Saturn Vehicle Startup, Idle, and Shutdown

This recording captures the engine startup, idle hum, and eventual shutdown of a Saturn vehicle. Recorded underneath the car with a microphone, it provides a detailed insight into the mechanical processes of the engine as it transitions from cold start to warm-up, maintains a steady idle, and finally shuts down. The sound includes the initial cranking of the starter motor, the roar of the engine firing up, the quiet hum during idle, and the gradual winding down as the engine cools.
