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 prepping minor refresh for S6

Audi is well underway with testing for all of the refreshed versions of its A6-based sedan. We've already shown you shots of the Euro-spec A6 Allroad (which will wear some of its styling with our US-spec A6 sedan), and now we have some shots of a car that will actually arrive in the United States - the S6.
Like the Allroad, this will be quite a modest refresh, with tweaks to the headlights and taillights, as well as some slightly revised front and rear fascias. The headlights should get a new LED DRL pattern, although we doubt the changes will be much more drastic than that.
As with the Allroad, it seems likely that Audi will make a few very small changes to the interior, while the MMI infotainment system should also see an update. Changes under the hood, though, are more difficult to guess. That said, minor changes could be in store, but don't expect a dramatic increase in power or performance.

Audi highlights headlights on upcoming new R8

Audi is preparing to roll out an all-new R8... but it's not about to reveal the whole thing at once. So in the first in what promises to be a series of teasers, the German automaker is showing off the new supercar's headlights. (Or headlight, we should say, in the singular.) Not unlike the R8 LMX revealed in Paris, the second-generation Audi supercar will incorporate LED headlights with an optional laser high-beam module. Unfortunately since laser headlights are illegal in the United States, the option isn't likely to be offered here. That is, at least, until Audi succeeds in convincing federal regulators otherwise. Although the teaser image above, like the press release below, may shine the light (so to speak) principally on the headlights, the shrouded shape also gives us a (little) bit to chew on. Yes, it will be available in blue, but beyond that we can expect the new R8 to incorporate slightly more angular lines than the model it replaces, with a more pronounced trapezoidal grille up in an overall design similar to the new TT, only more so. But then we already knew that much and more from the undisguised image that leaked out a little over a week ago. Ingolstadt, 2015-02-16 Audi reveals laser headlights for the new R8 - New mid-engine sports car features high-tech headlights - Laser high-beam offers high light intensity and excellent range Audi is revealing the headlights of its new R8* as the first of a number of technology highlights of the top sports car. The R8 uses LED headlights which can be supplemented by a laser high beam lighting module as an option. The new R8 will set new standards among high-performance sports cars – including in its lighting technology. As an option, the latest car development by Audi can be equipped with a laser spot as the high-beam headlight. The special appeal of laser lighting is that it uses high-intensity laser diodes, which generate a lot of light energy from a very small component. Compared to LED high-beam headlights, laser high-beams attain nearly twice the lighting range. Each headlight contains one laser module that operates with four high-intensity laser diodes. This module bundles the four intense blue-light laser beams. Then a phosphor converter transforms the blue light into pure white light. An identifying characteristic of the laser headlights is their blue light signature. Standard equipment in the new R8 includes an LED headlight system.
