Audi is designing the mobility of the future in which environmentally friendly produced electricity plays a key role. It not only powers the electric motors in the e-tron models, it is also the powerhouse behind certain Audi e‑fuels: climate-friendly alternative fuels for combustion engines. Audi produces fuels that do not depend on petroleum, that bind as much CO₂ during their production as they emit during combustion. They are known as Audi e‑gas, Audi e‑diesel, Audi e‑gasoline and Audi e‑ethanol. With Audi e‑gas, Audi already offers A3 g-tron* customers climate-neutral mobility.
