'Moonroof' is just a merketing term coined by Ford in the 70's. Anyone who pretends there is a difference is silly.
It's actually that. It is a hard definition. Anyone who doesn't adhere to those definitions is just ignorant of them.
Actually, all moonroofs are sunroofs, but not all sunroofs are moonroofs. (Just like all squares are rectangles but not all rectangles are squares.) It is proper and correct to call a moonroof a "sunroof" because a moonroof is simply a specific sub-category of sunroof. It would not be correct, however, to call the fiberglass sunroof in my 951 a moonroof.

A moonroof is a glass roof. A sunroof is a metal roof.
I have not found any controversy on those definitions until this thread.![]()
Those are incorrect definitions.
A sunroof is a roof panel that opens (a simple metal roof is, by definition, fixed in place). "Moonroof" is a term invented in 1973 by Ford Motor Company to describe the glass sunroof they installed in the 1973 Lincoln Continental Mark IV.
I say again, all moonroofs are sunroofs, but not all sunroofs are moonroofs.

Not really.
"Moonroof" was just a marketing term. Those 1973 "Moonroofs"? Lincoln sent the cars to an aftermarket company to have them installed. The installation company? American SUNROOF Company.
So there's really not a hard, fast definition, and either is correct. There is no difference between a sunroof and a moonroof, they are exactly the same thing, and either term is correct. There are certainly different types, but for pretty much all the electric ones, either term is correct. Ford uses Moonroof. GM uses Sunroof. Same thing.
