While hybrid cars share some common features, such as an internal combustion engine and an electric motor, there are different types of hybrid vehicles that operate on different principles.
For instance, some hybrids use a parallel hybrid system, where the electric motor and the gasoline engine can power the wheels simultaneously or independently, while others use a series hybrid system, where the electric motor is the sole source of power for the wheels and the gasoline engine is used to generate electricity.
Additionally, there are plug-in hybrid electric vehicles (PHEVs) that can be plugged in to charge their batteries, allowing them to travel longer distances on electric power alone compared to conventional hybrids.
