Hydraulic steering technology is almost extinct in the modern automotive world. This type of power steering system, once widespread but now largely phased out, uses fluid pressure to assist steering. A belt running off the engine drives the power steering pump and pressurized fluid flows into a cylinder when the steering wheel turns. The result is easier steering effort, while the system still communicates road conditions through the wheel. The result is favored by car enthusiasts because it lends itself well to high-performance driving.
