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's next R8 snapped running the 'Ring nearly naked

Following the debut of the Lamborghini Huracán, work is now well well under way on its cousin. That, of course, would be the next-generation Audi R8, the followup to the model that put Ingolstadt on the supercar map in 2006 and has been on the market ever since. That's an eight-year lifespan, though to be fair, for 2014 it has gotten a pretty meaningful update. Still, that's a long lifecycle, even if the Gallardo with which it shares its underpinnings was around even longer. In other words, it's about due for replacement.
Fortunately, that's just what Audi has in the cards. We've seen prototypes wearing heavy camouflage lapping the Nürburgring a couple of times over the past few weeks, but now it's been snapped nearly completely undisguised, with largely bare black bodywork giving us an even better look at what to anticipate.
So what are we looking at here? A sharper-looking take on the existing design, for starters, so onlookers and customers alike shouldn't have any trouble identifying this as an R8 - but a newer one at that. It seems to take some cues from the new TT, particularly around the headlights, with more squared-off elements throughout. There's an adaptive rear wing poking out the back and more pronounced side-blade intakes between the doors and the rear wheels, which themselves are wearing ultra low-profile rubber.

Volkswagen finds CO2 'irregularities' for 800k vehicles

The latest issue for Volkswagen affects another 800,000 vehicles, and this time its for irregularities in CO2 emissions certifications. VW estimates this issue could cost the company $2.2 billion to fix. The company officially makes no specific mention of which engines are covered, the models they are in, or even where they are located. VW discovered the situation during its ongoing internal investigation, and, according to the automaker, "it was established that the CO2 levels and thus the fuel consumption figures for some models were set too low during the CO2 certification process." Most of the affected vehicles are diesels, and the company is now reaching out to "the responsible type approval agencies" to figure out the next step. While VW isn't officially confirming which models and engines are involved, Automotive News reports that it affects some 2012 and later VW, Audi, Seat, and Skoda models with the company's 1.4-, 1.6-, and 2.0-liter diesel engines, as well as the 1.4-liter ACT gasoline engine. The issue mainly affects vehicles sold in Europe. "The Board of Management of Volkswagen AG deeply regrets this situation and wishes to underscore its determination to systematically continue along the present path of clarification and transparency," CEO Matthias Muller said in the announcement. Volkswagen Group of America spokesperson Jeannine Ginivan was able to provide some further clarification to Autoblog. "This is not related to US-certified vehicles," she said. Clarification moving forward: internal investigations at Volkswagen identify irregularities in CO2 levels Matthias Muller: "Relentless and comprehensive clarification is our only alternative." Around 800,000 Group vehicles could be affected Initial estimate puts economic risks at approximately 2 billion euros The Volkswagen Group is moving forward with the clarification of the diesel issue: during the course of internal investigations irregularities were found when determining type approval CO2 levels. Based on present knowledge around 800,000 vehicles from the Volkswagen Group could be affected. An initial estimate puts the economic risks at approximately two billion euros. The Board of Management of Volkswagen AG will immediately start a dialog with the responsible type approval agencies regarding the consequences of these findings. This should lead to a reliable assessment of the legal, and the subsequent economic consequences of this not yet fully explained issue.
