FIA Formula One Bahrain Grand Prix 2004
A similar feature to that already seen on the BAR 006, the FW26 sported two inner vertical fences within its rear wing. The solution provided a better management of airflow. By dividing the wing into three sections, it increased the airflow pressure in each, raising overall downforce.
A subtle change to the front aerodynamics with the introduction of a stepped plane, with a vertical profile, to the bottom of the barge boards inside the front suspension. This created a better seal between the bottom of the car and the ground, diverting airflow underneath the car more efficiently.
Toyota concentrated on improving rear-end aerodynamics with these new engine-exhaust chimneys that were lower, longer and horizontal, as on the BAR 006. Although one might imagine this solution to worsen hot-air extraction from the sidepods, it in fact proved very efficient in aiding airflow over the rear of the car.
