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.

Race Recap: 2016 Austrian GP is mishaps from start to finish

At the 2015 US Formula 1 Grand Prix, rain mixed up the grid and a first-lap incident cast the die for the race. The Austin, Texas event made highlight reels for those reasons and because it decided the Driver's Championship. At the 2016 Austrian F1 Grand Prix, rain mixed up the grid and a last-lap incident cast the die for the race. The Spielbergring race will feature in this year's highlight reel because it might force Mercedes-AMG Petronas to make some hard decisions about the rest of the season. For the first time this season, Lewis Hamilton converted pole position into a lead through Turn 1, and began slowly pulling away from the field. Teammate Nico Rosberg started from sixth because of a gearbox penalty, but was up to third when he pitted on Lap 11. Mercedes normally pits the lead driver first, in this case being Hamilton, but Mercedes wanted to get Rosberg ahead of the two Ferraris. Hamilton pitted on Lap 22, emerging behind Rosberg because of a slow stop. Sebastian Vettel led the race for Ferrari on Lap 27 when his right rear tire exploded coming down the start-finish straight – an eerie reminder of the 2015 Belgian Grand Prix. The Safety Car rolled out, yet when racing resumed Rosberg stayed ahead. After the two Mercs came in for second stops everyone expected Hamilton to lead, but Hamilton had messed up his in-lap and lost a cumulative 3.3 seconds during his actual stops compared to Rosberg's pit-stop times. The Brit remained second. Hamilton chased his teammate for the final 15 laps. At the beginning of the last lap Rosberg messed up Turn 1 and Hamilton closed in. Rosberg took the inside line into Turn 2 as Hamilton pulled up on the outside, then Rosberg appeared to drive straight on as if he simply wasn't going to turn. Hamilton turned in, colliding with Rosberg and driving over the German's front wing. By the end of Turn 2, Hamilton had the lead and Rosberg had a broken car. The Brit won, the German puttered home to finish fourth. The incident promoted Max Verstappen to second and Kimi Raikkonen to third. Verstappen scored his second podium for Red Bull after his victory in Spain. Conversely, Raikkonen's third place for Ferrari was more gifted scraps for the scuderia. Daniel Ricciardo came fifth in the second Red Bull, Jenson Button delivered a terrific sixth for McLaren- Honda, Romain Grosjean got Haas back in the points, Carlos Sainz, Jr. secured eighth for Toro Rosso, and Valtteri Bottas in ninth for Williams.

2016 Mercedes-Benz GLE-Class First Drive

The name has changed, but the song remains, well, mostly the same. The updated 2016 Mercedes-Benz GLE-Class (nee M-Class) is all about refinement and a new attitude. Further up the range things have gone all Daft Punk – harder, better, faster, stronger. Merc's bread-and-butter SUV was last revamped in 2012, and this redesign essentially grafts the company's new corporate face and tail onto the vehicle formerly known as ML. A two-bar grille runs the expanse between stretched headlights. Above them sits a more sculpted hood with dual power lines. Below all that is a bumper with three large intakes, similar to Mercedes' sedans. The sides are untouched, but in back you'll find a new LED taillight design and trapezoidal tailpipe finishers. On the AMG Line trim pictured here, the elements rendered in chrome on the base model – like the central guard in front and diffuser panel in back – are done in black. The interior changes start with the driver staring at a new three-spoke steering wheel front-and-center, and a larger, eight-inch infotainment display on the right. That screen stands proud of the instrument panel, with two vents flanking it to remind you this isn't a clean redesign. Compare that to the freestanding tablet look, like on the C-Class, and you'll get what we're talking about. Below the big screen are the infotainment and HVAC controls that we've been looking at since 2012. The center stack newness ends there. Below the big screen are the infotainment and HVAC controls that we've been looking at since 2012. They feel really old now – perhaps because these same dials and buttons were in the E-Class sedan in mid-2009. The controls on the console, however, are overhauled, with the glossy, swoosh-shaped COMAND controller taking up residence next to the driver's arm. Beside that are a few buttons controlling functions like ride height and hill descent control, as well as the new Dynamic Select knob. This dial controls up to six driving modes. There's Comfort, Sport, Slippery, Off-Road Light, and Individual. Buyers who opt for the Off-Road Package will get a sixth mode, Off-Road+. Mercedes expects only 10 percent of GLE customers will want that capability. Every GLE comes with the basic five-setting Dynamic Select knob, no matter which of the five engines are under the hood. Here's where things get tricky, so we'll list the details for the sake of clarity.
