Engaging Introduction<\/p>\n
Let me tell you about the moment I stared at an old car\u2019s dashboard and felt completely lost.Vehicle Shopping<\/p>\n
I was helping a friend move his late father\u2019s car\u2014a 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\u2019d never seen before: \u201cE.\u201d<\/p>\n

\nI knew P, R, N, D, and even L or 2. But E? What on earth was E?<\/p>\n
\u201cElectric?\u201d I guessed. \u201cEmergency?\u201d \u201cExit?\u201d<\/p>\n
My friend shrugged. He didn\u2019t know either. We spent a good five minutes debating before I finally pulled out my phone. The answer surprised us both.<\/p>\n
For decades, most drivers never gave much thought to the letters on a car\u2019s gear selector. \u201cP\u201d meant Park. \u201cR\u201d meant Reverse. \u201cD\u201d meant Drive. Simple enough.<\/p>\n
But recently, many younger drivers have been surprised to discover an unfamiliar letter appearing on some older vehicles: \u201cE.\u201d<\/p>\n
At first glance, people assumed it might stand for \u201cElectric\u201d 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 \u201cE\u201d stood for Economy mode \u2014 an early attempt by automakers to improve fuel efficiency during everyday driving.<\/p>\n

\nLet me walk you through the fascinating history of this forgotten gear, why it disappeared, and why a new generation is just now discovering it.Autos & Vehicles<\/p>\n
What Does \u201cE\u201d Actually Stand For?<\/p>\n
Yes, it\u2019s that simple. Economy mode was designed to improve fuel efficiency by changing how the transmission shifted.<\/p>\n
What it did: When engaged, the transmission would shift to higher gears at lower RPMs (revolutions per minute). The engine wouldn\u2019t rev as high before shifting, which saved fuel.<\/p>\n
The trade-off: Acceleration was slower. The car felt \u201clazy\u201d or \u201csluggish\u201d because the transmission was prioritizing fuel economy over performance.<\/p>\n
Think of it as: An early, mechanical version of today\u2019s \u201cEco Mode\u201d in modern cars.<\/p>\n

\nThe \u201cE\u201d gear selector appeared primarily in American and Japanese cars during the late 1970s through the mid-1980s.<\/p>\n
Which cars had it?<\/p>\n
Some General Motors models (Oldsmobile, Buick, Chevrolet) with automatic overdrive transmissions<\/p>\n
Certain Honda models (especially the Accord and Civic) with \u201cEcon\u201d modeAutos & Vehicles<\/p>\n
A few Ford and Chrysler vehicles<\/p>\n
Why that era? The 1970s oil crisis (1973 and 1979) created a massive demand for fuel-efficient vehicles. Automakers scrambled to add fuel-saving features\u2014including \u201cEconomy\u201d mode on automatic transmissions.<\/p>\n
Why it wasn\u2019t standard: Not all cars had it. It was often an extra feature on higher-trim models or a brief experiment before better technology replaced it.<\/p>\n
How \u201cE\u201d Mode Actually Worked (The Mechanics)<\/p>\n
Let me explain what happened inside the transmission when you shifted to \u201cE.\u201d<\/p>\n
Standard \u201cD\u201d (Drive) mode: The transmission shifted at preset RPM points, balancing performance and fuel economy. The engine could rev higher before shifting.<\/p>\n

\n\u201cE\u201d (Economy) mode: The transmission shifted to a higher gear at lower RPMs. The engine didn\u2019t work as hard. The car accelerated more slowly, but it used less fuel.<\/p>\n
The overdrive connection: In many cars, \u201cE\u201d was essentially an \u201coverdrive on\u201d mode. Overdrive is a higher gear that reduces engine RPM at cruising speeds, saving fuel. \u201cE\u201d engaged overdrive earlier and more aggressively.Engine & Transmission<\/p>\n
The \u201cE\u201d button: Some cars didn\u2019t have an \u201cE\u201d on the gear shift\u2014they had a separate button labeled \u201cEcon\u201d or \u201cEconomy\u201d on the dashboard. Pressing it changed the transmission behavior without moving the gear selector.<\/p>\n
Why Did \u201cE\u201d Disappear?<\/p>\n
The \u201cE\u201d gear didn\u2019t last. By the late 1980s, most automakers had phased it out.<\/p>\n
Reason #1: Electronic transmission controls. Early automatic transmissions were purely mechanical or hydraulic. The \u201cE\u201d mode was a simple mechanical adjustment. When computer-controlled transmissions arrived, they could optimize shift points continuously\u2014no separate \u201cEconomy\u201d mode needed.<\/p>\n

\nReason #2: Overdrive became standard. Overdrive (a gear ratio that reduces engine RPM at highway speeds) became standard on most automatic transmissions. You didn\u2019t need an \u201cE\u201d setting to engage it\u2014it was always on in \u201cD.\u201d<\/p>\n
Reason #3: Driver confusion. Many drivers didn\u2019t understand what \u201cE\u201d meant. They worried about damaging their car. They didn\u2019t notice a difference in fuel economy. The feature wasn\u2019t worth the confusion.<\/p>\n
Reason #4: The rise of \u201cEco Mode.\u201d The idea didn\u2019t die\u2014it just moved. Modern cars often have an \u201cEco\u201d button on the dashboard that adjusts throttle response, transmission shift points, and even air conditioning behavior to save fuel. But it\u2019s no longer a physical gear selector position.Vehicle & Traffic Safety<\/p>\n
Why Are Drivers Just Discovering \u201cE\u201d Now?<\/p>\n
If \u201cE\u201d disappeared decades ago, why are people suddenly talking about it?<\/p>\n
The used car market: As used car prices have risen, more people are buying older vehicles. A 20-something buying a 1980s classic car might encounter an \u201cE\u201d on the gear shift for the first time.<\/p>\n

\nSocial media: Photos of mysterious dashboards go viral on TikTok, Instagram, and Reddit. Someone posts a picture of an unfamiliar \u201cE\u201d and asks, \u201cWhat does this mean?\u201d The post gets thousands of comments, and suddenly everyone is learning about Economy mode.<\/p>\n
Driving a parent\u2019s or grandparent\u2019s old car: Many of these cars have been sitting in garages for years. A new generation is inheriting them\u2014and discovering features their grandparents never used or explained.<\/p>\n
Nostalgia content: Car enthusiasts on YouTube are creating videos about forgotten automotive features. The \u201cE\u201d gear has become a popular topic.<\/p>\n
How Is \u201cE\u201d Different from Modern \u201cEco Mode\u201d?
\nLet me compare the old and the new.Engineering & Technology<\/p>\n
Feature Old \u201cE\u201d (Economy) Modern \u201cEco Mode\u201d
\nHow it worked Mechanical\/hydraulic transmission adjustment Computer-controlled engine, transmission, and accessories
\nWhat it changed Shift points only Throttle response, shift points, AC, cruise control, sometimes suspension
\nDriver experience Sluggish acceleration Softer throttle response (less \u201ctouchy\u201d pedal)
\nFuel savings Modest (maybe 1-2 mpg) Small but measurable (often 5-10% in city driving)
\nLocation Gear selector position Dashboard button or drive mode selector
\nToday Obsolete Common (most new cars have Eco mode)
\nThe old \u201cE\u201d was a single-purpose mechanical feature. Modern Eco mode is a sophisticated, computer-controlled system that adjusts multiple vehicle systems.Autos & Vehicles<\/p>\n
Should You Use \u201cE\u201d Mode (If You Find It)?
\nIf you own an older car with an \u201cE\u201d on the gear shift, should you use it?<\/p>\n
Yes, if:<\/p>\n
You want to save fuel (especially on the highway)<\/p>\n
You\u2019re driving on flat terrain<\/p>\n
You don\u2019t need quick acceleration<\/p>\n
You\u2019re patient<\/p>\n
No, if:<\/p>\n
You\u2019re merging onto a highway (you need acceleration)Engine & Transmission<\/p>\n
You\u2019re driving in hilly or mountainous terrain (engine will struggle)<\/p>\n
You\u2019re towing or carrying heavy loads<\/p>\n
You\u2019re driving in stop-and-go traffic (frequent shifting may be annoying)<\/p>\n
The common-sense rule: Use \u201cE\u201d for steady-speed highway cruising. Use \u201cD\u201d for everything else.<\/p>\n
What About \u201cE\u201d in Modern Cars (A Few Exceptions)?
\nWhile \u201cE\u201d on the gear selector is gone, the concept lives on.<\/p>\n
Toyota Prius (and some other hybrids): Some Toyota hybrids have a \u201cB\u201d mode (engine braking) and an \u201cECO\u201d button, but not an \u201cE\u201d on the gear selector.<\/p>\n
Electric cars: Some EVs have an \u201cE\u201d or \u201cEco\u201d button that limits acceleration and reduces climate control power to extend range.<\/p>\n
Commercial trucks: Heavy trucks sometimes have an \u201cE\u201d mode (Economy) that limits engine power and adjusts shift points for fuel savings.Vehicle & Traffic Safety<\/p>\n
The gear selector \u201cE\u201d is gone. But the idea of an economy driving mode is more common than ever.<\/p>\n
Other Forgotten Gear Selector Letters (A Quick History)
\nWhile we\u2019re talking about \u201cE,\u201d let me mention a few other letters that have confused drivers over the years.<\/p>\n
L (Low): Keeps the transmission in a low gear. Used for towing, steep hills, or engine braking. Still common on modern cars.<\/p>\n
2 (Second): Locks the transmission in second gear. Useful for driving in snow or mud. Less common now (replaced by manual mode or \u201cL\u201d).<\/p>\n
S (Sport): Changes shift points for more aggressive acceleration and engine braking. Still common on modern cars with automatic transmissions.<\/p>\n
M (Manual): Allows the driver to manually select gears using paddle shifters or the gear selector. Very common on newer cars.<\/p>\n
B (Brake \/ Engine Brake): Common on hybrids and EVs. Increases regenerative braking to recharge the battery and slow the car without using the brake pedal.<\/p>\n
The \u201cE\u201d on Old Electric Cars (A Different Meaning)
\nHere\u2019s a twist. On some very early electric cars (early 1900s), \u201cE\u201d stood for \u201cElectric.\u201dVehicle Shopping<\/p>\n
But that\u2019s a different \u201cE\u201d from a different era. If you\u2019re driving a 1980s gasoline car, the \u201cE\u201d means Economy\u2014not Electric.<\/p>\n
Frequently Asked Questions
\nDoes \u201cE\u201d stand for \u201cEco\u201d or \u201cEconomy\u201d?
\nBoth. \u201cEco\u201d is short for economy. The meaning is the same: a mode designed to save fuel.<\/p>\n
Is \u201cE\u201d the same as overdrive?
\nSort of. \u201cE\u201d often engaged overdrive earlier than standard \u201cD.\u201d But \u201cE\u201d could also adjust shift points even when overdrive wasn\u2019t engaged.<\/p>\n
Can using \u201cE\u201d damage my engine?
\nNo. It just changes how the transmission shifts. The engine isn\u2019t harmed. However, driving in \u201cE\u201d on steep hills might cause the transmission to \u201chunt\u201d (shift back and forth), which isn\u2019t ideal.<\/p>\n
Why doesn\u2019t my modern car have \u201cE\u201d?
\nBecause electronic transmission controls and \u201cEco\u201d buttons have replaced it. The functionality is still there\u2014it\u2019s just not labeled \u201cE\u201d on the gear selector.<\/p>\n
I drive an old car with \u201cE.\u201d Should I use it all the time?
\nNo. Use it for steady-speed highway driving. Use \u201cD\u201d for city driving, hills, towing, or when you need acceleration.Autos & Vehicles<\/p>\n
Will \u201cE\u201d save me a lot of gas?
\nModestly. You might see 1-2 mpg improvement on the highway. The bigger impact is driving style (smooth acceleration, steady speeds, reduced idling).<\/p>\n
My car has an \u201cE\u201d but I\u2019ve never used it. Am I missing out?
\nNot really. The fuel savings are small. If you\u2019re happy with your car\u2019s performance in \u201cD,\u201d you don\u2019t need to use \u201cE.\u201d<\/p>\n
A Final Thought: The Forgotten \u201cE\u201d
\nHere\u2019s what I love about the story of \u201cE.\u201d<\/p>\n
It\u2019s a reminder that cars\u2014like language, fashion, and technology\u2014evolve. Features that seemed cutting-edge in one decade become obsolete, forgotten, and then rediscovered by a new generation.<\/p>\n
The \u201cE\u201d on an old gear shift isn\u2019t just a letter. It\u2019s 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.<\/p>\n
And now, when you see that mysterious \u201cE,\u201d you won\u2019t guess \u201cElectric\u201d or \u201cEmergency.\u201d You\u2019ll know the truth.<\/p>\n
It stands for Economy. A small, forgotten effort to save gas\u2014one gear shift at a time.Engine & Transmission<\/p>\n
Now I\u2019d love to hear from you. Have you ever seen an \u201cE\u201d on an old car\u2019s gear shift? Did you know what it meant? Have you driven a car with Economy mode? Drop a comment below \u2013 I read every single one.<\/p>\n
