There are several reasons for increased fuel
consumption compared with the table's val-
ues. Examples of this are:
•
The driver's driving style.
•
If the customer has specified wheels
larger than those fitted as standard on the
model's basic version, then resistance
increases.
•
High speed results in increased wind
resistance.
•
Fuel quality, road and traffic conditions,
weather and the condition of the car.

Even a combination of the above-mentioned
examples can result in significantly improved
consumption. For further information, please
refer to the regulations referred to
Large deviations in fuel consumption may
arise in a comparison with the EU driving

cycles which are used in the certification of
the car and on which the consumption figures
in the table are based.
Consumption is higher and power output
lower for fuel with an octane rating of
91 RON.
2 Official fuel consumption figures are based on two standardised driving cycles in a laboratory environment ("EU driving cycles") all in accordance with EU Regulation no 692/2008 and 715/2007
(Euro 5 / Euro 6) and UN ECE Regulation no 101. The regulations cover the driving cycles for city driving and driving on main roads. - City driving - the measurement starts with cold starting the
engine. The driving is simulated. - Driving on main roads - the car is accelerated and braked at speeds between 0-120 km/h. The driving is simulated. - Cars with manual transmission are started
in 2nd gear. The value for combined driving, which is reported in the table, is a combination of city driving and driving on main roads, in accordance with legal requirements. CO
exhaust gases are collected in order to calculate the carbon dioxide emissions during the two driving cycles. These are then analysed and give the value for CO

NOTE
Extreme weather conditions, driving with a
trailer or driving at high altitudes in combi-
nation with fuel grade are factors that
could affect the car's performance.
