Audi A8 super high-tech headlight teased, whole car coming Aug 21

We have to wait one more week before we get to see the 2015 Audi A8 and S8, but it doesn't look like Audi is going to stay quiet until then. After releasing a pair of teaser videos over the last week, it has now released a first detailed picture of the new A8 revealing the trick Matrix LED headlight.
Between the high-beam and low-beam lights, the headlights contain 43 LEDs (not including those for the DRL/turn signal), but the innovative part of Matrix LED system is that a camera can control the high-beam lights - by either dimming them or shutting them off - when other vehicles are detected on the road to prevent the lights from distracting other drivers. Of course the big question remaining is if Audi can get these new headlights to pass the National Highway Traffic Safety Administration and its Federal Motor Vehicle Safety Standards. The taillights also get a cool design with 24 LEDs that use a sequential turn signal
As for the debut of the A8 and S8, we already knew the sedans would be unveiled on August 21 ahead of the Frankfurt Motor Show, but Audi finally made it officially official in a press release, which is posted below. Also be sure to check out the pair of teaser videos Audi has released for these cars recently.

Audi celebrates diesel milestone with triple-charged RS5 TDI concept

Diesels are typically slower than their gasoline counterparts, but leave it to Audi to turn that notion on its head. After dominating Le Mans and the international endurance racing scene under diesel power for the better part of a decade, the German automaker toyed with the idea of an oil-burning R8 for the road and ultimately made its first performance crossover a diesel. It's made the letters TDI a battle cry, and now it's yelling even louder with the RS5 TDI concept.
Set to be unveiled in a couple of days at the Leipzig Auto Show to celebrate 25 years of the TDI engine, the concept ditches the gasoline-burning 4.2-liter V8 in the production RS5 in favor of a 3.0-liter V6 twin-turbo-diesel with an electric supercharger added on to combat turbo lag. Output comes in at 385 horsepower and 553 pound-feet of torque, which means that while it has 65 fewer horses than the gasoline model, it packs a staggering 236 lb-ft more torque.
The result of the triple-charged madness is a 0-62 time around four seconds flat, trumping the 4.6 seconds for the road-going model. Top speed, of course, is electronically limited to 155 miles per hour, which is a bit of a shame because we bet it'd be a kick to pass a Porsche on the Autobahn in a diesel, now wouldn't it?

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.
