Lotus Renault R31 – One more diffuser upgrade in Malaysia


   In Malaysia a metal joint was placed in the centre of the slotted tab to secure its stiffness  . Excessive vibrations of an element ruins its aerodynamic or mechanic effectiveness and  can even  cause it to crack in some occasions .

Lotus Renault R31 – More diffuser revisions in Australia


    Melbourne

  The diffuser was again revised in Australia despite the latest upgrade at Barcelona test ,  having now a new slotted tab under the crash structure to let air bleed through . The pioneer of the slotted tab feature is credited to Toro Rosso and Renault is another team ( along with Red Bull and  Mc Laren  ) to copy this idea .

Lotus Renault R31 – Another new version of the front wing was launched in Sepang


Renault seems to follow the same frenzy front wing development path  like it did last season and launched a new front wing iteration in Sepang . The wing may had new endplates but the flaps remained though unchanged .  The revisions are spotted on the front part of the endplate body which is now consisted of a single element instead of two with its base to be inclined outwards creating a large gap between its inner surface and the double profiled mini wing . The horizontal winglet  is also gone while the outer low height vertical fence is new and features a deep cut on its lower rear part . All the changes focus to reduce turbulence around the outer front tyre surface .
