Economy mode was designed to improve fuel efficiency by changing how the transmission shifted.<\/p>\n<p class=\"ds-markdown-paragraph\">What it did:\u00a0When engaged, the transmission would shift to higher gears at lower RPMs (revolutions per minute). The engine wouldn&#8217;t rev as high before shifting, which saved fuel.<\/p>\n<p class=\"ds-markdown-paragraph\">The trade-off:\u00a0Acceleration was slower. The car felt &#8220;lazy&#8221; or &#8220;sluggish&#8221; because the transmission was prioritizing fuel economy over performance.<\/p>\n<p class=\"ds-markdown-paragraph\">Think of it as:\u00a0An early, mechanical version of today&#8217;s &#8220;Eco Mode&#8221; in modern cars.<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<h2>When Did the &#8220;E&#8221; Gear Exist?<\/h2>\n<p class=\"ds-markdown-paragraph\">The &#8220;E&#8221; gear selector appeared primarily in American and Japanese cars during the\u00a0late 1970s through the mid-1980s.<\/p>\n<p class=\"ds-markdown-paragraph\">Which cars had it?<\/p>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\">Some General Motors models (Oldsmobile, Buick, Chevrolet) with automatic overdrive transmissions<\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\">Certain Honda models (especially the Accord and Civic) with &#8220;Econ&#8221; mode<\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\">A few Ford and Chrysler vehicles<\/p>\n<\/li>\n<\/ul>\n<p class=\"ds-markdown-paragraph\">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 &#8220;Economy&#8221; mode on automatic transmissions.<\/p>\n<p class=\"ds-markdown-paragraph\">Why it wasn&#8217;t standard:\u00a0Not 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<hr \/>\n<h2>How &#8220;E&#8221; Mode Actually Worked (The Mechanics)<\/h2>\n<div class=\"google-auto-placed ap_container\">\n<p>&nbsp;<\/p>\n<div id=\"aswift_5_host\"><\/div>\n<p>&nbsp;<\/p>\n<\/div>\n<p class=\"ds-markdown-paragraph\">Let me explain what happened inside the transmission when you shifted to &#8220;E.&#8221;<\/p>\n<p class=\"ds-markdown-paragraph\">Standard &#8220;D&#8221; (Drive) mode: The transmission shifted at preset RPM points, balancing performance and fuel economy. The engine could rev higher before shifting.<\/p>\n<p class=\"ds-markdown-paragraph\">&#8220;E&#8221; (Economy) mode: The transmission shifted to a higher gear at lower RPMs. The engine didn&#8217;t work as hard. The car accelerated more slowly, but it used less fuel.<\/p>\n<p class=\"ds-markdown-paragraph\">The overdrive connection:\u00a0In many cars, &#8220;E&#8221; was essentially an &#8220;overdrive on&#8221; mode. Overdrive is a higher gear that reduces engine RPM at cruising speeds, saving fuel. &#8220;E&#8221; engaged overdrive earlier and more aggressively.<\/p>\n<div class=\"google-auto-placed ap_container\">\n<p>&nbsp;<\/p>\n<div id=\"aswift_8_host\"><\/div>\n<p>&nbsp;<\/p>\n<\/div>\n<p class=\"ds-markdown-paragraph\">The &#8220;E&#8221; button:\u00a0Some cars didn&#8217;t have an &#8220;E&#8221; on the gear shift\u2014they had a separate button labeled &#8220;Econ&#8221; or &#8220;Economy&#8221; on the dashboard. Pressing it changed the transmission behavior without moving the gear selector.<\/p>\n<hr \/>\n<h2>Why Did &#8220;E&#8221; Disappear?<\/h2>\n<div class=\"google-auto-placed ap_container\">\n<p>&nbsp;<\/p>\n<div id=\"aswift_9_host\"><\/div>\n<p>&nbsp;<\/p>\n<\/div>\n<p class=\"ds-markdown-paragraph\">The &#8220;E&#8221; gear didn&#8217;t last. By the late 1980s, most automakers had phased it out.<\/p>\n<p class=\"ds-markdown-paragraph\">Reason #1: Electronic transmission controls.\u00a0Early automatic transmissions were purely mechanical or hydraulic. The &#8220;E&#8221; mode was a simple mechanical adjustment. When computer-controlled transmissions arrived, they could optimize shift points continuously\u2014no separate &#8220;Economy&#8221; mode needed.<\/p>\n<div class=\"google-auto-placed ap_container\">\n<p>&nbsp;<\/p>\n<div id=\"aswift_10_host\">\n<div class=\"google-aiuf\" data-google-ad-efd=\"true\"><\/div>\n<\/div>\n<p>&nbsp;<\/p>\n<\/div>\n<p class=\"ds-markdown-paragraph\">Reason #2: Overdrive became standard. Overdrive (a gear ratio that reduces engine RPM at highway speeds) became standard on most automatic transmissions. You didn&#8217;t need an &#8220;E&#8221; setting to engage it\u2014it was always on in &#8220;D.&#8221;<\/p>\n<p class=\"ds-markdown-paragraph\">Reason #3: Driver confusion. Many drivers didn&#8217;t understand what &#8220;E&#8221; meant. They worried about damaging their car. They didn&#8217;t notice a difference in fuel economy. The feature wasn&#8217;t worth the confusion.<\/p>\n<p class=\"ds-markdown-paragraph\">Reason #4: The rise of &#8220;Eco Mode.&#8221;\u00a0The idea didn&#8217;t die\u2014it just moved. Modern cars often have an &#8220;Eco&#8221; button on the dashboard that adjusts throttle response, transmission shift points, and even air conditioning behavior to save fuel. But it&#8217;s no longer a physical gear selector position.<\/p>\n<hr \/>\n<h2>Why Are Drivers Just Discovering &#8220;E&#8221; Now?<\/h2>\n<div class=\"google-auto-placed ap_container\">\n<p>&nbsp;<\/p>\n<div id=\"aswift_13_host\"><\/div>\n<p>&nbsp;<\/p>\n<\/div>\n<p class=\"ds-markdown-paragraph\">If &#8220;E&#8221; disappeared decades ago, why are people suddenly talking about it?<\/p>\n<p class=\"ds-markdown-paragraph\">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 &#8220;E&#8221; on the gear shift for the first time.<\/p>\n<p class=\"ds-markdown-paragraph\">Social media:\u00a0Photos of mysterious dashboards go viral on TikTok, Instagram, and Reddit. Someone posts a picture of an unfamiliar &#8220;E&#8221; and asks, &#8220;What does this mean?&#8221; The post gets thousands of comments, and suddenly everyone is learning about Economy mode.<\/p>\n<div class=\"google-auto-placed ap_container\">\n<p>&nbsp;<\/p>\n<div id=\"aswift_15_host\">\n<div class=\"google-aiuf\" data-google-ad-efd=\"true\"><\/div>\n<\/div>\n<p>&nbsp;<\/p>\n<\/div>\n<p class=\"ds-markdown-paragraph\">Driving a parent&#8217;s or grandparent&#8217;s old car:\u00a0Many 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<p class=\"ds-markdown-paragraph\">Nostalgia content:\u00a0Car enthusiasts on YouTube are creating videos about forgotten automotive features. The &#8220;E&#8221; gear has become a popular topic.<\/p>\n<hr \/>\n<h2>How Is &#8220;E&#8221; Different from Modern &#8220;Eco Mode&#8221;?<\/h2>\n<p class=\"ds-markdown-paragraph\">Let me compare the old and the new.<\/p>\n<div class=\"ds-scroll-area ds-scroll-area--show-on-focus-within _1210dd7 c03cafe9\">\n<div class=\"ds-scroll-area__gutters\">\n<div class=\"ds-scroll-area__horizontal-gutter\"><\/div>\n<div class=\"ds-scroll-area__vertical-gutter\"><\/div>\n<\/div>\n<table>\n<thead>\n<tr>\n<th>Feature<\/th>\n<th>Old &#8220;E&#8221; (Economy)<\/th>\n<th>Modern &#8220;Eco Mode&#8221;<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>How it worked<\/td>\n<td>Mechanical\/hydraulic transmission adjustment<\/td>\n<td>Computer-controlled engine, transmission, and accessories<\/td>\n<\/tr>\n<tr>\n<td>What it changed<\/td>\n<td>Shift points only<\/td>\n<td>Throttle response, shift points, AC, cruise control, sometimes suspension<\/td>\n<\/tr>\n<tr>\n<td>Driver experience<\/td>\n<td>Sluggish acceleration<\/td>\n<td>Softer throttle response (less &#8220;touchy&#8221; pedal)<\/td>\n<\/tr>\n<tr>\n<td>Fuel savings<\/td>\n<td>Modest (maybe 1-2 mpg)<\/td>\n<td>Small but measurable (often 5-10% in city driving)<\/td>\n<\/tr>\n<tr>\n<td>Location<\/td>\n<td>Gear selector position<\/td>\n<td>Dashboard button or drive mode selector<\/td>\n<\/tr>\n<tr>\n<td>Today<\/td>\n<td>Obsolete<\/td>\n<td>Common (most new cars have Eco mode)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p class=\"ds-markdown-paragraph\">The old &#8220;E&#8221; was a single-purpose mechanical feature.

Used for towing, steep hills, or engine braking. Still common on modern cars.<\/p>\n<p class=\"ds-markdown-paragraph\">2 (Second):\u00a0Locks the transmission in second gear. Useful for driving in snow or mud. Less common now (replaced by manual mode or &#8220;L&#8221;).<\/p>\n<p class=\"ds-markdown-paragraph\">S (Sport):\u00a0Changes shift points for more aggressive acceleration and engine braking. Still common on modern cars with automatic transmissions.<\/p>\n<p class=\"ds-markdown-paragraph\">M (Manual):\u00a0Allows the driver to manually select gears using paddle shifters or the gear selector. Very common on newer cars.<\/p>\n<p class=\"ds-markdown-paragraph\">B (Brake \/ Engine Brake):\u00a0Common on hybrids and EVs. Increases regenerative braking to recharge the battery and slow the car without using the brake pedal.<\/p>\n<hr \/>\n<h2>The &#8220;E&#8221; on Old Electric Cars (A Different Meaning)<\/h2>\n<p class=\"ds-markdown-paragraph\">Here&#8217;s a twist. On some very early electric cars (early 1900s), &#8220;E&#8221; stood for &#8220;Electric.&#8221;<\/p>\n<p class=\"ds-markdown-paragraph\">But that&#8217;s a different &#8220;E&#8221; from a different era. If you&#8217;re driving a 1980s gasoline car, the &#8220;E&#8221; means Economy\u2014not Electric.<\/p>\n<hr \/>\n<h2>Frequently Asked Questions<\/h2>\n<p class=\"ds-markdown-paragraph\">Does &#8220;E&#8221; stand for &#8220;Eco&#8221; or &#8220;Economy&#8221;?<br \/>\nBoth. &#8220;Eco&#8221; is short for economy. The meaning is the same: a mode designed to save fuel.<\/p>\n<p class=\"ds-markdown-paragraph\">Is &#8220;E&#8221; the same as overdrive?<br \/>\nSort of. &#8220;E&#8221; often engaged overdrive earlier than standard &#8220;D.&#8221; But &#8220;E&#8221; could also adjust shift points even when overdrive wasn&#8217;t engaged.<\/p>\n<p class=\"ds-markdown-paragraph\">Can using &#8220;E&#8221; damage my engine?<br \/>\nNo. It just changes how the transmission shifts. The engine isn&#8217;t harmed. However, driving in &#8220;E&#8221; on steep hills might cause the transmission to &#8220;hunt&#8221; (shift back and forth), which isn&#8217;t ideal.<\/p>\n<p class=\"ds-markdown-paragraph\">Why doesn&#8217;t my modern car have &#8220;E&#8221;?<br \/>\nBecause electronic transmission controls and &#8220;Eco&#8221; buttons have replaced it. The functionality is still there\u2014it&#8217;s just not labeled &#8220;E&#8221; on the gear selector.<\/p>\n<p class=\"ds-markdown-paragraph\">I drive an old car with &#8220;E.&#8221; Should I use it all the time?<br \/>\nNo. Use it for steady-speed highway driving. Use &#8220;D&#8221; for city driving, hills, towing, or when you need acceleration.<\/p>\n<p class=\"ds-markdown-paragraph\">Will &#8220;E&#8221; save me a lot of gas?<br \/>\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<p class=\"ds-markdown-paragraph\">My car has an &#8220;E&#8221; but I&#8217;ve never used it. Am I missing out?<br \/>\nNot really. The fuel savings are small. If you&#8217;re happy with your car&#8217;s performance in &#8220;D,&#8221; you don&#8217;t need to use &#8220;E.&#8221;<\/p>\n<hr \/>\n<h2>A Final Thought: The Forgotten &#8220;E&#8221;<\/h2>\n<p class=\"ds-markdown-paragraph\">Here&#8217;s what I love about the story of &#8220;E.&#8221;<\/p>\n<p class=\"ds-markdown-paragraph\">It&#8217;s 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<p class=\"ds-markdown-paragraph\">The &#8220;E&#8221; on an old gear shift isn&#8217;t just a letter. It&#8217;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.<\/p>\n<p class=\"ds-markdown-paragraph\">And now, when you see that mysterious &#8220;E,&#8221; you won&#8217;t guess &#8220;Electric&#8221; or &#8220;Emergency.&#8221; You&#8217;ll know the truth.<\/p>\n<p class=\"ds-markdown-paragraph\">It stands for Economy. A small, forgotten effort to save gas\u2014one gear shift at a time.<\/p>\n<p class=\"ds-markdown-paragraph\">Now I&#8217;d love to hear from you.\u00a0Have you ever seen an &#8220;E&#8221; on an old car&#8217;s gear shift?
