6. Types of HEVs:

• Parallel Hybrid: Both the gasoline engine and the electric motor can directly power the vehicle, with power flowing from both sources to the transmission.
• Series Hybrid: The gasoline engine powers a generator, which charges the battery or directly powers the electric motor. The motor then propels the vehicle.

7. Advantages:

• Improved fuel efficiency and reduced emissions compared to traditional internal combustion engine vehicles.
• Regenerative braking contributes to energy conservation.
• Flexibility to operate in electric mode at lower speeds, reducing noise and emissions in urban settings.

8. Considerations:
