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

- CO2-neutral mobility with the Audi e-gas fuel card

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. This is because the process for generating Audi e-gas using green electricity binds as much CO2 as is released when the Audi A3 g-tron is driven in gas mode. On average the Audi A3 g-tron consumes between 3.2 and 3.3 kilograms of gas per 100 kilometers. Fuel costs at present start at around 3.50 euros per 100 kilometers.
The buying principle for Audi e-gas is straightforward and corresponds to how green electricity is distributed: Audi records the quantities of gas that the customer pays for using their Audi e-gas fuel card and ensures that exactly this amount of Audi e-gas is fed into the German natural gas network.
Customers who choose this option can obtain an Audi e-gas fuel card for a flat price of 14.95 euros per month. In addition, the costs for the quantities of gas refueled by each customer are deducted via the Audi e-gas fuel card. The card can be used to purchase Audi e-gas at over 650 fuel stations in Germany.
Prof. Dr. Ulrich Hackenberg, Board Member for Technical Development at AUDI AG, emphasizes: "In addition to our e-mobility developments, the Audi e-gas project is an important pillar of our sustainability strategy – as is the development of other synthetic fuels." Audi is already operating a research facility for the production of Audi e-ethanol and e-diesel with its partner Joule in Hobbs, New Mexico. Moreover, the company is conducting research into the synthetic manufacture of Audi e-gasoline in cooperation with Global Bioenergies.
