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 Nanuk Concept likes Parcour, puts four rings on it

Without a doubt, one of the coolest (and weirdest) debuts from this year's Geneva Motor Show had to be the Italdesign Giugiaro Parcour concept. And ever since the off-road performance coupe with Lamborgini guts made its debut, we've sort of been smitten with it. We figured this neat two-door would be a one-and-done show car, but to our delight, the folks at Italdesign worked with Audi to create this, the Nanuk Quattro Concept, which makes its debut here at the 2013 Frankfurt Motor Show.
Unlike the original Parcour, the Nanuk ditches the high-revving Lambo-sourced 5.2-liter V10 in favor of a twin-turbocharged 5.0-liter diesel V10. That's a beast of an engine, and with 544 horsepower and 738 pound-feet of torque on hand, it means the 4,189-pound, all-wheel-drive Audi can scoot to 62 miles per hour in under four seconds. Of course, being a diesel, it's surprisingly efficient, and we're told the Nanuk can achieve up to 30 miles per gallon.
As much as we sort of hate the term, the Audi Nanuk is a proper coupe-crossover if we've ever seen one, and utilizes the automaker's next-generation adaptive air suspension (the Parcour had a different pushrod arrangement) that offers a range of almost three inches of height adjustment. There's also an integral steering setup, meaning the rear wheels can turn up to nine degrees in the opposite direction of the front rollers, improving maneuverability.

Watch the Le Mans Audi R8 safety car drift during red flag

With open-wheel, prototype, and GT cars so dependent on keeping their tires warm, European series enlist much higher-performance cars than the family sedans that pace the NASCAR field. That also means their drivers need to know their way around a race track. Yannick Dalmas, the driver of the 24 Hours of Le Mans' Audi R8 safety car, proved that point during heavy rains yesterday. The four-time Le Mans champ and former F1 driver had a bit of a moment during the red flag. We don't know if Dalmas was having a bit of fun or genuinely getting out of trouble on the deluged track, but cameras caught him executing an lurid drift that will probably end up in an Audi commercial in the near future. It's hard to tell what section of the track Dalmas went drifting at – it's pitch black in the video – but based on the downward, right-hand bend, we're guessing it was between Tertre Rouge and the start-finish line, maybe in the Esses. You can see the big moment in the video, which generated plenty of cheers from the red-flagged racers and their pit crews. Stick around for the end of the video for Porsche driver Mark Webber's impressed reaction.
