BMW Sauber F1.07 - new front wing 11 May 2007
The BMW sports extensive changes to both front and rear wings in Barcelona. The front has a completely new main profile - highly curved with a squared spoon shape in the centre (red arrow - previous design in red circle) and a front lip that protrudes slightly upwards. The new design dramatically increases the quantity of airflow passing over the main profile and between the two flaps.And the taller mounting pillars mean the distance between the nose and the wing is now greater, reducing disruption to the airflow. The changes not only raise downforce, but also make for sharper front-end handling, and increase the car's sensitivity to set-up variations - just small changes to the flap angle will now dramatically alter the front-end's behaviour.
