What is the reason for the increase in Mercedes-Benz eco mode display after startup?

Mercedes-Benz eco mode display increasing after startup means the fuel-saving mode is activated. ECO is a symbol of green driving mode, which can be divided into passive and active forms. Modes: Generally, it can be divided into passive ECO driving mode and active ECO driving mode. The passive ECO driving mode mainly serves as a reminder and guidance function. The active ECO driving mode usually has a button. After activation, a series of driving-related settings will change, such as a smaller throttle opening corresponding to the same accelerator pedal depth (the accelerator becomes less sensitive), the transmission shift logic prioritizing fuel economy (earlier upshifts), and some vehicles will also adjust the air conditioning output power simultaneously. When to enable ECO: Enabling ECO is most effective in urban congested traffic conditions. In urban congested traffic, strong power is not required, and the frequent stop-and-go leads to higher fuel consumption. Enabling ECO mode at this time can not only reduce fuel consumption but also make driving more comfortable.
Using ECO mode to save fuel should be a good thing, but after activating it on my Mercedes-Benz E-Class, the fuel consumption display sometimes increases, which puzzled me for a long time. One possible reason is driving habits: I usually tend to accelerate aggressively by pressing the throttle hard. After ECO mode limits power output, I subconsciously press the pedal harder, causing the engine to compensate by injecting more fuel, leading to a temporary spike in fuel consumption. Secondly, the system needs time to initialize. When ECO mode is first activated, the vehicle is adjusting transmission logic and aerodynamic settings. During these few seconds, sensors might inaccurately report increased consumption. It's recommended to activate ECO before highway cruising and avoid using it in urban traffic jams, as frequent acceleration and deceleration can increase fuel consumption. Also, remember to check for software updates, as the Mercedes system occasionally needs refreshing to avoid minor bugs. In short, adapting to a smoother driving style is key. After paying attention to this, I actually managed to save on fuel costs.
As an enthusiast with some research into automotive systems, I've analyzed the reasons for increased fuel consumption displayed after ECO mode activation. The core of ECO mode is to optimize engine combustion efficiency by limiting torque output and adjusting shift patterns to save fuel. However, in actual driving conditions, if the driver rapidly presses the accelerator for quick acceleration, the system fails to respond promptly and is forced to inject more fuel, causing a temporary spike in displayed fuel consumption. Another possibility could be sensor calibration errors or software glitches leading to false readings, as electronic control units in Mercedes-Benz models occasionally require updates. Environmental factors like high AC load during cold starts also contribute to extra fuel consumption. The solution is to maintain gentle acceleration after enabling ECO mode, allowing the system time to adapt, or visit a 4S shop to scan for trouble codes to check for potential hardware issues. This ensures both environmental friendliness and cost savings.
