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 prepping minor refresh for S6

Audi is well underway with testing for all of the refreshed versions of its A6-based sedan. We've already shown you shots of the Euro-spec A6 Allroad (which will wear some of its styling with our US-spec A6 sedan), and now we have some shots of a car that will actually arrive in the United States - the S6.
Like the Allroad, this will be quite a modest refresh, with tweaks to the headlights and taillights, as well as some slightly revised front and rear fascias. The headlights should get a new LED DRL pattern, although we doubt the changes will be much more drastic than that.
As with the Allroad, it seems likely that Audi will make a few very small changes to the interior, while the MMI infotainment system should also see an update. Changes under the hood, though, are more difficult to guess. That said, minor changes could be in store, but don't expect a dramatic increase in power or performance.

Driving the Audi E-Tron and training like an F1 driver | Autoblog Podcast #597

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder and Senior Producer Chris McGraw. First, they talk about what they love and don't love about living with the Polestar-tuned Volvo XC90 T6. Then, they talk about how much they've enjoyed driving the all-electric Audi E-Tron. McGraw lets us know what it's like to eat and train like a Formula One driver for a month, and then we tell him which Toyota or Lexus SUV he should buy.
