Two groundbreaking safety innovations will be available on BMW models this
autumn when Night Vision and High-Beam Assistant are offered for the first time.

Night Vision uses a special thermal imaging camera to 'illuminate' pedestrians,
animals or any objects emitting heat up to 300 metres ahead of the car.
Infrared technology generates a clear image of the road ahead on the iDrive
screen and the system is particularly effective on long stretches of unlit road
or motorway. Bi-Xenon headlamps already illuminate the road 150 metres ahead,
but Night Vision offers the driver a significantly longer range of vision. The
result? All round better awareness of the road ahead and safer driving.

Road safety levels can be further increased by the use of High-Beam Assistant -
a system that automatically sets the Bi-Xenon headlights to the optimum range
and brightness depending on other traffic movements. A sensor at the front of
the car detects any oncoming exterior light source, allowing the car to
automatically switch between high and low beam for the best level of
illumination. For example, the car's headlights will automatically dip when it
detects street lamps (on entering built-up areas) or even an oncoming cyclist,
then return to full beam when no light source is detectable.

Both safety innovations have been introduced following widespread research
showing the inherent dangers posed by poorly lit roads or busy highways. German
road safety research has shown that approximately 50 per cent of serious
accidents are caused as a result of the driver not having enough information
about the road ahead to take avoiding action. The same research has also shown
that, while 75 per cent of all driving is done during daylight hours, more than
50 per cent of all fatal accidents happen during the hours of darkness. Similar
accident figures have been found in US studies.

When looking at developing BMW's Night Vision system, engineers considered two
types of imaging cameras on the market - Near Infrared (NIR) and Far Infrared
(FIR). NIR uses a source of infrared light and an infrared camera mounted on
the front of the car. Any infrared light reflected from objects is collected
by the camera and then processed into an on-screen image. FIR on the other hand
uses a thermal imaging camera to directly register heat radiated from objects
with an image then being displayed on-screen.

After a process of evaluation FIR was considered superior. Since there was no
need for another light source to be projected from the car fewer components are
used. FIR also had a greater area of coverage and, unlike NIR, couldn't be
confused by the lights of oncoming vehicles, traffic lights or road signs with
their strong reflective qualities.

Night Vision can be activated by a button alongside the headlight switch. An
option in the iDrive menu allows the driver to select brightness and contrast
while choosing between a full screen or split screen display.

High-Beam Assistant:

High-Beam Assistant was developed after research showed that high beam
headlights could, and arguably should, be used in approximately 75 per cent
more occasions than they currently are. Further studies highlighted that
drivers who do switch to high beam often fail to deactivate it in time and,
consequently, dazzle other road users. The solution is High-Beam Assistant, a
system that uses a light-seeking camera located in the rear view mirror housing
to monitor the road for up to 1,000 metres ahead.

To activate High-Beam Assistant the driver need only turn the headlight switch
to the automatic position and leave the high beam/low beam headlight stalk
pushed forward to high. A check control light in the instrument binnacle tells
the driver High-Beam Assistant is operational.

Pricing for the High-Beam Assistant on the BMW 5, 6 and 7 Series have been
confirmed at £95.00 but the cost for Night Vision, which is due to be launched
in late 2005, is yet to be confirmed.

Note: Xenon main beam headlights first appeared on BMW cars in 1991, and for
both low and high beam in 2001 (Bi-Xenon). This was followed by Adaptive
Headlights, which swivel to illuminate the road when cornering, in 2003.
High-Beam Assistant represents the next stage in lighting safety.

CO2 emission information.

The values for fuel consumption, CO2 emissions and energy consumption shown were determined in a standardised test cycle according to the European Regulation (EC) 715/2007 in the version currently applicable. The figures refer to a vehicle with basic configuration in Germany and the range shown considers transmission (automatic or manual) and the different wheels and tyres available on the selected model and may vary during the configuration.

The values of the vehicles labelled with (*), are already based on the test cycle according to the new WLTP regulation and are translated back into NEDC-equivalent values in order to allow a comparison between vehicles. More information on the transition from NEDC to WLTP test procedures can be found here.

These figures are intended for comparison purposes and may not be representative of what a user achieves under usual driving conditions. For plug-in hybrid vehicles and battery electric vehicles the figures have been obtained using a combination of battery power and petrol fuel after the battery had been fully charged. Plug-in hybrid vehicles and battery electric vehicles require mains electricity for charging. The CO2 emissions labels are determined according to Directive 1999/94/EC and the Passenger Car (Fuel consumption and CO2 Emissions Information) Regulations 2001, as amended. They are based on the fuel consumption, CO2 values and energy consumptions according to the NEDC cycle.

A guide on fuel economy and CO2 emissions which contains data for all new passenger car models is available at any point of sale free of charge. For further information you can also visit this link.
