English Language & Usage Asked on April 21, 2021
If I improve a process to increase output per input, I can then do two things:
increase total output for the same total input
maintain total output by lowering total input
I’m looking for a word that means the second option.
Example:
Bob improved our combustion engine performance by X miles per gallon. We are then able to reduce fuel tank size by Y gallons, giving drivers the same range as before. Our vehicle is now more _____.
"Efficient" doesn’t seem quite right. I would describe the engine as efficient. To me efficiency is about ratio. I’m looking for a word that specifically means changes to total input, contrasting changes to total output:
Bob improved our combustion engine performance by X miles per gallon. Our existing fuel tank gives drivers an increased range of Y miles. Our vehicle is now more _____.
"Effective" is my best option so far.
Productive could be one option. WordHippo defines it as
Providing a reasonable or high degree of benefit.
Among its synonyms you will find lucrative (producing a surplus) and gainful (not so common).
But looking at another thread of connotation, I also thought of economical which can mean
Capable of maximizing productivity at no expense of extra resources.
Among its synonyms I even found fuel-efficient, which seems to match well both your context and your intuition.
