I also considered kinda odd that GM went with the V8 instead of a V6 in the hybrid layout. Well, the electric motor would be supposed to overcome the lower power either in highway or higher load conditions...

Turbocharging an engine with Atkinson-effect cams, like it's usual in hybrids, is harder due to some backpressure at the intake manifold, but a supercharger may be useful. Until mid-50s it was not unusual to use superchargers in industrial and marine engines which got a longer intake valve timing, as a measure to overcome the lower dynamic compression issue.
