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.

Audi recalls 850,000 A4 models globally for airbags that won't deploy

Audi has announced that it will be recalling 850,000 A4 sedans, wagons and Allroad models across the globe due to a software problem that could prevent the front airbags from deploying. All 850,000 vehicles were built after 2012.
Audi has already adjusted production of new A4s to eliminate the software glitch. Meanwhile, the German manufacturer was quick to emphasize that Takata did not manufacture the affected airbags.
According to Reuters, 250,000 of the affected A4s were built for the Chinese market, while another 150,000 were sold in Germany. Audi didn't provide a breakdown beyond those two countries, although it'd be a surprise if there weren't at least some affected airbags in the US market.

Xcar weighs in on the five best-sounding modern cars

Getting behind the wheel of a well-balanced vehicle can be a wonderfully visceral experience, thanks to the combined feeling of things like the weight of the steering, the bite of the brakes, and, of course, the roar of the engine. Unfortunately, many of the sensations of driving require actually being in the driver's seat to understand them, but thankfully the intoxicating noise of a beautifully tuned internal combustion engine can be shared with everyone. In a new video, Xcar shares their opinion on the five best-sounding modern performance cars. The list is a symphony of horsepower. As opposed to keeping all of the vehicles brand new, Xcar actually picks a few that are recently off the market. They're all definitely champs, though. While the list itself is well stocked, you might be able to argue with the specific order, and it would be nice to hear a few participants from outside of Europe for a collection like this one, too. No matter. Every listener is sure to find something they like in the bunch, though. Turn up the volume and enjoy.
