If the interpolation method (see paragraph 3.2.3.2. of Sub-Annex 7) is not used, the road load delta method for vehicle N shall be calculated in accordance with the following equations:
f0,N = f0,R + f0,Delta
f1,N = f1,R + f1,Delta
f2,N = f2,R + f2,Delta
where:
Nrefers to the road load coefficients of vehicle N;
Rrefers to the road load coefficients of reference vehicle R;
Deltarefers to the delta road load coefficients determined in paragraph 6.8.1.
