The adjustable front diffuser is attached to the underbody in the front section and, together with the stationary rear wing, optimises the vehicle's aerodynamics. The extended position of the front diffuser is not permitted for normal road operation. It may be used for racing mode only on dedicated race circuits, not on public roads. The extended front diffuser changes the pressure distribution across the underbody and thus increases the power output to the maximum level.

The front diffuser can be fully extended for racetrack mode and for cleaning More.
