For many drivers, car gear labels once felt simple and familiar. Manual cars usually showed numbered gears and “R” for reverse, while automatics commonly displayed “P,” “N,” “D,” and “R.”
Because of this, some drivers were surprised to notice an extra letter on certain older vehicles: “E.”
The article explains that “E” stood for “Economy.”
This setting was designed to improve fuel efficiency by changing how the car performed. It lowered engine RPM, adjusted throttle response, and sometimes changed shift timing to reduce fuel use.
Drivers often used this mode during long highway trips or steady-speed driving.
The main benefit was better fuel economy, though it came with a trade-off. Cars in Economy mode typically had slower acceleration and reduced responsiveness.
At the time, this feature gave drivers direct control over efficiency.
The article describes it as part of a transitional period in car design, when manufacturers were beginning to focus more on fuel savings.
Unlike many modern vehicles, older cars required drivers to manually choose between stronger performance and better efficiency.
As automotive technology improved, this system gradually became outdated.
Modern vehicles now use advanced computer systems that automatically manage fuel consumption in real time. These systems adjust engine and transmission behavior without requiring driver input.
Because of this automation, the “E” gear has mostly disappeared from newer cars.
Still, its original purpose has not vanished.
The article notes that today’s focus on efficiency continues, just in a more advanced form.
Interestingly, the letter “E” has also gained a newer meaning in the car industry.
Instead of representing Economy mode, it is now often linked to electric vehicles and cleaner transportation.
Overall, the “E” gear is presented as a small but interesting piece of automotive history.
It reflects how cars have evolved from simple mechanical controls to smarter, more automated systems designed to improve fuel use and efficiency with less driver effort.
