If you mean just while driving then no, it'll take slightly more energy to speed up the heavier flywheel to cruise speed, but once there, it takes basically no extra energy to keep it going around at steady speed.
You get less engine braking with a heavier flywheel because the drag of the drivetrain is being acted on by the energy stored in the flywheel's spinning mass. Less spinning mass=less force counteracting the wheels=more engine braking.
