How this estimate works
We start with the vehicle’s published range band, multiply it by the battery available above a 10% reserve, then apply an illustrative driving factor: City ×1.05, Mixed ×1.00, Highway ×0.85. Results are rounded to 5 km.
These factors are Chargespot assumptions, not measured efficiency for these vehicles. This is a way to explore battery and driving choices. Weather, terrain, speed, traffic, battery ageing and cabin cooling are not modelled. It is not a route forecast or a promise that you can reach a destination.
