Follow the curve at Williams
Valtteri Bottas’ Williams FW37 was fitted with a revised front wing at Budapest, which draws some inspiration from the similar design introduced by runaway championship leaders Mercedes at Shanghai this year. Prior to Williams, Ferrari had already came up with its own interpretation of the concept at Silverstone.
The goal is to compartmentalise more clearly the two main functions of the wing. The arches on the outer section are now more pronounced and create a sort of reverse funnel that sits right in front of the tyres (compare yellow lines). Although this helps generate more downforce, the primary purpose remains to create a powerful vortex around the tyre in order to divert the dirty air coming off the rotating wheels.
This is why the upper edge of the endplates – which have been extended – is more curved (compare red lines). One can also spot that the endplates features an extra winglet on each side (see white arrows).
