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.

Watch Stanford's self-driving Audi hit the track

Sending a self-driving race car around a track with nobody inside seems pointless – there's no driver to enjoy the ride, and the car certainly isn't getting a thrill out of it. But the students performing research with Stanford University's Audi TTS test rig "Shelley" (not to be confused with Audi's own self-driving race cars) are getting a kick out of the numbers generated by the machine. "A race car driver can use all of a car's functionality to drive fast," says Stanford Professor Chris Gerdes. "We want to access that same functionality to make driving safer." The teams push the car to speeds over 120mph and the computers have executed lap times nearly as fast as professional drivers. However, they also spend a lot of time maneuvering at 50 to 75 mph, the speeds where accidents are most likely to happen. That way, the students can figure out how to incorporate braking, throttle and maneuvering to develop new types of automatic collision avoidance algorithms. Better technology, for instance, could have saved Google from a recent slow-speed accident where its vehicle was struck by a bus. During race days, students break into teams to perform different types of research. "Once you get to the track, things can go differently than you expect. So it's an excellent lesson of advanced planning," says Gerdes. In the latest rounds of testing, for instance, one PhD student developed emergency lane-change algorithms, while another recorded a skilled human driver in an attempt to convert his behavior into a driving algorithm. The main goal, of course, is to prepare students for something they may not have expected -- an automotive industry that is adopting self-driving technology at breakneck speeds.

Audi CEO's Dieselgate arrest threatens fragile truce among VW stakeholders

FRANKFURT — The arrest and detention of Audi's chief executive forces Volkswagen Group's competing stakeholders to renegotiate the delicate balance of power that has helped keep Audi CEO Rupert Stadler in office. Volkswagen's directors are discussing how to run Audi, its most profitable division, following the arrest of the brand's long-time boss on Monday as part of Germany's investigations into the carmaker's emissions cheating scandal. The supervisory board of Audi, meanwhile, has suspended Stadler and appointed Dutchman Bram Schot as an interim replacement, a source familiar with the matter said on Tuesday. Schot joined the Volkswagen Group in 2011 after having worked as president and CEO of Mercedes-Benz Italia. He has been Audi's board member for sales and marketing since last September. The discussions risk reigniting tensions among VW's controlling Piech and Porsche families, its powerful labor representatives and its home region of Lower Saxony. VW has insisted the development of illegal software, also known as "defeat devices," installed in millions of cars was the work of low-level employees, and that no management board members were involved. U.S. prosecutors have challenged this by indicting VW's former chief executive Martin Winterkorn. Stadler's arrest raises further questions. Audi and VW said on Monday that Stadler was presumed innocent unless proved otherwise. Munich prosecutors detained Stadler to prevent him from obstructing a probe into Audi's emissions cheating, they said on Monday. Stadler is being investigated for suspected fraud and false advertising. Here are the main factors deciding the fate of Audi. Background: Audi's role in Dieselgate Volkswagen Group was plunged into crisis in 2015 after U.S. regulators found Europe's biggest carmaker had equipped cars with software to cheat emissions tests on diesel engines. The technique of using software to detect a pollution test procedure, and to increase the effectiveness of emissions filters to mask pollution levels only during tests, was first developed at Audi. "In designing the defeat device, VW engineers borrowed the original concept of the dual-mode, emissions cycle-beating software from Audi," VW said in its plea agreement with U.S. authorities in January 2017, in which the company agreed to pay a $4.3 billion fine to reach a settlement with U.S. regulators.
