When selected, Economy mode changed how the car shifted gears. The transmission shifted earlier, kept engine revs lower, and reduced aggressive acceleration. The goal was simple: use less fuel and make the drive smoother.
For drivers, it meant choosing between power and efficiency. The car would feel calmer and less responsive, but it could help stretch a tank of fuel farther, especially during normal city or highway driving.
Today, the old “E” has mostly disappeared, replaced by Eco buttons, software settings, and electric vehicle energy modes. But the idea remains the same: reduce waste, save energy, and travel farther with less.
