Does Low Gear with High RPM Damage the Car?

[BenjaminRose]

Low gear with high RPM can damage the car. Below are the relevant explanations: 1. Hazards of low gear high-speed driving: Driving at low gear with high speed means operating under an inappropriate transmission ratio, which can easily cause engine vibration. At this time, the reciprocating motion of the pistons and the rotation of the crankshaft connecting rods are subjected to excessive force, leading to severe wear and premature engine damage. Additionally, the clutch also bears significant load, causing the clutch plate to wear out prematurely. 2. Relationship between engine torque and gear selection: There is a common misconception in driving that can cause significant damage to the engine, which is upshifting to overtake. In fact, when in a higher gear, the engine torque is relatively smaller, and the throttle response is less sensitive, making it difficult to achieve the desired acceleration effect.
