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.

Rosberg survives the Mexican mess | 2016 Mexican Grand Prix recap

Roughly ten messy laps defined the Mexican Grand Prix – five laps at the start and five at the end. Those laps included a couple of actual wrecks and a few more near wrecks that turned the entire day into chaos. To have any chance of winning the 2016 Driver's Championship, Lewis Hamilton needed to get his Mercedes-AMG Petronas across the finish line ahead of teammate Nico Rosberg. Once again we got a weekend full of vintage Hamilton, the Brit dominating the from Friday to Sunday, except for the first corner of the first lap. Pole-sitter Hamilton reached Turn 1 clearly in front of the field. But he couldn't make the corner and stay on track, so he zipped into the runoff area and over the grass, rejoining at Turn 3 still ahead of the field. The stewards didn't penalize Hamilton, one commentator's explanation being that Hamilton "was not battling another car." The non-action left car #44 to enjoy a lights-to-flag win. At that very same corner, Rosberg also availed himself of the runoff area. His infraction seemed destined to incur a penalty until replays showed that Max Verstappen in the Red Bull slid wide and bumped Rosberg, causing the German to go off track. No penalties were handed out there, either. Verstappen would return to hound Rosberg later in the race when angling for second place. Verstappen took a stab through Turn 4 on Lap 50 of the 71-lap race, but ran off the track and lost touch with the Mercedes by Lap 55. Ferrari got half of its strategy right in Mexico, putting Sebastian Vettel hard on the charge in the final stint. The German got within DRS range of Verstappen on Lap 67, with Red Bull's Daniel Ricciardo a little more than a second behind Vettel. On Lap 68, Verstappen pulled the same move as Hamilton at the beginning of the race: the Dutchman ran wide through Turn 1, zoomed over the grass and rejoined the track at Turn 3, staying ahead of Vettel the whole time. With three laps remaining, the stewards chose to investigate after the race. In spite of Verstappen's own team telling he probably needed to cede position to Vettel, Verstappen stayed in front and slowed just enough to put Vettel under threat from Ricciardo. On Lap 70 Ricciardo had closed up to Vettel's gearbox. Headed for Turn 4, Vettel swung outside to take the corner. When Ricciardo moved inside to pass, Vettel moved inside to block the Aussie while both cars were in the braking zone. The Ferrari made light contact with the Red Bull, but Vettel held his position through Turn 5.

The Vision Mercedes-Maybach 6 is pure electric excess

The Vision Mercedes-Maybach 6 is a two-door, two-passenger coupe that spans over 18 feet long. Everything about this car is more than you need. But isn't that the true definition of ultimate luxury? With so much sheet metal, it can be tricky to get everything to look right, but Mercedes seems to have done nicely with this concept. Overall, the car's long nose and short deck are reminiscent of the Mercedes-AMG GT, and the long, tapering tail and lights are similar to that of the Mercedes-AMG Vision Gran Turismo concept from a few years ago. Capping off the front of the Mercedes-Maybach 6 is a proud, prominent grille that the company claims was inspired by a pinstripe suit. At each corner are 24-inch wheels with transparent panels based on the transforming, aerodynamic wheels of the Concept IAA Mercedes previously showed. Powering this massive coupe are four electric motors that can produce a combined 738 horsepower. Mercedes says that will be enough to get the car to 62 mph from a standstill in under 4 seconds. The motors are backed by an 80 kWh battery that the company says can propel the car up to 200 miles. Perhaps more interesting than its range is the fact that the Mercedes-Maybach 6 can pick up a charge worth 62 miles in just 5 minutes, assuming you've got the right charger. This is technology that could really make a difference in the day-to-day practicality of electric cars, provided that it makes it to reality. The car can be charged either by being plugged in, or wirelessly with an inductive charging system. Inside, the Vision Mercedes-Maybach 6 has even more fantastical features. It does retain analog gauges as a link to the past, but augments them with wrap-around glass trim that doubles as a display and touch-sensitive interface. The windshield seems to be pulled from Mission Impossible with its ability to display information. Sensors in the seats are designed to read the condition of the passengers and even their outfits to custom tailor everything from lighting to massage features. It's hard to say what the production odds are for this mega Mercedes, but you probably shouldn't hold your breath. Even for the rarified segment of seven-figure cars, this would be pretty extravagant. It wouldn't be impossible, or without precedent. Back when Maybach was still its own brand, the company created a ridiculous luxury coupe called the Exelero, and they sold the fully-functional car.
