Chassis Dynamics - Overview: Steering: Notes
A vehicle's steering plays a central role in the chassis and suspension. The technological innovations introduced by BMW like active steering and rear axle slip angle control, are also used in the F10. Futhermore, the steering is now implemented completely electrically with the use of EPS (Electronic Power Steering).
This system is a modified and enhanced version of the E89 Z4 EPS.
