Audi may add plug-in hybrid A6, A8 and Q7 to range [w/poll]

Audi could be getting even more diverse with its powertrains for the A6, A8 and Q7, moving beyond offering just gas- and diesel-powered models and adding plug-in hybrid variants of the three luxury vehicles. The report comes from Indian Autos Blog, which spoke to Dr. Ulrich Hackenberg, Audi's research and design chief, who confirmed the PHVs.
The next-generation Q7, due in 2015, will be the pioneer for the full-size PHV movement from Audi, although the A3 Sportback E-Tron (shown above) will precede it. The move toward plug-ins by Audi is a big step, as the German marque has stayed quite firmly in the diesel camp, outside of its racing efforts. It's developed a few E-Tron cars over the years, including a version based on the R8, although it wasn't until recently that production of the electric sports car became serious again.
It's believed that this hesitance to really dive into the PHV market is why Audi sacked former research and design boss Wolfgan Dürheimer, with IAB speculating that his approach was too conservative.

Audi Canada surprises out-of-warranty owners in a good way

One of the worst parts about going to a dealership is sitting around waiting for the courtesy shuttle to show up and transport a group of strangers to their places of work or homes. Well, Audi of Canada found a nice way to surprise customers who brought their out-of-warranty vehicles in for a scheduled Health Check by replacing dealer's normal shuttle with a 2014 Audi R8 V10.
The R8, painted to resemble a safety car or police car, gave the customers a ride home - even stopping at a coffee shop along the way. Needless to say, the stunt got plenty of attention from passers-by and was quite a hit with the Audi customers, too. Scroll down to watch video of the customers getting the ride of a lifetime, which we're sure left some of the in-warranty customers at least a little jealous as they drove off in dealer loaner cars.

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.
