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.

Audi R8 E-Tron back on production map thanks to new battery tech?

Contrary to our October 2012 report, it appears Audi's R8 E-Tron program is back on track, if a report from Australia is to be believed. Drive is reporting that the German brand has changed its mind and won't be sacking the program, despite previously stated concerns about the quality and price of batteries for the R8-based EV.
We last saw the R8 E-Tron prototype in the snows of northern Europe, although footage of the car has been non-existent since that wintry test. This new report claims that a small number of R8 E-Trons will see production, which gels with what we heard back in 2012 and supposed earlier this year. Apparently, some new sort of lithium-ion battery technology has allowed for a drastic increase in range, with rumors of the original 130 miles going up to around 250. According to Drive, this makes the project feasible again.
"Our engineers and technicians are further developing the car and its electric drive system. The range has grown significantly, allowing the potential for a small-scale production," an unnamed, but high-ranking Audi employee told the Aussies.

New European charging network will offer speeds up to 350 kW

It's about to get easier to fast-charge your electric vehicle across Europe thanks to four major automakers working together in a new joint venture. BMW, Daimler (Mercedes-Benz), Ford, and the VW Group (Audi and Porsche) have all signed a Memorandum of Understanding to install about 400 DC fast charging sites in Europe. As you may know, there are different types of fast chargers, but the ones that this group is talking about installing will be able to charge an EV in much less time than other stations. That's because these chargers will offer power levels of "up to 350 kW." Compare that to what's generally considered the current gold standard, the Tesla Superchargers, which have rates of up to 145 kW and a statement not that long ago from a Ford exec that suggested that 150 kW chargers would be the new normal. Of course, the Tesla chargers use the company's proprietary connector and the new network the JV is setting up will use the CCS standard. The first new stations will go up in 2017 and those 400 sites are just the beginning. A joint statement by the JV says that EV drivers will "have access to thousands of high-powered charging points" by 2020 along highways and main roads. "The charging experience is expected to evolve to be as convenient as refueling at conventional gas stations," the companies said. While not every electric vehicle will be able to take advantage of the 350 kW charging rate, the companies involved would be silly to build the infrastructure without vehicles that can handle that kind of energy flow. The JV says it would welcome participation from other automakers and will cooperate with interested regional partners.
