Other than that the efficiency should be pretty comparable.

E.g. I would expect a modern Toyota Corolla or Camry to get almost the same mpg as the hybrid counterpart at 90mph.
i doubt that. normal corolla is rated at 40 highway epa. thats at the 60mph moderate test speed. my gfs corolla hybrid gets about 42 mpg with cruise control at 90mph. no way a normal corolla rated at 40 epa highway is boosting up to 42 at 90...
