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.

Audi testing long-tail version of R18 e-tron quattro for Le Mans

Race teams are always looking for ways to shave hundredths of seconds of their lap times. Case in point: Audi is making some slight changes to its prototype racecar to make it ever so much more slippery as it cuts through the air.
Debuting at the second round of the FIA World Endurance Championship at Spa on May 4, Audi will be testing a long-tail version of its R18 E-tron Quattro racecar. As its name suggests, the long-tail car gets a lengthened rear section with the goal of improving aerodynamics. The long-tail will be run alongside the standard version of the racecar as a testbed for possible changes that might be in store, heading into the 24 Hours of Le Mans.
Audi did not say how many inches were added to the racecar, but as you can see in the image above, "long-tail" definitely doesn't take on the same meaning of classic long-tail cars of the past such as the Porsche 917. More information about the car, Audi's team and even some info about the track itself can be found below.

Mercedes-Benz, Volkswagen, and Audi announce Takata recalls

Daimler, Volkswagen, and Audi will recall nearly 1.7 million total vehicles in the US to replace their Takata airbag inflators. The Japanese parts supplier and the National Highway Traffic Safety Administration announced in late January that several automakers would need to fix around five million more vehicles, and the various companies have been releasing the details since then. Daimler has a recall for 841,000 vehicles in the US, including 705,000 from Mercedes-Benz and 136,000 from the company's van division. Reuters reports the affected models consist of 2005-2014 examples of the SLK-Class, C-Class, E-Class, M-Class, GL-Class, R-Class, and SLS-Class. The vans comprise the 2007-2014 models of the Dodge, Freightliner, and Mercedes Sprinter. Autoblog reached out to Mercedes USA to confirm these details, and we're awaiting a reply. Daimler expects the repair campaign to cost 340 million euros ($382 million at current rates). The company will book the costs as part of its financial year 2015 results, and net profit for that year will fall to 8.7 billion euros ($9.8 billion). Volkswagen's recall covers 680,000 vehicles in the US to replace their driver side airbags. The affected models have Takata's SDI and PSDI-5 inflators, which could rupture in an crash, but the automaker isn't aware of any explosions for these parts in its products. This campaign includes: 2006-2010 Passat Sedan and Wagon (German Production) 2012-2014 Eos 2010-2014 Golf 2010-2014 Jetta SportWagen 2012-2014 Passat (U.S. Production) 2009-2014 CC There are also 170,000 Audi vehicles with the SDI and PSDI-5 inflators in the US, but there are no reports of the parts rupturing in the company's models. The affected products are: 2005-2013 A3 2006-2009 A4 Cabrio 2009-2012 Q5 2010-2011 A5 Cabrio VW and Audi are still working to identify the specific VINs for these vehicles. Afterwards, they will notify affected owners. Ford, Mazda, and Honda already announced details for their new round of Takata repairs. VW and Audi also recalled a small number of Tiguans and Q5s to replace their side airbag inflators from the Japanese company. NHTSA still expects BMW and Saab to detail expanded safety campaigns.
