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.

2013 Audi RS5 Cabriolet

The Audi RS5 is a bit of an odd duck in the brand's US lineup. At the moment it is one of only two RS models - the other being the TT RS - atop a pyramid of A and higher-performing S models. It is not, however, the brand's flagship performance model - not even close - that space being occupied by variants of the R8 supercar, specifically the V10 and GT models, and upcoming 560-horsepower RS7.
The RS5 does, however, owe its beating heart to those ten-cylinder R8s, its own 4.2-liter V8 almost identical to those engines save for two fewer cylinders. Outside of the R8, then, the RS5 is the lone bastion of naturally aspirated V8 power in a brand that once happily shoved 4.2-liter V8s under any hood that they would fit. Today, not even the giant Q7 SUV offers a V8. Lastly, the RS5 is not new, except to us, having been on sale in Europe in coupe form the last couple of years.
While Europeans were able to enjoy the hardtop two-door without us, the RS5 Cabriolet is reaching both peoples around the same time: now. We reviewed the RS5 coupe just recently, and having spent some time with the tin-top model myself as well, here is my take on the droptop version of what I consider one of Audi's most interesting models.

Audi to use this telepresence robot to fix cars

Next time you take your Audi in for service, watch to see if a little white stand is following your mechanic around. It's not some new measurement tool for your car; it's a actually a robot being controlled remotely to improve vehicle service. While bots playing a role in building cars is nothing new, the company is taking things a step further in the US by introducing Audi Robotic Telepresence to assist dealer technicians in repairing the brand's vehicles. The droids are already being used in a pilot program at about 18 dealers nationwide with plans to have it at 100 in the near future.
At the moment, ART, as its called, is more R2-D2 than The Terminator. It certainly won't be doing any wrenching on your A4 anytime soon because it doesn't even have arms. Instead, the robot comprises a remote-controlled stand with multiple cameras, a microphone and speakers. The bot is operated remotely by Audi Technical Assistance consultants and Technical Field Managers who can talk back-and-forth with mechanics about vehicle service and help to remotely diagnose problems. The droid is even equipped with a handheld camera and borescope to reach into tiny crevices.
Audi claims that ART is the first system of its kind to directly link automakers with technicians at the dealer level in this way and leads to faster, more accurate service for customers. Scroll down to watch a video of the bot in action and read the release for the current list of participating dealers.
