Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

Audi starts new e-gas partnership with Global Bioenergies

Audi continues to try to build its green-car cred with one more partnership to produce synthetic fuels made from renewable resources. The German automaker is hooking up with France-based Global Bioenergies to make a synthetic biofuel called e-gasoline. Audi says making this e-gas "does not create competition with food production and farmland," nipping that argument in the bud. Last summer, Audi opened a power-to-gas facility in Werlte, Germany. That factory produces hydrogen and synthetic methane, which are made from renewable energy sources such as water and excess carbon dioxide. The E-gas plant uses electrolysis to split water molecules into oxygen and hydrogen; those elements will later be set aside to power fuel-cell vehicles but in the near term, the plant will make synthetic natural gas. Audi started delivering e-gas in Germany in the fall of 2013 and estimated that it would make enough of the stuff each year to power 1,500 Audi A3 Sportback G-tron vehicles for more than 9,000 miles. Audi also operates a research facility in Hobbs, New Mexico, with renewable fuel company Joule. That plant produces e-ethanol and e-diesel. Check out Audi's press release about its new Global Bioenergies partnership below. Audi launches strategic partnership with Global Bioenergies Premium carmaker and biotechnology company developing the drop-in biofuel Audi e-gasoline Reiner Mangold, Head of Sustainable Product Development: "Another step closer to carbon-neutral mobility with Global Bioenergies" e-gasoline part of the big Audi e-fuels strategy Audi is launching a strategic partnership with Global Bioenergies. The carmaker will work with the French biotechnology company to promote the development of non-fossil fuels. In addition to the Audi e-gas and e-diesel projects, the research into e-gasoline is part of Audi's persistent efforts to find alternative fuels. Reiner Mangold, Head of Sustainable Product Development at AUDI AG: "We're taking another step closer to carbon-neutral mobility with our partners at Global Bioenergies. We are supporting an innovative technology here which can be used to produce renewable fuel. This process does not create competition with food production and farmland." e-gasoline is part of the overall Audi e-fuels strategy. Audi is already operating a research facility for the production of e-ethanol and e-diesel with its partner Joule in Hobbs, New Mexico. The Audi e-gas plant in Werlte began feeding into the grid a few months ago.

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.
