CO2-neutral* Audi A3 G-Tron goes on sale in Germany

The Audi A3 Sportback G-Tron has been on our natural gas-powered radar since it was unveiled at last year's Geneva Motor Show. Just before the big show starts up again this year, Audi put the new G-Tron vehicle on sale in Germany today, starting at 25,900 euros ($35,400 US). Anyone who opts for the Audi e-gas fuel card will be able to cruise the Autobahn knowing that their emissions will be CO2-neutral. That's because Audi has built an e-gas plant in Werlte in Lower Saxony, Germany that creates a synthetic methane that is compatible with natural gas from a process that uses "green electricity" to "[bind] as much CO2 as is released when the Audi A3 g-tron is driven in gas mode." Your own A3 G-Tron doesn't burn the carbon-neutral fuel directly, but the automaker will track how much is spent using the fuel card and make sure "that exactly this amount of Audi e-gas is fed into the German natural gas network." Audi charges 14.95 euros a month to use the card. Burning that e-gas in the A3's 1.4-liter TFSI engine can put out 110 horsepower (you can also burn regular natural gas or gasoline) and offers fuel economy of between 3.2 and 3.3 kilograms of gas per 100 kilometers on natural gas Audi A3 g-tron: Advance sales get the green light Ingolstadt, 2014-02-13 Audi A3 Sportback g-tron available to order from February 13 CO2-neutral mobility with the Audi e-gas fuel card Prof. Dr. Ulrich Hackenberg: "Audi e-gas is an important pillar of our sustainability strategy" The Audi A3 g-tron is all set to hit the roads. Advance sales at dealerships in Germany will kick off on February 13. The basic price will be 25,900 euros. Using the Audi e-gas fuel card, customers can opt for Audi e-gas to power their A3 g-tron without impacting the environment if they wish. The Audi A3 g-tron forms part of a new, integrated and sustainable mobility concept from the brand with the four rings. Its 1.4-liter TFSI engine developing 81 kW (110 hp) can be operated using either natural gas, e-gas generated by Audi or gasoline. In pure e-gas mode the g-tron is entirely CO2-neutral. Audi e-gas is a synthetic methane that is produced at the Audi e-gas facility located in Werlte in Lower Saxony, Germany – the world's first industrial power-to-gas plant. An A3 Sportback g-tron fueled by Audi e-gas is currently the most environmentally friendly form of long-distance mobility.

2016 Audi TTS Roadster opens up for all to see

The five-door Sportback concept may be garnering the lion's share of attention as far as the TT goes, but that's just for show. The more tangible news from Audi's stylish sports car range at the
this year is the Roadster.
Like its predecessors, the new Audi TT Roadster ditches the coupe's fixed roof and rear seats in favor of an open two-seat cockpit with a traditional folding fabric enclosure that's quieter and lighter than the previous TT's mechanism.

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.
