Audi A3 Clubsport Quattro concept bringing its 525 horses to W?rthersee

It's almost late May, and you know what that means: the last of the snow has melted, the Stanley Cup playoffs are in full swing, the flowers are blooming, and the performance-car faithful are descending on Wörthersee in Austria for the annual GTI-Treffen.
Not only is the Wörthersee Tour (as the automaker calls it) a chance for enthusiasts to show off their rides, it's also a prime opportunity for the Volkswagen Group to show some of its most dedicated customers what it can do. Past meets have given us such notables as the Audi A1 Clubsport Quattro, Volkswagen GTI W12-650 and Skoda Fabia RS 2000 Roadster, to name just a few. And now Audi has emerged as the first VW Group brand to reveal what it has in store.
It's called the A3 Clubsport Quattro, and seems to offer a pretty clear indication of what we should expect of the next RS3. The concept is based on the S3 sedan, but swaps out its 2.0-liter turbo four for a retuned version of Audi's sweet 2.5-liter turbocharged inline-five, retuned to produce a massive 525 horsepower and 442 pound-feet of torque.

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.

VW makes $23K on every Porsche sold, more than Bentley or Lamborghini

It's a good time to be in the luxury car business. In Volkswagen Group's financial report for the 2013 fiscal year, it is revealed that that Porsche enjoyed an operating margin of 18 percent. That means the Stuttgart brand made on average about $23,200 per car sold, according to BusinessWeek. Bentley wasn't far behind, and Audi (which was combined with Lamborghini) posted a 10.1 percent margin. This compares to only around 2.9 percent for the Volkswagen brand.
"Luxury brands are on fire," said Dave Sullivan, an industry analyst at AutoPacific. He said that the average profit margin is between six and eight percent. Brands like Porsche and Bentley have the benefit of competing in rarefied markets. Buyers looking at one their vehicles have fewer models to shop against and don't care as much about price. They can also charge more for options, which further boosts income, according to BusinessWeek.
In a way, we should be more impressed by the continued success from Audi. Its models generally have direct competitors in every segment from the other premium automakers. Plus, their buyers aren't the captains of industry who are shopping for a Bentley. Still, the Four Rings is leading rivals in sales so far this year.
