Purpose of the System

The roll over protection system (RPS) is a passive safety system that is designed to deploy only if the vehicle is in danger of rolling over, to afford vehicle occupants additional protection. In addition to the reinforcing tube integrated in the windshield frame, RPS ensures that all the rear passengers are provided with necessary head clearance should the car roll over.

The system is similar to the roll over protection system used on the E36iC. The electronic control module for roll over detection and deployment remains the same as on the E36iC. However, the system has been redesigned in terms of function, solidity and safety.
