Hackenberg says next Audi A4 set for Frankfurt debut

The current Audi A4 is among the oldest vehicles in the brand's lineup. Having debuted back in 2008, it's long overdue for an update, and according to our friends at Indian Autos Blog, that'll happen in roughly six months. IAB spoke to Audi research and design chief Ulrich Hackenberg, who indicated that the fifth-generation A4 will be shown at the 2015 Frankfurt Motor Show in September. The new sedan will be unveiled in "a pre-presentation" before the auto show itself, Hackenberg told IAB, adding that "you'll be happy to see it." Information beyond that, though, remains sparse. Based on our previous spy photos, we expect the new A4 to ride on the Volkswagen Group's modular MLB Evo platform that's been stretched to accommodate a larger wheelbase. The styling, meanwhile, will be more evolutionary, inspired in part by the new TT. Expect more on the next-generation A4 as September approaches. Related Video:

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.

Recharge Wrap-up: BMW i3 carshare, Audi e-gas plant

Elix Wireless has announced its E10K Wireless Charging System. The system is designed for harsh conditions, delivers up to 10 kilowatts and features automatic detection and removal of foreign objects. Its low frequency makes it safe to operate near oil and gas, and in other hazardous environments. The system can charge personal vehicles, as well as electric buses, trucks, mining equipment and heavy duty machinery. Elix has "created an entirely new technology that meets customer demand for fast, safe and reliable charging," says, CEO David Smith. The E10K system uses Elix's Magneto-Dynamic Coupling technology, with rotating permanent magnets in the transmitter and receiver. Read more at Green Car Congress, or in the press release from Elix Wireless. FreeWire Technologies and Siemens are working together on a pilot program for the Mobi Charger. The mobile charging station, which uses second-life EV batteries to charge electric vehicles, will be deployed for a trial at LinkedIn's campus in Mountain View, CA. The Mobi is more flexible than stationary chargers in that it brings the charging to the car, regardless of where it is parked, rather than having to park the EV in a specific spot. It can charge up to five cars per day without putting stress on the grid during peak hours. Read more from Siemens. Audi's e-gas plant in Werlte, Germany helps stabilize the power grid. The plant, which produces synthetic methane using CO2, water and electricity, is able to draw six megawatts of power within five minutes, allowing it to become certified in the electricity balancing market. This helps the grid adapt to the larger load fluctuations that go hand-in-hand with generating renewable energy. It also allows the plant to achieve higher operating times and produce more e-gas each year. Read more in the press release from Audi. The BMW i3 is now available through the DriveNow carsharing service in Germany. DriveNow, which is a joint venture between BMW and car rental company Sixt, has put 100 i3s into service in Berlin, Hamburg and Munich. BMW also says that it supports a shift away from private car ownership in order to improve urban living and mobility, and sees electric carsharing as an important part of that. "We are witnessing the changes our customers and society as a whole are making and we are taking them on board," says BMW's Dr. Bernhard Blattel.
