BMW has
developed Active Front Steering (AFS) that maintains a
mechanical link between the front wheels and the steering wheel.
AFS varies the steering transmission ratio electronically in
direct relation to the style and speed of driving and road
conditions. Under normal road conditions at low and medium speeds,
the steering becomes more direct, requiring less steering effort of
the driver, increasing the car’s agility in city traffic or when
parking. At high speeds the steering becomes less direct offering
improved directional stability. When cornering at high speeds, or
when undertaking sudden movements, the steering stiffens up by
monitoring increases in the yaw rate.
AFS
works hand-in-hand with Dynamic Stability Control (DSC) by
monitoring the yaw rate and changing the steering angle accordingly.
This reduces the number of DSC interventions, providing more control
to the driver and increased comfort for the passengers.
Optional
Dynamic Drive active suspension filters out bumps and
suppresses virtually all body roll on cornering through the presence
of two active anti-roll bars physically integrated into the front
and rear axles. This further enhances agility and stability. Up to
80% of a car’s normal body roll in sharp bends is removed by Dynamic
Drive, which also has active safety implications since directional
stability is enhanced when taking emergency evasive actions.
Optional
Active Cruise Control, first introduced on the new 7 series,
automatically controls the distance to the car in front. This
radar-based system is specially designed for highway driving, which
makes it easy to maintain a safe and comfortable distance from the
car in front.
The
driver selects a comfortable distance to cruise behind other
vehicles and the system automatically cuts power if the distance is
reduced. Cruise control is still engaged, however, and as soon as
the selected distance is available again, the car automatically
speeds up to the desired cruising speed.
Better Lighting
Active
safety measures on the new 5 series include
Adaptive Headlights
and Brake Force Display. These safety devices reduce the risk of an
accident both front and rear.
Optional
adaptive bi-xenon headlights swivel by up to 15 degrees left and
right depending on the car’s steering angle, yaw rate and road speed
in order to illuminate more of the road ahead when driving through a
bend.
Brake
Force Display enlarges the brake light area when the driver
brakes sharply. When the driver applies the brakes hard, or upon
activation of the ABS, the rear taillights join the brakelights at
the same intensity to warn the vehicles behind that hard braking is
taking place. This technology uses Light Emitting Diode (LED)
technology and offers an extra split second for the driver behind to
react to heavy braking ahead.
Better Information
The new
5 series will also feature the option of a
head-up display,
which presents vital information relevant to the driver directly on
the windscreen in his/her line of vision. The driver can select what
information is displayed (road speed or navigation instructions for
example) and never has to take his/her eyes off the road. This
information is displayed in a way that does not impinge on
visibility.
The
optional head-up display makes a significant contribution to active
safety, by presenting important driving information directly in the
driver's line of vision. This new system even allows the driver to
select which information will appear on the windshield, for example
speed or navigation instructions. Passenger comfort is enhanced by
the new automatic climate control system, which features evaporation
temperature control. The rear seating area has grown from the
previous model, and trunk area is significantly expanded as well.
Better Air Conditioning
New
automatic adaptive air conditioning maintains humidity within
the car to counteract the normal drying effect of traditional
air-conditioning units and will be standard equipment on all models.
