Active Steering on the front wheels enables the driver to manoeuvre the
car smoothly and easily at low speeds with just small movements of the
steering wheel and without crossing over his hands. At higher speeds, in turn,
the same movement of the steering wheel turns the wheel by a smaller angle
for optimum precision when steering into bends. Turning the rear wheels by
up to 2.5
o , Integral Active Steering further enhances the agility and
manoeuvrability of the car in city traffic and on winding mountain roads,
with the rear wheels turning opposite to the steering angle of the front wheels
at speeds of up to 60 km/h.
This not only reduces the turning circle by approximately 0.5 metres, but
also increases the driver’s motoring comfort by reducing the steering effort
required.
At higher speeds Integral Active Steering gives the car an extremely
comfortable and superior response when changing lanes and in bends,
with the rear wheels turning in the same direction as the front wheel,
the BMW 5 Series Sedan therefore following the course set out by the
driver precisely and smoothly in every situation. When changing direction
under dynamic driving conditions, the car is therefore able to master a high
level of lateral acceleration without the yaw rate increasing to the same extent.
This ensures a significant increase in motoring comfort, with these two
factors being kept apart.
Dynamic Drive Control: the ideal set-up for every situation.
The new BMW 5 Series Sedan sets new standards in the upper midrange
segment not only in terms of driving dynamics, but also in its driving comfort.
Right from the start the suspension technology featured as standard provides
a good balance of driving dynamics and comfort. And depending on
driving conditions as well as individual preferences, the driver may place
the emphasis on both the sporting and/or the comfort character of the
new sedan.
All this is made possible by Dynamic Drive Control which, in conjunction with
the optional Sport Automatic, Integral Active Steering and Dynamic Damper
Control or, respectively, Adaptive Drive, comes as standard on the
BMW 5 Series Sedan.
Dynamic Drive Control masterminds the progressive action of the gas pedal,
the response of the engine, the steering assistance map, the thresholds of
DSC Dynamic Stability Control and, where fitted, also the dynamic gearshift of
the automatic transmission and the control map on Dynamic Damper Control.
