Naturally Aspirated Engine
A naturally aspirated engine draws in air at atmospheric pressure, without a turbocharger or supercharger.
What is Naturally Aspirated Engine?
Throttle response is direct, with no turbo lag. Power usually rises steadily with engine speed. It needs more displacement than a turbo engine for the same power. Many enthusiasts value the sound and linear response of naturally aspirated engines.
How it works
Only the downward movement of the pistons pulls air into the cylinders.
Why it matters for your car
Power drops at high altitude, where the air is thinner. Fewer parts can mean simpler maintenance than turbo engines.
