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.

2014 Audi A6, A7 and Q5 TDI diesel models get pricing and fuel economy figures [w/videos]

Last year, Audi announced that it was expanding its lineup of TDI models for 2014 with the Q5, A6 and A7 joining the diesel-burning Q7 and A8 L models already in existence. The Q7 TDI has been out for a few years now and we recently drove the A8 L TDI, but now Audi has released the pricing, performance and fuel economy details for the 2014 Q5 TDI, A6 TDI and the ever-stylish A7 TDI. Down the road, Audi has also promised a TDI version of the next-generation A3 that will debut for 2014.
Until the new A3 TDI shows up, the Q5 will be the most affordable diesel model in Audi's lineup, with a starting price of $46,500 to go with fuel economy estimates of 24 mpg city and 31 mpg highway. The closely related A6 and A7 will get identical fuel economy numbers of 24 city and 38 highway in diesel form, with the A6 TDI starting at $57,500 and the A7 TDI starting at $66,900. In the three new TDI applications, Audi's 3.0-liter V6 produces 240 horsepower and 428 pound-feet of torque, and all models are paired with an eight-speed automatic transmission. Scroll down for videos (stock running footage) and more information on the Q5 TDI, A6 TDI and A7 TDI, all of which go on sale in late summer.
