Many thanks for the very useful input from posters.

As the EFB batteries this car uses are very expensive, I shall replace the present original battery with either an ordinary lead acid or a 40AH LiFePo in the next 2 months.

Present battery only holds 12.2 volts but have not had any issues starting. Maybe it is the sheer size of the thing.

I have experimented with the stop/start switched both on and off and I am not seeing any difference in fuel economy almost certainly due to the fact I rarely ever stop.

When coasting in gear with the stop/start activated I can feel the car slowing down more rapidly than when the stop/start is not activated. The battery voltage climbs from 12.2 to 14.5 volts during this period.

I have just run a full tank of fuel through the car and the mpg via in car meter is 60.8 US / 73 IMP.
The calculated MPG is 62.9 US / 75.5 IMP.

This would appear to tie in with other posters comments that the car computer under reports mpg.

All in all this is one serious ECO car.

I have 2 relatives in Toyota Auris and Yaris Hybrids that have never seen these figures.
