Today’s car interiors are filled with digital screens, push buttons, and electronic controls. Older drivers, however, may remember a time when the gear selector itself provided useful information. Along with familiar letters such as “P” for Park and “D” for Drive, certain older automatic transmissions included a less common “E.” But what exactly was it for?
In many cars produced during the 1980s and 1990s, the “E” represented Economy. It appeared during a period when fuel costs and fuel efficiency were especially important concerns. Choosing “E” altered the way the transmission operated, prompting the vehicle to move into higher gears earlier and keep the engine running at lower speeds.
This could make the ride quieter and smoother while also helping reduce fuel use when driving conditions were appropriate. Economy mode could also reduce sudden acceleration and repeated kick-down shifts. Rather than immediately delivering maximum response whenever the driver pressed the accelerator firmly, some systems provided power more gradually, encouraging a smoother and more economical driving style.
Compared with today’s vehicles, many cars from that period gave drivers a stronger sense of direct control over the mechanical parts of the vehicle. Selecting “E” was a deliberate physical choice that told the transmission to emphasize efficiency. There were no complicated digital menus or constantly adjusting computer systems—just a specific position on the gear selector that changed the way the car behaved.
Today, a dedicated “E” setting is uncommon. Modern engines, transmissions, fuel-injection technology, aerodynamic designs, and low-resistance tires are built with efficiency in mind from the start. Computer-controlled transmissions can continually determine the appropriate shift points without requiring drivers to choose a separate economy setting.
Still, the basic idea has survived.
Many modern vehicles now offer an Eco driving mode that can electronically adjust things such as throttle response, transmission operation, air-conditioning performance, and other vehicle systems. A change that once required physically moving the gear lever can now be handled automatically by the car’s computers.
Interestingly, the letter “E” has taken on another meaning in the age of electric vehicles. It may now be associated with electric power, electronic systems, or features such as e-Pedal operation and regenerative braking. The symbol has therefore moved from representing gasoline savings to being connected with an entirely different form of transportation.
That old “E” was therefore more than simply a forgotten gear-selector position. It represented a step in the transition from mechanical driving controls toward computerized efficiency. Although the physical lever setting has mostly vanished, the purpose behind it remains the same: helping a vehicle go farther while consuming less energy. The technology has changed, but the underlying goal has remained remarkably consistent.
