Sauber C33 – fully “decorated” car after Jerez test


Sauber C33 2014 after jerez test upgrades

 

 

   The car tested in Jerez (pre session test) was stripped of significant aerodynamic elements like sidepod panels and nose vanes because the team focused solely on improving and checking mechanical reliability instead of pushing for the ultimate time. This changed soon after the first test as wide vertical panels attached on sidepods alongside with lateral flow conditioners and skirts added under the nose where the suspension wishbones meet the chassis.

    Insufficient rear downforce production was noticeable on Sauber and thus team soon pushed to develop new rear wing designs towards downforce increase .

     The initial wing version seen in Jerez had two distinctive V cuts on the trailing edge of the movable upper element where the two flap fasteners exist, while the main flap had a slopping downwards profile close to the endplates to benefit as possible from the clean airstream coming unblocked by the main airbox body. Such main flap design philosophy springs its origin from old Renault team (now renamed Lotus) back in 2006 .

     A  new version put under test in Bahrain two weeks after which had a wider main flap and three fasteners this time. The upper element was also new because it featured only one  V cut in its middle section now. Additionally a mini plane made its appearance above the rear structure.

    For Melbourne the Bahraini spec modified  further, regaining back the two flap fasteners structure design  but loosing the V cut.  The mini plane also removed .

PS=  The V cut bleeds pressure from the wing decreasing drag with small negative impact on downforce production

   After  Jerez test, Sauber tried a new front wing with a more boxy upper flap, revised  main lower flap with wider slot also colored differently (more white color on its surface) , relocated cascade pillar and a less ducted endplate with new terminal body.  The new wing  retained for Melbourne .
