2) Active Steering - an option, according to the S. African product catalog. The currrent iteration in the 335 varies steering ratio with speed, such that at lower speeds a slight turn of the wheel translates to a large turn of the car. "Active Steering adjusts the steering ratio in relation to vehicle speed. At lower to medium speeds, the steering is more direct; at higher speeds, the steering provides greater directional stability." (source BMWUSA website)

can you comment on whether either of these options were equipped on your test vehicle and whether you feel that equipping/unequipping these options would improve steering feel?
There's was no active steering on the cars, just the usual servotronic system (as fitted to most BMWs).

With the M Settings within iDrive it was possible to alter the steering assistance from Normal to Sport, which is pretty similar to what was available on the E39 M5 (i.e. it increased the weighting of the steering , but did not change its gearing).
