Some drivers didn’t like it. They felt the car lost its edge, its responsiveness. They switched back quickly, preferring speed over savings without realizing the balance they gave up.
Then, slowly, the letter disappeared. Engineers buried its function inside complex systems, hiding it behind “Eco” modes and software that made decisions automatically.
Yet the idea never died. Today, it lives on in modern cars—especially electric ones—where efficiency, range, and energy awareness define the driving experience in a whole new way.
