Audi is looking to replace gasoline as the top fuel source for cars with a synthetic, environmentally-friendly alternative that doesn't need petroleum.

This new fuel, called "e-benzin," requires no petroleum in its production, which gives it the ability to burn in a much cleaner way, according to Digital Trends. The German automaker said that engines can also use higher compression ratios for extra frequency since the fuel doesn't include sulfur or benzene.

E-benzin was developed thanks to Audi's partnerships with Global Bioenergies, which provided isobutene from renewable materials as the basis for the fuel, and the Fruanhofer Center for Chemical-Biotechnological Processes, which uses oxygen to purify the isobutene.

Audi plans to test the new gasoline to see how well it performs in its cars, Digital Trends reported. The end-goal is for the fuel to only need water, hydrogen, carbon dioxide (CO2) and sunlight to keep cars going.

E-benzin is Audi's latest project aimed at providing cleaner fuel sources for cars, as the company previously developed "e-gas," which was produced with wind energy, and "e-diesel," which was made from water and electricity.
