FUEL CONSUMPTION
The fuel consumption figures, in the tables below, have
been determined according to the homologation tests laid
down by specific European Directives.
The procedures below are followed for measuring con-
sumption and emissions:
❒ urban cycle: cold start and driving style that replicates
the speed and gear changes as per the European di-
rective. There are a series of accelerations, decelera-
tions, constant speeds and stops with engine idling. The
top speed reached during the cycle is 50 km/h and the
average speed is 19 km/h.
❒ extra-urban cycle: done after the urban cycle as per
the European directive. The top speed reached dur-
ing the cycle is 120 km/h and the average speed is
63 km/h.
❒ combined cycle: determined by an average of the ur-
ban cycle (37 per cent weighting) and extra-urban cy-
cle (63 per cent weighting) consumptions.
IMPORTANT
In practice, fuel consumption may be higher than the val-
ues obtained during the approved tests. Here are some of
the major factors that can lead to a difference between
test and real consumption.
1) Vehicle condition: inadequate servicing, use of roof
racks, trailers, heavy loading, high usage of electrical de-
vices and the air conditioning.
2) Driving style: frequent cold starts for short journeys,
poor engine warming technique, gear selection, high
speeds, sudden acceleration and braking.
3) Traffic and road conditions: driving in traffic, steep hills
or winding roads, road surface conditions.
4) Atmospheric conditions: intemperate weather, wind,
rain, snow, high altitude.
5) Proportion of use in towns and cities, in the country
and on motorways.
