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 Prologue concept drives itself to CES with updated powertrain

What's the point in crafting a one-off concept car if it only gets to stand in the spotlight at one show? That's what automakers have been asking themselves recently, and the answer has, generally speaking, been to repaint their show cars, give them a bit of new tech and put them back on center stage. And the latest to do so is Audi, which has given its Prologue concept a new lease on life. The Prologue was originally unveiled at the Los Angeles Auto Show less than two months ago, showing the way forward for the future of Audi design, in an elegant coupe form that looked ready to take on the Mercedes S-Class Coupe. We even got a chance to drive it around the streets of LA, and when we did, we marveled at the concept's advanced infotainment system that caters a range of personal preferences according to who's on board. "It's easy to see how this could even reach for chauffeured, or autonomously driven vehicles" in the future, we said at the time. And it turns out Audi was on the same page. At CES this year, Audi has brought back the Prologue concept, given it a darker coat of grey paint, a grey-tone interior (instead of the previous shades of brown and tan), a fresh set of wheels and equipped it with the autonomous tech the German automaker has been at the forefront of developing. Though other automakers have been fitting their self-driving prototypes with all-electric powertrains, Audi kept the 4.0-liter twin-turbo V8 in place – but fitted it with a hybrid assist to drive output up from an already prodigious 605 horsepower and 516 pound-feet of torque to an even more impressive 677 hp and 701 lb-ft, dropping the 0-62 time down to 3.5 seconds. Now that's the kind of "piloted driving" tech (as Audi calls it) that we can get behind.

Autoblog gets ready for Le Mans with an R8 road trip and Allan McNish

This car is the master link between what Audi does on the race track and sells on the road.
We're attending the 24 Hours of Le Mans with Audi and we figured we'd make the world's biggest endurance race even more interesting by driving from Munich to Le Mans in an R8. We've also had a brief chat with Audi driver Allan McNish, and if you haven't already, check out all the multimedia ways to enjoy the next four days from the Circuit de la Sarthe, then read on.
