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 R8 bids adieu with the 570-hp Competition in LA

Audi is saying auf Wiedersehen to the first-gen R8 at the Los Angeles Auto Show in the best way possible - the even more powerful, limited edition 2015 R8 Competition. This might be the vehicle's swansong, but it's going out with a bang.
Audi is sending just 60 of these supercars to the US, and the heart and soul is a beefed up version of the 5.2-liter V10 from the V10 Plus model. The mill now makes 570 horsepower, a 20-hp boost, and is mated to a seven-speed, dual-clutch S Tronic gearbox. Audi claims that the potent package shoots the Competition to 60 miles per hour in 3.2 seconds and to a max speed of 199 mph.
The extra ponies might be enough for some, but Audi really wants to make the Competition something special. Matte carbon fiber pieces replace areas around the car, including the rear spoiler, side slides, front spoiler, rear diffuser and center console. For contrast, the wheels and exhaust pipes are painted in high-gloss black. Ceramic brake discs should be a useful aid with deceleration, too.

2015 Audi TT's digital gauge cluster to spread throughout lineup

File this one under: "makes sense to us." According to Car and Driver, the slick new gauge cluster found in the 2015 Audi TT will expand to other models in the automaker's lineup. In the near term, expect the tech to make its way into the next R8 supercar (with a special performance display for that model), as well as the upcoming, all-new versions of the A4 sedan and Q7 crossover.
Audi's new customizable gauges first debuted at this year's CES - it uses a 12.3-inch TFT display, and, while similar to the systems found in the Cadillac CTS, XTS and Mercedes-Benz S-Class, this system has the ability to show full-screen, three-dimensional maps. We had a chance to check out the new display in-person at CES, and found it to be impressive, though we're curious to see how distracting it is while driving.
Car and Driver says the system is still undergoing small tweaks before Audi officially launches it in the TT later this year. From there, the display will be standard in the R8, but Audi is unsure about whether or not to offer it as a standalone option in the higher-volume A4 and Q7 models.
