简略说 Servotronic 之上，能够对标的目的盘转角做出反映（尤为是静止/剧烈驾驶时），听说是能够冲破速度和转向比之间对应瓜葛的限度，进步不乱性和平安性。我问过几个宝马车主，有 VSS 都说不清详细是甚么，说标的目的盘按照速度助力变动那是 Servotronic ...
从宝马中国抄来
可变静止型转向零碎
带Servotronic助力转向的可变静止型转向零碎在转向时确保了间接、灵敏且省力的驾驶格调。它能对标的目的盘转角间接作出反映，而不受各转向比确当前速度的影响。
这增加了大角度转向时所需的转向静止，从而明显进步了急转弯、沿窄路行驶或在静止驾驶格调下忽然转向时的灵敏性和操控性。另外，它还可进步驻车、转向和操控时的温馨性。关于较小转向角而言，零碎可以提供卓着的标的目的不乱性和高度的转向精准性。
Variable Sport Steering
The variable sport steering with Servotronic creates a direct and agile steering response and ensures less physical effort is required to turn the wheel. It reacts to the angle of the steering wheel independently from the current speed with various steering ratios. This reduces the steering movement required when steering at particularly large angles. It features speed-dependent, variable power steering. This significantly increases agility and improves handling when driving dynamically through sharp bends and corners, or when swerving to avoid obstacles. It also makes parking, turning and manoeuvring easier. For small steering angles, the system provides excellent directional stability and a very high degree of steering precision.
然而 spec guide 里这样写，觉得就是 servotronic 是一个颇有玄机的配置，可能就两三百，能加就加之吧，省得后悔。

Variable Sport Steering, continuously adjusts the steering force to suit the changing driving situation. Steering ratio is constantly adjusted depending on the steering movement, consequently reducing steering effort
给加点分吧，比来给他人加分加多了，分都没了 |
