Ferrari F10 - 'F-duct' system 09 May 2010
In Barcelona Ferrari have introduced a full version of their 'F-duct' system. In principle, it is the same as McLaren's original design, apart from the way it is controlled by the drivers. The air streams in from one of the new side ducts on the engine cover and is then channelled into the cockpit via the electronics cable hole (white arrow). The driver can then activate the system by blocking the hole at the side of the steering wheel with the back of his left hand. As we saw from onboard footage, this can interfere with the driver adjusting the car's brake balance, which is usually carried out with the same hand. This forces the driver to race for a fraction of a second without their hand on the steering wheel.
