324 Technical Data
Weights, payload and roof load
The payload is the difference between the
permitted gross vehicle weight (see
identification plate, page 312) and the EC
kerb weight.
To calculate the kerb weight, enter the
data for your vehicle below:
z Kerb weight from
Table 1,
page 325
z Additional weight of
equipment versions from
Table 2, page 330
z Weight of heavy
accessories from Table 3,
page 332
The total
is the EC kerb weight.
Optional equipment and accessories
increase the kerb weight, which means that
the payload will also change slightly.
Note the weights given in the vehicle
documents.
The combined total of front and rear axle
loads must not exceed the permissible
gross vehicle weight. For example, if the
front axle is bearing its maximum
permissible load, the rear axle can only
bear a load that is equal to the gross
vehicle weight minus the front axle load.
With a connected trailer and full load on
the towing vehicle including all passengers,
in the hatch the maximum permitted rear
+ .............. kg
axle load (see rating plate or vehicle
documents) may be exceeded by 65 kg (5-
door) or 70 kg (3-door), and the maximum
+ .............. kg
gross vehicle weight by 45 kg. In the Estate,
the maximum permitted rear axle load
may be exceeded by 60 kg and the
maximum gross vehicle weight by 30 kg. If
+ .............. kg
the maximum permitted rear axle load is
= .............. kg
exceeded, a top speed of 100 km/h applies.
If lower top speeds are stipulated
nationally when towing a trailer these must
be observed.
See the identification plate or vehicle
documents for permissible axle loads.
Roof load
The permissible roof load is 75 kg and
100 kg for caravan with roof railing. The
roof load is the combined weight of the
roof rack and the load.
Roof loads are not permitted on the Astra
TwinTop.
