Not puzzling to me - hybrids lower emissions significantly as they optimise the running of the ICE, both how long and at what load it runs. The Toyota system augments the ICE significantly in low load / idle scenarios and plays a huge part in the overall emissions. One example is where the ICE warms up in "low emissions" mode while the electric motor / HV battery propels the vehicle.
From a reliability standpoint, these observations are no surprise to me - how many articles have I read on this forum and others about faults in the Honda IMA hybrid systems (mainly batteries), whereas the Toyotas rarely have issues. Also, how many Prius engines have needed EGR cleanouts to make them run properly?
I know that I may seem biased as I own 2 hybrid Lexus vehicles, but the technology seems vastly superior to the Honda IMA.
