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.

We demo Audi's Traffic Jam Assistant tech on the road [w/video]

The closer automotive technology comes to making good on the promise of fully driverless vehicles, the better we see just what difficult work reaching that ultimate goal will become. That's because, unlike so many other in-car technologies that need only integration into a vehicle, truly autonomous cars will also insist on involvement with the surrounding environment, fellow motorists, infrastructure in cities and other communities and making it all work without exposing automakers to law-breaking or tremendous possible litigation. Clearly that isn't all about to happen in one go.
At CES in 2012, Audi told us about a debuting technology that would mark a significant step along the path towards self-driving cars: Traffic Jam Assistant. This year, the German automaker invited us out to Las Vegas to see the jam-busting technology in action, on a relatively busy freeway.
The Traffic Jam Assistant (we're pretty sure that name is still in Beta) promises to relieve drivers from the tedium of slow-moving freeways by taking care of braking, acceleration and staying inside of the lane - all with no input from the human behind the wheel. While still a fair step from truly autonomous driving, the goal here is to give a commuter some respite from the mechanical, time-wasting traffic jam paradigm, potentially opening up a space for productivity in the process. (Audi can't come right out and say that TJA will allow you to use your cell phone in traffic, as that's still against the law in many places, but something like that is clearly on the radar... er... LiDAR.)

Porsche hybrids come up short at Le Mans

Two cars, one finish, zero victories. That's a brief synopsis of Porsche's hybrid-vehicle performance in the 24 Hours of Le Mans race in France. There's always next year. Porsche entered two 919 Hybrid vehicles in the race. The No. 14 car essentially limped to the finish line after encountering drivetrain problems. The other Porsche hybrid, No. 20, was driven by Germany's Timo Bernhard, New Zealand's Brendon Hartley and Australia's Mark Webber. That car ran for more than 22 hours before its own powertrain issues did that racing team in for good. Both vehicles ran towards the front of the pack at times during the race, and the No. 20 car actually led the race after about 20 hours. Still, both teams said they were disappointed in the results. Porsche sister company Audi came up big for the 13th time in the race's long and storied history. One Audi R18 E-Tron Quattro won the race, while another finished second. The Toyota that had pole-position and was winning much of the race shut down after 15 hours of racing because of electrical issues and Nissan had trouble with is ZEOD RC. Check out Porsche's press release below, and read here for a more general race recap. STRONG PERFORMANCE BY PORSCHE 919 HYBRIDS BUT NO DREAM ENDING IN PROTOTYPE RETURN TO LE MANS Le Mans. After a strong performance by both Porsche 919 Hybrids, the Porsche Team was left empty-handed after a dramatic final stage of the race. Following more than 22 hours, car No. 20 driven by Timo Bernhard (Germany), Brendon Hartley (New Zealand) and Mark Webber (Australia) suffered a powertrain problem at the world's most famous endurance race, the 24 Hours of Le Mans. Earlier in the race the LMP1 class car was leading overall for a significant period of time. The second innovative and highly complex prototype – in the hands of Romain Dumas (France), Neel Jani (Switzerland) and Marc Lieb (Germany) – likewise proved to be very competitive, but was hampered by a drivetrain problem. However, their No. 14 car crossed the finish line under its own power. After a thrilling start to the race with changing weather conditions, numerous accidents and a relatively calm night, Bernhard took the overall lead in the No. 20. The longtime Porsche factory driver returned to the top spot after 20 of the 24 hours. At 12:36 (CET) on Sunday, he handed the leading car over to Webber. Less than 20 minutes later the Australian was forced to slow down and drove solely on electric power back to pit lane.
