Audi reveals new beefed-up A8 L Security

Audi claims is the lightest armored vehicle of its kind.
If there were ever a sedan that deserved the descriptor of "luxury," surely it's the Audi A8. Particularly in long-wheelbase form. But for many of Audi's wealthy customers around the world - namely those in developing markets - there can be no greater luxury than security. And for just those customers, Audi has announced the new A8 L Security.

Audi A7 getting nip and tuck

It's been less than two years since the Audi A7 first went on sale in the US, but European buyers have been able to enjoy the sleek and stylish hatchback for twice as long. As such, Audi is preparing to give its A7 a mild refresh with tweaked exterior styling, but we're also expecting some of the features found in the all-new 2015 Audi A8 to possibly trickle down to the A7.
From what we can tell in these spy shots, the A7 is getting a minor facelift that includes a restyled front fascia and new headlights, which will likely boast Audi's new Matrix LED system. At the rear of the car, similar changes have been made with a fascia that now gets integrated outlets and different taillights that have a Lamborghini-like display.
Not apparent in these images - but still a good bet for production - we'd expect to see the new A7 get some of Audi's updated engines or new driver assist technologies. No definite word as to when we'll be seeing the refreshed A7 in person, but considering how close to production ready as this car seems to be, our bet is on the upcoming Geneva Motor Show.

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.
