For generations, drivers have grown accustomed to the familiar arrangement of letters and numbers etched into their car gear sticks, symbols that quietly dictate how a vehicle moves, pauses, and reverses through the world. Manual transmissions traditionally display a sequence of ascending numbers accompanied by an “R” for reverse, while automatic vehicles typically feature “P,” “R,” “N,” and “D,” standing for Park, Reverse, Neutral, and Drive. Some also include an “L” for low gear, useful for towing or navigating steep terrain.
These markings have become so standardized that most motorists rarely stop to consider their origins or variations. That is why the sudden rediscovery of the letter “E” on certain older gear sticks has sparked such widespread curiosity. Many drivers, especially younger ones who learned to drive in vehicles equipped with advanced automatic systems or electric drivetrains, had never encountered the marking before. Seeing it felt like uncovering a relic from a forgotten mechanical era. Questions quickly followed: What did the “E” mean? Why was it there? And why did it seem to vanish from modern cars?
