11 Specifications
There are several reasons for increased fuel
consumption compared with the table's val-
ues. Examples of this are:
CO2 emissions and fuel consumption
(vehicle gas - CNG) - for Bi-Fuel
NOTE
There are many different qualities of
gas, as well as gases with lower
energy content and range.

•
The driver's driving style.

The fuel consumption specified above
applies for combined driving. During
urban driving or fast motorway driving
the consumption is higher and during
calm extra-urban driving it is lower.

A combination of the above-mentioned

CNG specifications
Type designation Bi-Fuel
Large deviations in fuel consumption may
arise in a comparison with the EU driving
cycles2 which are used in the certification of
the car and on which the consumption figures
in the table are based.
Output, CNG
Power output is the
same as for petrol.
Emission level
Euro 6
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.

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 urban driving and extra-urban driving. - Urban driving - the measurement starts with cold starting the
engine. The driving is simulated. - Extra-urban driving - the car is accelerated and braked at speeds between 0-120 km/h (0-75 mph). The driving is simulated. - Cars with manual gearbox are
started in 2nd gear (applies to cars with up to 18-inch wheels). The value for combined driving, which is reported in the table, is a combination of urban driving and extra-urban driving, in accord-
ance with legal requirements. CO2 emissions - the 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 CO2 emissions.
