VW fix would have cost $335 per vehicle

Since the Volkswagen diesel kerfuffle began, Bosch, the world's largest auto supplier, has been hooked up to a bullhorn trying to make sure everyone knows its side of the story. Bosch supplied VW with the engine management testing software, including delivery and metering modules, that VW then used to skirt emissions laws in the US. Bosch told VW in 2007 that it was illegal to use the software in cars it planned to sell yet VW did it anyway, according to reports coming out in German newspapers Bild am Sonntag and Frankfurter Allgemeine Zeitung. That first warning came two years after VW started developing the small-displacement diesel, around the time that the two men pushing its development, then-brand chief Wolfgang Bernhard and engineer Rudolf Krebs, were telling their superiors that the engine needed AdBlue urea injection to pass US emissions. VW cost controllers wouldn't approve the AdBlue solution because it would add 300 euros ($335 US) to the cost of the vehicle. Bernhard and Krebs left the same year that Bosch advised VW about the software, two years before the engine went into production. That's when things get cloudy. A report in Automotive News says that when Martin Winterkorn took over in 2007 as head of the VW Group and brand, he asked Ulrich Hackenberg and Wolfgang Hatz to keep working on the engine, and "[the] engine then ended up in VW Group diesels" with that problematic software still intact. No one has yet pointed any fingers at this latter chain of command, but like a game of Clue, right now they're the professors in the library holding the candlesticks. Warnings didn't only come from the supplier: Frankfurter says VW's initial investigation has found that an engineer issued the same caution to the company in 2011. Neither Bosch nor VW would comment on the reports.

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 could come to US with TDI power

When Audi released the new SQ7 TDI, we couldn't help but wonder whether it would ever see an American road or showroom. And the answer is: maybe. When reached for comment on the prospect of the new diesel performance ute making its way to North America, Audi USA spokesman Mark Dahncke told Autoblog that "the SQ7 is not officially signed off on for the US, but we are optimistic." Those are encouraging words, even if they stop short of official confirmation. For those who missed the announcement in the wake of the Geneva Motor Show last week, the new Audi SQ7 TDI is a technological tour de force. It packs a 4.0-liter V8 diesel engine, augmented by two turbochargers and an electric compressor to produce 435 horsepower and 664 pound-feet of torque. It debuts a new 48-volt electrical system that powers one of the compressor and the electromechanical adaptive suspension. And just for good measure, it also features an eight-speed automatic transmission, a four-wheel steering system and all-wheel drive. The vehicle represents the first time Ingolstadt has applied the S performance badge to its largest model, and though initially announced for Europe, Dahncke's optimism leaves us hopeful in turn that it could steam its own way to American shores. If that optimism proves justified, the next big question is whether it will stick with the diesel engine or switch to a similarly powerful engine burning gasoline to more closely match American preferences – much as it did in bringing the smaller SQ5 to the US. But Dahncke tells us they "expect it to be a TDI if it does come." The decision to market a powerful diesel SUV in America would be a bold move on Audi's behalf, particularly in the wake of the diesel emissions scandal. The debacle is still fresh on the public's mind, having rocked the entire Volkswagen Group of which Audi is part – and historically a major proponent of diesel propulsion. If approved for the US market as proposed, the SQ7 TDI would far outshine the diesel versions of the Mercedes GL-Class, Porsche Cayenne, BMW X5, and Range Rover currently available – not to mention the 3.0-liter V6 TDI with 240 hp and 428 lb-ft of torque in many of Audi's models (which are, at the time of this writing, affected by a stop-sale in the US).
