Toro Rosso STR1 28 February 2006
The STR1's apparent similarities to the Red Bull RB1 have been subject of much discussion, but there are some clear differences. The lower parts of the sidepods (1) have shrunk and become more rounded, following the fashion for a reduced cross section. This helps improve the quality of airflow directed towards the rear of the car. On the engine cover, the vertical tail fin (2) is much shorter than the full-length version seen on the RB1. And on the rear wing the endplates feature a deeply-sculpted profile (3) at the back. This helps airflow to detach more quickly from the endplate, hence reducing drag.
