Does stepping on the gas to reach 4000 RPM in an automatic transmission damage the car?

Stepping on the gas to reach 4000 RPM in an automatic transmission does damage the car. When starting the car, you should not abruptly increase the engine speed to a very high level. During startup, the engine speed should be maintained between 2000 and 3000 RPM. After the car has smoothly started, you can then increase the engine speed, which minimizes the instantaneous impact on the engine and helps protect it. Here are some additional details: 1. High RPM: Running the engine at high RPM has certain benefits for the car, but it is not recommended to drive at high RPM for extended periods. High RPM allows the gasoline in the engine to burn more completely, which not only enhances the engine's power but also helps prevent carbon buildup in the engine. This is why the car runs more smoothly after high-speed driving. Under normal idle conditions, the engine speed is around 800 RPM, as the engine does not generate much power in this state. 2. Economical RPM: During operation, maintaining the engine speed between 1500 and 2000 RPM is the most fuel-efficient, as this is the engine's economical RPM range. This ensures both sufficient power and optimal fuel consumption, thereby extending the engine's lifespan to some extent.
