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.

After Le Mans exit, Audi adds World Rallycross to Formula E and DTM efforts

Back in October, Dieselgate claimed another victim: Audi's FIA World Endurance Championship program. Audi left at the height of its Le Mans racing prowess, having won 13 times overall in 18 years at the famous French race. We didn't expect Audi Sport to confine itself solely to the Formula E and Deutsche Tourenwagen Masters (DTM) series, and so today Audi announced that the company would officially back an existing FIA World Rallycross Championship (World RX) team, EKS, in 2017. EKS was formed by Mattias Ekstrom, who is also a factory Audi DTM driver with a couple of championships under his belt in that series. He's been competing in various rally and touring car series for years, and even snagged a ride in a NASCAR Sprint Cup race back in 2010 at Infineon Raceway. The EKS team came together in 2014, with Ekstrom fielding an Audi S1 EKS RX Quattro. And the team hasn't done too badly for itself; in 2016, it took the driver's and team championships. There's only so much Ekstrom's team as privateers can do to protect its championship from factory-backed teams, so that explains why Audi Sport was happy to step in with full support – including vehicle development supported by the actual motorsport department at Audi. Ekstrom will also continue on as a factory Audi DTM driver. Related Video: Motorsports Audi Racing Vehicles fia audi s1

For Audi, Quattro name means something for hydrogen cars, too

Forget Dueling Banjos. Audi is proposing "Dueling Motors" for its Audi A7 Sportback H-Tron Quattro concept vehicle. All in the name of appropriate pickup, of course. The German automaker, which showed off the concept sedan at the Los Angeles Auto Show last month, is pairing a plug-in electric motor with a hydrogen fuel cell powertrain. Each motor powers two wheels, maintaining the Quattro's all-wheel-drive pedigree. The car's 8.8-kWh lithium-ion battery can drive the car as far as 31 miles on battery-power alone. After that, the water-vapor-spewing fuel-cell engine kicks in. Audi executive Ulrich Hackenberg told Automotive News Europe that the unusual set-up is necessary because the hydrogen fuel cell powertrain alone would only power two wheels while providing an insufficient 136 horsepower. Not exactly sport-sedan material, especially for a car that weighs about 4,300 pounds, even if it is a zero-emission ride. Combined, the two engines give the sedan 231 horsepower as well as a combined single-charge/full-tank range of almost 350 miles. What it all means is that the A7 can go from 0 to 60 miles per hour in less than eight seconds and has a top speed of about 112 miles per hour, and can still dash through the snow.
