What is the displacement of a car?

[VonRachel]

Car displacement refers to the size of the engine, usually measured in terms of displacement or exhaust volume. Displacement refers to the volume of fluid inhaled or discharged per stroke or cycle. Car displacement is an important structural parameter for measuring a car, and it represents the size of the engine more accurately than bore diameter and the number of cylinders. Many indicators of the engine are closely related to the exhaust volume. The classification of cars is based on the displacement size: cars with a displacement of 1.0L or less are classified as micro cars; those with a displacement between 1.0L and 1.6L are considered compact cars; those with a displacement between 1.6L and 2.5L are mid-size cars; those with a displacement between 2.5L and 4.0L are full-size cars; and luxury cars have a displacement greater than 4.0L.
