So these turbo engine vehicles might get better fuel economy in stop and go driving, but worse in steady cruise?

I know Toyota gave the Gen III and IV Prius a larger displacement than the Gen I and II. Displacement must not be such a huge economy penalty as long as you can keep the engine near the BSFC sweet spot.
