This invention provides an automotive power unit. A transverse baffle assembly within the fuel tank divides the fuel storage chamber into one or more first partitioned cavities along the height of the fuel tank shell. The size of each first partitioned cavity is smaller than the size of the fuel storage chamber. A longitudinal baffle, along the length of the fuel tank shell, divides the first partitioned cavities into one or more second partitioned cavities. The size of each second partitioned cavity is smaller than the size of the first partitioned cavity, thus reducing the space for gasoline movement. Simultaneously, longitudinal through-holes allow communication between different second partitioned cavities, enabling gasoline to flow between adjacent second partitioned cavities. When gasoline sloshes, it flows from one second partitioned cavity into another, reducing air bubbles generated by the impact between the gasoline and the longitudinal baffle. The flow guiding assembly provides downforce to the vehicle while simultaneously dissipating heat from the cooling system.
