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.

597-hp Audi RS7 Performance coming to US

The Audi RS6 Avant and RS7 Sportback certainly aren't hurting for power. Their 4.0-liter, twin-turbo V8s offer mountains of muscle as tall as the Alps. However, the engineers at the Four Rings are pushing those peaks just even higher for the new Performance versions of the pair. Tweaks to the engine management, bring horsepower up to 597 ponies and 516 lb-ft of torque. Temporary overboost can take the twist to 553 lb-ft, though. This high-performance duo can haul passengers with aplomb by hitting 62 miles per hour in 3.7 seconds – two tenths quicker than a regular RS. Even more impressive, the 12.1-second run to 124 mph also takes 1.4 seconds less than the standard version. Top speed remains the same 155 mph, but the optional Dynamic Package takes off the limiter to let the RS6 reach 174 mph and the RS7 go 189.5 mph. The eight-speed tiptronic remains from the standard RS versions, and it routes power through the Quattro all-wheel drive system with a 40:60 front-rear split. An optional sport differential at the back can also provide some extra assistance. Both Performance models come standard with an adaptive air suspension, but for those willing to spend a little more a stiffer RS sport suspension plus with Dynamic Ride Control is available, as well. The Performance pair launches in Germany at the beginning of November, but there's reason to get excited in the US, too. Audi spokesperson Mark Dahncke confirms to Autoblog that the RS7 Performance is coming here. More details about it should arrive around the Los Angeles Auto Show, he said.

Fuel consumption remains unchanged at 9.6 and 9.5 liters per 100 kilometers (24.5 and 24.8 US mpg), respectively, corresponding to 223 and 221 g CO2 per km (358.9 and 355.7 g/mi). These are best-in-segment figures.

Next-gen Audi Q7 to debut in Detroit

Audi's public relations team must really be getting fed up with research and design boss Ulrich Hackenberg. Aside from basically confirming that the next Audi R8 will share its bones with the Lamborghini Huracán and noting that it may take advantage of the Asterion Concept's hybrid powertrain technology, he's now let slip that the second-generation Q7 will arrive in January at the 2015 Detroit Auto Show.
"If you make a trip to Detroit, you'll see it," Hackenberg reportedly told Indian Autos Blog during Paris Motor Show festivities.
That's a bombshell, particularly as we've heard plenty about its potential powertrain technologies, including spy shots of diesel-powered models, plug-in-hybrids, sporty SQ7s and electric turbochargers, but there's been absolutely nothing concrete about when and where the car would debut.
