What the “E” on Old Car Gear Shifts Really Means — And Why Drivers Are Just Discovering It Now

Engaging Introduction
Let me tell you about the moment I stared at an old car’s dashboard and felt completely lost.

I was helping a friend move his late father’s car—a 1980s sedan that had been sitting in a garage for years. The upholstery smelled like memories. The radio was analog. And the gear shift had a letter I’d never seen before: “E.”

I knew P, R, N, D, and even L or 2. But E? What on earth was E?

“Electric?” I guessed. “Emergency?” “Exit?”

My friend shrugged. He didn’t know either. We spent a good five minutes debating before I finally pulled out my phone. The answer surprised us both.

For decades, most drivers never gave much thought to the letters on a car’s gear selector. “P” meant Park. “R” meant Reverse. “D” meant Drive. Simple enough.

But recently, many younger drivers have been surprised to discover an unfamiliar letter appearing on some older vehicles: “E.”

At first glance, people assumed it might stand for “Electric” or some forgotten transmission setting. But the truth is far more interesting. Long before modern fuel-saving technology and smart computerized driving systems, the mysterious “E” stood for Economy mode — an early attempt by automakers to improve fuel efficiency during everyday driving.

Let me walk you through the fascinating history of this forgotten gear, why it disappeared, and why a new generation is just now discovering it.
