General notes on the technical data

How are the figures measured?
Fuel consumption
Fuel consumption and emission values are determined according to Euro-
pean Commission Directive 99/100/EC. They take the actual kerb weight
(weight class) into consideration. To calculate the consumption rate, two
measuring cycles are carried out on a rolling road test bed. The test criteria
are as follows:
Urban cycle
The urban cycle starts with an engine cold start. City driving is then simulated.
In the extra urban cycle the vehicle undergoes frequent acceleration and braking in all gears, as in normal everyday driving. The
road speed ranges from 0 to 120 km/h.
Extra urban cycle
The average overall consumption is calculated with a weighting of around 37% for the urban cycle and 63% for the extra urban
cycle.
Combined
The exhaust gases are collected during both driving cycles to calculate carbon dioxide emissions. The gas composition is then
CO emissions

analysed to evaluate the CO content and other emissions.

Note
•
The fuel consumption and emission values quoted in the tables below are
based on an empty basic vehicle without optional extras. The kerb weight of
the vehicle may vary depending on the equipment fitted and thus the weight
category with a relative increase of consumption and emission of CO Your

Authorised Service Centre will be able to inform you of the figures which apply
to your vehicle.

Actual consumption may vary from quoted test values, depending on
personal driving style, road and traffic conditions, the weather and the condi-
tion of the vehicle.
