The ESP system has a negligible impact on fuel efficiency; its core function is to ensure driving safety by real-time monitoring of vehicle dynamics and intervening to adjust braking force or engine output when necessary. The system is only briefly activated under extreme conditions, with its power consumption typically below 50 watts-equivalent to the energy consumption of a car radio-and its potential impact on combined fuel consumption is less than 0.1L/100km, far lower than the energy consumption of conventional equipment such as air conditioners. While deactivating ESP may eliminate momentary jerks caused by system misjudgment, this subjective improvement in driving experience bears no direct relation to fuel savings; instead, it forfeits 70% of anti-skid protection capability on slippery surfaces or during emergency manoeuvres. Genuinely effective fuel-saving measures should prioritize quantifiable factors like maintaining proper tyre pressure, cultivating smooth driving habits, and performing regular maintenance, which can yield fuel efficiency gains of 0.3-1.5L/100km. Professional recommendations advise temporarily disabling ESP solely for specific scenarios like sand recovery or track drifting; it should remain active during routine driving to ensure safety, as compromising critical safety systems for marginal theoretical fuel savings proves counterproductive.
