Driver drinking system layout 21 August 2005
In the Turkish heat (which in the end was not as severe as expected) it is crucial that a driver can easily take on fluids. The usual system to provide this has three elements. The drink reservoir is placed low on the side of the cockpit, so as to prevent it raising the car's centre of gravity. It usually contains around two litres of fluid (which means two kilos of extra weight at the start of the race). A pump, activated by the driver via a steering-wheel switch, sucks the liquid through a tube and to the driver's mouthpiece inside his helmet.
