What does 1.8t mean in cars?

[Finn]

1.8t in cars refers to the engine displacement, where a larger displacement generally means stronger power. The 't' after the number indicates a turbocharged model, while models without 't' are naturally aspirated. In China, car classifications are determined based on engine displacement, categorized as follows: 1. Mini cars with displacement ≤1.0L; 2. Compact cars with displacement between 1.0L and 1.6L; 3. Mid-size cars with displacement between 1.6L and 2.5L; 4. Executive cars with displacement between 2.5L and 4.0L; 5. Luxury cars with displacement >4.0L.
