BMW 5 Series Gran Turismo
Classic GT substance in contemporary SAV flavour
(7/9 >>>>)

  Lights and Visibility

Standard features include the fog lamps and the light sensor which, as a function of ambient brightness, automatically activates the low-beam headlights when required.

Cornering light function (photo with the 7 Series).

With the optional bi-xenon headlights, the LED units in the corona rings may be operated in one of two performance stages. Dimmed to approximately 10 per cent of their full output, they serve as positioning lights. Operating with full power, they provide the daytime light function in the familiar BMW look.

The optional Adaptive Headlights can illuminate the road following curves and winding stretches of road. The headlights swivel to the side in the same way as the steering, also following the yaw rate and the speed of the car. The Bending Lights function (photo above) is integrated in the headlights with an additional light beam switched on when taking a bend in order to illuminate the road in the direction the driver is taking.

Additionally, Adaptive Headlights provide variable light distribution on straight lines. As a function of driving speed, the system automatically enlarges the area of visibility by expanding the light beam. In the City Light mode at speeds below 50 km/h (31 mph) a wider light footprint makes it easier to detect objects on the left-hand side of the road. In the Autobahn Light mode, on the other hand, the driver's field of visibility is expanded by increasing the headlight range and intensifying illumination on the left-hand side.

Adaptive headlights prevent dazzling oncoming traffic.

Adaptive headlight range control takes the vertical contours of the road into account.

Adaptive headlight range control also takes the vertical contours of the road into account, the light beam being appropriately lowered or raised when driving across crests, through tunnels or up and down steep ramps, without dazzling oncoming traffic (photos with the 7 Series) .

Adaptive headlight range control also takes the vertical contours of the road into account, the light beam being appropriately lowered or raised when driving (above graphic, showing the system principle in the BMW 7 Series) across crests, through tunnels or up and down steep ramps, without dazzling oncoming traffic. As soon as the driver switches on the fog lamps, variable light distribution in the speed range up to 70 km/h (43 mph) provides a broader distribution of light and brightens up the area directly in front of the car. At higher speeds, the headlight range is also increased over and above the broader light distribution.

The optional High-Beam Assistant automatically switches the high-beam headlights on and off, depending on the distance from vehicles coming the other way or driving ahead of the car.

Another standard feature to enhance visibility is the rain sensor which registers the intensity of precipitation to automatically adjust the speed of the screenwipers

  Night vision

The optional night vision system provides detection of persons with a corresponding warning function.

Night Vision with pedestrian recognition.

Night Vision with pedestrian recognition.

The system is based on a thermal imaging camera delivering a moving video picture in which the driver can see people, animals and other objects also outside of the headlight beam through high-resolution presentation in the Control Display.

The system is being supplemented for the first time by a precise recognition of persons, with video data being analysed by a control unit which recognises pedestrian shapes and then highlights any person detected with a yellow colour in the video image. If the system see that a specific person is possibly at risk, the driver will receive an additional warning.

  Driver assistance

The driver assistance systems provided by the BMW ConnectedDrive include the High-Beam Assistant, Lane Change Warning, Lane Departure Warning, Speed Limit Info, the new generation of BMW Night Vision to detect humans shapes while driving at night, in addition to the standard cruise control with a brake function, or the optional Active Cruise Control with Stop & Go.

  Cruise Control+BF

The standard Cruise control with a brake function acts on engine management, the choice of gears and the brakes to consistently maintain the speed chosen by the driver.

The system permanently registers lateral acceleration of the vehicle and, where necessary, helps to reduce road speed by intervening in engine management and the brakes to enhance comfort in bends for example. It also helps driving downhill in a smooth and controlled process also when towing a trailer if necessary by intervening in the brakes.

  Active Cruise Control
  & Stop & Go function

The optional Active Cruise Control with Stop & Go includes an automatic distance control function allowing the driver to cruise in flowing autobahn or country road traffic, or to maintain an appropriate distance from the vehicle ahead in stop-and-go traffic at minimum speed.

The driver retains his responsibility at the wheel, being required, for example after a short stop of more than three seconds, to re-accelerate the car either by briefly pressing down the brake pedal or by pressing the Resume button. Even if Active Cruise Control with Stop & Go is active, the driver can modify the speed of the car at any time by giving gas or applying the brakes.

Active Cruise Control with Stop & Go uses the latest generation of radar sensors. As soon as the car remains below the minimum distance from the vehicle ahead set by the driver, the system adjusts the speed of the car by intervening in drivetrain management and building up brake pressure in accordance with current requirements. The maximum deceleration allowed by Active Cruise Control with Stop & Go is 4 metres/sec2 and is limited at higher speeds to a more comfortable 2.5 metres/sec2.

If the car ahead is braking all-out, the driver is notified by optical and acoustic signals. At the same time the response thresholds for the Brake Assistant are lowered and the Brake Standby function of DSC Dynamic Stability Control is activated.

  Lane Change Warn.

Lane Change Warning: side mirror view.

Lane Change Warning: a signal by an LED flashing on and off on the base of the exterior mirror housing and a discreet vibration on the steering wheel.

The optional Lane Change Warning system uses radar sensors at the back of the car to monitor traffic conditions on the adjacent lanes and in the driver's blind angle. If the turning indicator is activated, showing an intention to change lanes, while another vehicle is in the way, the driver will receive a warning signal by an LED flashing on and off on the base of the exterior mirror housing. He / she will also be warned by a discreet vibration on the steering wheel that there is another vehicle in the vicinity.

  Lane Depart. Warn.

Lane Departure Warning, graphic.

Lane Departure Warning  (see opposite details).

On the other hand, the also optional Lane Departure Warning system is made up of a camera fitted on the windscreen near the interior mirror, a control unit for comparing data, and a signal actuator causing the steering wheel to vibrate, urging the driver to correct the steering. The camera monitors road marks on at least one side of the lane, as well as their distance from the car and the edges of the road. It covers about 50 metres (164) feet ahead and may also be used at night as soon as the headlights are switched on.

  Speed Limit Info.

Speed Limit Info on the head-up display.

Speed Limit Info.

With the optional navigation system Professional, the also optional Speed Limit Info keeps the driver aware of the speed limit on the current route. The camera fitted near the interior mirror permanently monitors speed signs at the side of the road as well as variable signs overhead a motorway, comparing the data observed in this way with the data already saved in the navigation system. The speed limit is then shown in the instrument cluster.
