The Audi A3 Sportback g-tron* stands for sustainable mobility of the future: The five-door premium compact model can use climate-friendly Audi e-gas as an alternative to fossil natural gas. The two tanks located under the luggage compartment floor each store around 7 kilograms (15.4 lb) of gas at a maximum pressure of 200 bar. They reduce luggage space only marginally and are constructed from a composite material, making them very light.
Equipped with a 1.4 TFSI engine producing 81 kW (110 hp), the Audi A3 Sportback g-tron sets standards for efficiency and economy. Fuel costs to the customer are roughly four euros per 100 kilometers (62.1 mi). Thanks to the four-cylinder engine’s configuration for bivalent fuels, its range is over 400 km (248.5 mi) in the NEDC cycle with natural gas fuel. When powered by gasoline, the driving range is extended by an additional 900 km (559.2 mi). Switching from one operating mode to the other happens automatically without the driver having to intervene. The instrument cluster separately displays the residual ranges in both modes.
The Audi A3 Sportback g-tron is equipped with a six-speed manual transmission or a seven-speed S tronic off the production line. With S tronic it consumes only 3.3 kilograms (7.3 lb) of natural gas or Audi e-gas per 100 kilometers (62.1 mi) in the NEDC cycle, corresponding to an emission of 89 grams of CO2 per kilometer (143.2 g/mi). Audi e-gas is a sustainable fuel produced by the brand with the four rings in the world’s largest power-to-gas plant in Werlte, in Germany’s Emsland region. The synthetic methane is produced here with the aid of green electricity from CO2 and water. In operating with e-gas, the five-door premium compact is practically CO2 neutral. Customers can refuel using an e-gas card, which also serves as an accounting tool.
The power-to-gas technology stores wind and solar energy in large amounts, bringing forward the energy revolution. Audi e-gas and the A3 Sportback g-tron thus offer a particularly environmentally friendly form of long-distance mobility. The manufacture of Audi e-gas utilizes just as much CO2 as is released when the Audi A3 Sportback g-tron is driven with CNG.
The reference principle is simple and corresponds to the distribution of green electricity: Audi registers the amounts of gas, which the customer pays with the fuel card, and ensures that exactly this amount of Audi e-gas is fed into the German natural gas grid. The Audi A3 Sportback g-tron costs 26,950 euros in Germany.
