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 operation. 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.
