The skinny on Delphi's autonomous road trip across the United States [w/videos]

Rolling out of an S-shaped curve along Interstate 95, just past Philadelphia International Airport, the final obstacle between the autonomous car and its place in history appeared on the horizon. So far, the ordinary-looking SUV had traversed the United States without incident. It had gone through tunnels and under overpasses. It circled roundabouts and stopped for traffic lights. Now, on the last day of a scheduled nine-day journey, it was poised to become the first autonomous car ever to complete a coast-to-coast road trip. First, it needed to contend with the Girard Point Bridge. Riding in a rear seat, "I saw that bridge coming, and I thought, 'Oh my gosh, this is going to be a grab-the-wheel moment," said Kathy Winter, vice president of software at Delphi Automotive. The car, an unassuming Audi SQ5 nicknamed Roadrunner, had been well-tested. Back in January, a few inebriated pedestrians fell flat in front of the car during a demonstration in Las Vegas. It was the quintessential worst-case scenario, and the car admirably hit the brakes. More than drunken louts, bridges present a sophisticated challenge for the six radar sensors that feed data to the car's internal processors. Instead of sensing solid objects, radar sensors can read the alternating bursts of steel beams and empty space as conflicting information. "They're a radar engineer's worst nightmare," said Jeff Owens, Delphi's chief technology officer. Girard Point Bridge, a blue skeleton of girded steel that spans the Schuylkill River, might be a bigger challenge than most. Traveling across the lower level of its double decks, the autonomous car's radar sensors had to discern between two full sets of trusses. Cross the Schuylkill, and Delphi's engineers felt confident they'd reach their destination: the New York Auto Show. For now, the sternest test of the trip lay directly in front of them. A Data-Mining Adventure Until that point, the toughest part of the journey had been finding an open gas station in El Paso, TX. Trust in the technology had already been established. The main reason Delphi set out on the cross-country venture with a team of six certified drivers and two support vehicles was to capture reams of data. What better way to do that than dusting off the classic American road trip and dragging it into the 21st century? They did exactly that, capturing three terabytes worth of data across 3,400 miles and 15 states.

2014 Audi A4 next car to go on big diet while adding features

The Audi A4 is expected to receive a major redesign over the next couple of years, and with the smaller A3 now gaining a sedan model, it is being reported that the A4 might be getting a little breathing room for a more advanced design and improved technology and features. According to AutoBild, this would include a drop of more than 200 pounds in curb weight, updated cabin tech and a wider variety of drivetrain options.
AutoBild states that Audi is looking to upgrade just about every detail - inside and out - when it comes to the 2014 Audi A4, and this includes a next-generation MMI system that uses two digital displays. Extensive use of magnesium, aluminum and plastics will help shave an estimated 220 pounds from the A4's curb weight, and in terms of engines, it sounds like the usual array of forced-induction, small-displacement gas and diesel engines will be on tap, but a bigger V6 TDI and a plug-in hybrid powertrain are also mentioned.

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.
