Variable Sports Steering

Do AU f30's coming with VSS ? When I checked my VIN i only saw HYDRO STEERING-SERVOTRONIC. I think it's an option.

What will will be missing!

Ok, so this is VSS in a nutshell:

Optional Variable Sports Steering.
Optionally a new variable-ratio steering system can be specified. Variable Sports Steering provides different steering gear ratios depending on the angle of the steering wheel, so that the new BMW 3 Series responds either more directly or more softly to the driverís inputs. This reduces the number of steering wheel rotations required for bigger turns by up to 25 per cent and makes for easier, more convenient parking and turning since less effort is required from the driver. Also, the handling is sharper in general, for example when very sudden evasive action is called for. At smaller steering angles between zero and 100 degrees, on the other hand, the Sedan provides high standards of track-holding and straightline stability, and offers very precise response to steering changes. The variable-ratio steering is a purely mechanical system based on a variable-ratio steering rack.

This is the standard steering:

The new BMW 3 Series is fitted with the electromechanical power steering system EPS (Electronic Power Steering), which uses an electric motor to provide steering assistance, with no concessions on the sporty steering characteristics for which this sedan is noted. EPS only operates when steering assistance is actually required: no electrical power is consumed during straightline driving or steady-state cornering. That is what differentiates electromechanical steering from hydraulic systems, which use power and therefore fuel even when not providing steering assistance. Highlights of this system include not only high efficiency but also low weight, high steering precision with good feedback, and comfort-enhancing self-centering and anti- roll characteristics. The BMW 335i and 328i are both equipped as standard with the Servotronic function for speed-sensitive power assistance.


Hope this helps.

the Americans that did not choose VSS are plagued with the vibrating steering wheel while driving according to their massive forum post
