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.

2015 Audi A3 Sedan priced from $29,900* [w/video]

One year after the all-new Audi A3 bowed in Europe, the US finally will get the 2015 A3 sedan in 2014, and the German automaker announced yesterday that it's priced from $29,900 (*not including destination, and we've reached out to Audi asking for the price of delivery). A bit later in 2014, the A3 Cabriolet will be released along with the S3 sedan. The A3 Sportback will be a 2015 model, though it will only be offered as a gasoline-electric hybrid. Prices weren't given for those models and, sadly, the three-door hatch isn't slated for US consumption.
The A3 sedan will be offered with three engine choices, all of them featuring direct-injection, turbocharging and four cylinders: a 1.8-liter TFSI, 2.0-liter TFSI and 2.0-liter TDI - that last one's a diesel. If you count the S3 sedan, that's another engine in the lineup - a 296-horsepower version of the 2.0 TFSI.
As we were told at the 2014 A3's "unofficial" world debut in New York City earlier this year, Audi says US customers won't get the option of a six-speed manual transmission, as the Europeans do. All engines will be mated exclusively to a six-speed dual-clutch transmission.

Audi Sport Quattro Concept speaks softly, carries a 700-hp stick

As promised, Audi has unveiled its Sport Quattro Concept here at the Frankfurt Motor Show, which takes inspiration from the 2010 Paris Motor Show debut known simply as the Quattro Concept. Both cars clearly seek to draw upon the company's legendary 1980 Ur-Quattro and its closely related Sport Quattro short-wheelbase rally special, yet this concept car looks more production-minded than the 2010 starlet.
Despite its more conservative duds, this handsome and muscular coupe actually packs significantly more power than the 2010 Paris showcar. In fact, it musters 700 horsepower and 590 pound-feet of torque from its plug-in hybrid powertrain, versus the Quattro Concept's more historically appropriate 2.5-liter five-cylinder turbo with 408 hp and 354 lb-ft. We're not going to complain about a twin-turbo 4.0-liter V8 plus an electric motor, nor will we grouse about its 3.7-second 0-62 mph dash, 190-mph top speed or 2.5 liters of fuel per 100 kilometers on the Euro cycle (roughly 94 miles per gallon US).
Stubborn rumors abound that Audi will offer a limited-edition version of this four-place coupe for sale, but for now, the company isn't talking. If such a model is offered, it's expected to cost significantly more than the R8 supercar, which might be a tough sell considering that vehicle's similar performance and more voluptuous - if less practical - shape.
