Meaning)

Here’s a twist. On some very early electric cars (early 1900s), “E” stood for “Electric.”

But that’s a different “E” from a different era. If you’re driving a 1980s gasoline car, the “E” means Economy—not Electric.

Frequently Asked Questions

Does “E” stand for “Eco” or “Economy”?
Both. “Eco” is short for economy. The meaning is the same: a mode designed to save fuel.

Is “E” the same as overdrive?
Sort of. “E” often engaged overdrive earlier than standard “D.” But “E” could also adjust shift points even when overdrive wasn’t engaged.

Can using “E” damage my engine?
No. It just changes how the transmission shifts. The engine isn’t harmed. However, driving in “E” on steep hills might cause the transmission to “hunt” (shift back and forth), which isn’t ideal.

Why doesn’t my modern car have “E”?
Because electronic transmission controls and “Eco” buttons have replaced it. The functionality is still there—it’s just not labeled “E” on the gear selector.

I drive an old car with “E.” Should I use it all the time?
No. Use it for steady-speed highway driving. Use “D” for city driving, hills, towing, or when you need acceleration.

Will “E” save me a lot of gas?
Modestly. You might see 1-2 mpg improvement on the highway. The bigger impact is driving style (smooth acceleration, steady speeds, reduced idling).

My car has an “E” but I’ve never used it. Am I missing out?
Not really. The fuel savings are small. If you’re happy with your car’s performance in “D,” you don’t need to use “E.”

A Final Thought: The Forgotten “E”

Here’s what I love about the story of “E.”

It’s a reminder that cars—like language, fashion, and technology—evolve. Features that seemed cutting-edge in one decade become obsolete, forgotten, and then rediscovered by a new generation.

The “E” on an old gear shift isn’t just a letter. It’s a time capsule. It tells you about the 1970s oil crisis, the rise of fuel economy concerns, and the mechanical ingenuity of early automatic transmissions.

And now, when you see that mysterious “E,” you won’t guess “Electric” or “Emergency.” You’ll know the truth.

It stands for Economy. A small, forgotten effort to save gas—one gear shift at a time.

Now I’d love to hear from you. Have you ever seen an “E” on an old car’s gear shift? Did you know what it meant? Have you driven a car with Economy mode? Drop a comment below – I read every single one.

Now go check your gear shift. You never know what letters you’ll find. 🚗🔧⛽
