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.

2016 Audi A6 to start at $46,200*, A7 begins at $68,300*

Audi has announced pricing on the new A6 sedan and A7 four-door coupe, with the former starting at $46,200 for a 2.0-liter, turbocharged four-cylinder and front-wheel drive. Of course, things can and do climb rapidly from there. Adding Quattro all-wheel drive to the four-cylinder model bumps the price up $2,200, while moving from the base Premium to the mid-level Premium Plus trim will add $3,700, regardless of the drivetrain. Speaking of that Premium trim, it's only available on the 2.0-liter A6. Every other variant starts with the Premium Plus. At that point, the cheapest six-cylinder you can get is the $57,400 model, while the diesel-powered A6 TDI starts at $59,500. Moving up to the top-end Prestige trim bolsters the price by $4,200, for both engines. If you fancy the sleeker lines of the A7, the entry-level 3.0-liter Premium Plus can be had for $68,300, while the TDI runs $70,400. While the starting price is higher than the A6, adding the Prestige trim is more reasonable, with both engines demanding $2,650 for the top-tier equipment level. And of course, we can't get away without mentioning Audi's high-performance models. A base S6 Premium Plus begins at $70,900, while the Prestige is $75,300. The S7 and RS7, both of which are limited to the Prestige trim level, start at $82,900 and $108,900, respectively. None of the above prices include the standard $925 destination charge.

2014 Audi A7 TDI

If you're a frequent reader of car reviews (my money says you are), you've no doubt come across prose about how a car "checks all the right boxes." It's a common phrase - I'm guilty of using it myself. And I'm about to use it again.
You see, I've just spent a week with the 2014 Audi A7 TDI, shown here against the backdrop of sunny SoCal, even though my stint was spent slopping through this absolutely wonderful winter we've been having in Detroit. If you're one of our podcast listeners, you've already heard me wax poetic about the A7 TDI, and the more I reflect on this diesel darling, the more I firmly believe that this car absolutely, without a doubt, checks all the right boxes.
Well, almost all of them, anyway.
