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and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation.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

For Audi, Quattro name means something for hydrogen cars, too

Forget Dueling Banjos. Audi is proposing "Dueling Motors" for its Audi A7 Sportback H-Tron Quattro concept vehicle. All in the name of appropriate pickup, of course. The German automaker, which showed off the concept sedan at the Los Angeles Auto Show last month, is pairing a plug-in electric motor with a hydrogen fuel cell powertrain. Each motor powers two wheels, maintaining the Quattro's all-wheel-drive pedigree. The car's 8.8-kWh lithium-ion battery can drive the car as far as 31 miles on battery-power alone. After that, the water-vapor-spewing fuel-cell engine kicks in. Audi executive Ulrich Hackenberg told Automotive News Europe that the unusual set-up is necessary because the hydrogen fuel cell powertrain alone would only power two wheels while providing an insufficient 136 horsepower. Not exactly sport-sedan material, especially for a car that weighs about 4,300 pounds, even if it is a zero-emission ride. Combined, the two engines give the sedan 231 horsepower as well as a combined single-charge/full-tank range of almost 350 miles. What it all means is that the A7 can go from 0 to 60 miles per hour in less than eight seconds and has a top speed of about 112 miles per hour, and can still dash through the snow.

Audi re-illuminates Sport Quattro with Laserlight concept for CES

Automakers typically spend months working on a concept car, then unveil it at a car show and move on to the next. But Audi has demonstrated a propensity at refining the same concepts and bringing them back for more. Just look at how many time Audi iterated its E-Tron concept, and how many diesel R8s it toyed with. It brought the Italdesign Parcour out of retirement and rechristened it the Audi Nanuk, and it's been doing the same with the Quattro concept for the past several years. The German automaker rolled out the first Quattro concept back in 2010, and followed up with the reborn Sport Quattro concept less than a year ago. And now it's preparing to unveil yet another.
Called the Sport Quattro Laserlight concept, this time it's not as radical a departure from the Sport Quattro concept as that was from the first Quattro concept. In fact, there's really only one vital difference. That'd be the laser headlights "that leave all previous systems in the dark," according to the press release below. The system uses matrix LEDs around the outside of the element as low beams, and lasers on the inside for high beams. Measured in mere microns, the laser diodes are significantly smaller than LEDs, while lighting up the road ahead for nearly half a kilometers (1,640 feet), providing twice the lighting range and three times the brightness of LED high beams.
Otherwise the concept car you see here and which Audi will display at the Consumer Electronics Show in Las Vegas next week is essentially the same as the one it showed in Frankfurt this past September. It's got the same measurements, wearing the same CFRP bodywork, with the same interior and the same 700-horsepower hybrid powertrain, only the yellow exterior has been repainted Plasma Red and the black interior redone in a more low-key Slate Grey, as you can see from the high-res image gallery above.
