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.

Audi mechanic takes owner's S4 home for the weekend

When you bring your car to a dealer, you expect a technician to take it out for a spin, just to make sure there aren't any noises, rattles or other behavior that you may have missed. Maybe they run a few miles along a predetermined test route or take a quick run down the highway. You do not, however, expect a tech to abscond with you vehicle for a full weekend
That is just what happened to Chris Jackson, though, an Audi S4 owner in Calgary. His car was taken to Glenmore Audi - as mandated in his lease agreement - due to an issue with the navigation system. After realizing he'd left something in the car, he swung by the dealer on Saturday to pick it up, only to discover the car wasn't on the dealer's lot.
Naturally, he approached the dealer about the missing sedan.

Coming to America | 2018 Audi RS3 Sedan First Drive

Audi's Quattro division never let us have the giant-killing, all-wheel-drive RS3. Too sophisticated for the US, they said. Too European. And we only make it as a Sportback (that's hatchback to you). You wouldn't like it. You're more SUV kind of people. Others, those in Quattro's special we-like-you countries, bought the RS3 and constantly raved about it, insisting its handling made the Mercedes-AMG A45 look ponderous (because, well, it is), its packaging was terrific, and the noise, they said. The noise. Over and over, the noise. But ex-Lamborghini president Stephan Winkelmann is now the boss and he's brought with him a worldview that Quattro GmbH never had. And despite being busy changing the letterhead to Audi Sport, Winkelmann found time to think about America. And he must like us because he's moved us to the top of the list. Not only will we get the face-lifted RS3, with its new, lightweight five-cylinder turbo motor crunching out 332 pound-feet of torque and 400 horsepower, we'll get it in a crisply styled three-box sedan. And we'll get it first, before even Germany (where it's built). The RS3's 2.5-liter five-cylinder has enough power to hurl it to 62 mph in 4.1 seconds and, thanks to launch control, the ability to do so repeatably. It's coming with a 155-mph top speed that can be raised to 174. It's coming with limpet grip from a rear-biased all-wheel-drive system. It's coming with a seven-speed dual-clutch transmission (and don't ask for a stick shift, because they haven't bothered to engineer one). It's coming standard (for the US) with constantly variable magnetic ride dampers, which replace the base fixed-rate steel spring-and-damper setup. But more than anything else, the RS3 sedan is coming here with that engine. It starts with a sharp braaap as it spins to around 4000 rpm and then a pop and bang that will wake the neighbors. And that's in the quieter default mode. It's like an angry man who always wakes up looking for a fight and, finding he can't get one, barks out the last word anyway. Except it never really goes quiet. It goes less loud, but not quiet. Quiet is not in the repertoire. The engine is what dominates this car and the noise dominates the engine. It's always there, always threatening, menacing, bellowing, barking, or popping and burbling. With a 1-2-4-5-3 firing order, the turbo five is a unique combination of belligerent and sophisticated, raucous and operatic, brutal and smooth, and often all of them at the same time.
