Naturally Aspirated
An engine that draws air at atmospheric pressure without forced induction.
Naturally aspirated (NA) engines rely solely on atmospheric pressure to fill the cylinders. They offer linear power delivery, instant throttle response, and often higher redlines than turbocharged equivalents. Classic examples include the Ferrari 458's 9,000 RPM V8, Porsche GT3's flat-six, and Lexus LFA's V10. NA engines are becoming rare due to emissions regulations.
