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 trademarks SQ2, SQ4, Q9 and F-Tron nameplates

Audi is planning a whole raft of new models for the near future, and now we have further insight into what at least some of those models might be. The German automaker has reportedly filed trademarks for a series of model names, including SQ2, SQ4, Q9 and F-Tron.
Following in the footsteps of the SQ5 performance crossover, the SQ2 and SQ4 nameplates would seem to indicate that Audi is planning performance versions of its upcoming compact crossovers. The Q9 would suggest that a larger crossover is in the works to slot in above the already gargantuan Q7. And the F-Tron name could be used for a fuel-cell version of the A7 or other models, following a similar naming pattern to the e-tron range of electric vehicles.
Of course Audi could simply be filing these trademarks as a safeguard and may not actually build any of these models. But one way or another, it indicates a certain measure of intent exists as Ingolstadt gears up to expand its lineup with 11 new models in the next few years.

Audi planning S3 Plus with 375 hp?

There's a war being waged in Europe for the highest output from the smallest displacement. Alfa Romeo has managed to squeeze 240 horsepower and 260 pound-feet of torque out of a 1.7-liter turbo four for the 4C. Mercedes-Benz has coaxed 355 hp and 332 lb-ft out of a 2.0-liter turbo four to drive the new A45 AMG, CLA45 AMG and GLA45 AMG. But not to be outdone, the Volkswagen Group is said to be working on one of its own that will put both to shame.
The engine is reportedly being based on VW's existing 2.0-liter turbo four, only enhanced to produce a massive 375 hp and 369 lb-ft of torque. The key to getting there was poaching Friedrich Eichler, the engineer who designed AMG's aforementioned high-output engine, and mandating him to do still better.
That's all well and fine - and perfectly impressive - but just what does VW plan on doing with the new engine? A whole lot, according to reports. It's expected to power the new Scirocco and a new Golf R Evo expected to debut at the Beijing Motor Show in April, and you can bet it'll be slotted into another few applications as well. But the first vehicle expected to get it will be the Audi S3 Plus.
