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 turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

Audi Q7 E-Tron confirmed?

Rumors out of Australia say we'll be seeing a new variant of the Audi Q7 when the next-generation models bows in a few years. Joining the diesel and gas range will be the second production member of Audi's E-Tron family, which was introduced by the R8 E-Tron, but will actually see production in the form of the A3 E-Tron.
Speaking with Audi's managing director in Australia, Andrew Doyle, Car Advice asked what the future held now that the electrified R8 had effectively been shelved. "I don't see it [R8 E-Tron] as a major thing for us. We'll launch [locally] with A3, followed by Q7..."
The new Q7 will share its platform with the Volkswagen Group's two other large SUVs, the Porsche Cayenne and Volkswagen Touareg. But, as Car Advice is quick to point out, the Porsche and VW variants are slated for arrive next year - the second-generation Q7 won't arrive until 2015. Doyle refused to explain the discrepancy.
