When a properly tested and designed underbody diffuser is used, it creates low pressure as the diffuser chambers "expand" towards the rear of the car. This creates downforce with far less drag compared to traditional wings. Note the properly tested and designed part.

Straight from the Infiniti website...


To reduce drag under the G35 Coupe, openings are sealed, the floor pan is smoothed, and brake lines are countersunk into the chassis so as not to trap air. Diffusers create low-pressure areas that reduce lift. Hot air is drawn from the engine and cool air directed through the brakes.
