Ferrari SF70H front wing detail 1 / 29 Photo by: Mark Sutton A great shot of the newer specification front wing from beneath shows the level of detail that goes into guiding the airflow to improve the pressure field. The shape and thickness of the under-wing strakes change in accordance with the shape of the mainplane they’re connected to and in line with the transition of the slot in front of the outer three.

Sahara Force India VJM10 front wing detail 8 / 29 Photo by: Mark Sutton The close-up of the VJM10’s front wing shows the level of complexity involved in shaping the airflow ahead of the front tyre. The designers have completely compartmentalised the outer section, creating an exaggerated tunnel in order to deal with tyre wake. Note that none of the outer sections of the wing have been painted either.

Renault Sport F1 Team RS17 detail 11 / 29 Photo by: Giorgio Piola Renault introduced these bargeboards a few races ago, albeit not racing them on their first arrival. They include a secondary pre-bargeboard, stubby vertical dividing vanes between the primary pre-bargeboard and main bargeboard's footplate and revised louvres in the footplate.

Williams FW40 steering wheel detail 19 / 29 Photo by: Giorgio Piola The clutch paddles on Felipe Massa’s car which, much like the ones already utilised by Mercedes and Ferrari, feature a mechanism that improve the driver's relationship with the paddle. In this case a pincer-style arrangement is favoured, rather than the enclosed version used by the aforementioned.
