You misread my post @kezo 😂 I said that all the non-motorway driving on the outward run was in EV, but that was just about 10 of the 40 miles. It felt as though a lot of the 30 miles on the motorway was too, but it couldn’t have been as I still had about 20 miles left when I arrived. As we’ve discussed, the switch from EV to petrol is thankfully imperceptible.
The return journey was also in Auto but seemed to be running in EV until it ran out of puff. I’ve no idea how many miles I did on electric but it was showing 38 when I left, I gained 2 x 2 miles on the way back and, of course, there’s a bit from the 15% that the car holds in reserve.
I can’t possibly have achieved 80mpg. As discussed, the ‘real mpg equivalent’ is always going to be less than the fuel computer states as it takes no account of the cost of charging. If we say that the fuel computer averaged 65mpg (70 out, 60 back) then the mpg equivalent has to minus out the charge cost in petrol equivalent. I’m confident I now know how to work all this out but I can’t do it until I put petrol in, and I haven’t used enough of the stuff to warrant a pit stop yet. Tomorrow’s journeys will all be in EV only so I won’t get a figure for yesterday alone.
