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.

Next Audi A8 to drive itself up to 37 mph

Audi has been publicly, loudly, working the autonomous angle for years - it was working on Shelley, the autonomous TTS that would climb Pikes Peak in 27 minutes, way back in in 2009. Parent company Volkswagen had been working with Stanford University on autonomous vehicles for five years before that, and the same program collaboration would take the lead in Audi's efforts here. Where are we now? Well, a convoy of Audi A7s just drove journalists from San Francisco to the Consumer Electronics Show in Las Vegas, with "piloted driving in 100 mile stints." On the highway, the "piloted driving" A7 works up to 70 miles per hour and can change lanes, pass other cars, accelerate and brake on its own. A report in Autoweek says public adoption of the technology will continue with the next-generation A8, which will be able to navigate on its own up to 37 mph, make its way through traffic, find a parking spot and park itself. Over time, capabilities will be added - like a higher mph limit - as the technology and the legal issues are fine tuned. The A7 that just did the SF-to-LV run doesn't work in cities, only on highways, so it appears Audi is kicking this off with the abilities demonstrated in an A6 Avant last year at CES. That car had a Traffic Jam mode that only worked in dense traffic and up to 40 mph, but when in operation, it allowed the driver to watch a movie or conduct a videoconference. We have a feeling those two bits of icing won't be included in the fourth-generation A8, though. We'll be late to the party when the big sedan comes; Audi says it will go on sale by the end of 2016, but the US isn't expected to get it until 2017 as a 2018 model.

Is the Audi R8 E-Tron project back on again?

If you ask Audi about its R8 E-Tron prototype, the all-electric two-seater that was first shown at the 2009 Frankfurt Motor Show, the automaker will tell you that its development program is on hold. Yet, as we reported in January, limited production of the combustion-free coupe may be moving forward... information still officially unconfirmed by the automaker.
New images of the electrified R8 undergoing winter testing in Europe have emerged (above and in our gallery), and the car has been spotted running in Spain as well. Both sightings support reports that the E-Tron, with its 150-mile battery range and 8:09 Nürburgring time, may be back in business. Does the program have a green light, or is Audi merely trying to take some of the thunder from the BMW i8?
Whatever the case, if the R8 E-Tron does eventually make it into showrooms - and we are now led to believe it will - expect production volume to be very low. Assuming it doesn't get shelved again, of course.
