WolfieBase Posted May 7 Share Posted May 7 Greetings everyone, I recently embarked on a road trip in my PHEV CX60. All A and B roads in Wales, UK. I was not in a hurry, so I utilised "Boost," which activated the battery power approximately twice throughout a 100-mile journey. The remainder involved adhering to the prevailing circumstances. I have always believed that with prudent accelerator usage, the battery remains inactive, merely awaiting significant acceleration. However, during the journey, the battery depleted from 80% to nearly 0%. Is this typical, or is there a potential "leak" present? As previously said, operated in "Sport" mode throughout that duration. At that time, my average fuel usage was 35 MPG, which I find acceptable.

pharmoun Posted May 7 Share Posted May 7 Affirmative. In sport mode, it is typical for the batteries to significantly assist the engine, particularly while navigating hilly terrain. The power distribution is observable on the vehicle's information displays. Quote Link to comment Share on other sites More sharing options...
WolfieBase Posted May 7 Author Share Posted May 7 Thank you for the response. Is your car exhibiting the same behaviour? For me, it is simply a lack of common logic that both electric and petrol power operate simultaneously in sport mode with minimal torque/power utilisation. It appears that when driving above 100 miles, your battery will be depleted, regardless of efforts to conserve it for later use. If you desire a synergistic power of two powertrains, it will not be available. What occurred to me recently was unpleasant. Summary of modes and their functionality based on my experience. "Normal" mode attempts to utilise electric power at all times, rendering it nearly equivalent to "EV" mode. Operates effectively for a brief duration, then exhibits nonsensical behaviour, such as deactivating the internal combustion engine for five seconds at 60 MPH when the accelerator is not engaged. The "Sport" mode consumes power continuously and depletes the battery within 100 miles, but the miles per gallon (MPG) improvement is negligible compared to when the battery is completely discharged—yet another questionable innovation. "EV" essentially operates as "Normal," even transitioning to "Normal" when the accelerator is fully depressed. "Offroad" - I have not utilised it, but it may well be more prudent to conserve battery when feasible, as regenerative braking is virtually unfeasible while slow off-road driving.

pharmoun Posted May 7 Share Posted May 7 The 'Towing' mode is also accessible when towing. This mode appears to enable the gearbox to respond differently (at higher RPM) while maximising the delivery of electric vehicle power. (and additionally features a 'boost' function) Quote Link to comment Share on other sites More sharing options...

WolfieBase Posted May 7 Author Share Posted May 7 Moreover, the fuel efficiency significantly deteriorates in scenarios when the battery is unnecessarily utilised; this is not a viable alternative. Quote Link to comment Share on other sites More sharing options...
Ken_Lion Posted May 7 Share Posted May 7 No, it does not; you can establish a charge limit, often 20 percent is effective for me. Quote Link to comment Share on other sites More sharing options...
SD1too Posted May 7 Share Posted May 7 I consistently operate my vehicle in sport mode, although the battery remains at approximately 30-35% capacity. Even during extended journeys. Quote Link to comment Share on other sites More sharing options...
