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.

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.

VW confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models.
