Toyota TF108 - bridge wing slits
In Belgium, the TF108's bridge wing featured very long slits (see arrow and inset). Although Toyota did introduce this development briefly during a practice session ahead of July's German Grand Prix, this was the first time the team ran the feature for an entire race weekend. The slits are designed to generate a suction effect that helps to boost the efficiency of the front wing. But is unlikely Toyota will be run this development at the forthcoming Monza event due to the Italian track's unique layout.
