more modern than the more rugged-looking GLK. Mercedes says the US will have standard front and rear bumpers optimized for off-road use, with a 28-degree approach and departure angles for all variants. Despite boasting four doors, the GLC has a coupe-like silhouette. Our model's LED headlights, chrome-finished dual exhaust pipes, and large wheels (up to 20-inches) add to this sporty aesthetic. The real story however, is on the inside, where the GLC mimics the striking interior of the C-Class. Based on our model's open-pore wood, flowing center console, and brushed metallic and piano-black finishes the GLC boasts the nicest interior in the class. With a few short hours spent evaluating Benz's new ute – and evading endless Baltic speed traps – we were able to get some immediate impressions. There's a lot to like here. Driving Notes The 2.0-liter four-cylinder engine is rated at 241 horsepower and 273 pound-feet of torque. But what the driver actually experiences will depend on the five different driving modes. A simple toggle switch on the center console by the MMI touchpad and scrollwheel moves you through the various modes: Eco, Comfort, Sport, Sport Plus, and Individual. Each mode represents a marked difference in steering feel and throttle response. Eco and Comfort modes are fine for driving around town, but lack any semblance of sportiness. Sport and Sport Plus improve feedback, but the GLC never feels quick in any mode. It does feel nimble, and the drive is more car-like than SUV, which bodes well for the majority of US customers.
