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 A3 E-Tron launching at $51,500 in Germany

Audi has put a price tag on the A3 Sportback E-Tron plug-in hybrid, for which presales begin this month in Germany. To get your hands on one of these little guys, Audi is asking for ˆ37,900, or about $51,537 according to current exchange rates. Of course, the base MSRP doesn't include any incentives, but in Germany, those savings would come from certain annual tax exemptions that apply to PHEVs. Buyers in other countries might have more luck in getting into an A3 E-Tron for less. Audi lists its most important markets for the A3 E-Tron as Germany, Sweden, Norway, Holland, the UK and, despite no firm date for the car's arrival here, the United States. These countries, according to Audi, are where buyers are willing to spend their green (or the more colorful banknotes of Europe) on green cars. These places also enjoy nice things, or in Audi's words, "They appreciate the classic strengths of the Audi brand: high-end technology, uncompromising workmanship, sportiness and elegant design." In Germany, Audi will sell the A3 Sportback E-Tron at select dealerships. The service departments of those 100 or so dealers will get special training to work with the high-voltage technology used by the plug-in hybrid. These locations will also feature free-to-use charging stations for customers. The Audi A3 Sportback E-Tron's lithium-ion battery stores 8.8 kWh of juice, and is supplemented by a four-cylinder, 1.4-liter TFSI engine which works parallel to the electric motor. Total output is 204 horsepower and 258 pound-feet of torque, directed to the front wheels via a six-speed S Tronic transmission. The car can reach 60 miles per hour in 7.6 seconds and has a top speed of 138 mph. It can travel of to 31 miles on battery power alone. Deliveries for the 2015 Audi A3 Sportback E-Tron will begin in Germany and Central Europe this winter.

Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.
