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-gen Audi R8 E-Tron could have 280-mile range

Will the next hypermiling contest take place between the latest iteration of the Audi R8 E-Tron and a Tesla Model S. On paper, the single-charge range between the high- and higher-end EVs are nearly identical, so it's possible. But what fun would that be, using light pedal foot and all? Audi has released the latest specs for the R8 E-Tron, and they are just beastly. The EV will deliver 456 horsepower, have 679 pound-feet of torque and will be able to jet from 0 to 60 miles per hour in less than four seconds. More stunningly, the car will have a single-charge range of 280 miles, which is about 15 miles longer than the Model S's range. Audi says the new, long-distance pack is due to " new battery cells," but declined to go into detail. Despite the excellent numbers, not everyone thinks a new R8 E-Tron poses any threat to Tesla. Prices for the "base" version of the R8 with a gas-powered V10 engine start at 165,000 euros ($185,000), and there's no guessing yet what an EV version will cost. Whatever it is, the car's been markedly improved compared to the earlier iterations. We reported on progress of the new R8 E-Tron about a year ago that the single-charge range would climb to about 250 miles, and that the mill would deliver about 376 horsepower. Audi first showed off a concept version of the car at 2009's Frankfurt Auto Show, saying at the time that the model had a single-charge range of about 150 miles. So this is good progress. Check out Audi's rather lengthy press release below. Audi presents the new R8: The sporty spearhead just got even sharper The second generation of the high-performance sports car makes its debut in Geneva 5.2 FSI engine with up to 449 kW (610 hp), 0 to 100 km/h (62.1 mph) in 3.2 seconds New multimaterial Audi Space Frame with high proportions of aluminum and CFRP No model with the four rings is closer to motorsport, none is more striking and more dynamic: at the Geneva Motor Show, Audi is presenting the second generation of its high-performance R8 sports car. The V10 mid-engine and a newly developed quattro drive ensure breathtaking driving performance, especially in the top-of-the-range version with 449 kW (610 hp): achieving 0 to 100 km/h (62.1 mph) in just 3.2 seconds, its top speed is 330 km/h (205.1 mph).

CO2-neutral* Audi A3 G-Tron goes on sale in Germany

The Audi A3 Sportback G-Tron has been on our natural gas-powered radar since it was unveiled at last year's Geneva Motor Show. Just before the big show starts up again this year, Audi put the new G-Tron vehicle on sale in Germany today, starting at 25,900 euros ($35,400 US). Anyone who opts for the Audi e-gas fuel card will be able to cruise the Autobahn knowing that their emissions will be CO2-neutral. That's because Audi has built an e-gas plant in Werlte in Lower Saxony, Germany that creates a synthetic methane that is compatible with natural gas from a process that uses "green electricity" to "[bind] as much CO2 as is released when the Audi A3 g-tron is driven in gas mode." Your own A3 G-Tron doesn't burn the carbon-neutral fuel directly, but the automaker will track how much is spent using the fuel card and make sure "that exactly this amount of Audi e-gas is fed into the German natural gas network." Audi charges 14.95 euros a month to use the card. Burning that e-gas in the A3's 1.4-liter TFSI engine can put out 110 horsepower (you can also burn regular natural gas or gasoline) and offers fuel economy of between 3.2 and 3.3 kilograms of gas per 100 kilometers on natural gas Audi A3 g-tron: Advance sales get the green light Ingolstadt, 2014-02-13 Audi A3 Sportback g-tron available to order from February 13 CO2-neutral mobility with the Audi e-gas fuel card Prof. Dr. Ulrich Hackenberg: "Audi e-gas is an important pillar of our sustainability strategy" The Audi A3 g-tron is all set to hit the roads. Advance sales at dealerships in Germany will kick off on February 13. The basic price will be 25,900 euros. Using the Audi e-gas fuel card, customers can opt for Audi e-gas to power their A3 g-tron without impacting the environment if they wish. The Audi A3 g-tron forms part of a new, integrated and sustainable mobility concept from the brand with the four rings. Its 1.4-liter TFSI engine developing 81 kW (110 hp) can be operated using either natural gas, e-gas generated by Audi or gasoline. In pure e-gas mode the g-tron is entirely CO2-neutral. Audi e-gas is a synthetic methane that is produced at the Audi e-gas facility located in Werlte in Lower Saxony, Germany – the world's first industrial power-to-gas plant. An A3 Sportback g-tron fueled by Audi e-gas is currently the most environmentally friendly form of long-distance mobility.
