Drove to mk and back yesterday( train to London).
Car charged to 80 % as usual when we left.
Down to 43% when we got in for the return journey. Normally if top up just to be on safe side but wife had a migraine.
On the way out I was a little heavy footed. Nothing significant. No more than 63 in a 60, but didn't hang about getting to 63.
On way back to partly to conserve power , partly for nicer ride for the migraine was in eco mode and a lot lighter footed .Probably top speed 55 , mostly 50 on the 60 road, pulled over once to let a couple of cars pass , but it was quiet. Anyway about 17% left in the tank. Just shows how much you can save with a little care. Don't think there was a significant temperature difference, not mostly uphill one way. I guess about 10 % left if we deduct allow for 3% either way.
