Open issue 6 “Use of the gearbox, required data” concerns the following:

• modification of the definition of n_{min_drive} to make it more appropriate for modern engines and to make manipulations more difficult.
• Addition of n_max to section 2 and amendment of required data because the current definition is not appropriate for low powered vehicles.
• Replacement of P_normwot(n_{norm i, j}) in Section 2 (i) by P_wot(n _{i, j}) because there is no need for the normalisation.
