In addition to the other downsides of wheel motors, I'd think that there'd be an efficiency hit. You need a larger and heavier wheel to house the motor, and that means more inertia to get that wheel rolling. Though I suppose that perhaps some of that might be offset by drivetrain losses in a more conventional layout.
I've noticed that on EVs where larger styled wheels are optional, the longest WLTP range - by a small amount - is listed for models with simple 15" or similar stamped steel wheels. .
