ANNEX 10  
 
ANNEX  
to the  
COMMISSION REGULATION  
amending Commission Regulation (EU) 2017/1151 for the purpose of adopting to 
technical progress the emission type approval procedures for light passenger and 
commercial vehicles    
EN 1  EN ANNEX X 
In Annex XII, point 2  is replaced by the following:  
‘2. DETERMINATION OF CO2 EMISSIONS AND FUEL CONSUMPTION FROM 
VEHICLES SUBMITTED TO MULTI -STAGE TYPE -APPROVAL OR INDIVIDUAL 
VEHICLE APPROVAL  
2.1 For the purpose of determining the CO2 emissions and fuel consumption of a vehicle 
submitted to multi -stage type -approval, as defined in Article 3(8) of Regulation (EU) 
2018/858, the procedures o f Annex XXI apply. However, at the choice of the manufacturer 
and irrespective of the technically permissible maximum laden mass, the alternative described 
in paragraphs 2.2. to 2.6. may be used where the base vehicle is incomplete.  
2.2. A road load matrix  family, as defined in paragraph 6.3.4. of UN Regulation No 154, 
shall be established based on the parameters of a representative multi -stage vehicle in 
accordance with paragraph 4.2.1.4. of Annex B4 to UN Regulation No 154.  
2.3. The manufacturer of the ba se vehicle shall calculate the road load coefficients of 
vehicle HM and LM of a road load matrix family as set out in paragraph 5. of Annex B4 to 
UN Regulation No 154 and shall determine the CO2 emission and fuel consumption in a Type 
1 test of both vehicl es. The manufacturer of the base vehicle shall make available a 
calculation tool to establish, on the basis of the parameters of completed vehicles, the final 
fuel consumption and CO2 values as specified in Annex B7 to UN Regulation No 154.  
2.4. The calcul ation of road load and running resistance for an individual multi stage 
vehicle shall be performed in accordance with paragraph 5.1. of Annex B4 to UN Regulation 
No 154.  
2.5. The final fuel consumption and CO2 values shall be calculated by the final -stage 
manufacturer on the basis of the parameters of the completed vehicle as specified in 
paragraph 3.2.4. of Annex B7 to UN Regulation No 154 and using the tool supplied by the 
manufacturer of the base vehicle.  
2.6. The manufacturer of the completed vehicle shall include, in the certificate of 
conformity, the information of the completed vehicles and add the information of the base 
vehicles in accordance with Commission Implementing Regulation (EU) 2020/683.  
2.7. In the case of multi stage vehicles submitted to individual vehicle approval, the 
individual approval certificate shall include the following information:  
 (a) the CO2 emissions measured in accordance with the methodology set out in 
points 2.1 to 2.6.;  
 (b) the mass of the completed vehicle in running  order;  
 (c) the identification code corresponding to the type, variant and version of the 
base vehicle;  
 (d) the type -approval number of the base vehicle, including the extension number;  
 (e) the name and address of the manufacturer of the base vehicle;  
 (f) the mass of the base vehicle in running order.  
2.8. In the case of multi stage type approvals or individual vehicle approval where the base 
vehicle is a complete vehicle with a valid certificate of conformity, the final stage 
manufacturer shall consult  the base vehicle manufacturer to set the new CO2 value in 
accordance with the CO2 interpolation using the appropriate data from the completed vehicle 
or calculate the new CO2 value on the basis of the parameters of the completed vehicle as  
EN 2  EN specified in paragraph  3.2.4. of Annex B7 to UN Regulation No 154 and using the tool 
supplied by the manufacturer of the base vehicle as mentioned in point 2.3. If the tool is not 
available or the CO2 interpolation is not possible, the CO2 value of Vehicle High from the 
base vehicle shall be used with the agreement of the approval authority. ’.
