Type of traction REESS (model, capacity, nominal voltage, nominal power, type of coolant (air, liquid));

                  (d) Transmission type (e.g. manual, automatic, CVT) and transmission model (e.g. torque rating, number of gears, numbers of clutches, etc.);

                  (e) Number of powered axles;

                  (f) Type of electric energy converter between the electric machine and traction REESS, between the traction REESS and low voltage power supply and between the recharge-plug-in and traction REESS, and any other characteristics having a non-negligible influence on fuel consumption (or fuel efficiency) and electric energy consumption under WLTP conditions. At the request of the manufacturer and with the approval of the approval authority, electric energy converters between recharge-plug-in and traction REESS with lower recharge losses may be included in the family;

                  (g) Operation strategy of all components influencing the fuel consumption (or fuel efficiency) and electric energy consumption within the powertrain;

                  (h) n/v ratios. This requirement shall be considered fulfilled if, for all transmission ratios concerned, the difference with respect to the n/v ratios of the most commonly installed transmission type and model is within 8 per cent.

              6.3.3. Road load family

              Only vehicles that are identical with respect to the following characteristics may be part of the same road load family:

                  (a)  Transmission type (e.g. manual, automatic, CVT) and transmission model (e.g. torque rating, number of gears, number of clutches, etc.). At the request of the manufacturer and with approval of the responsible authority, a transmission with lower power losses may be included in the family;

                  (b) Number of powered axles.

              If at least one electric machine is coupled in the gearbox position neutral and the vehicle is not equipped with a coastdown mode (paragraph 4.2.1.8.5. of Annex B4) such that the electric machine has no influence on the road load, the criteria in paragraph 6.3.2.2. (a) and paragraph 6.3.2.3. (a) shall apply.

              If there is a difference, apart from vehicle mass, rolling resistance and aerodynamics, that has a non-negligible influence on road load, that vehicle shall not be considered to be part of the family unless approved by the responsible authority.

              6.3.4. Road load matrix family

              The road load matrix family may be applied for vehicles with a technically permissible maximum laden mass ≥ 3,000 kg.

              Vehicles with a technically permissible maximum laden mass ≥ 2,500 kg may be part of the road load matrix family provided the driver seat R-point height is above 850 mm from the ground.

              "R-point" means "R" point or "seating reference point" as defined in paragraph 2.4. of Annex 1 to the Consolidated Resolution on the Construction of Vehicles (R.E.3.).

              Only vehicles which are identical with respect to the following characteristics may be part of the same road load matrix family:

              (a)
