For generations, drivers have grown used to a familiar set of letters and numbers on their gear sticks. Manual cars typically display numbered gears alongside “R” for reverse, while automatic vehicles commonly show “P,” “N,” “D,” and “R,”

representing Park, Neutral, Drive, and Reverse. Occasionally, some automatics also include an “L” for Low gear. So when motorists recently noticed the letter “

E” on certain older vehicles, it naturally sparked curiosity. Many younger drivers had never encountered it before, leading to renewed interest in what this lesser-known setting actually meant.

The discussion gained attention after automotive content creator Supercar Blondie asked followers if they knew the purpose of the mysterious “E.” Experienced drivers quickly stepped in with the answer: the letter stood for “Economy.”

In select older models, this setting was designed to help improve fuel efficiency during regular driving. By adjusting engine performance to keep revolutions per minute

(RPM) lower and optimizing how the vehicle shifted, the “E” mode aimed to reduce fuel consumption, particularly during steady cruising. At a time when fuel efficiency was becoming a growing concern, this feature offered drivers a practical way to save at the pump.

As vehicle technology progressed, however, the need for a separate “Economy” gear gradually faded. Advances in engineering brought more efficient engines, smarter fuel injection systems, improved aerodynamics, and computer-controlled

transmissions that automatically adjust performance in real time. Modern cars are now capable of balancing power and efficiency without requiring drivers to manually select a special fuel-saving gear. In many ways, the old “E” setting became unnecessary as manufacturers built efficiency directly into the vehicle’s overall design.

Interestingly, the letter “E” has found new relevance in today’s automotive world — but with a different meaning. It is now most often associated with electric vehicles. Unlike traditional manual transmissions, electric cars typically operate without

multi-speed gearboxes and use simplified controls. Some models have even replaced conventional gear sticks with digital selectors or compact switches.

As the industry continues to shift toward cleaner and more advanced transportation, the driving experience keeps evolving. While the classic “E” for Economy may belong to an earlier era, it remains a small but fascinating reminder of how automotive innovation has transformed over the years.
