Audi celebrates 25 years of TDI

Nope, the diesel engine never really did go out of style for Audi. Now, the German automaker has released a video reminding the world of its persistence with the oil-burners and is commemorating the Silver Anniversary of Audi's first commitment to turbodiesels in 1989. And, yes, there are some road racers shown in the clip, so some of those bad boys actually move pretty well. Audi engineers on camera admitted to some of the early TDI engines being "slow" but still valuable for their torque and, obviously, their fuel economy relative to gas-powered engines. A bunch of tinkering later, though, and Audi says its diesels can be a legitimate "part of a performance car" and has even overcome the issue of noisiness that's often associated with diesels. The automaker made some news in these parts a few years back when its Audi A3 TDI won the 2010 Green Car of the Year at the annual LA Auto Show in late 2009, and the model even succeeded a fellow diesel (the Volkswagen Jetta TDI) to boot. Granted, diesel sales aren't nearly as popular in the US as they are in Europe. Still, Audi last year boosted its diesel sales in the US by 40 percent to 10,076, which was about a tenth of what sister company Volkswagen sold in diesels last year in the States. And things have looked even rosier this year for Audi's TDI sales. Through June, Audi diesel sales have almost quadrupled from a year earlier to more than 8,100 units. Check out the 150-second video on Audi's 25-years of TDI production below.

Delphi plans automated-driving journey across the United States

Delphi is attempting to become the first company to pilot an automated car across the United States. The global automotive supplier will start a cross-country journey from a location near the Golden Gate Bridge in San Francisco starting on Sunday, March 22, and cover approximately 3,500 miles on a trip to New York, where it will arrive sometime during the New York Auto Show. Along the way, Delphi engineers will gather data on how the car, an Audi SQ5, performs in a variety of road and weather conditions that the company says could only be tested in a real-world environment. "Delphi had great success testing its car in California and on the streets of Las Vegas," said Jeff Owens, the company's chief technology officer. "Now it's time to put our vehicle to the ultimate test by broadening the range of driving conditions." A formal announcement is expected tomorrow during the SXSW festival in Austin, TX. The company recently demonstrated many of its advanced-safety and automated driving technologies during CES, driving in Las Vegas. The cross-country trip will include tests on its radar, vision and advanced-drive assistance systems, certain vehicle-to-vehicle and vehicle-to-infrastructure communications, and intelligent software, which includes automated highway pilot with lane-change technology, automated urban pilot and automated parking functions. Though a driver will be behind the wheel throughout the journey, Delphi says its active safety technologies can make complex decisions, like stopping and proceeding at four-way stops, timing highway merges and calculating safe maneuvers around bicyclists. While California has certain motor-vehicle laws that help regulate autonomous vehicles, it was unclear whether Delphi needs special arrangements or permission from other states to conduct automated-vehicle testing elsewhere – or if those concerns might be negated by an active driver. Earlier this year, Audi turned heads at CES by driving an A7 from San Francisco to Las Vegas in a similar display of automated-driving technology.

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.
