I've been driving a Mercedes for several years, and that ECM gear refers to the Economy Mode gear, which is a more fuel-efficient option in the transmission settings. For daily commuting, I always switch to E mode, and the driving experience is particularly smooth—unlike the aggressive feel of Sport mode. There's no noticeable jerkiness, and the RPM stays low, saving quite a bit of fuel over a hundred kilometers. Once, I tried E mode on the highway while driving from the city to the suburbs, and the fuel consumption indeed dropped by about 10%. This mode is especially suitable for congested urban roads or long-distance trips, as it reduces the need for frequent throttle adjustments and gear shifts—the car adjusts itself perfectly. I only switch back to Sport mode occasionally when I feel like pushing the car, but most of the time, I find E mode both economical and reassuring, especially when fuel prices remain high—it has genuinely helped me save a lot on gas. If you also drive a Mercedes, why not give this mode a try? The driving experience can be quite different.
