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 supercar not yet approved, R4 not quite dead, still room for an MPV

According to a report by Autocar, all we thought we knew of the in-development Audi supercar we might not actually know. A piece in Car and Driver, not even a month old, said the diesel-hybrid halo car was in the design stages, would get the engine from the R18 E-Tron Quattro and its carbon fiber tub. Now we get word that that while the coupe is indeed being designed, it hasn't yet been signed off and there's no business case for it yet. Said business case, whenever it is built, is also dubious of the diesel aspect of the car at the moment - diesels aren't known for creating Pavlovian purchase responses in buyers in the two key markets of the US and China.
The report suggests that instead of a diesel, the 2014 Le Mans regulations changes "could swing the favour back towards petrol models," which would give the so-called Scorpion a better tie to racing technology. Of course, that also assumes that Audi would contest next year's Le Mans with a gas-powered car. If so, that would be an about-face on the original reasons for the halo sportscar in the first place.
In other news, seems Audi also believes it can slot another sportscar below the R8, it just needs to get the financials sorted. The R4 - a Porsche Boxster-sized roadster - that has been chattered about for years is still in on the table but appears a long way off. Company R&D chief Wolfgang Durheimer said it would need to be mid-engined and bring plenty of tech to separate itself from the TT, but mass-market price point is the catch as is the focus on other segments in the portfolio.

KBB: VW diesel prices have dropped 16%

There are a lot of post-scandal theories and metrics concerning Volkswagen's performance during the diesel emissions scandal, although none of them has created a clear picture of where things are headed. Kelley Blue Book has a few more to add to the spreadsheet, though, finding that average auction prices for VW diesels and Internet shoppers perusing them have both gone down in the past four weeks on KBB.com. Auction prices on the site are down an average of 16 percent for VW oil burners, which compares to a decline of 2.9 percent for gas-powered VWs. Shoppers are still on the lookout, though, even if the numbers are slightly reduced. Overall, "new-car shopping activity" for the small-capacity VW diesel offerings is down 2.4 percent, a number held partly in check by searches for the Jetta SportWagen being up by 3.7 percent. Shoppers are looking harder at the Audi A3 diesel, too, its activity up 1.6 percent. The Golf, though, is down 3.7 percent and the Golf SportWagen down 6.2 percent. Shoppers leaving the diesel fold aren't necessarily going for high-mileage options, either, KBB saying that the Ford Fusion and Honda Civic are quick alternatives to the Jetta TDI, while the Mercedes CLA and BMW 2 Series are getting new looks from those interested in the Audi A3 diesel. You can read the full release from KBB below. VOLKSWAGEN DIESEL VEHICLE PRICES DECLINE NEARLY 16 PERCENT, ACCORDING TO KELLEY BLUE BOOK DATA New-Car Shopping Activity Also Impacted by Recent Emissions Issue IRVINE, Calif., October 21, 2015 – Kelley Blue Book www.kbb.com, the only vehicle valuation and information source trusted and relied upon by both consumers and the automotive industry, today reports that average auction prices, along with new-car shopping activity on KBB.com, for Volkswagen diesel vehicles have declined four weeks after the diesel emissions issue was announced. The average auction price for Volkswagen diesel models dropped by nearly 16 percent since the news broke of the emissions crisis.[1] The average auction price for the brand's gasoline-powered vehicles declined by 2.9 percent.1 On KBB.com, Volkswagen new-car shopping activity for affected TDI models has decreased on average by 2.4 percent. "According to Kelley Blue Book Field Analysts, some auctions are still holding off on selling the affected Volkswagen inventory," said Tim Fleming, analyst for Kelley Blue Book.
