I think it's general consensus that the range meter is just a random number generator.
Don't understand how you get 92km (57mile) from a car that is designed to only do 59km (37mile). Unless you're driving in petrol&electric hybrid mode.
Mine often tells me that I'll do random miles. 28, 35, 41, 45 and once 51. Although I think I have done late 30s, 50 has never been achieved. If it says anything like late 40s after I stop and restart it always drops back down to a more sensible value
.You didn't write down how much your car was showing you. The calculation is not reliable, it has its flaws. When charging at 99%, it will show a range of 65 km, and when 100% charged, it will suddenly show a range of 75 km. When driving after 2 km, the range drops to 66 km, for example. I charge to 80% most often, so I don't have this error. I charge from photovoltaics at home and when I need to, I also charge at work. Consumption with mileage is correct for me.
I drove 92 km, of course, in pure EV mode.
The problem of a short range can also be caused by an incorrect driving style. Many people like to recuperate.
And I don't understand at all if someone is using L mode. Don't recuperate unless you need to brake. By recuperation you lose about 20 to 30% of the energy That is, when converting kinetic energy into electrical energy and again into kinetic energy. Sail, used preferably N on the selector and does not produce energy loss by recuperation. Anticipate traffic and try not to recuperate or otherwise slow down. When the road situation requires that you need to slow down or stop, depress the brake pedal properly and start recuperation. This saves a lot of energy that would go to heat in the brakes if not recuperate.
Kuga PHEV has incorrectly set increased recuperation in eco mode. In eco mode, recuperation should be switched off when the accelerator pedal is released.
I'm sorry, my English is from a translator.
