Fuel consumption and CO

2

emissions

The information in the tables below is in
accordance with WLTP (Worldwide Harmon-
ised Light-Duty Vehicles Test Procedure),
which is an international test method for
vehicles equivalent to a passenger car
designed for laboratory testing.

The fuel consumption for a vehicle is meas-
ured in litres per 100 km and carbon dioxide
emissions (CO

2

) are measured in gram CO

2

per km.

Explanation

Weighted combined value. The
value is weighted between elec-
tric mode and fuel mode over the
entire drive cycle.

gram CO

2

/km

litres/100 km

Certified value for the car's
potential range ("up to") in km in
electric mode. The value should
not be interpreted as an expected
range, and the range is difficult to
achieve during normal driving.

Urban and suburban driving

Average value over all four drive
cycle phases (urban, suburban,
extra-urban and motorway driv-
ing)

Automatic gearbox

Low value

High value

NOTE

If there is no consumption and emissions
data in the table, this is available in an
enclosed supplement.

NOTE

The capacity of the hybrid battery dimin-
ishes with age and use, which may result
in increased use of the internal combustion
engine and, as a consequence, reduced
fuel economy and reduced range during
electric operation.

Drive mode PURE

The values in the table above for fuel con-
sumption, CO

2

emissions, and range for elec-

tric mode are based on special drive cycles
(see below). The car's weight may increase
depending on its equipment level. Together
with how heavily the car is loaded, this affects
fuel consumption and CO

2

emissions, and

reduces its range in electric mode. According
to WLTP, each car has unique fuel consump-
tion, CO

2

emission values and electric range

values, depending on how the car is equipped.
These values range between the low value and
high value in the table above. In many mar-
kets, you can find your car's unique fuel con-
sumption, CO

2

emission values and electric

range values in the car's registration docu-
ment.

The certified values for the car should not be
interpreted as the expected values. The certifi-
cation values are the comparative values

obtained during special drive cycles (see
below).

There are several reasons for fuel consumption
that is higher and an electric range that is
shorter than the values in the table. Examples
of these include:

•

If the car is not regularly charged from the
mains.

•

If the car is equipped with extra equip-
ment that affects its weight.

•

Driving style.

•

If the customer chooses wheels other than
those mounted as standard on the basic
version of the model, this could increase
rolling resistance.

•

High speed causes increased air resis-
tance.

•

Fuel quality, road and traffic conditions,
weather and the condition of the car.

A combination of the examples above could
increase consumption considerably.

There may be huge deviations in fuel con-
sumption if comparing to the drive cycle pro-
files (see below), which are used in the certifi-
cation of the car and on which consumption
figures in the table are based. For further infor-
mation, please refer to the referenced regula-
tions.

NOTE

Extreme weather conditions, driving with a
trailer or driving at high altitudes, in combi-
nation with poorer fuel quality than recom-
mended, are factors that considerably
increase the car's fuel consumption.

WLTP standard

From and including 1 September 2018, a new
standard was introduced for calculating con-

||

SPECIFICATIONS

706

sumption values in the car. The WLTP stand-
ard (Worldwide Harmonised Light-Duty Vehi-
cles Test Procedure) represents the average
driving conditions for everyday driving. In
comparison with the previous standard
(NEDC), WLTP takes into account more varied
traffic situations and speeds, but also equip-
ment and weight classes. Optional equipment
that affects consumption is deactivated during
testing, e.g. air conditioning, seat heating, etc.
The new standard should provide more realis-
tic figures when it comes to fuel consumption,
carbon dioxide and emissions, as well as
range for electric mode. The values are
intended to allow comparison between differ-
ent cars and not to represent your typical nor-
mal consumption and range for electric mode.

Drive cycle profiles

A drive cycle simulates actual average driving
of the car. The standard is based on four differ-
ent drive cycle profiles. The four drive cycle
profiles are:

•

Urban driving

– slow driving

•

Suburban driving

– average driving

•

Extra-urban driving

– fast driving

•

Motorway driving

– very fast driving.

Every drive cycle is determined by different
conditions such as speed, time and mileage,
for example.

The official value for combined driving, which
is shown in the table, is a combination of the
results from the four drive cycles, in accord-
ance with legal requirements.

The exhaust gases are collected in order to
extrapolate the carbon dioxide emissions (CO

2

emissions) during the four drive cycles. These
were then analysed to determine the value for
CO

2

emissions.
