Toro Rosso STR02 - barge board development 25 August 2007
The barge boards continue to evolve. In Turkey the front ones now feature a larger horizontal fin (1). The lower edges of the main boards have also been refined to work in conjunction with the front boards. A small vertical fence (2 - right) has been placed beside the splitter's horizontal section (or bib), creating a channel of sorts to better divert airflow under the car. And the knife-edge profile of the barge boards has gained a curved lip (2 - left) to improve the way the boundary layer of the airflow passing close to the shields is detached, thus cutting drag.
