MP4/25 – diffuser revision at Melbourne due to FIA request


 

 

       Following a rule ( article 3.12.7. ) clarification from FIA stewards at Bahrain  Mc Laren  at Melbourne had to decrease the motor access hole ( apart from the front wing’s sharp endplates  ) , located at the central zone    .

 

FIA REGULATIONS  ABOUT MOTOR ACCESS HOLE

article 3.12.7

No bodywork which is visible from beneath the car and which lies between the rear wheel centre line and a point 350mm rearward of it may be more than 175mm above the reference plane. Any intersection of the surfaces in this area with a lateral or longitudinal vertical plane should form one continuous line which is visible from beneath the car. A single break in the surface is permitted solely to allow the minimum required access for the device referred to in Article 5.15.

         In plain words Mc Laren run a larger than needed hole to access the engine starter  to make its diffuser act partially as a triple decked instead of two-decked , gaining extra downforce .
