Weights ABC

The technically permissible maximum laden mass of the vehicle (e.g. 3,500 kg) is a mass specification set by the manufacturer which the vehicle must not exceed. Information on the technically permissible maximum laden mass of the model you have chosen can be found in the technical data. If the vehicle exceeds the technically permissible maximum laden mass in everyday driving, this constitutes an administrative offence which may result in a fine.

The specified mass in running order is a default value defined in the type-approval procedure. Due to manufacturing tolerances, the actual weighed mass in running order may deviate from the value stated above. Deviations of up to ± 5 % of the mass in running order are legally permissible and possible.
In simple terms, the mass in running order is the basic vehicle with standard equipment plus a legally fixed standard weight of 75 kg for the driver. This essentially includes the following items: 

•  the unladen weight of the vehicle together with the bodywork, including operating fluids such as greases, oils and coolants; 
•  the standard equipment, i.e. all equipment items that are included as standard in the factory-fitted scope of delivery;
•  the fresh water tank filled to 100 % in driving mode (driving fill according to manufacturer's specifications; 20 litres) and an aluminium gas cylinder filled to 100 % with a weight of 16 kg;
•  the fuel tank, which is 90 % full, including fuel;
•  the driver, whose weight – regardless of the actual weight – is generally specified as 75 kg in accordance with EU law. 

The manufacturer-specified mass for optional equipment is a value set by Bürstner per layout for the maximum mass of optional equipment that can be ordered. This limit is intended to ensure that the minimum pay-mass, i.e. the legally prescribed free mass for baggage and retrofitted accessories, is actually available for the vehicle load capacity of the vehicles delivered by Bürstner.

The mass of the passengers is set a standard value of 75 kg for each seat provided by the manufacturer, regardless of the actual weight of the passengers. The mass of the driver is already included in the mass in running order (see no. 2 above) and is therefore not included again. In the case of a motorhome with four permitted seats, the mass of the passengers is therefore 3 * 75 kg = 225 kg. 

The EU regulations stipulate a fixed minimum pay-mass for motorhomes, which must remain as a minimum for baggage or other non-factory-fitted accessories. This minimum pay-mass is calculated as follows: 10 * (n + L)
Where: “n” is the maximum number of passengers plus the driver and “L” is the overall length of the vehicle in metres.
For a motorhome with a length of 6 m and 4 approved seats, the minimum pay-mass is therefore e.g. 10 kg * (4 + 6) = 100 kg.

The additional weight of optional equipment and packages increases the actual mass of the vehicle (= mass in running order plus selected optional equipment) and reduces the pay-mass. The specified value shows the additional weight compared to the standard equipment of the respective layout. The total weight of the selected packages and optional equipment must not exceed the manufacturer-specified mass for optional equipment.

The Vario seat is an optional 5th seat considered as a regular seat when calculating the minimum payload and passenger mass. To obtain a 5th seat, it must be ensured that the minimum payload is maintained and all other legal mass values are observed. For detailed information, please contact our trading partners.

To inform you as best as possible and transparently about the weights in our sales documents (print and digital), we are generally guided by the legally prescribed terminology. Since July 6, 2022, these have been specified in particular in the Implementing Regulation (EU) 2021/535 (previously: Regulation (EU) No. 1230/2012). The Implementing Regulation (EU) 2021/535 is made available online in the various EU languages: https://eur-lex.europa.eu/legal-content/DE/ALL/?uri=CELEX:32021R0535
