Purpose and Compatibility with BMW

BMW 5 Series E60/E61 and BMW 6 Series E63/E64 utilize an advanced steering system based on a hydraulic rack with Servotronic power steering force adjustment. The described steering rack has been developed as an original component, intended to work with the factory steering column, power steering pump, and vehicle electronics.

Thanks to the dedicated design, the rack maintains the correct suspension geometry, which translates to:

• confident straight-line stability at higher speeds,
• smooth maneuvering during parking,
• consistent steering feel in line with BMW's character.

Hydraulic and Servotronic Technology

The hydraulic power steering rack with Servotronic function combines classic hydraulic assistance with electronic control of the assistance force. The system adjusts the steering wheel resistance to the current vehicle speed, allowing for:

This solution supports both everyday driving comfort and the precise handling for which BMW 5 and 6 Series models are known.
