Which four wheel steering benefit appears at low speed?

  • A.A tighter turning circle from opposite phase rear steering
  • B.Improved stability, which is obtained by steering the rear wheels in the same direction as the front wheels
  • C.Reduced tyre wear
  • D.A lighter steering effort, since the rear wheels contribute to the turning and reduce the load upon the front tyres

Answer: A

Steering the rear wheels opposite to the front at parking speed shortens the effective wheelbase and tightens the circle considerably. Same phase steering at high speed improves lane change stability instead. The system reverses phase at a threshold speed. Tracing the requirement back to the physical constraint that produces it makes the answer follow. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb.
