Will an automatic transmission car move when shifting gears without stepping on the accelerator?

An automatic transmission car will move forward when shifting gears without stepping on the accelerator. The specific situations are as follows: 1. The D gear is the forward gear. It is the most common gear in automatic transmission models, usually located in the middle and rear position of the gear shift console, behind the N gear, designed to automatically select gears when the car is moving forward. 2. If driving the car on an upward slope, without stepping on the brake, and the slope angle is large, even if the car's gear is shifted to D, the car may not move forward, stay in place, or even roll backward. 3. If on a downhill section, without stepping on the brake, the car will definitely move forward. 4. If you need to stop and wait, it is best to shift the car's gear to P.

I've been driving automatic transmission cars for over ten years, and it's true that the car will move slowly when in D gear without pressing the accelerator. This happens because the engine outputs a small amount of power at idle, which is transmitted to the wheels through the automatic transmission, allowing the car to creep forward slowly on flat ground. This feature is particularly useful when maneuvering in parking lots or during traffic jams, as it eliminates the need to constantly press the accelerator. However, be cautious—if you're on a slope without pressing the brake, the car might roll backward, posing a danger. It's good to practice controlling the speed to ensure safety.

From the perspective of automotive working principles, the output torque at engine idle allows vehicles with automatic transmissions to creep forward without pressing the accelerator. This design facilitates low-speed maneuvering, such as saving effort in residential areas or congested road sections. However, performance varies across different models: small-displacement cars may move slower, while SUVs or high-power vehicles exhibit more noticeable creeping. It's important not to overly rely on this feature, especially on slopes where loss of control is more likely, and to keep the brake ready as a precaution.

As a new driver, I often get confused: Can the car really move when in D gear without pressing the accelerator? Yes, it will move very slowly, but don't let your guard down. This is manageable on flat ground, but relying too much on it in parking lots or on slopes could lead to loss of control. Always keep your speed within a controllable range, safety first. Engine idle driving is indeed convenient, but don't overlook the potential risks.
