So, assuming the same total number of vehicles is sold and used, then the mix of p% full EVs + (100 - p)% ICE vehicles can be better than the entirely hybrid fleet when 80 p + 250 (1 - p) < 180 170 p > 70 p > 7/17 ≈ 41% So 1 EV and 1.5 ICE are roughly equal to 2.5 hybrids. And anything more is an improvement.
