For drivers accustomed to modern cars, a manual gear stick usually seems straightforward. You expect to see numbers such as 1, 2, 3, 4, and 5, along with R for reverse.
But older vehicles sometimes have something a little more mysterious: an “E”.
At first glance, it can look like another gear. So what exactly does it mean?
In many older manual transmissions, the E stood for “Economy.” It was generally associated with a high-ratio gear designed to let the engine run at lower revolutions during steady cruising.
What Was the Purpose of the E Gear?
The idea was relatively simple.
When a car was already moving at a reasonable speed, selecting the economy gear could reduce the engine’s RPM. The engine didn’t have to work as hard to maintain a steady cruising speed, which could help reduce fuel consumption and engine noise.
In that sense, the E gear served a purpose similar to what many drivers today would associate with an overdrive or tall top gear.
It wasn’t designed to provide extra acceleration.
Instead, it was intended for situations where the car was already traveling smoothly and efficiently.
Why Didn’t Drivers Use It All the Time?
An economy gear generally wasn’t suitable for every driving situation.
If you were pulling away from a stop, climbing a steep hill, carrying a heavy load, or accelerating quickly, the engine needed more torque and power.
That’s where the lower gears came in.
A driver could use the numbered gears to get the vehicle moving and build speed, then select the higher-ratio economy gear once the car was cruising.
Using a tall gear at too low a speed could make the engine struggle or feel sluggish, so choosing the appropriate gear for the situation was important.
Was “E” the Same as a Normal Fifth Gear?
Not necessarily.
The exact transmission design varied between vehicles, so an E position shouldn’t automatically be assumed to be identical to fifth gear in every car.
Some older transmissions used unusual gear markings or arrangements, and manufacturers didn’t always follow the conventions modern drivers are familiar with.
That’s why the owner’s manual remains the best source for determining exactly what an E position does on a particular vehicle.
Why Did Economy Gears Help Save Fuel?
The basic principle is engine speed.
At cruising speed, a vehicle doesn’t necessarily need the engine spinning extremely quickly. A higher gear can allow the wheels to turn at the required road speed while the engine operates at a lower RPM.
Lower engine speed can mean less fuel is being consumed to maintain a steady pace, while also making the drive quieter and more relaxed.
This was especially useful on longer journeys where the vehicle spent extended periods traveling at a relatively constant speed.
What Happened to the Mysterious E?
As manual transmissions evolved, manufacturers increasingly added more conventional numbered gears.
Four-speed gearboxes became five-speed transmissions, and five-speed gearboxes were followed by six-speed designs in many vehicles.
This allowed manufacturers to provide both useful acceleration ratios and efficient cruising ratios without needing a separate letter such as E.
Modern automatic transmissions can also select efficient ratios electronically, often with several forward gears available.
As a result, the standalone E marking has become much less familiar to modern drivers.
A Small Letter With a Practical Purpose
For anyone who encounters an old gear stick marked with an E, the explanation is much less mysterious than it first appears.
In many cases, it wasn’t a secret extra performance setting or an unusual reverse gear.
It was simply an Economy setting intended for efficient cruising.
It represents an earlier approach to improving fuel economy—using gearing and lower engine speeds rather than the sophisticated electronic transmission controls found in many modern cars.
So the next time you see an old manual gear stick with an unfamiliar E, there’s a good chance you’re looking at a little piece of automotive history.
E meant Economy—and the idea behind it was surprisingly simple: keep the car moving efficiently while keeping the engine working less.
