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.

Hyundai tops VW and Buick in China, survey says

You may be aware of the long-time competition in China between Volkswagen and Buick, but another brand apparently should be in that conversation too: Hyundai. In a recently published annual consumer survey, the Korean company actually took the top spot to beat out its German and American rivals in second and third, respectively. The results were part of the China Brand Power Index that interviewed 11,500 people around the nation and was paid for by the country's Ministry of Industry and Information Technology. While Hyundai proved popular with voters, its sales haven't necessarily shown that yet. According to Bloomberg, the brand had falling numbers in China for the first quarter of the year. Even Ford outsold the South Korean automaker in the same period, despite scoring lower on the survey. Meanwhile, Audi ranked as the populace's favorite luxury brand, which is hardly a surprise given the Four Rings' strong sales in China. In January alone the automaker saw a 15-percent boost in volume there. Parent company VW's strong performance was somewhat more surprising, though. State media severely criticized the German automaker in March, and customers protested last year for the allegedly poor handling of a recall.

Audi billboard tracks pedestrians like prison escapees

Audi's adaptive Matrix LED headlights can actively dim and direct light around the road to make driving safer at night. Unfortunately, the tech runs afoul of Department of Transportation rules, so it isn't currently available in the United States. For an idea of what you're missing, a marketing stunt for the new A4 in Belgium is illuminating the night and making pedestrians in the intersection more visible, and safer. The only problem is, it also makes them look like fugitives making an escape. From a giant billboard near the Brussels Central Station, the LEDs from a massive Audi A4 can light up whole intersection. Whenever a pedestrian or cyclist enters the area at night, they are tracked the whole way in a radiant pillar of blue luminescence. Based on this clip, the lights look bright enough to temporarily blind some passersby. Despite the unintended consequences, the stunt is still a very visible demonstration of Audi's headlight technology. Related Video: The video meant to be presented here is no longer available.
