What is the difference between with T and without T?

[AllieAnn]

There are the following differences between with T and without T: 1. With T: A car with T refers to the engine using turbocharging, where T stands for "TurboBoost", meaning turbocharging. Turbocharging utilizes the high-speed exhaust gas from the engine to drive the turbine, increasing the intake pressure, thereby increasing the intake air volume, making the fuel-air mixture burn more completely, and significantly improving the engine's power and torque, achieving exhaust gas reuse. 2. Without T: Without T means the car uses a naturally aspirated engine. A naturally aspirated engine only uses the negative pressure formed by the piston's downward movement to draw air into the cylinder and combustion chamber, while the exhaust gas is directly discharged without reuse. For engines of the same displacement, the naturally aspirated engine has a smaller intake air volume, and its power and torque are also lower.
