Original text. Later amendments are not shown.

C CO 2 = B MC − E MC × UF MC

The term UFMC of the Formula 2 will be hereafter simply written as ‘UF’ since it is the unique usage factor thanks to the previous simplification.

To determine BMC, the same modified testing conditions should be followed by a vehicle which does not have the coasting function.

The assumption is that the baseline vehicle is able to perform a sailing curve (line 2′ in Figure 2) without disconnecting the engine from the wheels, although with lower efficiency than a coasting vehicle (able to disconnect the engine from the wheels). Sailing is intended as the hypothetical coasting behaviour of the baseline vehicle.
