Active Lean system
A tight turning radius combined with a narrow, tall body should make the iRoad prone to overturning, but Toyota has equipped the EV with a gyro-controlled Active Lean system. When cornering hard, the iRoad's suspension leans the body into the turn, much like a motorcyclist would, increasing grip as the front wheels are driven into the road by centripetal force. The Active Lean system also works when the vehicle driving on cambered surfaces, keeping the body upright even when not cornering.
