More passengers and cargo increase overall weight, leading to higher fuel consumption.
Fully loaded, the Prius may lose 2-4 MPG compared to driving with just the driver.
To maintain efficiency, owners should:

Reduce unnecessary weight empty trunk when not needed.
Keep tire pressure optimized for better rolling resistance.
