Tiberium Fuel is an upgrade available at the Tech Lab.
Tiberium Essence[]
As the Enhanced Avionics upgrade was removed after the version 1.4, allowing Banshees to attack air units by default. It was replaced by the Tiberium Fuel upgrade, which allows the Banshees to activate supersonic boosters in order to travel at much faster speed for a few seconds. While using the ability, the Banshees are unable to attack. It is best used after the Banshee has already attacked an enemy unit or structure and needs to return to the Air Tower, as it often allows the Banshee to retreat without being hit by anti-air fire.
Trivia[]
During the development of version 1.5, the upgrade was referred to as Afterburner.
