This is from the M5 section (page 39) of BMW's media information kit from the Frankfurt show:
Hydraulic rack and pinion steering with variable transmission, which combines precise directional stability with reduced steering effort when manoeuvring, is an M-specific feature. Using independently configured M Servotronic, the characteristics of the speed-dependent power steering can be individually set via three accessible characteristic maps.
See the whole information kit attached.
