Hispania Racing Team F111 – diffuser details

    The F111 follows also the trend of exhaust blown diffuser having the exhaust pipelines ending close to the rear crash structure . There is a pair of vertical fences (in yellow) twisted outwards  in either side section of the diffuser pattern and also a high tab fence across the diffuser roof extending even to its vertical sides to improve air sanction. Of course the tab partially blocks the hot exhaust emissions preventing a stronger blending of them with the air coming from under the floor, a situation by passed by some teams, like Red Bull, Lotus Renault and Toro Rosso for example, using a slotted tab fence .
