Centerline Turning Radius ($R_{cl}$)
Outer Wheel Turning Radius ($R_{outer\_wheel}$)
Wall-to-Wall Turning Radius ($R_{wall}$)
Centerline Turning Radius: The radius of the circle traced by the center point of the rear axle.
Outer Wheel Turning Radius: The radius of the circle traced by the outermost front wheel. This approximates the “curb-to-curb” radius.
Wall-to-Wall Turning Radius: The radius of the circle traced by the absolute outermost point of the vehicle (e.g., front corner of the bumper) during the turn.
