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 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.

2013 Audi RS6 Avant hauls ass and then some

Holy moly. Despite the fact that Audi first released details on its 2013 RS6 Avant back in December, we're still just as smitten with it now as we were a couple months ago. And why wouldn't we be? This stunning piece of forbidden fruit combines two of our favorite things: fast Audis and useful wagons.
The meat and potatoes behind the RS6 Avant is its twin-turbocharged 4.0-liter V8, tuned to crank out 560 horsepower and 516 pound-feet of torque. Mated to an eight-speed automatic transmission, the all-wheel-drive wagon can scoot to 60 miles per hour in just 3.9 seconds, on its way to a top speed of 155 mph. Opting for the Dynamic package ups that v-max to 174 mph, and selecting the Dynamic Plus pack increases that even further to 190 mph.
This RS6 Avant certainly looks the part of an extreme ass-hauler, fitted with the usual RS-spec gaping air intakes, 21-inch wheels, sport exhaust and carbon fiber ceramic brakes. Combine all that goodness with dynamic ride control, an adaptive air suspension and torque-vectoring Quattro all-wheel drive, and we have no doubt that this thing will scare off every other station wagon in the parking lot. (Well, except maybe that Mercedes-Benz E63 AMG. Woof.)
