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.

Startup will make your Audi A4 self-driving for $10k [w/video]

We are on the cusp of the next generation of semi-autonomous driving technology becoming affordable. Adaptive cruise control is already trickling down to the mass market, and the more sophisticated systems found on vehicles like the Mercedes-Benz S-Class are clearly coming, as well. If you're a little adventurous, live in California and drive an Audi, you might be able to upgrade to the next stage of driverless tech even sooner. A San Francisco start-up called Cruise Automation is launching an aftermarket autopilot system called the RP1 for $10,000, with deliveries starting in 2015.
The RP1 is designed for 2012 and newer Audi A4 and S4 models. Although, Cruise CEO Kyle Vogt told Autoblog in an email: "There's no reason we can't expand to other cars, and we will." The system includes a sensor pod on the roof containing cameras, radar and other sensors to scan the road ahead. It then sends data to a small computer mounted on the side of the trunk. The desired inputs are then made by actuators for the steering, brakes and throttle to control the car. A button in the cabin activates the autopilot and controls the desired speed. Not completely unlike Audi's own, developmental, semiautonomous system.
At this point, the RP1 is somewhere between an adaptive cruise control system and an autonomous vehicle. It can control all of the cars inputs and even bring it down to a complete stop and then accelerate again. However, it only works on select highways in California. "We use geofencing to limit the areas of operation to segments of highway in which we've collected enough data to ensure our customers' safety," said Vogt to Autoblog.

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."
