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.

2015 Belgian Grand Prix is a return to scheduled programming

With summer intermission over, the second half of the Formula One season commenced in the Belgian countryside at Spa-Francorchamps. After qualifying, it looked a lot like the first half of the season with just a few minor changes. Lewis Hamilton was even more dominant in his Mercedes-AMG Petronas than usual, regularly taking half a second out of his teammate in just the middle sector of the circuit. Teammate Nico Rosberg tightened it up a tad for his final hot lap, but Hamilton still took pole by 0.45 seconds ahead of Rosberg in second. With his Williams back at a power track, Valtteri Bottas got himself up to third, although more than a second behind Hamilton. Romain Grosjean in the Lotus in fourth had his best qualifying performance since his fourth-place grid spot at the 2013 US Grand Prix. This was a huge boon for Lotus, the team facing another financial issue off track that threatened to have its cars impounded as soon as they left the circuit. Grosjean had to have his gearbox changed before the conclusion of six races, however, so the five-spot penalty meant he'd actually line up ninth for the race. Sergio Perez put the Sahara Force India in fifth, where we're more used to seeing his teammate Nico Hulkenberg, just ahead of Daniel Ricciardo in the Infiniti Red Bull Racing in sixth. Felipe Massa got the second Williams in seventh, in front of the second Lotus of Pastor Maldonado in eighth. Then came the first and only Ferrari in the top ten, Sebastian Vettel qualifying ninth after a disappointing Saturday for the scuderia; teammate Kimi Raikkonen suffered gearbox issues and qualified way down in 16th. Carlos Sainz took tenth in the Toro Rosso. A new start procedure in Belgium meant drivers had to handle clutches on their own, without the engineers finely tuning bite points between the garage and the start line. That was in conjunction with another rule limiting the kinds of radio messages possible between engineers and drivers, aiming to put more of the car in the drivers' hands. After an aborted start when Hulkenberg's car quit while sitting on the grid, Hamilton made the most of the new procedure. His start wasn't amazing but he beat everyone else off the line, while those behind were alternately getting bogged down or leaping ahead. Midway through the first lap the top ten was Hamilton, Perez, Ricciardo, Bottas, Rosberg, Vettel, Maldonado, Grosjean, Massa, Marcus Ericsson. At the end of 43 laps, Hamilton would still be in the lead.

Mercedes reveals F 015 Luxury in Motion concept at CES [w/videos]

Whatever you think of the idea, autonomous vehicles are emerging as the way of the future in the automotive industry, and Mercedes is showing its vision for that driverless destiny with the F 015 concept at CES this week. Billed as Luxury in Motion, the F 015 first popped onto our radar back in October when it was snapped under wraps and then again when the German automaker released the first teaser image previewing its silhouette, but has now taken center stage at the electronics expo in Las Vegas. So what is it exactly, you ask? Well, aside from being entirely autonomous – bringing together a suite of advanced technologies to take the driver out of the equation – it's also big. It's marginally larger than an S-Class, in fact, and with a more spacious one-box form that turns the cabin into a rolling living room. That's where you'll find four individual bucket seats that swivel towards each other, and pivot towards the giant doors for ease of ingress and egress. The doors open a full 90 degrees and the back ones swing suicide-style like on a Rolls-Royce, but without a B-pillar to get in the way. An array of six display screens turn the cabin – clad in wood, aluminum, glass and leather – into an all-enveloping "digital arena," with gesture-based controls, touch-sensitive screens and eye-tracking technology. Made of carbon fiber, aluminum and high-strength steel, the concept is some 40-percent lighter than a conventional automobile of its size. And while Mercedes isn't saying exactly what would provide the motivation (and to what effect), it does state that "the bodyshell of the F 015 Luxury in Motion was designed to allow the impact-protected integration of an electric drive system with fuel cell." The concept follows the debut of the Future Truck 2025 concept big-rig at the IAA Commercial Vehicles show in Hannover a few months ago, and is earmarked to make transportation through and between the world's growing cities a smoother, safer and less human-intensive ordeal. Whether that's the kind of future you want to live in is another matter, but you can scope it out in the videos and press release below and in the extensive gallery of images above for a closer look.
