The Mazda Koshi Concept is the electric and autonomous car of the future inspired by the imperial bunk beds of medieval Japan

The problem of the high density of population and cars in cities could have an answer in the Mazda Koshi Concept . The Koshi is both an autonomous car and a railway capsule, it is also a vehicle inspired by the traditional Japanese bunk beds.

The cities are increasingly populated and the lack of space, both in homes and on the streets, is beginning to be a real problem in some large capitals. Japan has been living with this problem for decades (most of the population is concentrated in only 35% of the territory).

In terms of individual mobility it is an even bigger challenge. Where do we park the car? In many Japanese municipalities, without an assigned parking space, the motorist cannot register his car, hence the origin of kei cars, very small cars, and exempt from parking spaces. And in the end, are so many cars necessary to transport one or two people?

Mazda Koshi Concept

The answer from Dong Yi, a student at MATD (Masters of Arts in Transportation Design) at the prestigious art and design school in Pforzheim (Germany), is clearly not. His answer is that of a multipurpose, modular vehicle that would take us door to door and that reduces the space it occupies on the streets almost by half. His answer is the Mazda Koshi Concept.

This Mazda Koshi Concept is Dong Yi’s end of career work. And instead of designing an umpteenth supercar (a very rewarding, but obvious exercise), a challenge has been posed, that of providing a mobility solution. The true value of design is that it provides a solution to a problem, responds to a need and does it in style. It is not just art.

The 21st century bunk bed

The Mazda Koshi Concept is not a vehicle itself, but a module or capsule that is integrated into the home, in the city and even in the public transport network. And clearly Japanese inspiration. Yi Dong’s idea is to adapt the traditional Japanese bunk beds to the modern era. Which partly explains the upper beam, the side curtains and even the jade green color, eminently Asian in its connotation.

The Koshi is designed to operate within a vertical space, by rails and integrated lifting systems in buildings and cities. A bit like the way Japan has its cities configured. If stored in a vertical garage or a dedicated floor area, a crane attaches to the arms and takes you where you need it to pick you up. From there, you can continue your journey along the rail interconnection or enter car mode.

The auto mode is obtained by adding two kinds of electric scooters Segway style that are not being used individually, one at each end. The Koshi is an autonomous vehicle for two people. On board, with extraordinary simplicity in design, the two passengers can play chess, go or whatever, if they wish, thanks to a board that emerges from the bunk floor.

Could it be the car of the future ? Despite needing an important infrastructure (monorails that run through the city), who knows.
