The passenger compartment is the area inside a vehicle where passengers sit. It is designed for comfort and safety, typically featuring seats, seatbelts, and controls for climate and entertainment. This space is separate from the engine compartment and cargo area, ensuring a more pleasant experience for those traveling in the vehicle. In cars, the passenger compartment often includes features like air conditioning, infotainment systems, and cup holders. The layout can vary significantly between different types of vehicles, such as sedans, SUVs, and vans, each designed to accommodate varying numbers of passengers and their needs.
