Munich. For a long time, motorists regarded air
conditioning merely as a guarantee of a cool workplace when behind the
wheel. During the early 1980s, the optional extra was predominantly
ordered as protection against the midsummer heat inside the car, true
to the motto: the heat has to stay out, irrespective of how hot the
sun is. The greater the “refrigerator feeling” experienced
by occupants was, the more effective an air conditioning system was
considered to be.
However, over the years, consumers have changed their attitude and
the demands on interior climate comfort have increased significantly.
Whether in extreme heat, heavy rainfall or severe cold, a cosy
interior climate has become a must.
In the case of the new BMW 3 Series, air conditioning experts go even
a step further, as particularly good air quality is also crucial for
best possible interior climate comfort. Besides automatic air
circulation control, which is activated for instance in increased
concentrations of fine particulate and exhaust gases in tunnels or
behind HGVs, the standard air conditioning unit featured in the new
BMW 3 Series employs an additional filter system that also becomes
effective when switched to the air circulation mode.
As a result, unpleasant environmental odours such as those sometimes
experienced in industrial areas or in the streets of large cities are
almost entirely eliminated. The perfect interaction between the
automatic air circulation control and the filter system noticeably
enhances air quality inside the BMW 3 Series. Even when the air
conditioning is not in use, the additional filter remains active.
When opting for a two-zone automatic climate control system, both the
driver and the front seat passenger are able to set the desired
temperature for their seat area individually and according to
preference. The temperature of the air leaving the air vents as well
as the amount and distribution of air are automatically regulated.
Depending on intensity and radiation angle of the sun, the automatic
climate control system adapts its degree of effectiveness (solar
compensation) and individually adjusts the interior temperature to the
desired level on both the driver and front seat passenger sides.
Additional air vents, likewise variably adjustable and located in the
rear compartment, ensure that backseat passengers are also able to
enjoy a pleasant interior climate. In order to avoid fogged-up
windows, particularly during the cold and damp season, the new BMW 3
Series is also equipped with an automatic sensor-controlled
anti-fogging function, which intervenes by means of targeted
ventilation as soon as visibility is restricted.
After a frosty night or when it is bitterly cold, the new climate
control system quickly generates a remarkably high heat output. Within
the defrosting area of the windscreen, the field of vision is evenly
defrosted only shortly after a cold start. The increased heating
performance is of particular benefit to customers in Scandinavia, as
temperatures there often drop below minus 20 degrees in the winter.
Even in temperatures as low at that, the two-zone automatic climate
control system featured in the BMW 3 Series ensures that the car is
cosy and warm within the foot and head areas after around ten minutes,
and that includes the rear compartment.
Each air vent of the automatic climate control system is controlled
by a compact and centrally located flap mechanism, rendering
additional stepper motors unnecessary. This all results in a saving of
weight and space beneath the dashboard. Thanks to the compact design
of the automatic climate control system, it is possible for the first
time to offer the new BMW 3 Series with Head-Up Display – a new
feature in the premium middle class. Furthermore, in this way, space
has been created in the centre console for two cupholders.
Within the framework of Efficient Dynamics measures, BMW engineers
paid special attention to improving the fuel consumption of the new
BMW 3 Series. When the driver switches to the ECO PRO mode, the new
automatic climate control system operates using an optimised
heating/climate strategy. Without any noticeable loss in comfort,
fuel-efficiently is enhanced through reduced air-drying and cooling in
the interior as well as through the intermittently deactivated
In BMW’s own environmental wind tunnel, engineers are working
intensively on additional fuel savings and further optimisation of
in-car climate comfort. In this facility, it is possible to simulate
every climate zone on the planet, highly efficiently and within the
shortest time. There, mainly cold starts and de-icing tests are
carried out under the most extreme conditions. The aim of BMW
developers is to further shorten the engine warm-up phase, as higher
temperatures reduce friction, which in turn facilitates lower fuel
consumption and emission levels - totally in keeping with the BMW
