Among the technologies borrowed from the smaller M model for use in the 2006 Infiniti Q45 Sport is Rear Active Steering. When heading into a turn, the rear wheels turn slightly (up to one degree) in the opposite direction of the front wheels to help the car take a proper set in the turn. When exiting a corner or making a lane change, the rear wheels turn slightly (again, up to one degree) in the same direction as the front wheels to help accelerate in the intended direction.
