Why did they go fully open-wheel when aiming for higher efficiency? I always thought that the wheels produce some brutal drag.

In this kind of series the tyre’s overheating and degradation characteristics are carefully designed in to them. The factory has taken in to account covered/uncovered airflow on the wheel.

You control overheating by tuning camber and caster.
