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.

2014 Audi A3 Cabriolet cleans up the Messe [w/video]

If we're being honest, the outgoing Audi A3 Cabriolet never really flicked our Bic. That was just fine, of course, because Audi never brought it to North America. This new model, however, might have a different future.
And while Audi has yet to officially decide on this car's North American future, this Frankfurt Motor Show debut clearly has a better sense of proportion and aggression to it, and we're excited about its powertrain solutions, too. For the European market, Audi is promising TFSI gasoline engines in either 1.4- or 1.8-liters, along with a 2.0-liter TDI diesel, all being available in front- and all-wheel drive. Audi has also confirmed its first-ever S3 Quattro Cabriolet, which figures to combine a quick 18-second top drop and its hard-hatted sibling's even quicker 296-hp 2.0-liter turbo.
Even though Audi has been better about bringing its high-performance models to North America and has a new emphasis on growing its A3 business in our territories (including a US-minded sedan bodystyle), we would still be a bit surprised to see an S3 Cabriolet popping its entry-level top in dealers in a couple years' time. Having said that, we do think this A3 Cabriolet is almost a lock. Be sure to take a good, long look at our gallery, video and the official press release below.

Audi Allroad Shooting Brake showcar is a 124-MPGe hybrid E-Tron

The leaked images of the new Audi Allroad Shooting Brake that came out Friday showed us what the show car will look like, but it wasn't until the official press release came out today that we learned just how much E-Tron is hiding in its powertrain. Turns out, it's a lot. An 8.8-kWh lithium-ion battery can power the car for over 31 miles. The Allroad Shooting Brake is powered by a hybrid (gas-electric) powertrain that can put out a total of 300 kW of power (479.42 pound feet of torque) and, under the right circumstances, get the fuel efficiency equivalent of 123.8 mpg US, Audi claims. The gas side is made up of a 2.0-liter four-cylinder turbocharged engine, and then there's an electric motor on each axle. An 8.8-kWh lithium-ion battery can power the car for over 31 miles on battery power alone. There are three drive modes (EV, Hybrid and Sport). This is also the first time Audi has put its Allroad and E-Tron "form languages" together, which means this E-Tron Quattro "is not limited to paved roads" and can handle "light off-road conditions." The two electric motors help bring the car from 0-62 miles per hour in 4.6 seconds on up to a top speed of 155 mph. Audi has paid attention to shaving weight from the 3527-pound, four-seater, including making the wheels out of carbon-fiber reinforced polymer (CFRP) and using an aluminum underbody panel. We described some of the concept's visual hints in the original post (Q1?), and now Audi says that the car contains "a host of visual elements of future sports car models" (TT?). We will get our first real glimpse of the Allroad Shooting Brake show car at the Detroit Auto Show early this week, so look for live pics then, especially of the interior that is supposed to be reminiscent of an airplane and a user interface panel that is said to work like a smart phone. In the new press release, Audi's Ulrich Hackenberg said the Allroad Shooting Brake represents, "a concrete look into the near future," and we're totally fine with that. Crossover in a compact package: The Audi allroad shooting brake show car Crossover concept car is highly functional for recreational sports Powerful and efficient hybrid drive features two electric motors Prof. Dr. Ulrich Hackenberg: "A concrete look into the near future." Sporty, compact and versatile: It is with these attributes that the Audi allroad shooting brake makes its debut at the North American International Auto Show (NAIAS) in Detroit.
