•
If the car is equipped with extra equipment
that affects its weight.
•
Driving style.
•
If the customer chooses wheels other than
those mounted as standard on the basic ver-
sion of the model, this could increase rolling
resistance.
•
High speed causes increased air resistance.
•
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 consump-
tion if comparing to the EU driving cycles (see
below), which are used in the certification of the
car and on which consumption figures in the
table are based. For further information, please
refer to the referenced regulations.
NOTE
Extreme weather conditions, driving with a
trailer or driving at high altitudes, in combina-
tion with poorer fuel quality than recom-
mended, are factors that considerably
increase the car's fuel consumption.
EU driving cycles
The official fuel consumption figures are based
on two standardised driving cycles in a laboratory
environment ("EU driving cycles"), all in accord-
ance with EU Regulation no 692/2008 and
715/2007 (Euro 5 / Euro 6), 2017/1151 and
2017/1153. Since the driving cycles are also
used for quality control, there are stringent
requirements for test repeatability. Testing is
therefore conducted in a controlled manner and
only with the car's basic functions (e.g. air condi-
tioning, radio, etc. switched off). The results of the
official figures are therefore not naturally repre-
sentative of what the customer sees in actual
use.
The regulations cover the driving cycles "Urban
driving" and "Motorway driving":
•
Urban driving – the measurement starts
with a cold start of the engine. The driving is
simulated.
•
Motorway driving – the car is accelerated
and braked at speed of 0-120 km/h
(0-75 mph). The driving is simulated.
The official value for mixed driving, which is
shown in the table, is a combination of the results
from the "Urban driving" and "Motorway driving"
driving cycles in accordance with legal require-
ments.
To determine the carbon dioxide emissions (CO
2
emissions) during the two driving cycles, the
exhaust gases were collected. These were then
analysed to determine the value for CO
2
emis-
sions.
