What does turbo in a car mean?

Turbo in a car refers to a turbocharger, which is a device that increases an engine's efficiency and power output by forcing more air into the combustion chamber. It utilizes exhaust gases to spin a turbine, which then compresses incoming air, allowing for a greater amount of fuel to be burned. This results in improved performance and acceleration without significantly increasing engine size. Turbocharged engines are often more fuel-efficient than naturally aspirated engines of similar power.
