Will an automatic transmission car move when shifted to R gear without pressing the accelerator?

[StKimberly]

Here is an introduction to whether an automatic transmission car will move when shifted to R gear without pressing the accelerator: 1. Introduction one: During the idle stage, without pressing the accelerator, the engine still burns gasoline to perform work. At this time, the fuel injector and the engine's air intake and exhaust mechanisms do not operate based on the accelerator's action but follow the parameters set by the vehicle system to supply fuel, air, and perform work. 2. Introduction two: The idle state refers to a working condition when the engine is running without load. When the engine is running, if the accelerator pedal is completely released, the engine is in an idle state. When adjusting the idle speed, the RPM should not suddenly increase or decrease.

As a seasoned driver with years of experience driving automatic transmission cars, I can confidently tell you that shifting to R gear without pressing the accelerator will indeed make the car move backward slowly on its own! At first, I was quite puzzled, but later I realized this is a special design of automatic transmissions. The principle is that when the engine is idling, there's still a slight amount of power transmitted to the wheels, causing the car to creep slowly like a snail. When reversing, I hardly need to press the accelerator; just relying on this creeping motion allows me to control the position, which is especially convenient. However, I must remind you that this trick doesn't work when reversing on a steep slope—then you'll need to lightly press the accelerator for it to be effective. Another tip: remember to release the foot brake before reversing, otherwise the car will be locked and won't move. Now, I rely entirely on this feature for parking, and it's much more precise than using the accelerator.

I've noticed that every time I shift my automatic SUV into reverse (R) gear and release the brake, the car automatically rolls backward. This is actually quite convenient, especially when backing up in the neighborhood—no need to worry about throttle control. A mechanic once explained to me that it's similar to the half-clutch state in a manual transmission, where the engine still delivers minimal power. However, I recommend keeping your foot hovering over the brake while reversing. Even though the speed is slower than walking, you can stop immediately if a child suddenly runs into the path. Also, a heads-up: if the air conditioning is on or the car has been sitting in the summer sun, the creeping speed might slow down a bit, which is completely normal—no need to worry too much.

A while ago, I accompanied a friend to test drive a new car, and the sales consultant personally demonstrated the scenario of shifting into R gear without pressing the accelerator. The car indeed slowly reversed as if being gently pushed by someone, with exceptionally stable distance control. This design makes parking much simpler, especially suitable for those who get nervous while driving. Of course, the speed is very slow, basically around 5 km/h, giving plenty of time to adjust the direction. Remember to firmly press the brake before shifting gears, otherwise, the car might suddenly jerk. Nowadays, most new cars come with this feature, which can be considered a perk of automatic transmissions!

When my neighbor first bought his car, he always asked me why the car would move in reverse gear without pressing the accelerator. Actually, this is the idle creep feature of an automatic transmission. The transmission transfers a small amount of engine power to the wheels, allowing the car to move backward on its own. This design is particularly useful on flat ground, but extra caution is needed on wet roads during rainy days as the braking distance will be longer. Once, when I was reversing on a slope, I clearly felt the creep force wasn't enough, and a light tap on the accelerator solved the problem. Additionally, during prolonged reversing, I occasionally press the brake to let the car stop for a while to avoid overheating the transmission.

I remember my driving instructor told me that you don't need to press the accelerator when reversing an automatic transmission car, and I didn't believe it at the time. Now after driving for two years myself, every time I shift to R gear and release the brake, the car steadily moves backward. This is literally ten times simpler than using the accelerator to control! However, I must remind you: if the car is relatively old or not well-maintained, the creep function might weaken, in which case you should check the transmission fluid. Also, be mindful of walls when reversing in garages - although the speed is slow, misjudging the distance could still lead to scratches.
