The FW32 features multiple sets of winglets placed at the rear wheels internal zone . From their attack angle i assume that their role is to add down force directly to the rear axle . Those winglets could be regarded as movable aero parts but are considered by rules to be part of the rear braking system !
The rear bodywork of the car was slightly modified at Bahrain and specially the exhausts zone . At hot Sakhir’s weather conditions asymmetric exhaust outlets were used with the left one to be larger to satisfy the car cooling needs .
On the contrary at cooler Melbourne a symmetric and simpler configuration was used to reduce drag production .
At Malaysia , China and Spain the team reverted back to the asymmetric exhaust outlets configuration already used at Sakhir
Bahrain , Sepang , Sinopec , Catalunya
The front wing used at Spain had the rear vertical part of the endplate revised and furthermore there was an additional small fin ( acting as a vortex generator ) at the rear endplate top section to improve airflow management close to the front wheels.
The FW32 is equipped with a triple profiled front wing. This wing is not totally new but rather a heavily modified FW31 ‘s late 2009 season wing with revised endplates and twin upper cascade winglets (1) and additional high vertical inner endplates (2) .
Williams abandoned the front snow plough project under the nose , which was introduced last year and it is now used by Mc Laren MP4/25 , due to the adaptation of the 2009’s Brawn BGP001 splitter design . This splitter , which creates a kind of venturi effect under the car , is inclined downwards to the rear to accelerate the airflow under the car in an attempt to decrease further the under chassis pressure . An evolutionary step of the splitter design was introduced at Bahrain and specially the new design features a large middle slot (1) to allow part of the air to flow over the floor and towards the inner bargeboard-car body zone .
It is worthy of mentioning that this part of the floor is an ideal place for mechanics to house blocks of heavy metal as ballast (2)
The Williams FW32 nose camera winglets position , possibly inspired by the last year Red Bull RB5 , is exactly at the nose tip in such a way that a plane is formed . The nose cone , which resembles now to the hammerhead shark’s head , is really thin and its under side is also very flat , like the hammerhead shark ‘s under front body . The hammerhead shark’s strange plane head shape is to increase its capability for picking up electrical signals but the FW32 one is to increase airflow under the nose and to decrease front end pitch sensitivity .
The oval hole at the nose cone tip helps to cool the nose housed electronics . A honecomb style protective frame covers the inlet to prevent small hazardous fragments ( like little rocks ) from entering in .
At the top of the nose a U shaped structure is formed to channel air more efficiently over the nose (1) resembling to Red Bull’s design but in Williams case this channel is less deep . Finally there is a pitot tube (2) for measuring the car’s speed .
