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 sets diesel records on road and track

Ever the proponent of diesel propulsion, Audi has claimed two very different kinds of records in Europe with its finest oil-burners. The more exciting of the two was achieved recently at the Sachsenring, where the Audi RS5 TDI Competition Concept posted the fastest diesel-powered lap time ever recorded on the track. As you may recall, Audi revealed the RS5 TDI Concept last year, swapping the gasoline-burning 4.2-liter V8 in the production RS5 coupe for a 3.0-liter V6 diesel with two turbochargers and an electric supercharger. The result was 385 horsepower and 553 pound-feet of torque, but Audi's been working on the prototype over the course of the past year. In the new Competition version, output is up to 435 hp and 590 lb-ft, and despite the inherently heavier diesel engine, it actually weighs 531 pounds less than the production model. That helped the RS5 TDI Competition lap the circuit in 1:35.35, besting the previous diesel lap record by 1.87 seconds, and adding to the Hockenheim record it took previously. Around the same time, another team set out from Maastricht in the Netherlands in an Audi A6 TDI Ultra and drove it for 28 hours straight, hitting 14 countries and logging 1,158.9 miles on a single tank of diesel. The achievement, certified by Guinness World Records, was completed in a showroom-stock vehicle, with automotive journalist Andrew Frankel and racing driver Rebecca Jackson splitting driving duties. They achieved an average of 75.9 miles per gallon – much better than the advertised rating of 67 mpg – as they cruised through from Holland to Hungary, passing along the way through Belgium, Luxembourg, France, Switzerland, Lichtenstein, Austria, Germany, Italy, Slovenia, Croatia, Bosnia, and Serbia. Record: Audi RS 5 TDI competition concept drives to record time on the Sachsenring track - Audi sets new lap record for cars with diesel engines - Superior technology platform with 435 hp and 800 Nm (590.0 lb-ft) - Electric compressor: overcomes turbo lag, enhances sprint performance Audi has set a new record time on the Sachsenring for cars with a diesel engine. The Audi RS 5 TDI competition concept rounded the 3.6 km (2.2 mi) race course in a time of 1 minute 35.35 seconds. The technology platform draws its power from a 3.0-liter V6 biturbo TDI with 320 kW (435 hp) of power and 800 Nm (590.0 lb-ft) of torque. The highlight is an electrically driven compressor.

Audi teases even more of the next TT ahead of Geneva in latest video

Audi is just a few days away from launching the third-generation TT at the 2014 Geneva Motor Show, but the new sports coupe has been so thoroughly teased, sketched, and spied that it almost seems like an anti-climax. Even the interior was thoroughly hinted at during this year's CES. But that's not keeping Audi from slowly revealing more and more parts of its new baby.
The TT is a modern automotive design icon. The first generation looked like nothing else on the road when it debuted, and the second generation added a needed dose of sportiness with the TTS and TT RS. The latest teaser video for Ingolstadt's sporty coupe shows more of its aluminum body than we've ever seen before, but the biggest mystery still lingering about the new TT is what engine Audi is slipping under the hood. Thankfully, the wait to find out will be quite short. Scroll down to get the best glimpse yet of the new coupe.
