Pros and cons of automatic transmission ECO mode: The biggest advantage of enabling ECO mode in a car is improved fuel efficiency, which reduces operating costs. The downside is that the vehicle may experience slightly reduced power output. Additionally, if the engine frequently operates at low speeds, fuel combustion may become insufficient, leading to increased carbon deposits in the engine. ECO stands for the initials of three English words: Ecology, Conservation, and Optimization. It is a vehicle energy-saving mode that achieves fuel efficiency when activated. Working principle of ECO: ECO primarily makes comprehensive judgments and analyses of various factors affecting fuel consumption during vehicle movement, including automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit then calculates the optimal fuel quantity to supply the engine, effectively reducing fuel consumption compared to normal driving modes. Simply put, it controls engine RPM through appropriate gear selection to minimize unnecessary fuel consumption.
