In automotive terms, a diffuser is a shaped section of the car’s underbody, which improves the vehicle’s aerodynamic properties. This happens by enhancing the transition between the high-velocity airflow underneath the car and the freestream airflow of the ambient atmosphere. In simpler terms, the purpose of a rear diffuser is to reduce air turbulence as your car drives at high speeds.

By decreasing drag, rear diffusers make your car more stable at high speeds and reduce the amount of wind resistance it must overcome. Less wind resistance means that your vehicle will be able to utilize its existing horsepower and torque more efficiently. A rear diffuser also adds style to your car and helps it stand out from the crowd. If you have a rear wing on your car, it also affects the diffuser. When the rear wing is mounted low and close to the diffuser, the low pressure under the wing helps suck air through the diffuser.

As the front of a vehicle slows down the air without a diffuser, this is the ideal place to install an inlet. A splitter is commonly used and serves to increase the amount of downforce (lift inverted) at the front of the car. The airstream is brought to stagnation above the splitter by an air dam, which results in an area of high pressure. Below the splitter, the air is redirected away from the stagnation zone and accelerated, causing the pressure to drop. The decrease in pressure in combination with the high pressure over the splitter area creates downforce. Consequently, the larger the area of the splitter, the more downforce is generated.
