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:

Audi creates new diesel fuel from carbon dioxide and water

What if you could power cars of the future with pollution created by the cars of the past? That's what German automaker Audi is hoping to achieve by creating a new synthetic fuel using renewable energy to turn water and carbon dioxide gas into a new kind of fuel they call "e-diesel." The new diesel is being produced at Audi's pilot plant Sunfire in Dresden, Germany. Only a few gallons were created, which the German Federal Minister of Education and Research Johanna Wanka put into her Audi A8 to prove the fuel's bonafides. The base fuel is known as "blue crude" and begins from a green source. Audi uses electricity from wind, water or solar power sources to separate hydrogen from oxygen in water. The hydrogen is then mixed with carbon dioxide which has been converted in carbon oxide. The blue crude is then further refined to create the e-diesel. The carbon dioxide is currently supplied by a biogas facilities, but some of that CO2 was captured from the air. "The engine runs quieter and fewer pollutants are being created," says Sunfire CTO Christian von Olshausen. The fuel can be combined with conventional diesel fuel, as biodiesel fuels already and would be competitively priced against regular diesel, according to Gizmag. Sunfire can produce about 42 gallons of e-diesel a day. That seems like barely a drop in the bucket in terms of Europe's energy use, but Audi is ready to commercialize the technology with plans to expand production with a bigger facility in the future.

Electric 1960 Auto Union 1000S has vintage looks, modern power

If you want to buy a classic car but somehow feel a twinge of guilt about the old engine polluting too much, then it's worth taking a look at this 1960 Auto Union 1000S on eBay Motors. The owner removed the original three-cylinder, two-stroke and installed a fully electric powertrain. In place of the internal combustion engine, there's an Azure Dynamics three-phase AC24 motor to spin the front wheels, and it even has regenerative braking. Lithium-ion batteries replace the rear seat and extend into the trunk to supply 21.5 kWh of energy storage. The seller claims the Auto Union weighs 2,400 pounds, so the powertrain might be rather lively in such a light car. From the outside, this Auto Union is immaculate. The owner's body-off restoration includes powder coating the chassis and suspension and repainting the exterior in Ascot Grey with the white roof. The color scheme looks perfect on cars of this era. The interior now has a digital instrument cluster in the center of the dash. We could see this change upsetting some purists because of the clash between original and modern. However, the reupholstered fabric seats look amazing. The owner has covered 15,000 miles since the restoration, so any powertrain bugs have been worked out in that time. As of this writing, the bidding is at $15,100 with 28 bids and the reserve is not yet met. The auction ends Sunday, April 10. While the seller provides great photos with the sale, you can see the EV in motion below in a video Audi created about it in 2014.
