The automatic clutch connects to a hydraulic motor – a replacement for a clutch pedal – and changes gear for you when in automatic mode. Carefully tuned gear ratios control how fast or slow the wheels spin. The engine produces kinetic energy which helps to rotate the wheels. You can push a lever on the gearstick to change gears or use steering wheel paddles which allow you to go up or down by pressing the ‘+’ or ‘-’ buttons.
