I would concur with others on your driving style and getting maximum range.
Keep the display on the dash that shows your instant range per KWh and you will see where you can improve. Treat the accelerator pedal as if you have an egg between it and your foot. Once you get up to speed then back off ever so slightly again and you will see you can keep the speed up and still drop the battery usage. On longer trips save electric driving only when you can be less than 75mph and ideally 30-50 mph. Anything over 80mph and you should only be in hybrid mode and at that you can see that at times you only get 10mpg while mashing the accelerator but 24mpg otherwise.
