Roof rack/ski rack
Remove the roof rack or the ski rack
from the roof after use. These
accessories decrease aerodynamic
penetration of the vehicle and have a
negative effect on fuel consumption.
When transporting particularly large
objects, use a trailer if possible.
Electric devices
Use electrical devices only for the
amount of time needed. The heated
rear window, additional headlights,
windscreen/rear window wipers and
heater fan need a considerable amount
of energy, therefore increasing fuel
consumption (by up to 25% in
the urban cycle).
Climate control system
Air conditioning leads to higher fuel
consumption (on average up to +20%).
If the temperature outside permits, try
and use the ventilation only.
Devices for
aerodynamic control
The use of non-certified spoilers may
adversely affect air drag and fuel
consumption.
DRIVING STYLE
The main driving styles that affect fuel
consumption are listed below.
Cranking
Do not warm up the engine at low or
high revs when the vehicle is stationary;
this causes the engine to warm up
more slowly, thereby increasing fuel
consumption and emissions. It is
therefore advisable to move off
immediately, slowly, avoiding high
speeds: in this way the engine will
warm up more quickly.
Unnecessary actions
Avoid accelerating when stopped at
traffic lights or before switching off the
engine. This action and also double
declutching is absolutely pointless on
modern cars and also increases
consumption and pollution.
Gear selection
As soon as the conditions of the traffic
and road permit, use a higher gear.
Using a low gear for faster acceleration
will increase consumption.
In the same way improper use of a high
gear increases consumption, emissions
and engine wear.
Max. speed
Fuel consumption increases
considerably with speed. Maintain a
constant speed, avoiding unnecessary
braking and acceleration, which cost
in terms of both fuel consumption and
emissions.
Acceleration
Accelerating violently will greatly affect
consumption and emissions:
acceleration should be gradual.
USAGE CONDITIONS
The main usage conditions that
negatively affect fuel consumption are
listed below.
Cold starting
Short journeys and frequent cold starts
do not allow the engine to reach
optimum operating temperature.
This results in a significant increase in
consumption levels (from +15 to +30%
on the urban cycle) and emissions.
