RDE PHEV. SUMMARY
RDE PHEV, EG-603, 04.05.2016
• By adapting EMroad according to BMW proposal, „invalid“ drives according to original
EMroad turn into valid, especially for CD-Mode.
• Starting in CS-Mode cannot avoid switching to CD-Mode (e.g. by SAVE Battery Mode or
downhill drive). Thus widening the tolerance margin is not sufficient as significant share of
distance could be driven in electric mode only => no CO2 windows.
Furthermore severe driving could be declared as valid by increasing the margin.
