Will the speed decrease when releasing the accelerator pedal?

[McKira]

For automatic transmission vehicles, when the speed reaches a certain level, releasing the accelerator pedal will cause the speed to drop rapidly. If the accelerator pedal is not pressed again, the vehicle will eventually come to a stop, as all vehicles rely on fuel to maintain normal operation. However, some high-end automatic transmission vehicles are equipped with a "cruise control" function, which is exclusive to automatic transmission cars. In such vehicles, when the speed reaches a certain level and the accelerator pedal is released, the vehicle will continue to travel at the preset speed. Here is more information: Automatic transmission cars: They usually use hydraulic transmission devices to replace the mechanical clutch of manual transmission cars, so there is no clutch pedal. When the engine speed is low, the torque transmitted by the fluid is limited and insufficient to propel the car forward. When the gear lever is placed in the drive position and the brake pedal is released, as the accelerator is pressed and the engine speed increases, the transmitted torque increases, pushing the car forward. If driving a manual transmission car: Compared to skilled drivers operating manual transmission cars, under the same driving conditions, automatic transmission cars generally consume about 6~10% more fuel. Automatic transmission cars have higher fuel consumption than their manual transmission counterparts of the same model, approximately 1 liter more per 100 kilometers. In terms of vehicle cost, the cost of an automatic transmission is higher than that of a manual transmission for the same model. The advantage of automatic transmission over manual transmission lies in its ease of driving.
