Technology & Development

In-wheel motor

This is technology for inserting motors inside the vehicle wheels.
The technology has been made feasible by developing a compact, high-efficiency motor.
The main advantages are the high energy efficiency, large usable space in the vehicle body, and highly simple vehicle structure.
While there have been concerns that this design, with the large weight under the suspension springs, would result in poorer riding comfort, demonstration tests have shown this not to be the case.

All Wheel Independent Control

All Wheel Independent Control

The in-wheel motor controls the torque of each wheel independently, and controls the maximum frictional force between each wheel and the road surface on any road surface.
This greatly improves driving safety, stability and comfort.
