Will the speed decrease when releasing the accelerator?

[ArianaFitz]

Releasing the accelerator will cause the speed to decrease rapidly. Here are the relevant details: 1. 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. 2. Manual transmission cars: Compared to skilled drivers of 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 manual transmission cars of the same model, approximately 1 liter more per 100 kilometers.
