How Rally Car Works

Rally is a form of motorsport that takes place on public or private roads with modified production or specially built road-legal cars. It is distinguished by not running on a circuit, but instead in a point-to-point format in which participants and their co-drivers drive between set control points (special stages), leaving at regular intervals from one or more start points. Rallies may be won by pure speed within the stages or alternatively by driving to a predetermined ideal journey time within the stages.
