What does a 1.6L displacement car mean?

[SanReed]

1.6L displacement means the car has an engine displacement of 1.6 liters. The space volume that the engine piston moves from top dead center to bottom dead center is called cylinder displacement. If an engine has multiple cylinders, the sum of all cylinders' working volumes is called engine displacement, usually expressed in liters (L). 1.6L means the car's engine displacement is 1.6 liters. There are also 1.8L, 2.0L, and 2.4L engines. The larger the displacement, the more fuel the engine burns in the same amount of time, generating more thermal energy. When this thermal energy is converted into the car's kinetic energy, the car becomes more powerful. Generally, cars with 1.6L or smaller displacements are intermediate sedans or compact cars, while SUVs, sports cars, and premium sedans usually have larger displacements.
