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 .
A new front wing was tested in Barcelona on February which has a bit larger endplates and also the space between the second flap and third flap tip has been increased by little . Small revisions may improve only by a small amount car’s performance but launching constant even minor changes in almost every race can give the car steadily significant speed . That kind of approach was followed by Renault last year especially about front wing development , a trend not surprising to see it repeated this season as well .
