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and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation.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.

How Audi will make roads friendlier to autonomous cars

Today, Audi announced some of the new projects it will be implementing on Germany's Digital Motorway Test Bed, which comprises a few sections of highway on which the government and industry can test autonomous and connected tech. Among Audi's projects is one specifically aimed at making roads easier for autonomous cars to navigate. Audi is looking to make the road and other objects more visible. The company has been researching materials that could make guardrails and road markers reflect radar waves more readily, and Audi will install test versions soon. The goal here is to help make these objects easier for the autonomous vehicle's sensors to see in inclement weather, and at greater distances in good weather. The company will also test additional road markings that will be easier to see for onboard cameras and will help the car place itself on the road. Audi will also try out new vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) technology that will be able to alert cars to speed limits, traffic conditions, ice patches and possibly allow for driving patterns such as platooning. This will be a significant step above the traffic light communication system Audi has released in select areas. The company will also be working on very detailed mapping of the area. Audi claims it will be accurate down to the centimeter. From what we've seen at MCity, the world as it stands presents all kinds of difficulties for autonomous vehicles, from worn-out signs to rough pavement. So any advances that make it easier for autonomous cars to see and communicate should help bring such vehicles to reality much sooner.

Audi R8 Exclusive Edition gets laser beam headlights

We've long lamented the National Highway Traffic Safety Administration's draconian Federal Motor Vehicle Safety Standards, which contrary to their name, have actually prevented automakers from selling some substantial and important safety equipment, like advanced headlights, in the US market. Until now, apparently. To be fair, we've known Audi was prepping its advanced laser headlights for the US market, but that doesn't make their arrival any less exciting. Audi will begin offering DOT-approved high-beams that use advanced laser diodes on a limited run of V10-powered R8s. Exclusive to the, um, Exclusive Edition R8, the advanced lamps complement the standard LED low beams and dynamic front turn signals, offering "very bright and pure white light" for 25 lucky consumers. Here's some more techno babble about how the lights work – according to Audi's official release, there's a laser module in each headlight containing four high intensity laser diodes that fire out blue lasers. Then, a phosphor converter adjusts the 450-nanometer laser into visible light that fires up above 40 miles per hour. "When conditions permit," Audi's release reads, the laser high beams "greatly enhance visibility for the driver by projecting a low and wide beam of light on the road ahead." Naturally, we have questions, but Audi wasn't keen on releasing much info ahead of the R8 Exclusive Edition's Los Angeles Auto Show debut. The company confirmed that the new lights are DOT approved, which makes sense considering the LA introduction. We're also wondering how Audi's new Laser Lights differ from BMW's similarly named Laserlight system, offered on the i8. Both setups use lasers to replace conventional high beams, but BMW says it "adjusted to the maximum allowable light output for the US market." Audi was cagey about explaining if it modified the system to satisfy the feds. Ingolstadt also offered the typical "we don't comment on future product" when asked about future applications for its laser headlight technology. Beyond the advanced high-beam headlights, the R8 Exclusive Edition comes standard with Quantum Grey paint, 20-inch "Y Design" wheels, a carbon-fiber side blade with an orange stripe, and a whole bunch of interior trim upgrades, like full leather upholstery and Alcantara trim. Price start at $229,200, not counting $1,250 in destination charges. We'll have more on the R8 and its laser lamps when it debuts in a couple weeks. Related Video:
