The fuel consumption values required by Regulation (EU) 1153/2017 (WLTP and, if applicable, NEDC) are provided by the manufacturer of the base vehicles (e.g. Fiat). Until around mid-2019, body manufacturers were not legally obliged to state CO2 values.
Currently, the procedure is as follows:
- The base vehicle manufacturer determines consumption values that are shown in the certificate of conformity (COC). At the same time, it is currently the case that Fiat, for example, does NOT supply NEDC values for N2 base vehicles (the majority of motorhomes are based on them as stage 1)! One of the reasons given for this is that motorhomes, as special purpose vehicles, are exempt from CO2 monitoring and therefore do not require NEDC values.
- The motorhome manufacturer determines the specific consumption values for its vehicles using a calculation tool provided by the base vehicle manufacturer and enters these in its certificate of conformity. In some cases, the calculation tools do not provide NEDC values!
The motorhome manufacturer can only adopt the values that the base vehicle manufacturer provides or that are determined by the calculation tool! The German Federal Motor Transport Authority (KBA) provides the so-called "Swedish formula" on its website.
The missing NEDC values can thus be determined and registered by the registration office! The registration may not be denied!
