RUNNING AND USE CONDITIONS AFFECTING FUEL CONSUMPTION
(examples and differences with respect to goods transportation vehicle data)
IMPORTANT
Although fuel consumption mea-
surements procedure aim at defining
realistic values, fuel consumption is in-
fluenced by factors such as:
Driving style and vehicle usehigh
speed, frequent acceleration, frequent
gear shifting, door-to-door deliveries,
etc.
Just for passenger transportation
versions with 2.3 and 2.8 JTD engines,
reduced consumption can be obtained
by starting (on level road) in 2nd gear
instead of 1st gear.
Traffic and road conditions
queues, bending roads, steep roads,
bad road surface, etc.Weather conditions and tem-
peratures
low temperatures, thinner air, wind,
rain etc…;
Vehicle conditions
Poor maintenance (tyre pressure, fil-
ters, spark plugs, etc.), damaged body-
work
Load conditions
Heavy weights, not optimal load dis-
tribution, large weights on roof rack,
etc.
Use of electric devices
Climate control, heater and electric
devices in general
Special conditions of use
Special vehicle conditions of use: roof
rack, trailer, open side windows, type
of tyres, etc.Special trim and adaptations
caravan, motor home, mega box, can-
vas cover, etc.
Some of these conditions are illus-
trated in these figures on the next
pages.
For more information, refer to the
advice in the chapter “Cheap running
that respects the environment.
The fuel consumption values shown
in the table in following pages were de-
fined according to the type-approval
specifications in European Directives.
Consumption values are defined by
means of the following procedures:
– an urban cycle: consisting of a
cold start and a simulated drive in city
streets;
– an extra-urban cycle: consisting
in frequent accelerations, in all gears,
