Toyota TF108 - nose winglets
As part of their aero update for Barcelona, Toyota included two wider-than-normal winglets on either side of the TF108's nosecone (yellow arrow and inset). In principle, these are similar to the 'elephant ear' nose wings adopted by Honda. Rather than increasing the overall amount of downforce load, they direct the airflow towards the sidepod inlets and the car's rear end more effectively. It is a solution that works particularly well on tracks like the Circuit de Catalunya, with long straights and fast corners but, while front-end stability was markedly improved, both Toyota drivers decided to revert to the standard solution for the race itself.
