Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.

Mercedes forced to lower MPG ratings on two C300 models *UPDATE

*UPDATE: Donna Boland, manager of corporate communications at Mercedes Benz USA, told AutoblogGreen that the sticker change only applied to around 500 C-Class vehicles on dealer lots, since a new C-Class came out in late August. "About 500 are left in the United States, and we've relabeled them," she said. First Hyundai, then Ford and now Mercedes-Benz. The list of companies that have had to change their vehicles' official EPA fuel economy ratings has just grown by one with the announcement that the 2013 and 2014 C300 4-Matic FFV and PZEV versions need to have their EPA labels adjusted. The changes aren't massive, at most one mile per gallon. The changes aren't massive, at most one mile per gallon, but they are lower than before. The FFV version goes from 20 to 19 mpg in the city while the PZEV drops one mpg across the board from 23/20/29 combined/city/highway) to 22/19/28. The FFV's combined (22) and highway (27) ratings stay the same. Other Mercedes vehicles that were spot checked turned out to have accurate labels. The problem, which is reminiscent of the issues that Ford had with the Total Road Load Horsepower, was that "Mercedes underestimated the impact of aerodynamic drag and tire rolling resistance known as 'road-load,'" the EPA said in a statement you can read below. We have asked Mercedes for more information on the issue but have not yet heard back. We're not sure how many vehicles the EPA is retesting (or asking to be retested), but the agency says that the C300 models were evaluated again by Mercedes "with EPA oversight" and the EPA did its own tests at the National Vehicle and Fuel Emissions Laboratory in Ann Arbor, MI. Christopher Grundler, the director of EPA's Office of Transportation and Air Quality, said that the EPA knows that the changes are minimal, but that, "it is important that our oversight system is producing the correct results because even one MPG matters to consumers." In case you need a primer in the recent history of companies adjusting their EPA numbers, check out this and this. Based on today's news, we won't be surprised to hear more changes are coming. EPA Requires Mercedes-Benz to Correct Fuel Economy Labels for Two C300 4-Matic Vehicles WASHINGTON - The U.S. Environmental Protection Agency (EPA) is revising estimates for two 2013/2014 Mercedes C300 4-matic vehicles, the FFV and PZEV, to ensure consumers are given accurate fuel economy values.
