Example:
2020 models, 4dr non-hybrid, naturally aspirated
Honda civic 4dr, 2.0 cvt, 30/33/38
Nissan versa, 1.6 cvt, 32/35/40
Toyota camry, 2.5 8spd, 29/34/41

That does illustrate the main point I was making in the beginning: that the common claim that smaller engines are underpowered and therefore less efficient is not true, or "NEARLY irrelevant".
Interestingly your numbers there do show a possible correlation between bigger engines being less efficient in city driving.
