One 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 electro- mechanical steering system. Whereas a conventional hydraulically assisted steering system draws engine power continuously, the electric motor in the electromechanical arrangement uses energy only when the steering wheel is actually turned. As a result, fuel consumption is reduced and the absence of hydraulic fluid eliminates the need for servicing, both of which also have benefits for the environment.
The Boxster concept was designed to offer outstanding cornering performance. The steering system delivers and it even improves the typical Porsche steering feel. It features a variable steering ratio and responds precisely and directly as well as providing customary agility, a high level of comfort and plenty of direct feedback from the road. Power steering Plus, the optional speed-sensitive power-steering system, minimises steering effort during manoeuvring and parking.
