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.

MTM Audi RS6 Clubsport might be overkill for grocery shopping

As automotive journalists, we're biologically wired to love station wagons. We really don't have a choice. And while we prefer brown, diesel-powered, manual-transmissioned long-roofs, we suppose a 750-horsepower Audi RS6 Avant would be just dandy. This is the MTM RS6 Clubsport, and as we mentioned, it's very powerful. That's thanks to a modified version of Audi's critically acclaimed 4.0-liter, twin-turbocharged V8. While 750 hp out of just 4.0 liters is impressive, 697 pound-feet of torque is an equally big accomplishment. And if that's not enough, MTM has managed to shave nearly 200 pounds of body fat from the big wagon. Needless to say, it's very, very fast. MTM has displayed a degree of aesthetic restraint, eschewing the gaudy body kit favored by some other tuners and simply opting for a questionable paint job. The 21-inch wheels look good, although with the smattering of rubber around them, we wouldn't bet on a comfortable ride. As for the cabin, well, MTM got a bit out of hand. It's very, very orange. The seats are essentially carbon-fiber shells lined with bits of orange, leather-wrapped padding here and there. Orange, quilted-leather in the door panels, center armrest and on cushions on the side of the center console – a nice touch we wish more automakers would add to their performance cars – contrasts nicely with the black plastics and carbon fiber found on the rest of the dash and center console. That said, we aren't crazy about space for passengers, thanks to the large cage that's there to boost structural stiffness. We have a full gallery of photos of the MTM RS6 Clubsport direct from Geneva. Trust us, you'll want to have a look at this one. Related Video:

2012 Seat Exeo is Audi with the old, in with the new-ish

We know what you're thinking: This car looks an awful lot like an Audi A4. But it isn't. And it is.
Regular readers may be aware that Audi's Spanish sister-company Seat inherited the previous-generation A4 some time after it was replaced. They put some new badges on it and presto! A new flagship model for Seat.
Called the Exeo, it has now undergone a minor facelift that did nothing if not make it look even more like an Audi, if that were possible, and we got up close and personal with the new model here in Frankfurt. Check it out in our high-res gallery of live images from the show floor.
