Aerodynamic downforce is generated by an automobile diffuser located on the aft section of a motor vehicle's underbody. The upsweeping inclination of the diffuser ramp wall enables the expansion of airflow traveling through the diffuser to induce suction underneath the motor vehicle—thereby enhancing traction between the tires and road surface. However, moving (or rolling) the diffuser ramp wall in the airflow direction further increases suction and airflow speed underneath the vehicle and through the diffuser. As a result, downforce in-turn is enhanced.
