A method to determine operational efficiency of a heavy duty vehicle, including quantifying an engine efficiency parameter to form an engine efficiency parameter quantified score, quantifying a drive train parameter to form a drive train 5 parameter quantified score, quantifying an aerodynamic parameter to form an aerodynamic parameter quantified score, quantifying a tyre rolling resistance parameter to form a tyre rolling resistance parameter quantified score, quantifying an inertia parameter to form an inertia parameter quantified score, quantifying a pollution parameter to form a pollution parameter quantified score and quantifying a o safety parameter to form a safety parameter quantified score, wherein each of said parameter quantified scores are weighted in light of their predetermined level of importance and combined to form an operational efficiency score for the heavy duty vehicle. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ..J. . . . . . . . . . . . . . . . . . . . . .. . . . .. .. .. .. . a.. .. .. .. .. .. 3;o 0. . .. . . ...
