Can the Fuel-saving Mode Be Kept On for a Long Time?

Most vehicles adopt an active eco-driving mode, which means they have a dedicated switch button. Therefore, the eco mode can be activated during daily driving. However, it is unnecessary to enable the eco mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not reflect the fuel-saving characteristics of the eco mode and could also impact the vehicle's power performance. Other driving modes available in cars include: 1. Economy Mode: This mode effectively reduces engine fuel consumption and emissions through advanced shifting programs and optimized operation, making it a highly energy-efficient and environmentally friendly driving mode. 2. Comfort Mode: The transmission shifts gears at lower engine speeds, saving both effort and fuel. 3. Sport Mode: Suitable for driving on winding roads, this mode delays gear shifts until higher engine speeds, providing highly responsive throttle input, rapid acceleration, and powerful performance.
As an automotive engineer, I understand many people want to save fuel, so here's the direct conclusion: Long-term use of ECO mode is fine, especially when stuck in city traffic—it won't harm the car. This function simply makes the transmission shift gears earlier, dulls throttle response, and slightly moderates the air conditioning, naturally saving some fuel. However, you'll need to accept the experience of pressing the accelerator like stepping on cotton. On highways, I recommend turning it off for more responsiveness. The key is not to stomp on the gas for sudden acceleration while using this mode, as it can offset the fuel-saving effect. Avoid forcing ECO mode during the break-in period of a new car or on mountainous roads with frequent climbs—turn it off when overtaking is necessary.
