The name "Sassou" is a Japanese term that means having a positive state of mind, of looking ahead with optimism to the future.. It is an advanced interpretation of Mazda stylishness that employs the latest in aerodynamic techniques that visually hints at the agility and fun-to-drive attributes so typical of the brand.
The hidden features are based on the "Shoji" principle.
Shoji screens are thin Japanese doors made of ricepaper that allow you to see the outline of what is behind without seeing the details.
This concept has attributes that are hidden within the body and are suddenly revealed by an illumination system to create a surprising effect.

On the inside is a high-tech, interactive interior concept reflecting the lifestyle of young people. It uses a USB stick as a key and an interface port for programming the hard disc drive conceived for the concept.
It also features a "morphing" back seating system that uses compressed air. This provides center seating for one, side seating for two by changing the seat configuration. It also has "flat-fold" seating which offers storage practicality for carrying larger items.

Combined with aerodynamic techniques to lower drag, the Mazda SASSOU design concept indicates the potential of the Mazda B-car to meet strict European CO2 regulations in the future. Mounted with a three cylinder 1.0-liter DISI turbo gasoline engine and idling stop feature that automatically shut down the engine to prevent idling, it is conceived as a lightweight, fuel-efficient, urban vehicle for young, first car buyers.
