I weirdly gained more range after a 30 mile round trip. Drove for a coffee this afternoon after the car had sat for a week, didn’t do anything extra special to drive in an eco friendly way and had 270 miles range left when I parked up. When I started the car up to drive the 15 miles back home, it said 320 miles and the needle on the tank was at the max. In all the 4 years of ownership the max I’ve ever gotten is 310 miles so it surprised me.
I’m aware that the car will update according to long term mpg, but this really stumped me. Is there a timeframe that it updates on, or is it a glitch? Was parked on the flat so all I can think is that it is due to the saddle design of the fuel tank or something like that.
