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 R8 V8

Where to even begin with the Audi R8 V8.
Let's start with the Ferrari 458 Italia, a car that doubles the base price of the Audi. It's much more fun to drive than it is to talk about; discussions among enthusiasts usually begin with someone saying, "It's amazing!" and end with everyone else agreeing. Opposite that is the vast, swirling nebula of cars that are often more fun to talk about than they are to drive.
In between, there are very few cars that are as fun to discuss as they are to drive, and this Audi is one. It's a car that challenges our notions about its actual competitive set and, even better, its philosophical competitive set, its driving experience, its price, its future, its present viewed from the future, and its verifiable and/or potential pedigree.

Audi S8 Plus packs 605 horsepower

Audi doesn't offer an RS 8, and probably never will. But with the release of the new S8 Plus, we wonder if it will ever have to. Because Ingolstadt's new flagship performance sedan packs a mighty punch. "Plus" doesn't even begin to describe the enhancements Audi and Quattro GmbH have wrought on the ultimate new version of the A8 sedan. Power is increased from 520 horsepower to 605, besting anything else in its class. Only the Mercedes S65, which packs four more cylinders and two additional liters of displacement, offers more horsepower. Torque is quoted at 516 lb-ft – a gain of 35 – and can deliver up to as much as 553 lb-ft in overboost. That bests any eight-cylinder performance sedan save the S63. The force-fed V8s in the Jaguar XJR, Maserati Quattroporte, and outgoing Alpina B7 don't stand a chance. All that muscle translates to a 0-62 time quoted at 3.8 seconds. Top speed is governed as usual to 155 miles per hour, but can be derestricted to nearly 190 with the Dynamic package that comes standard in Germany – one of the few places where top speed actually matters. Carbon-ceramic brakes keep all that power and pace in check, nestled inside 21-inch wheels. Naturally, Audi gives the S8 Plus a wide array of visual upgrades inside and out to set it apart from "lesser" versions, and is offering it in an exclusive matte silver finish. Of course none of those enhancements come cheap. In its home market come the end of November, Audi will charge 145,200 euros for the S8 Plus, representing a 28k premium over the existing S8. That also places this as the new top of the line, commanding a higher price than even the long-wheelbase, dozen-cylinder A8 L W12. We're waiting on word as to whether Audi will bring the new S8 Plus to America, where it would likely similarly cost over $140k. The pinnacle of sportiness – the new Audi S8 plus - Highest powered sport sedan in the premium segment - 4.0 TFSI engine outputs 445 kW (605 hp) and up to 750 Nm (553.2 lb ft) - Zero to 100 km/h (62.1 mph) in 3.8 seconds; top speed of up to 305 km/h (189.5 mph). Audi is making a strong statement with the new S8 plus*. With a power output of 445 kW (605 hp) and a top speed of up to 305 km/h (189.5 mph), the new Audi S8 plus* delivers even more enhanced driving performance. The new top model is reinforcing the brand's position in the segment of premium class sedans. "We have further sharpened our large sport sedan," says Prof. Dr.
