Morning Glos-Guy
I visted family over the weekend, as I do each month. I charged the battery at my mums and filled up ready for my return journey yesterday, as fuel is often 3-4pl cheaper up there.
As mentioned before even with a full charge, I drive back in HEV mode and let the car go into EV mode if it wants and then when, I’m closer to home, I use up any remaining battery, if there is any.
Around half way of the 185 mile journey back, I pulled over to get a can out of the coolbox and thought I’d take a quick pic, the battery was hovering around 3/4 full, which, I thought I’d got in the pic. 17 miles from home, I switched to EV, so t use up the remaing juice. I have charged for a while this morning, so the 2nd pic, is remaing fuel range -21 miles. My overall journey registered 47.5mpg, when pulling on the drive, which I find is a better outcome, than if you used the full battery in full, at start of journey.
I find it rather odd, doing a journey in HEV, rather than using the battery at the start yeilds better results, but I have cross referenced it the last 3-4 times by filling up the next day and doing the calculations.
