I suppose what I want is a carefully designed radiator, don't care what size, where a small amount of air entering the engine room provides as much cooling as possible. Maybe a compact, three row radiator behind a small grille opening would work.
The Insight has the exhaust manifold integrated into the head for better exhaust heat retention and faster warmup. The downside of that, I'd imagine, is the need for more airflow across the radiator once the car is warm.

That was my thoughts too. I have a HD cooling system in my cars and blocking the grille is negligible to engine temp. I have to wonder if the light duty system would require me to remove the grille block sometimes.
