Winterkorn kept diesel scandal secret, letter claims

Former Volkswagen Group CEO Martin Winterkorn allegedly kept quiet for two weeks about emissions defeat devices in the company's models. US officials eventually made the automaker's deception public on September 18th. "In the conversation on 03.09.2015 with the regulator CARB (California Air Resources Board), the defeat device was admitted," an employee told Winterkorn on September 4, according to Reuters citing Germany's Bild am Sonntag. Based on this information, Winterkorn had plenty of time to admit the problem. Evidence like this letter continues to suggest top figures knew about the emissions problem. In addition, a separate Bild am Sonntag report recently claimed that an employee emailed Winterkorn in May 2014 to tell him US regulators could discover the cheating. In the lower echelons of the company, the deception was allegedly an open secret among engineers as early as 2006, and people kept quiet even after workers tried to admit what was happening. This culture of secrecy seems to go even deeper than just the diesel emissions scandal. For example, engineers admitted that they cheated on CO2 tests to meet the company's strict standards. According to Green Car Reports, these problems also affected the US. In 2004, an Audi worker in America allegedly discovered an issue with the exhaust gas temperature sensor in some vehicles, but a German executive said not to admit the problem to US regulators. It's not clear whether any high level employees tried to fix the diesel emissions issue or if they simply kept the problem hidden. The company's internal report, which is due in the latter half of April, might address that concern. So far, the VW Group has said only a small group of people caused the scandal. However, these many allegations to the contrary make that claim difficult to believe. Related Video:

Next Audi A8 to drive itself up to 37 mph

Audi has been publicly, loudly, working the autonomous angle for years - it was working on Shelley, the autonomous TTS that would climb Pikes Peak in 27 minutes, way back in in 2009. Parent company Volkswagen had been working with Stanford University on autonomous vehicles for five years before that, and the same program collaboration would take the lead in Audi's efforts here. Where are we now? Well, a convoy of Audi A7s just drove journalists from San Francisco to the Consumer Electronics Show in Las Vegas, with "piloted driving in 100 mile stints." On the highway, the "piloted driving" A7 works up to 70 miles per hour and can change lanes, pass other cars, accelerate and brake on its own. A report in Autoweek says public adoption of the technology will continue with the next-generation A8, which will be able to navigate on its own up to 37 mph, make its way through traffic, find a parking spot and park itself. Over time, capabilities will be added - like a higher mph limit - as the technology and the legal issues are fine tuned. The A7 that just did the SF-to-LV run doesn't work in cities, only on highways, so it appears Audi is kicking this off with the abilities demonstrated in an A6 Avant last year at CES. That car had a Traffic Jam mode that only worked in dense traffic and up to 40 mph, but when in operation, it allowed the driver to watch a movie or conduct a videoconference. We have a feeling those two bits of icing won't be included in the fourth-generation A8, though. We'll be late to the party when the big sedan comes; Audi says it will go on sale by the end of 2016, but the US isn't expected to get it until 2017 as a 2018 model.

New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:
