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.

ABT Sportsline coming to US, premiering AS6 at SEMA

ABT Sportsline, known as ABT Tuning from its founding in 1967 until 1991, is a German aftermarket parts and tuning company that has focused on enhancing Volkswagens and Audis since the VW GTI bowed in 1978 (in Europe, at least) and races competitively in DTM (Germany's touring car racing series). The company has kept its roots in Europe for all of these years, but will debut the AS6, based on the Audi A6, at the Specialty Equipment Market Association (SEMA) in a couple weeks before opening up shop in Los Angeles in early 2014.
ABT focused on making the AS6 a balanced package by increasing engine output, tuning the suspension, giving it understated style and improving the brakes. Details are light, but the AS6's 3.0-liter diesel V6 makes 286 horsepower, a 41-hp increase over stock. Not paying attention yet? Torque jumps from 369 pound-feet to 500 lb-ft, endowing the Audi with a lot of much-appreciated low-rpm grunt. The springs are swapped out for a set of ABT units, and the body kit adds front and rear spoilers, side and rear skirts and carbon-fiber mirror covers. ABT's ER-C 20-inch wheels fit over new brakes.
We'll have more details on the car at SEMA, so stay tuned. But in the meantime, head on below to read the press release.

Tom Kristensen walks through a perfect lap of Le Mans in Forza 5

One of the best ways of learning a new track, aside from driving it, is to hear someone that's intimately familiar with it give you a good walkthrough. That's just what you'll get here, as the winningest driver in 24 Hours of Le Mans history, Tom Kristensen, walks you through the Circuit de la Sarthe's high-speed, 8.5-mile strip of pavement.
Kristensen is dubbed over scenes of drivers from a Forza Motorsport 5 contest lapping the track at the wheel of an Audi R18 E-Tron Quattro, adding a bit of visual sense to the Danish drivers description of the track.
With the 2014 24 Hours of Le Mans kicking off this weekend, this is just the sort of video you'll want to watch to get you in the mood. Take a look below, and then let us know what you think in Comments.
