Correct answer
Frontal area and body shape.
Frontal area and body shape. Drag depends on frontal area and the drag coefficient, which reflects how shape and flow conditions affect motion. With the same coefficient, speed and air conditions, a larger frontal area increases drag; greater size alone does not imply a worse coefficient. Maximum engine power does not determine that coefficient.
