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.

Mercedes considering Audi Allroad rival

The Audi Allroad is something of an anomaly in the automotive world. Its competitors are limited to the recently released Volvo V60 Cross Country and perhaps the far cheaper Subaru Outback. The lifted premium wagon hasn't exactly done great for Audi, only selling a few hundred examples each month. Its best sales year was 2013, and even then, only 5,300 left US showrooms. Despite these limited prospects, word from Australia is that Mercedes-Benz is looking at launching its own competitor to the Allroad. "We are looking at every single niche, so we are studying this [Allroad] at the moment, but it is not confirmed," Matthias Luhrs, VP of sales and a member of the product management at MB, told Motoring.com.au. "We are looking obviously at C-Class and E-Class, but no confirmation at the moment." Fortunately, Luhrs recognizes that the Allroad isn't exactly a smash in the US. "In the US, no matter how long, short, high ... they don't like station wagons," Luhrs said, while adding that the Allroad concept is "developing quite successfully" in Italy and southern Europe. And for those hoping for a lifted C- or E-Class sedan, Luhrs also put the kibosh on that, saying, "We are not studying that." So what does this tell us? Well, it's still far from a sure thing that Mercedes will launch a lifted C-Class or E-Class Estate. And even if the company does go ahead with it, like the rest of the brand's long roofs (E-Class aside), don't expect to see it on US roads.

Audi pins hopes on 2016 R18 Le Mans prototype

Down but not out, Audi is carrying forward its endurance racing program with the new R18 you see here. Unveiled on Saturday at the Audi Sport Finale end-of-season event in Munich, the new LMP1 is billed as the company's its most powerful and efficient race car yet. And it has been thoroughly redesigned to bring the Four Ring brand back to the winner's circle. Though technical details remain a closely guarded secret, Audi says that the latest evolution of the R18 (now apparently labeled sans the E-Tron Quattro) benefits from revised aero, lightweight construction, and "a modified hybrid system with lithium-ion batteries for energy storage, plus an efficiency-optimized TDI engine." That spells the end of the mechanical fly-wheel setup of the previous version, but sticks to the diesel fuel that Audi has championed instead of the gasoline favored by rivals Porsche and Toyota. With all its revisions, Ingolstadt undoubtedly hopes this latest version will perform better than the last. This past season was the worst Audi has endured since 2009. Its sister company Porsche beat it to both the drivers' and manufacturers' titles in the FIA World Endurance Championship and to the winner's circle at the 24 Hours of Le Mans. That marked the second straight year of defeat in the championship, following Toyota's domination last season, and marked only the third time Audi was defeated at Le Mans since 2000, following Bentley's win in '03 and Peugeot's in '09. In order to avoid costly inter-agency arms race, Audi and Porsche have agreed to each field two entries instead of three in both the championship and the headline race in Western France. Audi has yet to confirm its driver lineup, but Porsche has revealed its lineup consisting of defending champions Timo Bernhard, Brendon Hartley, and Mark Webber in one car, and Romain Dumas, Neel Jani, and Marc Lieb in the other. That leaves out the Le Mans-winning trio of Nico Hulkenberg, Nick Tandy, and Earl Bamber, with the former already counted out due to an F1 conflict. More powerful and efficient than ever before: Audi R18 celebrates world premiere in Munich - New hybrid race car for the 2016 Le Mans 24 Hours - Unchanged driver line-up in the DTM - High demand for new Audi R8 LMS GT3 sports car The brand with the four rings will be entering the 2016 motorsport season with the most powerful and efficient race car Audi has ever built.
