Correct economical and ecological
driving
Fig. 133 Fuel consumption in litres per
100 km (mpg) at different outside tempera-
tures
Fuel consumption, environmental impact and
engine, brake and tyre wear depend largely
on three factors:
●
Personal driving style.
●
Conditions of use (weather, road surface).
●
Technical requirements.
Savings of up to 25% in fuel consumption
are possible with an appropriate driving style
and the adoption of certain simple tips.
Changing gear early
General instructions: The highest gear is al-
ways the most economical. As a guideline,
for the majority of vehicles: at a speed of
30 km/h (19 mph), drive in third gear, at
40 km/h (25 mph) in fourth gear and at
50 km/h (31 mph) in fifth gear.
In addition, “skipping” gears when shifting
up helps to save fuel, weather and traffic
conditions permitting.
Do not wait until the last moment before
changing gear. Only use first gear when you
move off and change to second gear quickly.
Avoid the kick-down function in vehicles with
automatic gearbox.
Vehicles with a gear display help to achieve
an economical driving style as the display in-
dicates the best moment to change gear.
Let the vehicle roll
If you take your foot off the accelerator, the
fuel supply is stopped and consumption is
reduced.
Allow the vehicle to roll without accelerating,
for example when approaching a red traffic
light. However, if the vehicle is rolling too
slowly or the distance is too long, the clutch
pedal should be pressed to declutch. The en-
gine will then operate at idle speed.
If the vehicle is going to be at a standstill for
a period of time, switch off the engine; for ex-
ample, while waiting at a level crossing. In
vehicles which have the Start-Stop function
on, the engine switches off automatically
when the vehicle is not moving.
