I can assure you UK spec X1 cars do not come with Servotronic steering, It's not available in this country even as an Option, I cant understand why?
Servotronic power steering in the BMW X1.
The
optional Servotronic power steering in the BMW X1 xDrive20d and xDrive23d ensures optimal steering responsiveness in any situation. Servotronic adjusts the amount of steering assistance to suit the current speed, enhancing driver comfort by lowering the effort needed to turn the steering wheel. It provides light-footed responsiveness and agility at higher speeds and effortless agility when parking or in narrow, angular curves.
