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.

2014 Audi Q5 TDI

I've struggled with diesel technology. It's not that I have a problem with it or dislike it, but rather that I don't particularly understand what stops its wider-spread adoption. Sure, memories of rust-prone, smoky, sluggish and uneconomical Oldsmobile diesels aren't exactly easy to erase from the collective memory of the North American motoring public, but I'd think that a few years into the latest crop of clean diesels, there'd be wider adoption - or at least consumer consideration - by now.
Part of the issue is the still limited number of segments that diesels are available in. The Volkswagen Golf/Jetta TDI is finally getting a challenger in the form of the Chevrolet Cruze Diesel, and the BMW 328d is bringing something new to the entry-level sports sedan, but there are still a huge group of segments where diesel-power has no representation.
The small, luxury crossover realm is not one of those. It has the Mercedes-Benz GLK250 Bluetec, a stylish crossover with a silky-smooth 2.1-liter, turbodiesel four-cylinder that can return the kind of fuel economy that makes people take notice. And while the GLK250 is quite good, economy will only spread the diesel's appeal so far. People need to experience the seat-flattening torque that these mills can produce, and for that, we most humbly recommend the new 2014 Audi Q5 TDI.

Audi prices 2014 A8L TDI from $82,500*

During the Los Angeles Auto Show last November, Audi told us that it would be bringing four new diesel-powered models to the United States this year. The first to arrive is the 2014 A8L TDI you see here, and we've now learned that the big oil-sipper will be priced from $82,500, (*excluding $895 for destination).
The whole new range of diesel models will be powered by Audi's 3.0-liter TDI V6, good for 240 horsepower and 406 pound-feet of torque in this application. Of course, Quattro all-wheel drive is standard, and even in the big A8, the diesel grunt will be enough to propel the long-wheelbase flagship to 60 miles per hour in 6.4 seconds (almost a full second slower than the A8 3.0T we reviewed last fall). That said, the A8 TDI should still be a pretty engaging steer, and considering the fact that this thing will reportedly return fuel economy figures of up to 36 miles per gallon on the highway (24 in the city), a slightly slower launch time is well worth it. (The A8 3.0T tops out at 28 mpg highway.)
Elsewhere in the segment, Mercedes-Benz offers a diesel version of its S-Class flagship, retailing for $93,000 and good for fuel economy figures of 21/31 mpg city/highway. By comparison, the A8 TDI seems like a steal, and we'll be interested to see where the forthcoming BMW 7 Series diesel falls into the class of huge oil-burning barges.
