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.

2015 Audi A3

The five-door Audi A3 hatchback, on sale in the States since the 2006 model year, never earned the respect it deserved. Despite possessing the automaker's well-regarded build quality and a range of strong powerplants (including an excellent diesel option), the entry-level model always played second fiddle to the rest of the Audi lineup, suffering from less innovative technologies and fewer premium options on its list. Many buyers considered it inferior to the rest of the models in the company's showroom. But those misconceptions could be about to change, as Audi is in the midst of introducing its third-generation A3 family to the States with expectations that the range will finally align with the rest of its portfolio.
First to arrive is this new sedan, notable as it is the first time the A3 has been offered as a compact four door. The new bodystyle is positioned as a premium C-segment offering, with its most obvious competitor being the new Mercedes-Benz CLA-Class (BMW has not officially announced a 2 Series Gran Coupe, which would be the third entrant in the segment). The automaker says its "A3/S3 models will be among the most technically advanced Audi products around" and there will be "no sacrificing Audi craftsmanship and premium appointments." To put the automaker's claims to the test, we spent a week with this new sedan in Southern California.

Weekly Recap: Car-pedestrian crashes remained elevated in 2014

The death of American Horror Story: Freak Show star Ben Woolf served as a reminder this week that car crashes involving pedestrians remain a problem, and a new study issued on Thursday reinforced that the situation isn't really getting better. The Governors Highway Safety Association found a slight decline, 2.8 percent, in the number of pedestrian deaths in the first six months of 2014. Fatalities dropped from 2,141 to 2,125 compared with the same period in 2013, though the association says it's a statistical wash when factoring in undercounting. Deaths are still 15-percent higher than in 2009. "The number of deaths remains relatively high and is cause for concern," wrote Allan Williams, who compiled the report and is the former chief scientist at the Insurance Institute for Highway Safety. This is the first look at data from last year, and the National Highway Traffic Safety Administration will issue its full-year results later. The GHSA found some progress on the roadways, as 24 states and the District of Columbia reported drops in pedestrian deaths. In some states, the problem isn't even a problem at all: Nebraska and Wyoming reported one fatality apiece, though large population centers in urban areas are where most accidents occur. "This is a clearly a good news, bad news scenario," Jonathan Adkins, GHSA executive director, said in a statement. "While we're encouraged that pedestrian fatalities haven't increased over the past two years, progress has been slow." Other News & Notes Cadillac previews CT6 during Oscars Cadillac previewed its upcoming flagship sedan, the CT6, in commercials that aired Sunday during the Oscars. As expected, the creased sedan carries on Cadillac's recent design language, and the car in the commercial looks like a larger version of the CTS and ATS sedans. The CT6 will be revealed this spring at the New York Auto Show and launch late this year. It will be assembled at General Motors' Detroit-Hamtramck factory on a rear-wheel-drive chassis, and the CT6 is the first car to use Cadillac's revised alpha-numeric naming scheme. The commercials also kicked off Cadillac's "Dare Greatly" campaign, which is the first with its new advertising agency, Publicis Worldwide.
