Audi announced the launch of a new gas-powered version of the A3 Sportback in Germany. The A3 g-tron can be powered by ultra-clean Audi e-gas produced using green electricity, or by compressed natural gas, both of which are cheaper and cleaner than petrol.

Whatever sort of gas you put in it, the 1.4-litre TFSI engine develops 110 PS which delivers decent performance on the par with that of the petrol-powered models. What gives it an advantage over the petrol model is the running cost. Audi A3 g-tron consumes between 3.2 and 3.3 kilograms of gas per 100 kilometers, meaning it costs only 3.50 euros per 100 kilometres to drive this car at present gas prices.

Audi recommends their own e-gas for this car, which they say is better because it is produced using green electricity in the world’s first industrial power-to-gas plant in Lower Saxony, Germany. They have even issued Audi e-gas fuel card for a flat price of 14.95 euros per month which can be used to purchase cheaper gas form the 650 fuel stations in Germany.

Audi A3 g-tron is currently only offered in Germany where it starts from 25,900 Euros.
