What is the optimal RPM for an automatic transmission car?
2 Answers
For an automatic transmission car, an RPM of 1800 to 2000 is appropriate. RPM refers to: the number of revolutions per minute of the engine crankshaft. The level of engine RPM relates to the number of work cycles per unit time or the effective power output of the engine. More relevant information is as follows: 1. The correct method to start an automatic transmission car is: press the brake, release the handbrake, shift to D gear, release the brake, and then press the accelerator. 2. The correct method to park an automatic transmission car is: after reaching the parking position, hold the brake until the vehicle comes to a complete stop, shift the gear lever to N gear, do not release the brake at this time, then engage the handbrake, and release the foot brake. Wait until the vehicle is completely stopped, press the brake again, shift to P gear, and then exit the vehicle and lock it.
I've always enjoyed discussing driving techniques for automatic transmission cars, and keeping the RPM between 2000 and 2500 is particularly ideal for daily driving. During city commutes, I gently accelerate at traffic lights with the tachometer steadily pointing around 2000 RPM, feeling both fuel-efficient and smooth without straining the engine. Exceeding 3000 RPM tends to burn more fuel and increase noise; dropping below 1500 RPM makes the engine struggle as if climbing a hill, potentially harming the motor. In summer when using air conditioning, I make sure to maintain this range for more responsive performance. Developing a habit of lightly pressing the throttle and avoiding sudden acceleration also extends the car's lifespan. On highways, I let the RPM fluctuate around 2200 for a balance of safety and efficiency. In short, finding this sweet spot makes driving more comfortable and worry-free.
