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 TT Offroad concept packs 408 hybrid horsepower, yet returns 123 mpg

Audi took the wraps of its TT Offroad Concept at the Beijing Motor Show, after teasing us with sketches earlier this month. "The Audi TT offroad concept provides a glimpse of how we might imagine a new model in the future TT family," says Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development. "It combines the sporty genes of the TT with the strengths of a compact Audi SUV."
The latest in Audi's eTron show cars reminds us an awful lot of the the Audi Allroad Shooting Brake concept that debuted a few months ago at the Detroit Auto Show. In addition to very similar physical appearances, the two share the same plug-in hybrid propulsion systems (the "plug-in" part is a bit misleading, as the concept simply needs to be parked over an inductive pad to take advantage of Audi Wireless Charging technology).
Proving that hybrid power never has to be a compromise, the TT Offroad Concept packs a 292 horsepower turbocharged 2.0-liter four-cylinder under the hood. The combustion engine is assisted by two electric motors (rated at 40 kW at the front and 85 kW at the rear) to provide a total system output of 408 horsepower and nearly 480 pound-feet of torque. With all-wheel drive, the concept hits 60 mph in 5.2 seconds and tops out at 155 mph - while returning a provisional fuel efficiency of 123 miles per gallon equivalent.

Audi Q1 captured wearing production metal for first time

Audi is getting closer and closer to introducing its smallest crossover ever in the form of the new Q1. Now, we have our very first shots of the mini cute ute wearing its production skin. Expected to make its debut in 2016, it would seem that the Q1 will follow the trend set by the Q3 and draw inspiration from the brand's Q5 mid-sizer. Proportionally, it doesn't look dramatically smaller than the Q3. The front overhang is similarly sized, although there's a smaller rear overhang and a more aggressive rake to the rear window. The front windshield looks more aggressive too, and overall, the Q1 looks to sit lower to the ground than its big brother. While it shares a number of parts with the current Audi A1, when the Q1 debuts, it won't be based on the same platform. Audi's smallest car rides on the Volkswagen Polo's platform, while our spies report that the Q1 will instead be based on the Volkswagen Group's MQB platform. Despite the different platforms, though, expect there to be some sharing of powerplants. That means a variety of gas engines, and likely a version of the A1's 1.6-liter, turbodiesel four-cylinder. There should also be an SQ1 coming shortly after the standard model debuts. You know, for all the folks demanding a high-performance, all-wheel-drive, luxury mini crossover.
