"Active steering" describes a type of power electric variable gear ratio power steering technology introduced by BMW in 2003 first appearing on the redesigned 5 Series which varies the degree that the wheels turn in response to the steering wheel. At lower speeds, this technology reduces the amount that the steering wheel must be turned – improving performance in situations such as parking and other urban area traffic maneuvers. At higher speeds, the performance is such that the normal increased responsiveness from speed is avoided and it provides improved directional stability.
