Hi Amar what Stuwit46 has said is dead right but don’t forget the range changes with your settings, so upon switching on the car will always be in N2, normal mode with regen 2 braking, if you change that to E Eco mode you could see any thing from 10 -18 miles more on the range depending on the state of charge, also you need to make sure everything is switched off when checking this as just having the heater on now it’s getting colder can reduce your range reading by 10 miles or more I’m sure Stuart will agree with me on this.
Now here’s a little tip if you have the exclusive model with the heated front seats switch them on doesn’t seem to affect the range much at all. so HVAC off seats on cosy, but you also need to switch off the re-cir switch or crack the window open a touch to help stop the windows misting up.
