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.

Audi SQ7 coming, will have electric turbo

Formula 1 and endurance racing are already harvesting energy from turbos on the track, and now it's apparently time for a similar idea of boosting the efficiency of forced induction to hit the streets in a high-performance, diesel SUV.
In a recent interview with the UK's Autocar, Audi technical boss Dr. Ulrich Hackenberg let the big news slip. "The new Q7 will be available in the market next year but the electric turbo will come a bit later in the Audi SQ7 available in 2016," he said. The e-turbo system was already rumored for the premium SUV but for the standard model, not this just-announced performance version.
Audi has been experimenting with the e-turbo system for a little while, as an electrically driven supercharger. It showed up on the RS5 TDI concept that used a 3.0-liter, twin-turbocharged diesel V6 plus the electric system to diminish turbo lag. In that application, it provided an impressive 385 horsepower and 553 pound-feet of torque and an alleged sprint to 62 miles per hour in 4 seconds. Although, Dr. Hackenberg didn't make it clear if this was the exact layout for the SQ7.

More next-gen Audi TT details revealed

We still only have rumors about the third-generation Audi TT said to be scheduled for launch in late 2014, but based on a report in Car and Driver, we know a tiny bit more about it. The base engine will be the 2.0-liter turbo four-cylinder with direct injection, but horsepower is said to be 220 horsepower - that would make for a nine-hp jump over the current output. The TTS would get an even larger power boost, going from 265 currently to 300 hp. The TT RS would stick with it's 2.5-liter five cylinder, with output increased from 360 to 380 hp. If Audi includes a nice dose of the go-light engineering involved in the TT Ultra Quattro, these horsepower numbers might be even more impressive.
As with the TT concept and first-generation production car, though, it sounds like the brand is concentrating on aesthetics. It's been widely reported that Audi wants to reclaim the juju conjured by the original TT, and while we still don't know what that means outside, CD reports that the interior gets simplified, "futuristic-feeling" styling thanks to instruments served up on a TFT screen. Remember, the first Audi TT had a cockpit that Car magazine dubbed simply, "The Cabin."
About a year after the coupe comes, the Audi TT Roadster will show up and should be joined by the next A5. The news for the next version of the subtly beautiful coupe is the arrival of a plug-in hybrid with torque vectoring via an electric motor for the rear axle. Beyond that is wilder speculation of an A9, which might be called Q9, and which was the four-door-coupe flavor of the month two years ago when it was possibly going to share a platform with the Lamborghini Estoque. According to the CD story, the thinking now is around "a combination of fastback and crossover proportions," a two-fer we've yet to see any carmaker pull off without making us go, "Oh. I see."
