Next Audi TT glimpsed, same as it ever was?

Audi has teased the new TT coupe ahead of its Geneva Motor Show reveal with renderings and video, but now, what appears to be a photo of the new two-door has leaked onto the web, courtesy of Autofans.be. And if you're thinking, "Well, jeez, that looks familiar," you definitely aren't alone. Aside from the new lighting character in the taillamps, everything you see here looks pretty much unchanged from the old car. Of course, the front should get a nice freshening, and that interior should be super-high-tech. We'll reserve final judgments until we see the new TT live in Geneva next week.

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.

2014 Audi R8 V8

Where to even begin with the Audi R8 V8.
Let's start with the Ferrari 458 Italia, a car that doubles the base price of the Audi. It's much more fun to drive than it is to talk about; discussions among enthusiasts usually begin with someone saying, "It's amazing!" and end with everyone else agreeing. Opposite that is the vast, swirling nebula of cars that are often more fun to talk about than they are to drive.
In between, there are very few cars that are as fun to discuss as they are to drive, and this Audi is one. It's a car that challenges our notions about its actual competitive set and, even better, its philosophical competitive set, its driving experience, its price, its future, its present viewed from the future, and its verifiable and/or potential pedigree.
