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and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation.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

Audi bringing matrix 'organic' LED concept to Frankfurt

Audi has announced that it's bringing a new concept to the upcoming Frankfurt motor show in September, and now it is teasing the taillights. They adopt organic light-emitting diode technology, which takes advantage of several benefits. For one, it uses a relatively low amount of electricity, between three and four volts. It's also incredibly thin, made up of two layers, each less than a thousandth of a millimeter thick. It casts no shadows, requires no reflectors or any other elements, and emits very little heat. Plus the lights can be formed into different shapes, opening up new possibilities for designers. This isn't the first time we've seen Audi focus on lighting technology, and in recent years it's showcased matrix LED and matrix laser headlights. The company runs through the history of the evolution of its lighting tech in the video above. We'll have to wait a little longer to find out what the team from Ingolstadt will be putting these new taillights on. Audi presents latest lighting technology at the IAA in Frankfurt - Matrix OLED technology makes its debut in a concept car at the IAA - Light attains a new level of homogeneity - Flat light sources open up new design possibilities Audi is presenting its next step in automotive lighting technology at the IAA in Frankfurt. The new Matrix OLED lights enable a previously unattainable level of lighting homogeneity, opening up further creative opportunities for design. As the leading brand in automotive lighting technology, Audi has systematically developed all aspects of OLED technology over the years. Matrix OLED lights combine high-tech engineering and design ideally – initial projects are currently underway to implement OLED technology in production tail lights. They are being shown for the first time in a concept car at the IAA. OLED is an English acronym for "organic light emitting diode." In each OLED unit, two electrodes – of which at least one must be transparent – incorporate numerous thin layers of organic semiconductor materials. A low DC voltage – between three and four volts – activates the layers, each of which is less than one-thousandth of a millimeter thick, to light them. The color is based on the molecular composition of the light source. In contrast to point light sources – such as LEDs – which are made of semiconductor crystals, OLEDs are flat light sources. Their light attains a new level of homogeneity, and its dimming is continuously variable.

Automakers need to stop stalking celebrities

Since the invention of the automobile, cars and stars have gone together like paparazzi and the Kardashians. During this season of starlet-adorned award ceremonies, from the Golden Globes through to the Oscars, you will find a lot of car companies all vying to loan out their vehicles to any celebrity with a recognizable face who happens to be heading to a red-carpet award ceremony. There is, however, none so coordinated, consistent and aggressively playing the Fame Game as our friends at Audi. Since the invention of the automobile, cars and stars have gone together like paparazzi and the Kardashians, so by association getting a celeb behind the wheel of your car brand gives it an instant image boost that must make the car more attractive to buyers. Celebrity tales equals dealership sales. That's the logic, anyway. But surely the millions of dollars spent giving free cars to rich stars is a waste of precious and increasingly smaller marketing budgets. It's time to make the car the star, not the other way around. Lets be clear, we are not talking about the very obvious dropping of famous faces into big budget ads. That has its place in the marketing toolbox, but in a very media savvy world it's clear most of us get that play-for-pay concept. Today, the use of just a famous name in an ad yields very little influence on whether you or I will buy that car. No, this awards-ceremony loaner deal is a subtler, but higher risk, idea that if you see a "star" with "their" car in "real life" then surely that adds to the car's appeal. We, the audience, are expected to start salivating like Pavlovian puppies in our desire to have same car in our own, less red-carpeted driveway. Geoff Day has been called the "Pied Piper" of the auto industry, leading auto journalists on wild rides around the globe in his position as former director of communications for Mercedes-Benz USA. Before that, he worked at DaimlerChrysler UK on its PR efforts, and rubbed elbows with the Queen of England in his role at the Buckingham Palace Press Office. His phone is filled with the numbers of the great, the good and the bad. His head is filled with dirty little secrets hiding in many corners of the auto industry. There is no doubt that the publicity that comes with a well placed story, picture or feature can help raise awareness of a product – Oprah proved that with her "Favorite things" – especially if you are launching a line of wrinkle cream or juice bars.
