For many years, car gear layouts were simple and consistent. Manual cars used numbered gears plus “R” for reverse, while automatics typically showed “P,” “N,” “D,” and “R.” Because of this standardization, most drivers rarely questioned what each letter meant.

That’s why the appearance of an “E” on some older gear sticks has recently sparked curiosity, especially among younger drivers who had never seen it before.

The “E” stood for “Economy.” It was a mode designed to improve fuel efficiency by lowering engine RPM, adjusting throttle response, and sometimes altering shift timing. In a time before advanced computers, this was a practical, mechanical way to save fuel.

Drivers would typically use the Economy setting during steady-speed driving, such as on highways. The trade-off was slower acceleration and reduced responsiveness, but many accepted this in exchange for better fuel consumption.

The “E” gear reflects a transitional era in automotive design, when engineers balanced performance with growing concerns about fuel efficiency. Unlike today, drivers had to actively choose efficiency rather than rely on automatic systems.

As technology advanced, this feature became unnecessary. Modern vehicles now use computerized systems to optimize fuel use in real time, adjusting engine and transmission behavior without driver input.

Although the “E” gear has largely disappeared, its purpose still exists—just in a more advanced and invisible form.

Today, the letter “E” has taken on a new meaning in the automotive world, often associated with electric vehicles. Instead of representing Economy mode, it now symbolizes electrification and the shift toward more efficient, environmentally friendly transportation.

In the end, the “E” gear is a small but meaningful piece of automotive history, showing how the pursuit of efficiency has evolved from manual control to smart, automated systems.
