Formula One cars use semi-automatic sequential gearboxes with six or seven forward gears and one reverse gear. The driver signals gear changes using paddles mounted on the back of the steering wheel and electro-hydraulics perform the actual change as well as throttle control. Clutch control is also performed electro-hydraulically except from and to a standstill when the driver must operate the clutch using a lever mounted on the back of the steering wheel.

This video clip explains the technology involved.
