Passenger car
A motor vehicle designed primarily to carry people on roads, typically with seating for a small number of occupants and space for their belongings.
Internal combustion engine: An engine that generates power by burning fuel inside its cylinders or combustion chambers. It converts fuel energy into motion in many passenger cars.
Motor vehicle: A vehicle propelled by an engine or motor rather than by human or animal power. Passenger cars belong to this broader class of road vehicles.
Automotive safety: The design, regulation, and operation of vehicles to reduce collisions and their harm. Safety engineering governs the car’s structure, restraints, and driver assistance.
Truck: A motor vehicle designed primarily to transport cargo rather than passengers. Its main purpose differs from a passenger car’s passenger-carrying role.
Electric vehicle: A vehicle propelled partly or entirely by electric motors powered by stored electrical energy. Battery-powered models replace the conventional engine and fuel system.
Automobile layout: The arrangement of a vehicle’s engine, driven wheels, and passenger or cargo space. Layout shapes cabin space, handling, and the packaging of a passenger car.
Fuel economy in automobiles: A measure of how far a vehicle travels using a given amount of fuel or energy. It affects a car’s running cost and energy use.
Bus: A road vehicle designed to carry many passengers, usually along a shared route. Buses serve higher-capacity passenger transport than private cars.
Transmission (mechanics): A mechanism that transfers power from an engine or motor to a vehicle’s wheels. It matches the power source’s speed and torque to driving conditions.
Sedan (automobile): A passenger car with a separate trunk and a fixed roof, typically organized into three compartments. It is a common passenger-car body style.
