Switching off unnecessary consumers saves fuel.
What is unnecessary, however, remains a matter of opinion.
How much does it add to my car's fuel consumption * if I drive without air conditioning?
The answer to this is provided by
Johannes Kautenburger
,
test engineer at the KÜS expert organization
: Depending on the device and the performance it requires, a car uses around 10-15 percent fuel per 100 kilometers with the air conditioning switched on.
With frequent “Stop & Go” this can
mean
up to 2 liters more fuel
.
Long-term use of the air conditioning system may therefore be questioned.
Turn off all unnecessary electrical loads,
is fundamentally the right approach
,
in order to save fuel
.
Better to open windows than switched on air conditioning?
But with a sense of proportion, of course: It is not beneficial for concentration behind the wheel to do without the air conditioning at high temperatures.
Also,
open side windows or an open sunroof are not necessarily cheaper
: They impair the flow of air, which
costs more fuel,
especially
at higher speeds
.
Air conditioning in the car: why it should also be used in winter
Not using the air conditioning at all in winter can also have a
negative impact on its lifespan
.
Because only with regular operation, the seals and the compressor remain well lubricated.
Regular use also prevents
mold or bacteria from
spreading indoors.

Switch off air conditioning early
In order to prevent fungal growth, drivers should also
switch off the cooling function shortly before the end of the journey
and only leave the fan running so that the moisture is blown out of the system.
The air conditioning system also dehumidifies the air and helps against fogged windows.
By the way, the driving style has the greatest influence on fuel consumption.
To
up to a quarter, the fuel consumption is reduced
when driving with foresight.
If a red light is in sight, let the car
coast slowly
and
disengage as late as possible in
order to use the engine's overrun cut-off.
If you take your foot off the gas, the injection units block the fuel supply, while the engine brakes the car
without burning fuel
