Departure of Car 4

The audio begins with the deep, resonant rumble of a car engine coming to life, signaling the start of a journey. The car, identified as Car 4, sits idly for a moment, its engine’s purr serving as the only sound breaking the silence. Suddenly, the car's engine roars louder, and the vehicle begins to move. The sound of tires crunching on gravel is heard as it slowly starts to pull away. The car's acceleration gradually increases, the engine's volume and pitch rising in sync with the car's speed. The soft whir of the car's systems and the increasing distance creates an echoey effect, adding to the sense of departure. The car's engine noise begins to fade, indicating its departure, and the soundscape ends with the faint echo of the car's engine, now far in the distance. All these sounds paint a vivid picture of Car 4's departure.
