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 Prologue Avant Concept points to the future of wagon design in Geneva [w/video]

The new generation Audi R8 and its LMS GT3 racing version are grabbing much of the attention at the Audi stand at the Geneva Motor Show. However, if you are more interested in seeing the brand's future design direction, just take a look at the Prologue Avant Concept that's also on display. Audi traditionally uses the Avant name for the company's wagons, but that's tweaked slightly here. The vehicle is certainly a five-door, but from some angles it looks more akin to a Porsche Panamera-like hatchback. Compared to the B-pillarless Prologue Coupe (that we recently drove), the stretched roof flows all the way to the angled rear hatch, and the result is a very elegant design. The interior tends towards minimalism with just a few screens showing the driving info. The Prologue Avant also ditches the Coupe's petrol-fueled hybrid for a 3.0-liter, twin-turbo diesel V6 plug-in hybrid with a total of 455 horsepower and 553 pound-feet of torque, which is linked to an eight-speed gearbox. Audi claims the setup reaches 62 miles per hour in 5.1 seconds and allows for 33 miles of pure electric driving. To get a sneak peek at what's next from Audi, take a look at the Prologue Avant Concept on the floor of the Geneva show in the gallery above.
