Audi planning A7 powered by fuel cell?

Back in March, Volkswagen AG CEO Martin Winterkorn voiced his doubts about the cost and infrastructure associated with building hydrogen fuel cell vehicles, but according to Autocar, that isn't stopping Audi from developing a fuel-cell version of the Audi A7. While we're inclined to take this report with a grain of salt, this wouldn't be the first time a VW executive has made seemingly damning statements about electric powertrains that later proved to be incorrect.
After speaking with Audi technical chief Wolfgang Dürheimer, Autocar reports that Audi is building a fuel cell A7 that is expected to be ready for testing by August. Like the electric E-Tron and natural-gas-powered G-Tron models, the hydrogen fuel cell Audis could, if produced, carry their own "tron" nomenclature.

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.

2014 Audi RS7 [w/video]

The subject of what makes up a true "supercar" is a difficult one, fraught with personal connotations and the rare ability to bring close colleagues into heated confrontation with one another in the blink of an eye. I say this because, while the 2014 Audi RS7 most certainly does not make the supercar cut on a few levels to my way of thinking - not rare enough, expensive enough or wearing an appropriately evocative body - it is unquestionably an "everyday supercar" of remarkable ability. And, pertinently, it is one that proved willing to ply its trade in every version of winter that Michigan had to offer it.
I had winter four ways during my week-long loan with the RS7. A period of crisp temperatures and dry roads, presided over by light blue skies as wide as the horizon, soon gave way to spitting, freezing rain blanketed in slightly misleading warmer air. Then there was snow. Not the massive blanket we saw in the first week of the New Year, but more than enough to see my neighbors stocking up on Ice Melt and replacing their shovels for the season. Finally, temperatures dropped to the mid teens, cottony snow compressed into a hard pack and all residual moisture on the mostly cleared roads morphed into the very slickest of ice. Timeless curses were uttered by cranky commuters in smoking breaths. Pure Michigan.
