An inflatable space displacement device conforms generally to the rear floor and rear seat configuration of an automobile to fill the volume of the rear passenger compartment below the level of the front seat headrests and the top of the rear seat backrest without obstructing the driver's view through the rear window. The space displacement device reduces the volume of the climate controlled airspace of the interior passenger compartment, thereby increasing the efficiency of the air conditioning and heating system, while also increasing fuel efficiency. The inflatable space displacement device may further serve as safety flotation in the event the automobile accidentally enters a body of water. The device can be fitted with a tube connected to a mouthpiece for breathing the air contained within the device in the event of an emergency. Pocket compartments are provided on the device for convenient storage and ease of driver access to articles, such as road maps, while driving.
