A splitter is commonly used to increase the amount of down force at the front of the car. The airstream is brought to stagnation above the splitter by an air dam, causing an area of high pressure. Below the splitter, the air is redirected away from the stagnation zone and is accelerated, causing the pressure to drop. This, combined with the high pressure over the splitter, creates down force. The larger the area of the splitter, the more down force is generated. In most closed-wheel race cars, the underside of the splitter smoothly integrates with the under tray, creating one large flat plane that is driven by the rear diffuser.
