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.

European automakers overstate fuel economy by 40% on NEDC cycle

Volkswagen is apparently not alone among European automakers when it comes to giving out funny emissions or fuel economy numbers. It turns out that pretty much everyone across the Pond is doing it. So much, in fact, that, on average, the difference between European vehicles' fuel-economy and emissions figures and real-world driving results is about 40 percent, Bloomberg says, citing a report from Brussels-based Transport & Environment. Yes, 40 percent. Mercedes-Benz was the worst offender, as the Daimler division on average overstated its vehicles' fuel economy by 48 percent, said the study, which used data from International Council on Clean Transportation (ICCT). That automaker isn't exactly a world-beater for fuel economy in the US. In fact, two of its models, the Mercedes-Benz G 63 AMG and the G550 (pictured), showed up on the American Council for an Energy-Efficient Economy's (ACEEE) annual list of cars that are "meanest" to the environment. "The information provided by manufacturers on fuel consumption is based on the NEDC test cycle, which is prescribed by law and conducted in a laboratory. Since real driving conditions generally deviate from conditions in the laboratory, the consumption figures can also deviate from the standardized figures. Since T&E has unfortunately not published the test conditions used in its study, it is not possible to provide a useful analysis of the test results," Mercedes-Benz wrote in an e-mailed statement to Autoblog. "The data pool used also does not allow a thorough scientific assessment. Mercedes-Benz emphatically supports the introduction of the WLTP (Worldwide Harmonized Light Vehicles Test Procedure). This is supposed to replace the NEDC with the aim of bringing the rated fuel consumption and the actual consumption closer together. We also actively support the dialog between industry (ACEA) and the authorities, and are in regular contact with the EPA and the ARB in the US." The ICCT is the group that helped spur the investigation that led to the Volkswagen diesel-emissions scandal we're all still talking about, so it shouldn't expect Christmas cards from the largest German automakers this year. This new study came from data taken from about 600,000 cars. That's a lot of funky air floating over Rome. The overstatements were pretty widespread, too. The fuel-economy of the BMW 5 Series was overstated by almost 50 percent, as was the Peugeot 308's.

Ferrari's Vettel sets lap record and take pole position for Chinese Grand Prix

SHANGHAI – Ferrari made Formula One rivals sit up and take notice after an ominous show of speed in qualifying for Sunday's Chinese Grand Prix. World championship leader Sebastian Vettel took pole position with a lap more than half a second faster than that of Valtteri Bottas, the fastest of the two Mercedes drivers in third place. The German's best time of one minute, 31.095 seconds – a Shanghai circuit record – turned up the heat on a chilly afternoon with Finnish team mate Kimi Raikkonen joining him on the front row. "We thought coming into today that we would be fighting for the pole position," said Bottas, whose reigning champion team mate Lewis Hamilton qualified fourth after aborting his final flying lap. "But it was definitely out of reach today, there was nothing in the lap that we could have gained that much." "I don't know if we can challenge, we're half a second behind today," added Hamilton. "We were quicker in the race in the last race (Bahrain) but they (Ferrari) were able to hold on. They will probably do the same tomorrow." Dominant isn't a word that has been used to describe Ferrari since they chalked up five straight drivers' titles and six consecutive constructors' crowns with Michael Schumacher, but they were imperious on Saturday. The front row lockout was their second in a row after Vettel beat Raikkonen to pole last weekend in Bahrain. "Ferrari were just way too quick," said Red Bull's Max Verstappen, who was fifth fastest but a hefty 0.701 seconds off Vettel's pace. "Somehow they've found a turbo button on the straight because they are really quick and still in the corners they are reasonably quick." Verstappen's Red Bull teammate Daniel Ricciardo added, "Ferrari has had really good pace all weekend and I can't say honestly now that we're going to have their pace tomorrow, but Mercedes definitely look within reach." Ferrari's speed had already stunned rivals after Friday's opening day of practice pointed to a close battle, even if Hamilton was top of the timesheets. With temperatures plunging on Saturday, the scarlet cars seemed to come into their own. Vettel, who holds a 17-point lead over Mercedes rival Lewis Hamilton after winning in Australia and Bahrain, is looking good for a hat-trick. No driver has ever won the season's first three races without being crowned champion that year, and the last Ferrari driver to do it was Schumacher in 2004 when he was at the peak of his powers and won the opening five.
