Mercedes W05 – Mini wing addition in Jerez test

 

   New W05 proved fast and reliable from the start and therefore multiple upgrades made their arrival very soon on the chassis, including a mini wing addition above the exhaust terminal pipe. Rival teams targeted on improving reliability instead, having minor interest to push for speed.

   In the absence of a beam wing in 2014 the extra winglet is attached on the rear crash structure behind and between the double supporting wing pillars.
