BMW X M in the environmental wind tunnel: snow storms at the press of a button.

Heat, cold, sun, rain, snow – in the Energy and Environmental

Test Centre of the BMW Group, a vehicle can drive through all

the world’s climate zones in just one day.

AROUND THE WORLD IN EIGHT HOURS.

Secured: during the evaluation, the vehicle

is anchored to the test bed (left). Solarium:

high-power radiant lamps in the ceiling

simulate strong sunshine.

A BMW X M in a snowstorm. Minute snow-

powder crystals rush past at well over km/h,

they sweep over the windscreen and whistle

through the wheel arches. The vehicle’s wheels

turn at terriﬁ c speed. And yet the BMW X M

doesn’t move a single metre forward.

In the Energy and Environmental Test Centre

(EVZ) of the BMW Group, which opened in

spring , reality is turned upside down. It is

not the car that moves, but the environment.

The BMW X M is locked down to the test

bed, its wheels driven by the rollers on which

it stands. And whether it’s the climatic, thermal

or environmental wind tunnel, or it’s the altitude

or cold-testing chamber, in the EVZ, the road is

right there in the laboratory. Likewise, whatever

weather may be required. Heat, cold, sun, rain

and snow are all available at the press of a

button. Enormous fans, meanwhile, can create

a ferocious airstream of up to km/h.

The pay-off. Many tests that involved engineers,

mechanics, prototypes and equipment travelling

to the world’s hot and cold regions and areas

of dry desert and tropical humidity, can now be

done at the Research and Innovation Centre (FIZ)

of the BMW Group in Munich. Which also

happens to be right next to the six-storey,

, square metre EVZ. This saves time

and money and protects the environment by

eliminating many long-distance journeys.

For the snowstorm test, the crew would have

previously travelled to Scandinavia or Alaska.

Today it can be done at home. This is when

investigations are carried out to see if ﬁ ne

snow crystals can penetrate the engine’s air

intake system and block the air ﬁ lter, thus

leading to engine failure due to lack of air. Now

it’s possible to create a blizzard even at the

height of summer and reproduce it frequently

and under precisely the same conditions.

More than  test drives are stored with every

detail in the EVZ. From stop-go trafﬁ c in the

city and top speeds on the autobahn, through

to journeys at a height of , metres in the

altitude chamber. And in all weathers and

temperatures from minus  to plus  degrees

centigrade. But it’s not just the air intake system

and engine of the BMW X M that need to be

capable of coping with extremes. The same is

true of everything from the engine control unit

and the brakes to the air conditioning unit.

Weeks, months and thousands of miles are no

longer always required. Thanks to the ﬁ ve test

beds in the unique Energy and Environmental

Test Centre, a vehicle can drive through all the

climatic zones of the world in just eight hours.
