Practically speaking, the design is also meant to improve aerodynamics and, in turn, reduce the amount of energy wasted pushing a big chunk of steel through the air.

Aerodynamic performance with a drag coefficient of 0.25 and zero lift

The design team sought to achieve an extremely high level of aerodynamic performance through a combination of design and technologies. A bird's-eye view of the Mazda Taiki body shows how much its width is tapered from front to rear. From the side, one sees the smooth line of the flat underside kick up dramatically at the rear of the body. Validating the designer's wish to visually capture the motion of flowing air, wind tunnel testing proved the excellent aerodynamic performance inherent in the design.

The distinctive shape around the rear wheels, which channels air flowing back from the front fender through a 'tunnel' formed between the body and rear fender, also proved effective in creating down-force.

The already high aerodynamic potential of the original form was then fine tuned, the end result being an excellent drag coefficient of 0.25 and zero lift.
