What is the difference between displacement with and without a T

[Prim]

A T indicates that the car's engine is equipped with a turbocharged engine. Compared to those without a T, these engines have smaller displacement but more power. The T at the back of a car refers to a Turbo-Boost engine. The main function of a turbocharger is to increase the engine's air intake, thereby enhancing the engine's power and torque, making the vehicle more powerful. Cars without a T mean they do not have a turbocharger and are naturally aspirated engines. More details are as follows: 1. Cars with turbocharged engines feature smaller engine displacement and stronger power, with little difference in fuel consumption between the two types of engines. 2. Emissions, especially carbon dioxide, can also be reduced, which helps better protect the environment. However, turbocharged engines have a limited lifespan and higher maintenance costs.
