In the end, their two cars qualified and raced with different specifications of turning vanes under the front part of the chassis.
Both drivers tested the new one on Friday, but only Kvyat qualified and raced it. This version is quite a similar solution to that on the Toro Rosso and is designed to channel airflow under the chassis to the rear of the floor where most of the downforce on an F1 car is generated.
There are three elements to the new design. Ricciardo used the standard configuration (inset) with only two elements and a curved end to the turning vane.
