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 updates the RS3 hatch to sedan specs, but we still aren't getting it

As great as the upcoming Audi RS3 sedan looks and sounds, we're still a bit jealous of the Europeans and others who get the five-door Sportback version. And now even more so, because for 2018 the RS3 Sportback is being updated to match the specs of the RS3 sedan that debuted last fall at the Paris Motor Show. We'll see the revised extra-hot hatch next month in Geneva. Even though we haven't had a chance to get behind the wheel of either model, the raw numbers alone get us excited. An updated Quattro all-wheel-drive system, a 400-horsepower turbocharged inline five-cylinder engine (up from 362), and a seven-speed dual-clutch transmission will send the 2018 RS3 hatch from 0 to 60 mph in 4.1 seconds. That puts it in Porsche 911 and Chevrolet Corvette territory. Other improvements include a wider track to fit wider rubber, a lowered and stiffened suspension, and a larger set of brakes. Carbon-ceramic front rotors will again be available, like they are on the sedan. Inside, the RS3 comes with a boost pressure indicator, an oil thermometer, and a lap timer. Audi's Virtual Cockpit fully digital instrument panel is available as an option, and one we highly recommend. Aside from all of the performance and tech upgrades, the RS3 has a number of changes to the interior and exterior design. Black Nappa leather sport seats are standard, with special contoured RS sport seats available as an option. Lighting elements have been updated to match those of the restyled A3 and S3, the front fascia has been sharpened, with larger intakes on the bottom corners of the bumpers, a slightly more aggressive front splitter, and the Quattro logo emblazoned on the bottom of the grill. Out back, the car gets two large exhaust tips compared to the S3's four outlets. The overall design is typical Audi: handsome, but conservative. The RS3 sedan goes on sale in Europe in April with the Sportback following soon after. We'll have to make do with the sedan version, which is expected to arrive here next year. The only Sportback model Audi offers here from the A3 family is the plug-in e-tron model, and we don't expect that to change any time soon. But we can dream. Related Video:

Audi's new 1,000-hp hybrid pulls like a freight train

Audi's latest plug-in hybrid handles like it's on rails, and pulls like a freight train. That's because it's a train, and literally rides on rails. The vehicle in question is a locomotive which the German automaker developed for its main factory in Ingolstadt incorporates over 11 miles of railroad tracks, along which are transported parts and completed vehicles to be moved around the site. To carry out those duties, Audi teamed up with French manufacturer Alston to deploy a new hybrid locomotive on premises. The locomotive features a plug-in hybrid propulsion systems capable of running on electric power alone for two hours at a time, and can be plugged in to recharge during down-time. The upshot is that it not only pollutes less overall, but can be run inside warehouses more safely. When the power runs out, the electrical system is backed up by a diesel engine. Audi reports that 15 trains arrive at the factory every day. It employs 17 locomotive drivers on site. And each locomotive runs for 3,800 hours each year. Whether we can take Audi at its word when it comes to diesel emissions or not, the company claims that the new hybrid locomotive cuts its carbon emissions by half, taking 60 tons of CO2 out of the atmosphere each year. 10/30/15 Ingolstadt Hybrid locomotive at Audi plant in Ingolstadt This Audi drives on rails: A 1,000 horsepower plug in hybrid locomotive manufactured by Alstom replaces the plant locomotives previously used at the Audi plant in Ingolstadt as of today. This means that components and finished Audi models will now reach the plant's loading stations in a more climate friendly way. "Our goal is all-round sustainable logistics," stated Johann Schmid, head of the Audi plant railway in Ingolstadt. "The new railway technology allows more economical, energy-efficient and low-emission rail transport. In connection with the latest chassis technology, the plug-in-hybrid locomotive sets new standards in shunting and rail transport." The complete automobile plant in Ingolstadt includes 18 kilometers of railways. Every day, 15 goods trains arrive at Ingolstadt North railway station for Audi – loaded with pressed parts, engines and transmissions, as well as cars from other Audi sites that are ready for delivery to customers. And cars produced in Ingolstadt also start their journey to customers by rail. 17 Audi locomotive drivers work at the plant railway. One of their tasks is to allocate the wagons to the various plant buildings.
