For many years, car gear selectors followed patterns that drivers could understand almost instantly. Manual vehicles usually displayed numbered gears along with “R” for reverse, while automatic cars commonly used “P” for park, “N” for neutral, “D” for drive, and “R” for reverse.

Because these symbols became so familiar, many drivers stopped paying close attention to other letters or markings that appeared on older vehicles.

That is why some people are surprised when they notice an unfamiliar “E” on the gear selector of certain older cars. For younger drivers especially, the symbol may seem confusing because it is rarely seen in modern vehicles today.

In many older automotive designs, the letter “E” stood for “Economy.”

This setting was designed to help reduce fuel consumption and make the vehicle more efficient, especially during steady driving or longer trips. Instead of focusing on power or quick acceleration, Economy mode encouraged smoother, more fuel-conscious performance.

When activated, the system could adjust how the engine and transmission behaved. In some vehicles, it helped lower engine speed, soften acceleration, or change shift timing so the car used less fuel. Drivers often used this feature on highways or during calm, consistent driving when performance was less important than saving gas.

The “E” setting reflected an earlier approach to fuel efficiency. Instead of relying entirely on advanced computer systems, drivers had a visible option they could select when they wanted the car to operate more economically.

Today, dedicated “E” gear markings are much less common. Modern vehicles usually handle fuel-saving adjustments automatically through electronic control systems, eco modes, hybrid technology, start-stop systems, and advanced transmission programming.

Still, the old “E” symbol remains an interesting reminder of how automotive design has evolved.

What once required a simple manual setting is now managed by sophisticated systems working quietly in the background — all with the same goal: helping drivers use fuel more efficiently and make everyday driving more practical.
