I've had a 2021 AT manual for a couple of weeks, and just realised why the fuel gauge on 3 bars was still showing a range of 80 mile. And the fuel level seemed to drop fast.
The last bar on the gauge accounts for 3.6 litres of fuel. That leaves (18.8-3.6) / 8 per bar for the 8 other bars, which equals 1.9 litres for each of the non-reserve bars.
The first 8 bars are used up faster. The last one (reserve) is almost equivalent to two bars. Which also explains why they divided it into 9, rather than 10.
I'm finding some of the Honda design logic somewhat bizarre!
