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 A3 E-Tron plug-in hybrid set to whiz into Geneva

The Audi A3 E-tron, which we drove in prototype form last year, is headed to the 2013 Geneva Motor Show next month. The plug-in hybrid will feature a total of 204 horsepower and 258 pound-feet of torque from the combination of a turbocharged 1.4-liter engine and a 75-kW electric motor. That motor itself is positioned between the internal combustion engine and the machine's six-speed dual-clutch transmission. The setup is good enough to scoot the A3 E-tron to 62 miles per hour in 7.6 seconds and crank out a top speed of 138 mph. Perhaps more impressively, the hatch can whir its way to 80 mph on all-electric power with an EV range of 31 miles.
Audi claims the A3 E-tron gives the world a "realistic glimpse into the future of mobility," so it's a bit unclear if the model will see production. We're encouraged by the specificity of Audi's press release (which is full of stats) and the fact that they don't label this vehicle a concept. You can check out the full press release below and judge for yourself.

Audi A8 and S8 get another video tease

If there was any doubt before about which car(s) Audi recently teased in a video, now we know for sure. Audi has released another teaser video that confirms we'll at least be seeing the 2015 Audi S8 (and very likely the A8 as well) in the near future, but the big surprise is just how soon we'll see the new flagship sedan. We originally expected to see the sedan receive its official debut at the Frankfurt Motor Show, but now Audi says that the car will be presented about three weeks before the event on August 21.
How do we know this is the S8? Well, aside from it obviously being a large sedan, the true tell that this is its A8/S8 is the front license plate, which clearly shows "S8" on it - we've been doing this long enough to know that Audi's promotional license plates have the model designation in the plate number. As for other details, Audi's trick Matrix headlights shine through the thin veil in what should be the crown jewel of the sedan's new face. There's a little more than a week to go until the car is unveiled, but for now, check out the video below.
