The start-stop system has long been standard in modern cars, yet drivers still wonder: should it be turned off, and does it harm the vehicle? The answer isn't straightforward. Its main purpose is to save fuel and reduce emissions. In urban settings, especially at traffic lights, it works effectively.Tests show fuel savings can reach up to 1.2 liters per 100 kilometers, which is noticeable with high fuel prices. However, this technology has a downside. Frequent engine starts increase strain on the starter, battery, and belts.Manufacturers account for this by reinforcing components, but with heavy use, wear can accelerate. For instance, the starter might need replacement after just 100,000 kilometers. It's important to note that the system doesn't cause critical damage to the engine or transmission.In fact, when used correctly, it can even reduce clutch load. Overall, start-stop remains a useful tool, particularly for city driving. If needed, drivers can always disable it when road conditions make the system less efficient.Start-stop represents a compromise between ecology and comfort. In most cases, it's justified, but driving style and usage conditions should be considered.
