What does 'car is sluggish' mean?

[Mildred]

'Car is sluggish' refers to a vehicle having insufficient power and experiencing lag in acceleration. Factors that determine whether a car is sluggish include: Key engine parameters: Mainly power and torque. Power per liter refers to the utilization rate of the unit cylinder working volume. When the engine power is constant, the higher the power per liter, the higher the engine's utilization rate, which translates to better acceleration and lower fuel consumption. Torque represents the car's instantaneous acceleration capability. The greater the torque, the stronger the instantaneous acceleration ability. For vehicles with the same displacement and body weight, those with higher torque accelerate faster, while those with lower torque feel more sluggish. Body weight: The weight of the car directly affects whether it feels sluggish. Under the same conditions of power per liter, torque, and displacement, heavier cars have relatively slower starting speeds and feel more sluggish to drive. Lighter cars start faster.
