In a busy city, there is a phenomenon where a friend's car of mine occasionally "dances" when idling, and the engine shakes as if it is a mechanical breakdance. Initially, it is diagnosed that this may be caused by excessive carbon deposits. So, he decided to take his car to the repair shop to clean it up. While waving the wrench, the car repairer also gave a "driving cheats" - try not to use ECO mode when driving in urban areas, how do you say this?
The core concept of ECO mode, the guardian of fuel economy, is to make the car as energy-efficient and emission-reducing as possible while driving by controlling speed and fuel consumption reasonably. Theoretically, the larger the displacement of the engine, the more significant the fuel savings in ECO mode. For example, those who have 2The abundant power of the car with a large heart of more than 5L provides more room for the ECO mode to play, and the fuel-saving effect is obvious. However, for those with a displacement of 2For 0L or even lower small-displacement models, the performance of ECO mode is slightly embarrassing.
However, there is no absolute good or bad in this world, just like some people like bitter coffee, and some people prefer sweet and greasy. In the case of urban congestion or stop-and-go situations, ECO mode sacrifices some acceleration performance in exchange for a smoother and more comfortable driving experience, which is acceptable for many car owners. After all, most of the power output of the vehicle in a traffic jam is like a dumbbell in a gym, and there is nowhere to show it when it looks like a powerful man.
But if you're a fast-paced teenager, the ECO model might feel like a snail shell to a race car. It's always upshifting early and slowing down the revs, making it feel like you're racing in slow motion, which will undoubtedly be a bit of a disappointment for those who are keen on driving in sports. And, technically, frequent early upshifts in ECO mode can lead to the engine often running at low revs, and over time, the problem of insufficient fuel combustion comes to the fore, especially for direct-injection engines.
For example, in normal mode, your car will happily jump from second to third gear at 1,800 rpm at the start, while in ECO mode, the transmission will rush to upshift at 1,600 rpm, which is relatively low. Running in the low-rev range for a long time after upshifting is like letting the engine do low-intensity workouts for a long time, which can easily cause health problems such as carbon deposits.
Therefore, although ECO mode can indeed play a role in saving energy in certain scenarios, for long-term vehicles, it may be better to switch to sport mode at the right time, increase the rpm, and let the engine enjoy the smooth high-speed operation.
All in all, whether the ECO mode is really right for you is as much a matter of road conditions and personal needs as the choice between running shoes and hiking boots. Dear readers, do you usually choose to use ECO mode when driving? Do you think this model is a real fuel-saving artifact, or does it invisibly kill the fun of driving?
