I see a lot of people getting very concerned or confused about the estimated range displayed after a 100% charge.
My previous ICE car's petrol consumption went from 9.6l/100km to 17l/100km, depending on usage. It's estimated range to empty also changed based on usage.
I do not see people stressing over these fuel usage changes which happen in ICE cars. Maybe because a lot of ICE cars do not display the fuel usage or estimated range. So, as I am sure ICE owners are aware, when you fill up an ICE car the range on a full tank will change depending on your usage.
An EV is smarter as it remembers past usage. So, when you charge to 100% the estimated range will change based on that usage history. It will also change as you drive the car after charging. The battery capacity has not changed. For instance, I can leave home with an estimated range of 425km. After travelling on an Expressway at 110/115 Km/H during a 400 km round trip with some city traffic midway, I am lucky to get 365km range and have to do a top up on the way home.
These are some of the items that will impact on the computed estimate range:
I have found that the Drive Mode Setting has a significant impact on estimated range.
As an example, switching from Sport to Eco mode in my HI5 AWD adds around 6.5% to the estimated range. Switching from Normal to Eco adds around 3.2% to estimated range. Or, vice versa decreases estimated range.
These are my car's range estimates from the last two charges for each Mode.
Usage before Charge 1 was local, a lot of short runs of 1 to 3kms. Charge 2 was after a day of driving regional country roads with the highest speed being 105km/hr.
Car is usually in ECO mode, Regen3 and Auto. I select Sports only for overtaking or moving into tricky situations like roundabouts, entering busy roads etc.

These are some of the items that will impact on the computed estimate range:
- Your driving style
- Previous drive road conditions (average speed, traffic, hills, road surface (rolling resistance) etc)
- Usage of accessories like air conditioning, fan, headlights etc.
- Ambient air temperature
- Load in the car, weight of driver and passengers + any cargo etc. Some of the EV apps actually ask you to add any cargo weight.
- Regen setting
- Drive Mode setting
