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.

2014 Audi S1 is a little hatch hiding huge power [w/video]

The Audi S1 takes the Four Rings' high performance brand to its smallest model yet. Offered in three- and five-door forms (pictured above), the S1 is a subcompact hot hatch that seems specially suited for Europe's dense cities and tight roads.
The S1 follows the rest of the Audi S vehicle lineup with a very understated design. It maintains the looks of the standard car, but the larger air dam, 17-inch wheels and side sills tells viewers that something mean is lurking under the surface as well. It packs the Volkswagen Group's ubiquitous 2.0 TFSI four-cylinder, tuned here to produce 228 horsepower and 279 pound-feet with a six-speed manual transmission and all-wheel drive, and it is enough to get it to 62 miles per hour in less than six seconds for either body style and to a top speed of 155 mph. Handling is aided by a more sophisticated four-link independent suspension to replace the standard A1's torsion beam setup.
They come in just two colors for now - Vegas Yellow or Sepang Blue - and are hitting European roads later this spring. UK prices start at £24,900 ($41,518) for the three-door and £25,630 ($42,735) for the five-door.

VW says it has sold over 100,000 TDI diesels in America this year

Volkswagen Group of America has lit oil-burning fireworks to celebrate the sales of more than 100,000 TDI Clean Diesel vehicles in the US between its VW and Audi brands this year. According to VW, that means it is responsible for more than 75 percent of diesel-engined cars and SUVs sold here - perhaps not surprising when the two brands offer a total of 12 diesel models.
What might be surprising is that the number of diesels isn't far off the estimated sales of 90,000 battery electric vehicles and PHEVs, with 15,000 of those accounted for by the Tesla Model S, another 12,000 or so being the Toyota Prius PHEV.
VW's keen to play up the ease of making diesel part of your life, stressing that it doesn't need any change to the refueling infrastructure and that "this is a technology delivering real answers to society's concerns about fuel consumption and greenhouse gas emissions without compromises."
