Objective testing of steering performance is typically the most repeatable and used for tire, damper and suspension development or competitive vehicle benchmarking programs. Testing includes low-g sine-steer, swept steer, parking efforts, frequency response and returnability tests. Maneuvers are performed at various predetermined speeds or specific speeds requested by the customer or dictated by the vehicle.
