1 Answers
2.5s indicates a 2.5-liter engine displacement. Here, 2.5 represents the displacement, while S denotes the series number of this vehicle model. Classification of automobile engine displacement: In China, passenger vehicle classifications are determined by engine displacement. Mini cars have displacements ≤1.0L; compact cars range between 1.0-1.6L; midsize cars fall within 1.6-2.5L; executive cars cover 2.5-4.0L; and luxury cars exceed 4.0L. Significance of engine displacement: Displacement is typically measured in liters (L). As one of the most crucial structural parameters, engine displacement more accurately represents an engine's size than cylinder bore or count. Numerous engine performance metrics are directly correlated with displacement.
