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.

Tom Kristensen walks through a perfect lap of Le Mans in Forza 5

One of the best ways of learning a new track, aside from driving it, is to hear someone that's intimately familiar with it give you a good walkthrough. That's just what you'll get here, as the winningest driver in 24 Hours of Le Mans history, Tom Kristensen, walks you through the Circuit de la Sarthe's high-speed, 8.5-mile strip of pavement.
Kristensen is dubbed over scenes of drivers from a Forza Motorsport 5 contest lapping the track at the wheel of an Audi R18 E-Tron Quattro, adding a bit of visual sense to the Danish drivers description of the track.
With the 2014 24 Hours of Le Mans kicking off this weekend, this is just the sort of video you'll want to watch to get you in the mood. Take a look below, and then let us know what you think in Comments.

Audi RS4 Avant Nogaro Selection puts a fresh face on old memories

I've been fortunate enough to drive plenty of memorable cars over the years, and one of my all-time favorites is the Audi RS4 sedan. It was only sold in the United States for a short time, but during that quick run, it made a huge impression on me. I remember everything about that car - the smell, the sound, the exact feeling of the manual shifter as it clicked between the six gears, and the texture of the steering wheel that I so happily tossed about. In fact, whenever I'm feeling nostalgic, I go back and watch this video of the late David E. Davis, Jr., running the California Mille roads in a Sprint Blue RS4 - a video we shot for Winding Road many years ago during my tenure as an editor there.
So even though the Audi RS4 Avant Nogaro that debuts here in Geneva isn't super important, especially for our American-centric audience, I feel compelled to write about it. No, we don't get the lovely RS4 in the States anymore, but the package offered in Europe is just as sweet as ever - perhaps even more so, what with that stylish longroof shape. Under the hood is Audi's excellent, naturally aspirated 4.2-liter V8 engine, tuned to deliver 450 horsepower and 317 pound-feet of torque, allowing for a 0-62 sprint of 4.7 seconds.
The Nogaro name refers to the special blue paint - a throwback to the original Audi RS2 Avant that kicked off the company's super sweet luxury offerings. Other unique features for the Nogaro car include gloss black exhaust outlets, window frames and grille surround, as well as matte black roof rails. Special 20-inch wheels round off the exterior enhancements, and inside, Nogaro Blue Alcantara accents can be had on the door panels and seat inners.
