MYTH #1 - Hybrids only run on a special grade or octane of gasoline. False! The entire Toyota Hybrid Models lineup runs on regular-grade unleaded gas. Since these engines operate on an 87-octane fuel rating, putting in higher-grade gasoline will not improve fuel economy estimates, nor provide additional power.Sep 4, 2019
It Begins with Hybrid Technology In a nutshell, this system allows the Prius to capture some of the energy that is normally dissipated into the air while driving, and reuse it. One way the Prius reuses energy is by capturing energy from braking and using it to charge the vehicle's hybrid battery.
The Toyota Prius is a parallel hybrid; this means it has a gasoline engine and electric motor that are separate from one another. Further, each can run on its own. Toyota designed the Prius so that it would utilize electric power (which it stores in the battery) instead of gasoline power whenever possible.
