2015 Russian Grand Prix was full of crashes and DNFs

Mercedes-AMG Petronas non-executive chairman Niki Lauda said of Lewis Hamilton's race-day domination this year, "The guy is driving like a god." Qualifying is another story, though – teammate Nico Rosberg taking pole proved that sometimes deities have to settle for second on the grid. Williams driver Valtteri Bottas surprised himself and his team with third place, half a second behind Hamilton but 0.05 sec ahead of the first Ferrari driven by Sebastian Vettel, while a mistake on Kimi Raikkonen's final flying lap left him in fifth, 0.4 sec behind Vettel. The Sahara Force India team had a good showing, with Nico Hulkenberg qualifying sixth just ahead of teammate Sergio Perez in seventh. It's the first time they've had both drivers in the top ten on the grid since the 2014 British Grand Prix. Romain Grosjean is leaving the stormy waters of Lotus at the end of the year for the unknown waters of Haas F1, but he made the shoestring operation look really good before Renault takes over by taking eighth place on the grid. Max Verstappen qualified well again with ninth in the Toro Rosso, ahead of the first Infiniti Red Bull Racing of Daniel Ricciardo in tenth. Red Bull driver Daniil Kvyat lined up eleventh for his home grand prix, certainly a disappointment after locking up fifth place on the grid last year in a Toro Rosso. When Pirelli brought soft and supersoft compounds to Sochi, the company said it hoped this year's race would be better than last year's. We're sure this first-lap mishap isn't what they meant. Rosberg and Hamilton dragged it down to Turn 1, with Rosberg getting the inside line. Hamilton had to go wide at Turn 2 as Rosberg fought to hold position, but they left a mess in their wake: Hulkenberg spun going into Turn 2 and stopped in the middle of the track, and Marcus Ericsson in the Sauber – who'd started 16th – collided with him. Both cars were out of the race immediately, and the Safety Car came in. The Safety Car returned to the pits on Lap 3 Rosberg led the field, but just two laps later the German complained of a sticking throttle pedal. Two laps later he had to retire, unable to drive the car properly. That put Hamilton at the front, and we've seen that race a bunch of times before. He built a double-digit lead and never lost it.

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 Digital Light puts a light show on the road

Soon full-featured heads up displays, augmented reality, and intelligent lighting will all work together to provide drivers with the safest and most complete picture of the road ahead. Until then, it's one advance at a time, the latest being Digital Light for Mercedes-Maybach customers. Stuttgart engineers designed a small LED with more than a million micro-reflectors for each headlight. Hardware and software control the light pattern, and paint at least nine different graphics on the road in light to warn of safety issues ahead. Digital Light evolved from the intelligent headlights demonstrated on the Mercedes Experimental Safety Vehicle in 2009 — the same ESF2009 that previewed rear belt-bag inflating seatbelts. Back then, the main beams were composed of 100 LEDs, and a brain controlled each LED to create a specific and occasionally complex lighting pattern. The new Digital Light works with all the cameras, sensors, and navigation information employed by an S-Class, and has increased resolution 10,000-fold to roughly HD quality, with a commensurate rise in the complexity of available patterns and representations. Mercedes cites numerous benefits, one being a "virtually dazzle-free main beam," another being high beams that can selectively darken so as not to blind oncoming traffic or pedestrians. Some of the projected symbols include guide lines on the road representing the width of the sedan when navigating a narrow construction zone, an arrow pointing to a pedestrian either in or very near the road, a snowflake when the temperature drops below freezing, and a chevron placed on the center line or shoulder to warn a driver when he's leaving his lane or when there's someone in his blind spot. Digital Light will first go into service with selective fleet customers for the Mercedes-Maybach S-Class this year. Considering the state of current U.S. auto regulations, we wouldn't expect to see it here for a number of years.
