A diffuser element for the underside of a vehicle comprises in longitudinal vertical section, in sequence from front to rear, a first smoothly and monotonically rising panel, and a second panel, and a gap between the first and second panels, wherein the edge of the second panel adjacent the gap comprises a substantially flat planar section which is offset from and below the plane of the first panel ahead of the gap. This type of gap in the diffuser serves to bleed off the boundary layer from the airflow passing through the diffuser, thus enhancing its effectiveness and improving the downforce that is generated as a result. The gap is preferably located in the front half of the diffuser and can form the entrance to a duct leading to an exit on the rear of the vehicle.
