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.

24 Hours of Le Mans an on-and-off love affair

There was little usual about this year's 24 Hours of Le Mans - intermittent rain in the weeks before the race meant cars didn't get on track as much as they wanted, and intermittent rain during the race meant cars went off track a lot more than they wanted. The race started with a wet track, and one of the records broken because of the random downpours was the number of times the safety car led the field - 11 times this year - although the record of two hours and 53 minutes of lapping behind the safety car, set in 2011, was not eclipsed.
None of that served to dampen the action. With little more than an hour left in the race there were cars still only a few seconds apart fighting for position, leads still changing because of pit stops and everyone drafting anyone they could.
Things didn't go the usual way up front, either - well, not exactly...

More next-gen Audi TT details revealed

We still only have rumors about the third-generation Audi TT said to be scheduled for launch in late 2014, but based on a report in Car and Driver, we know a tiny bit more about it. The base engine will be the 2.0-liter turbo four-cylinder with direct injection, but horsepower is said to be 220 horsepower - that would make for a nine-hp jump over the current output. The TTS would get an even larger power boost, going from 265 currently to 300 hp. The TT RS would stick with it's 2.5-liter five cylinder, with output increased from 360 to 380 hp. If Audi includes a nice dose of the go-light engineering involved in the TT Ultra Quattro, these horsepower numbers might be even more impressive.
As with the TT concept and first-generation production car, though, it sounds like the brand is concentrating on aesthetics. It's been widely reported that Audi wants to reclaim the juju conjured by the original TT, and while we still don't know what that means outside, CD reports that the interior gets simplified, "futuristic-feeling" styling thanks to instruments served up on a TFT screen. Remember, the first Audi TT had a cockpit that Car magazine dubbed simply, "The Cabin."
About a year after the coupe comes, the Audi TT Roadster will show up and should be joined by the next A5. The news for the next version of the subtly beautiful coupe is the arrival of a plug-in hybrid with torque vectoring via an electric motor for the rear axle. Beyond that is wilder speculation of an A9, which might be called Q9, and which was the four-door-coupe flavor of the month two years ago when it was possibly going to share a platform with the Lamborghini Estoque. According to the CD story, the thinking now is around "a combination of fastback and crossover proportions," a two-fer we've yet to see any carmaker pull off without making us go, "Oh. I see."
