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.

2018 Kia Stinger vs. other luxury hatchbacks compared by the numbers

Ten years ago, if you had told us that one of the many new luxury segments to develop would be sedan-style hatchbacks, we'd have said you'd lost your mind. And yet, here we are today with not one, but four cars competing in just such a niche upscale segment: The Kia Stinger, Buick Regal Sportback, BMW 3 Series Gran Turismo and Audi A5. That's just in one size and price bracket. Two of the manufacturers listed here make larger versions of each luxury hatchback. We aren't entirely sure how it happened, but we're not going to complain, because we love the idea of a car with almost no compromise: luxury features, sporty performance, and plenty of practicality. Try Autoblog' s Car Finder to search for your next new vehicle. One of the reasons we're taking a look at these cars right now is that Kia has recently released pricing for its entry in the segment, the Stinger and Stinger GT. Buick wasn't far behind with the Regal Sportback and Regal GS, nor was Audi with the A5 and S5. So it seemed like an appropriate moment to look at the numbers and see which come out ahead or behind, with victors in each category highlighted with bold and underlined text. What we found when comparing these cars' statistics is that each one has a clear area of expertise. For performance, it's hard to beat the four-cylinder Kia Stinger and the V6 Stinger GT. The four-banger has the most horsepower of the four cars, and is just behind on torque. The V6 has the most power and torque among the six-cylinder versions. The Stingers are also the second lightest of the group when equipped with rear-wheel drive, though they fall to third with all-wheel drive. Space is a split between the Buick Regals and BMW 3 Series Gran Turismos. The Buicks have the most cargo space with the rear seats up or folded by a significant margin. The BMW on the other hand generally offers more space for passengers. It's up to you what's most important. Compare these and other potential new vehicle purchases using our tool. When it comes to cost, nothing can beat the four-cylinder Regal's base price of under $26,000. But if a V6 is what you're after, the Stinger GT is the cheapest. Neither matches the Audi A5 and S5 for fuel economy, though. Both Audis have the highest numbers for city, highway, and combined EPA estimates. Related Video:

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.
