Most drivers recognize the standard markings on gear selectors. Manual cars show numbered gears and “R” for reverse, while automatics display “P,” “N,” “D,” and “R,” sometimes with an “L” for low gear.

Because this format has remained consistent for decades, spotting an unfamiliar “E” on older gear sticks has puzzled some motorists. The letter seemed out of place among the traditional symbols.

In certain older models, however, “E” simply stood for “Economy.” It was a feature designed to improve fuel efficiency during everyday driving.

Economy mode adjusted how the transmission behaved, encouraging lower engine revolutions per minute and smoother gear changes. This helped reduce fuel consumption, especially on highways.

At the time, it offered drivers a more conscious way to manage fuel use. By selecting “E,” motorists could prioritize efficiency over rapid acceleration or higher performance.

As automotive technology advanced, this separate setting became less necessary. Modern vehicles use computerized engine management systems and refined transmissions to optimize efficiency automatically.

Today’s cars adjust performance in real time based on speed, terrain, and driving habits. Because of these improvements, the dedicated “E” marking gradually disappeared from most gear selectors.

Interestingly, the letter “E” now carries a different meaning in the automotive world. It is commonly associated with electric vehicles, symbolizing a shift toward alternative energy. Once a mechanical tool for saving fuel, “E” has become a broader sign of efficiency and innovation in transportation.
