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.

VW recalling 2.64M vehicles worldwide over engine, light issues

Volkswagen is staging a massive, worldwide recall that's already grown from 1.68 million to 2.64 million vehicles and covers three different issues across a number of vehicles. We already reported on 61,000 Tiguans getting recalled over lighting issues - that was just in the US. Globally, however, VW will be recalling 800,000 Tiguans, according to Automotive News, with the focus on CUVs built between 2008 and 2011. The issue with the Tiguan relates to a simple fuse swap, so this is rather unremarkable, aside from the sheer number of vehicles being fixed. The real, troubling issues relate to gearboxes and pickups.
239,000 Amarok pickups (pictured right) are being recalled over fuel leaks, while 1.6 million vehicles are being recalled to swap the synthetic oil in dual-clutch transmissions with mineral oil. Now, the transmission issue is one for the global Volkswagen Group to address, not just the VW brand - vehicles from Audi, Škoda and Seat use the same seven-speed DSG and are covered under the recall, as well.
Why the switch from synthetic to mineral oil? Apparently, using the synthetic oil in a DSG and then subjecting it to stop-and-go conditions or heavy loads in a hot and humid climate can lead to electronic malfunctions, according to a Volkswagen press release. The switch, from the sounds of it, is largely a preventative measure.

Audi RS4 Avant Nogaro Selection puts a fresh face on old memories

I've been fortunate enough to drive plenty of memorable cars over the years, and one of my all-time favorites is the Audi RS4 sedan. It was only sold in the United States for a short time, but during that quick run, it made a huge impression on me. I remember everything about that car - the smell, the sound, the exact feeling of the manual shifter as it clicked between the six gears, and the texture of the steering wheel that I so happily tossed about. In fact, whenever I'm feeling nostalgic, I go back and watch this video of the late David E. Davis, Jr., running the California Mille roads in a Sprint Blue RS4 - a video we shot for Winding Road many years ago during my tenure as an editor there.
So even though the Audi RS4 Avant Nogaro that debuts here in Geneva isn't super important, especially for our American-centric audience, I feel compelled to write about it. No, we don't get the lovely RS4 in the States anymore, but the package offered in Europe is just as sweet as ever - perhaps even more so, what with that stylish longroof shape. Under the hood is Audi's excellent, naturally aspirated 4.2-liter V8 engine, tuned to deliver 450 horsepower and 317 pound-feet of torque, allowing for a 0-62 sprint of 4.7 seconds.
The Nogaro name refers to the special blue paint - a throwback to the original Audi RS2 Avant that kicked off the company's super sweet luxury offerings. Other unique features for the Nogaro car include gloss black exhaust outlets, window frames and grille surround, as well as matte black roof rails. Special 20-inch wheels round off the exterior enhancements, and inside, Nogaro Blue Alcantara accents can be had on the door panels and seat inners.
