The differences between natural aspirated and turbocharged engines. In a natural aspirated engine, the air and fuel mixture in the cylinder burns, and the resulting gas is expelled to generate power. On the other hand, a turbocharged engine reuses the burnt gases to generate additional power. While both engines consume fuel, a turbocharged engine delivers more power than a natural aspirated engine. However, there are potential drawbacks to using a turbocharged engine, which the speaker offers to discuss in a future video.
