text: The title of Formula One World Champion Constructor is awarded to the car `` make '' that has scored the most points during the course of the season , where a car 's make takes into account both engine and chassis . Hence , if a car 's chassis and engine constructor are the same entity ( e.g. Ferrari , Toyota , BRM etc. ) then the make is simply the name of that one constructor .
simplified: If a car 's chassis and engine are made by the same entity , then the constructor is the car make .
