On a 25-30 miles journey (through villages, countryside, etc) starting with 100% charge, which usage would result better mpg? Just leave it hybrid mode and let the car figure out how to go (I believe it would use up the HV battery quite quickly) or better keep switching manually between E-Save and Hybrid depending the speed and traffic nature?
At this time of year I use E-Save to start off and get some heat into the cabin. I would also use E-Save if there is a steep hill to go up. Otherwise leave it in Hybrid. To be honest I think the difference will be marginal, but the heater does take a lot of battery power at this time of year.
