Notwithstanding its success with cult TFSI and TDI engines, Audi is progressively relying on non-standard drive systems such as the g-tron models that operate with natural gas or compressed natural gas (CNG). Another area of focus for the company has been the synthetically produced, climate-neutral Audi e-gas.

The purpose of the increased focus on these forms of CO2-neutral mobility is simple: environment-friendly performance. In fact, Audi has already achieved the goal of virtually carbon-neutral driving by the means of the Audi e-gas. The fuel, processed from water and carbon dioxide with green electricity or from recyclable materials such as straw and green waste, does not require mineral oil. Furthermore, it emits only as much CO₂ in the exhaust as it absorbs during its manufacture.

And to enable to its adoption, the company offers e-gas for three years as a standard feature to customers who order an Audi g-tron model by 31 May, 2018. Audi secures the environment-friendly benefits of the initiative, including a decrease in CO2 emissions, by supplying the measured volume of e-gas into the natural gas grid.

Besides this technological masterpiece, Audi also has its sight set on other forms of renewable fuels. Take Audi e-fuels for example; the production of these synthetic fuels, which includes e-diesel, e-benzin (e-gasoline), and e-ethanol, absorbs the quantity of CO2 emitted by the car while it is being used. This means the carbon dioxide is recycled.
