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.

More details on next Audi A4 mooted, including PHEV

With just under two more years until the next-gen Audi A4 hits the streets, it's not surprising that details are starting to leak out. The Brits from Autocar are reporting some information on the 2015 A4, although it isn't clear where any of it came from.
The most substantial news might be in regards to the plug-in hybrid version of the car. We've known for a couple years now that an A4 PHEV was being planned, but the report indicates that a trio of plug-in configurations are being planned, equipped with a 2.0-liter gas engine, a 2.0-liter diesel engine or a 3.0-liter supercharged V6. All engines will be paired with an eight-speed automatic transmission, and the A4 plug-in is said to have an all-electric range of up to 31 miles.
In terms of styling, the next A4 shouldn't stray too far away from Audi's current design language, but it will introduce a new version of the automaker's signature grille. Despite being about the same size as the existing A4, the fifth-generation model will drop some pounds thanks to various weight-saving techniques with the most obvious being aluminum body panels. Based on this info, we should see the A4 sedan and wagon in April 2015, an Allroad later in the year and a redesigned A5 lineup hitting the scene in 2016.

Road & Track names its 2013 Performance Car of the Year

Road & Track recently staged its first annual Performance Car of the Year test, pitting 13 new and updated performance cars against each other on track, then graduating the top six to a road test before picking a winner.
