Formula 1(b)

Or, if (TMn,H · RRn,H – TMn,L · RRn,L ) = 0, or, where applicable, (RMn,H · RRn,H – RMn,L · RRn,L ) = 0, Formula 2 shall apply:

The NEDC road load coefficients shall, in the cases (a) to (d), be calculated using the formulae set out in point 2.3.8.1.1, where references to vehicle H shall be considered as references to the individual vehicle.

In the case (a), CO2 extrapolation may only be performed, if the difference between NEDC vehicle H and L is equal to or higher than 5 g CO2/km. The interpolation line may in that case be extrapolated by a maximum of 3 g CO2/km above the CO2 emissions of vehicle H, or below those of vehicle L. If the extrapolation exceeds 3 g CO2/km, or the difference between NEDC vehicle H and L is lower than 5 g CO2/km, the manufacturer shall determine a new interpolation line for that family in accordance with points 2 and 3 of this Annex.’;
