A car is a wheeled motor vehicle used for transportation, typically designed to run primarily on roads and accommodate one to eight people. It usually has four wheels and is powered by an internal combustion engine or an electric motor. Modern cars come equipped with a variety of features for comfort, safety, and performance, such as air conditioning, advanced infotainment systems, airbags, and driver-assistance technologies. Cars vary widely in size, style, and function — from compact city vehicles to large SUVs and luxury sedans. Beyond being a practical mode of transport, cars also represent freedom, status, and personal taste for many people around the world.
