The wing used at Monza was a revised Canadian spec with twin inner triangular fences instead of one to further improve car’s underbody aerodynamic performance . The second extra one was mounted on the main plane while the first is mounted on the second plane
The under nose vanes were revised further at China , having now a more roundy lower front section to smoothen the airflow passing inside the vanes tunnel towards the rear
The additional endplate’s bulge , which houses a part of the wing activator mechanism , ( first presented at Silverstone alongside with the triple profiled wing ) was abolished at Hungary revealing that the flap activator mechanism was further revised .
The endplates featured at Hockenheim a new profile with their front bottoms only to bend outwards so as to increase the width of the channel under the wing profile and the amount of air entering under the wing in an attempt to generate more front downforce .
The car was equipped with a new set of vanes placed under the front suspension’s lower wishbone at Sakhir . The new set is directly attached onto the chassis while the older version featured two inclined pillars to hold the vanes . The pillar-less version offers a better airflow under the car as the air blocking pillars are now removed . Lastly the new set does not feature anymore the saw-tooth upper profile towards the rear like the older version which helped to reduce turbulence , probably because the new shape offers a cleaner airflow .
A new higher downforce tripled flapped wing was adopted for Silverstone with slightly revised cascade winglets . The main profile has now a W-shape in order to speed the air passing under the centre zone and closer to the endplates . Nevertheless the endplates remained unchanged . This was the 5th front wing spec since launch time .
Lastly the wing ‘s endplates feature an extra bulge revealing that the flap activator mechanism was revised also .
