Refreshed Audi A6 gets ready for Paris debut

The Audi A6 remains a solidly luxurious choice in the deeply competitive executive sedan segment, duking it out with the Mercedes-Benz E-Class, BMW 5 Series and Lexus GS, among others. Having been on sale since 2011, though, it's starting to become just a tiny bit stale. Cue the refresh.
Expected to make its debut in October at the 2014 Paris Motor Show, the long-roof Avant/Allroad variant shown here gives us our first glimpse at some of the tweaks Audi has in store for its A6 range as a whole.
In general, this is pretty standard refresh stuff - new headlights that retain the same general shape as the current car but add a new DRL pattern, while there are also some subtle tweaks to the front fascia. The rear taillights have also been freshened (although as only the A6 sedan is sold in the US, it's likely the taillights we see will be different), and some minor changes have been made to the rear bumper. According to our spies, the cabin and MMI infotainment system could see some tweaks, while the oily bits under the hood could be in for for some minor changes as well.

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 previews sleek crossover concept ahead of Beijing debut

With the Beijing Motor Show approaching just a couple of weeks down the road, automakers have begun announcing the concept cars they have in store. Nissan has a new sedan concept coming, Lexus will reveal the production NX crossover and Citroën has a tempting sports sedan concept lined up for the Chinese auto expo. And now Audi has hinted at what it has in store.
Revealing only a trio of renderings with no details to accompany them so far, Audi appears to have a new crossover concept in the works. Referred to only as the Audi Showcar Beijing 2014, the brief calls for a five-door crossover with a rather coupe-like roofline, rugged lower body cladding and a flexible cabin with quad bucket seats.
The form bears telltale similarities to the new TT, suggesting that this concept could be a further evolution of the Allroad Shooting Brake concept that Audi revealed in Detroit. If put into production, we could see it wearing the Q4 badge, giving Ingolstadt a rival to the likes of the BMW X4, Porsche Macan and Range Rover Evoque. However, until Audi tells us otherwise, that's all speculation...
