What Did the “E” Mean on Older Car Gear Shifters? The Forgotten Setting Explained
If you learned to drive in the 1980s or 1990s, you may remember something that seems unusual on today’s automatic gear shifters.
Alongside familiar letters like P, R, N, and D, some older cars had another setting:
E.
But what did that mysterious letter actually mean?
For many drivers, the answer is a fascinating reminder of how much car technology has changed.
What Did the “E” Mean?
In many vehicles from the 1980s and 1990s, “E” stood for Economy.
The setting was designed during an era when fuel efficiency was an important concern for drivers and automakers.
Selecting E changed the way the automatic transmission operated. The transmission could shift into higher gears sooner and keep engine speeds lower, depending on the vehicle and driving conditions.
The goal was simple:
Use less fuel while providing smoother, calmer driving.

How Did Economy Mode Work?
When the driver selected the economy setting, the transmission generally became less eager to hold lower gears or perform aggressive downshifts.
Instead of responding immediately to every heavy press of the accelerator, some systems were designed to encourage more gradual acceleration.
That could result in:
Earlier upshifts
Lower engine speeds
Smoother acceleration
Quieter cruising
Potentially lower fuel consumption under suitable conditions
The exact behavior varied by vehicle, so the “E” setting did not work identically in every car.
But the basic idea was the same: encourage more efficient driving by changing transmission behavior.
Why Did Older Cars Need a Separate Economy Setting?
Modern drivers are accustomed to cars that automatically adjust dozens of things behind the scenes.
Older vehicles were different.
Many relied more directly on mechanical components and relatively simple electronic controls. If a driver wanted to prioritize fuel economy, a physical gear-selector position could provide a straightforward way to change how the transmission behaved.
There were no large digital displays filled with driving modes.
No touchscreen menu.
No smartphone-like settings screen.
You simply moved the gear lever.
That physical action told the transmission that efficiency was the priority.
The Driving Experience Was Different
For drivers accustomed to modern vehicles, an older economy setting can seem surprisingly simple.
Moving the shifter into E wasn't just selecting a number or changing something on a screen.
It could noticeably influence the way the car responded.
The vehicle might feel less eager to accelerate, shift earlier, and maintain lower engine speeds during normal driving.
In other words, the car was encouraging the driver to take a calmer approach.
That could be especially useful during steady cruising or everyday driving when maximum acceleration wasn't necessary.
Why Did the “E” Gear Position Disappear?
Today, you're much less likely to find a dedicated E position on an automatic transmission.
That's largely because modern vehicles can manage efficiency electronically.
Modern engines and transmissions are designed around computerized control systems that can continuously monitor driving conditions and adjust their behavior.
Instead of asking the driver to select an economy gear, the vehicle can automatically determine when to shift, how aggressively to respond, and how to balance performance with fuel efficiency.
Other improvements have also contributed to modern efficiency, including:
More advanced engine management
Electronic fuel injection
More sophisticated automatic transmissions
Improved aerodynamics
Lower-rolling-resistance tires
Computer-controlled powertrain systems
The result is that much of what once required a dedicated E setting can now happen automatically.
The “E” Setting Didn't Really Disappear
Although the old physical E position has largely faded away, the idea behind it is still very much alive.
Look at the controls in many modern vehicles and you'll find an Eco driving mode.
The name may be slightly different, but the basic goal is familiar.
Modern Eco modes can electronically influence things such as:
Throttle response
Transmission behavior
Air-conditioning operation
Engine management
Other vehicle systems
Instead of physically moving the transmission into an economy position, the driver can often press a button or select a setting on a screen.
The computer then handles the changes.
From a Gear Lever to a Computer
That's perhaps the most interesting part of the story.
The old E setting represents a period when drivers had a more direct relationship with the mechanical systems in their cars.
You moved the lever.
You felt the difference.
Today, much of that work happens electronically and almost invisibly.
A modern vehicle can constantly monitor conditions and make adjustments without the driver even realizing what's happening.
What once required a physical transmission setting can now be managed by software.
What Does “E” Mean in Modern Cars?
There's another interesting twist.
In today's automotive world, the letter E can mean something very different.
With the growth of electric and electrified vehicles, “E” may be associated with:
Electric propulsion
Electronic systems
Regenerative braking
E-Pedal features
Electrified driving technologies
So the same letter that once represented Economy in some older automatic transmissions can now be connected with an entirely different generation of automotive technology.
From Saving Gas to Saving Energy
That's what makes the old E so interesting.
Decades ago, the focus was largely on making a gasoline-powered vehicle use less fuel.
Today, automotive engineers are also working with hybrid systems, battery-electric vehicles, regenerative braking, sophisticated software, and increasingly computerized powertrains.
The technology has changed dramatically.
But the underlying goal remains surprisingly familiar:
Get more useful travel from the energy available.
What Happened to Those Old Gear Shifters?
For anyone who remembers seeing E on an old gear selector, it can feel like a little piece of automotive history.
Modern cars may have replaced the physical economy position with buttons, computers, and electronic driving modes, but the principle behind it hasn't vanished.
The old E was a simple answer to a simple question:
How can the car use less fuel during everyday driving?
Today, your vehicle may answer that question automatically.
The physical lever is gone.
The computer has taken its place.
And that small change tells a much bigger story about how automobiles evolved from increasingly mechanical machines into sophisticated computer-controlled transportation systems.
Final Thought
The next time you see an old photograph of a car's gear selector with an unfamiliar E, you'll know that it wasn't just a random letter.
For many vehicles, it stood for Economy—a setting designed to encourage earlier shifting, lower engine speeds, and more efficient driving.
The technology moved forward.
The controls became smarter.
But the goal behind that little E remains remarkably familiar: use energy wisely and go farther.
