The size and dimensions of Formula One cars are tightly
controlled by the regulations. They must be no more than 180cm wide. The
length and height of the car are effectively governed by other specific
For example, bodywork ahead of the rear wheel centre
line must be a maximum of 140cm wide. Bodywork behind it must be no
more than 100cm wide. Front and rear overhangs are limited to 120cm and
60cm respectively from the wheel centre lines.
regulations mean that the teams inevitably end up with very similarly
sized cars. A typical car will be in the region of 4635mm long, 1800mm
wide and 950mm high.
With the exception of the rear wing (see
below), moveable bodywork is not allowed. Furthermore, any system,
device or procedure which uses driver movement as a means of altering
the aerodynamic characteristics of the car's bodywork is prohibited,
effectively outlawing the F-ducts used in 2010.
From 2011, cars
may be equipped with moveable rear wings which allow the driver to
control the wing's angle of incidence (within specified limits) from the
cockpit. However, during the race the system is electronically governed
and is only available when a driver is less than one second behind
another car at pre-determined points on the track. The system is then
deactivated once the driver brakes. In combination with KERS, the aim is
to boost overtaking.
