unsupercharged

Lacking forced induction

Not supercharged—lacking a supercharger or turbocharger to boost engine power.

The term appears mainly in automotive contexts to distinguish naturally aspirated engines from forced-induction variants: The unsupercharged version produces 300 horsepower.

Occasionally used figuratively for anything lacking extra boost or enhancement.
