Is it necessary to turn off the auto start-stop function in the BMW X1?

It is not necessary to turn off the auto start-stop function in the BMW X1. The auto start-stop feature is a practical fuel-saving configuration, especially on roads with frequent traffic lights. The auto start-stop system can automatically control the engine shutdown and ignition, known as STOP&START, or STT for short. Vehicles equipped with engine auto start-stop technology will automatically shut off the engine when temporarily stopping during driving. When it's time to move forward again, the system will automatically restart the engine. How the auto start-stop system works: When the vehicle stops due to congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine automatically stops running. Pros and cons of the auto start-stop system: The advantage is fuel efficiency; whether waiting at a red light or in traffic, the engine auto start-stop technology can automatically turn off the engine when stopped to save fuel. The downside is increased vehicle costs; cars with auto start-stop systems are more expensive than those without. Additionally, due to the frequent repeated starts and stops of the engine, there is a higher demand for oil quality, leading to further increases in maintenance costs.
As a BMW X1 owner who has been driving in the city for a year, I find the auto start-stop function quite practical. It automatically shuts off the engine at red lights, saving some fuel costs. However, the frequent restarts can be annoying, especially in congested areas. There's a slight vibration each time the engine restarts, which might affect comfort over time. To be honest, if you often take short trips, like in residential traffic jams, or if the battery condition isn't great, turning it off might be more pleasant. This feature is designed for environmental protection and fuel economy, but BMW's system will pause the start-stop in cold weather or when the air conditioning is turned up high, as an automatic protection measure. I suggest adjusting it based on your habits. If you commute a lot in the city, try turning it off for a few days to see the difference. It doesn't have a major impact on overall driving, and the X1 has a default button for easy operation anyway.
I've been driving for over a decade, including BMW models. The auto start-stop system is well-designed on the X1, theoretically saving fuel and reducing idle emissions. However, in practical use, I've noticed that frequent starts and stops can slightly accelerate battery and starter wear, especially if you drive in heavy traffic. In the long run, the fuel savings might not cover the cost of replacement parts. While the feature has good intentions, some experienced drivers find it uncomfortable—like the half-second delay in power response when starting at traffic lights. From my experience, it's fine to keep it enabled on highways or smooth roads, but for short city trips, it's better to manually turn it off to avoid unnecessary hassle. The car itself is durable and enjoyable to drive, and the choice ultimately lies with the owner.
