The acceleration obtained from stepping on the gas pedal forcefully may result in some idling conditions because of the inertia, which cancels out a lot of power, making it less cost-effective. Moreover, aggressive driving exacerbates tire wear. When releasing the gas pedal, the car's engine will experience a sudden and significant reduction in speed, repeatedly pulling back the car's inertial motion. This is equivalent to shifting to a lower gear with a higher deceleration ratio than in neutral, turning traction into resistance.
If it's a deep and forceful press on the gas pedal, not only does it feel like a strong jerking sensation during acceleration, but it can also cause the engine to overheat, leading to radiator boiling and other engine malfunctions. Therefore, it is not recommended for everyday driving. However, if you need to overtake quickly, that's a different story.
Rapid acceleration in automatic transmission is equivalent to all-round damage to the car. It intensifies abnormal wear on tires and brake pads. Forcefully stepping on the gas pedal can cause the air-fuel mixture to be too rich, resulting in a certain air-fuel ratio error. This can lead to incomplete combustion in the carburetor and the generation of a large amount of carbon deposits. Over time, some of the carbon deposits will be expelled with the exhaust, but others will adhere to the internal surface of the three-way catalytic converter and the oxygen sensor, gradually causing blockage in the catalytic converter and sensor failure.
Furthermore, habitually stepping on the gas pedal deeply will obviously cause the engine speed to be too high when the engine is cold, resulting in serious wear and tear on the engine. Long-term high-speed operation will cause more severe cylinder wear than normal driving. Also, deep gas pedal use during turns and frequent abrupt braking can affect the chassis suspension.
