What are the effects of pressing the accelerator in P gear on the car?
2 Answers
Pressing the accelerator in P gear has the following effects on the car: 1. When the car is stationary and the accelerator is pressed in P gear, it basically has no significant impact on the vehicle. In P gear, the transmission's drive shaft is locked, and the engine is separated from the transmission. The power is not transmitted to the drive shaft; the engine merely consumes fuel without load, and the gear mechanism idles, so the car does not move. 2. If the accelerator is pressed in P gear while the car is moving, this is incorrect. The parking lock will engage the wheel groove, and if the car is in motion, this action can cause the parking lock to break. In severe cases, it can lead to significant damage to the transmission, potentially requiring a replacement.
I've driven many cars before and also tried stepping on the accelerator in P gear, which was just me playing around out of boredom while waiting in a parking lot. The car only roared loudly without moving. Later, a friend from the car factory explained that this would cause the engine to continuously idle at high speed, increasing internal wear. Especially for automatic transmission cars, the transmission's locking device has to bear additional load, and prolonged operation might lead to overheating and component damage. Next time before stepping on the accelerator, make sure the gear is in the correct position to protect the vehicle's health.
