Another possible definition of efficiency is a system that works only when it is needed, and then does so in a particularly effective way.
This was the guiding principle for our engineers in the development of the electromechanical power steering. Statis- tics show that a car drives in a straight line 90% of the time. Unlike conventional hydraulic pumps, the electric motor uses energy only when the steering wheel is actually turned. The absence of hydraulic fluid also makes the system more beneficial to the environment.
As far as the other 10% is concerned, we’re optimally prepared as the steering system is typically Porsche. It features a variable steering ratio and responds sensitively and directly at the same time as providing customary agility, a high level of comfort and precisely selected feedback from the road. Our definition of efficient.
Power steering Plus, the comfort-enhancing power steering system, is available as an option for the 911 Carrera models. At high speeds, the steering is as firm as possible, ensuring maximum precision whilst steer- ing comfort remains as high. At low speeds, the steering ratio of Power steering Plus adjusts for much easier manoeuvring and parking.
