Volkswagen Group previews its wares on eve of Geneva show

The Volkswagen Group is comprised of 11 brands producing 240 vehicles across 49 factories throughout the world. So the best way to show off the range of the VW family is to cram a few thousand journalists and VIPs into a massive makeshift stand to outline the Group's goals, what's in the pipeline and what you'll be able to buy later this year.
To that end, VW pulled out all the stops on the eve of the 2012 Geneva Motor Show, bringing along 10 vehicles from across the range. We'll be delving into the details of each over the next two days of show coverage, but before that happens, you can read all about what we saw tonight from the cheap seats after the break.

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.

Next Audi RS4 to get V6 turbo, US sales still unclear

Audi's high-performance S models have forged a reputation in the US for offering wonderful driving dynamics in a package that doesn't scream, "I bought a sport sedan." However, its even higher-performance RS models are still somewhat of a rarity here. While the RS5 and RS7 are in the current US lineup, many of the wild RS models that Europe gets, like the RS6 Avant (pictured above), never make it to these shores. Unfortunately, that might not be changing anytime soon with the next-gen RS4.
The RS4 will follow the lead of the next BMW M3/M4 and (rumored) next Mercedes-Benz C-Class AMG and make the switch to a smaller turbocharged powerplant. According to an Audi insider speaking to Car and Driver, the next RS4 will drop the last generation's 4.2-liter V8 in favor of a turbocharged V6. The engine block will likely be shared with the supercharged 3.0-liter V6 in the regular S4 but fitted with two turbochargers. Power would likely be around 400 horsepower to match the 425-hp M3 and rumored 450-hp C-Class AMG.
Unfortunately, the RS might not make it across the pond to our waiting hands because the source says no decision has been made to export them yet. Obviously, we hope that Audi makes the right decision and brings the next RS4 here.
