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.
