    Every vehicle engine, or motor, regardless of fuel type (Hybrid, Gasoline, Propane, Hydrogen, Electric, ect) has an expected operational range.

    For this conversation, we won't go into the differences between an engine as compared to a motor. That will need it's own post. We will just use the generic term: engine.

    Operational range is the way in which the engine is going to be used and operational characteristics are designed into the engine for that anticipated use. Since not all will used the same way, the engines operating range is conditioned for its application.

    I.E.: compare the engine needs for a small convertible sports car (light weight and responsive) to the needs of a semi truck (heavy loads and extended run time).
    It's not fair to compare apples to oranges. But to compare similar vehicles, you still have to analyze how it will be driven and make your decisions based on that.
